Speedtest was 'very slow' on my Macbook Pro 2015 and super quick on iPhone 8, it has been painful and driving me nuts!! It usually got quicker throughout the day, but unbearable in the morning. After reading the above post about the VPN, I searched (cmd + spacebar) for 'vpn'. Check Available Disk Space. This first fix can be done before you even attempt to install the update. On my 2014 Macbook pro I get 400 Mbps on fast.com and iperf3 shows 360-380 Mbps. I recently bought a new Macbook pro 2018 (touch bar) and I am getting a max of 120 Mbps and it drops to as low as 12 Mbps. IPerf3 similar slow downs. But randomly it picks up again to 250 Mbps and then 350 Mpbs. Is Your MacBook Pro Running Slow? Here Are Some Things to Try: Editors note: this post was originally published in July 2015 and was updated in 2017 to reflect new reviews and experiences. Any Apple computer will start to slow down over time, but there are steps you can take to keep your MacBook Pro speedy.

One second, two seconds…finally you started to cry out: “Why is my Mac laptop so slow?”

Though Mac machines are generally considered to be faster than Windows PCs, it’s not uncommon for a Mac to start acting up with symptoms like taking forever to boot, freezing while opening an app, or mouse cursor becoming unresponsive, etc.

You are not alone!

As Apple advocates for more than a decade, we’ve probably encountered more performance issues than you. Fortunately, we were able to fix most of them, and today we still use our old MacBooks from time to time.

Here we are going to share the fixes we’ve discovered along the way, and you are going to learn:

• The four main reasons why a Mac can run slow.
• Solutions to fix your slow Macbook and make it fast again.
• Bonus tips to mitigate the risk of future slow-downs.

The tips below should also apply to other types of Macs such as iMac, MacBook Air, Mac Pro/Mini, etc. Use the Table of Contents below for better navigation.

Why is My Macbook Pro so Slow?

Whether you own an old 2012 MacBook Pro, or a shiny new 15-inch 2017 MacBook Pro with 512GB flash storage, over time it can run slowly. There could be so many causes, but in general, they all fall into the following four categories.

1. Personal Habits. If you keep your Mac running all the time, let too many apps join the fun on startup, or multitask with loads of heavy applications open — more often than not, your Mac will hang.

2. macOS System. A newer macOS usually performs better than an old one, but no system is perfect. You may experience firmware or permission issues that impede performance as well.

3. Software Issues. Apps, whether pre-installed or third-party ones downloaded elsewhere, can consume lots of system resources when used improperly, which eventually will slow down a Mac.

4. Outdated Hardware. Every piece of hardware has a lifespan; your Macbook is no exception. An outdated hard drive or lack of RAM can be the bottleneck of your machine.

These are just the high-level reasons. Check out this infographic that outlines 26 specific reasons why a Mac might run slowly. You may find what’s hanging up your machine.

Note: If your MacBook Pro is slow only after updating to the latest macOS version (i.e. macOS 11.o Big Sur), the best fix would be restarting your machine several times since the new macOS needs time to re-index or update data saved in the disk drive. For example, Photos can take a while to update the entire picture library; Spotlight re-indexing tends to be time-consuming as well.

Moving on… The Solutions!

Now that I’ve learned the reasons behind a slow mac, what should I do to fix it? We break down the solutions into two categories:

• The Manual Methods: best for those who are tech-savvy and don’t mind taking the time to do so. We list a number of things you can do manually to fix your slow Mac.
• The Quick Technique: best for beginners or those of you don’t have time to implement manual fixes. We recommend using CleanMyMac X to scan your Mac and fix all issues the app finds.

Note though, the solutions we suggest below only work when your Mac can boot up normally. If it cannot, or you hear strange sounds coming from the machine (particularly from the internal Mac hard drive), contact Apple support or schedule an appointment with a Genius Bar in your area.

How to Fix a Slow Macbook Pro: The Manual Methods (4-6 hours)

The methods introduced below are the best manual fixes we have explored. The order is based on a combination of estimated time required and expected effectiveness after implementation. They are, however, by no means the only solutions, and you don’t have to complete all the methods as it’s very unlikely you’ll be able to. Meanwhile, read this checklist on how to speed up Macbook Pro.

Method 1: Manage login items to tune startup times

• Time: 5-10 minutes
• Effectiveness: Low-Moderate

When to use: your Macbook Pro runs extremely slow on startup.

Why it helps: disabling login items (auto-run applications or services) you rarely use helps your Mac better allocate system resources to load the processes you do use, you’ll reach the login or desktop screen more quickly.

How to do: follow the steps in this YouTube video.

Method 2: Clear off cluttered Desktop items & Dashboard widgets

• Time: 20-30 minutes
• Effectiveness: Moderate

When to use: your Macbook Pro takes a bit longer to load the first screen after startup.

Why it helps: because macOS treats each desktop item (be it a file, a Dock application, or a Dashboard widget) as a small task, it uses resources to load it when starting up. Reducing the number of such items can make the first screen show up quicker.

How to do:

• Keep fewer files on Mac desktop. Try to group those files you saved directly on desktop, put them into few folders, and if possible move them folders like Documents or Pictures.
• ​Remove unnecessary apps from the Dock. Move your mouse cursor to an app, right-click, select Options and click Remove from Dock.
• Clear unused Dashboard widgets. Go to Dashboard, press option button and move your cursor the widget you don’t want to show, click “x” on the upper left corner.

Method 3: Clean up hard drive to free up more disk space

• Time: 1-2 hours
• Effectiveness: High

When to use: your Macbook Pro is running out of space, and it slows down or freezes more frequently.

Why it helps: macOS utilizes free hard disk space as “virtual memory” in addition to RAM (Random Access Memory). If your MacBook Pro is running out of storage, that means little virtual memory can be used by the system if needed. This may cause your Mac to freeze more frequently — even when you just launch a few apps. In general, having at least 10% of free disk space can often prevent the problem from happening.

How to do: try the tricks below.

Note: if you want to save time, CleanMyMac is a nice tool for this purpose. It automatically detects and cleans extra junks that can take up gigabytes of disk space.

• Empty Mac Trash bin.
• Clear web browser (Safari, Chrome, Firefox, etc.) files such as caches, history, plugins, etc.
• Uninstall unused applications.
• Remove unused language packs on your Mac.
• Go to the “Movies” and “Pictures” folders, delete large or duplicate items you’ve already backed up. You can use Gemini 2 to find them more quickly.
• Go to the “Download” folder and get rid of items you don’t need.
• Transfer big files or folders to your external hard drive or another computer.
• And other ways you can think of to lighten your Mac hard drive.

Method 4: Verify and repair disk permissions with Disk Utility

• Time: 15 minutes
• Effectiveness: Moderate

Update: beginning with OS X El Capitan (including macOS Sierra), it’s no longer necessary to verify or repair permissions as Apple has made system file permissions to be automatically protected.

When to use: your Macbook has issues launching some applications, and doing so slows down your Mac.

Why it helps: corrupted or damaged file permissions can cause certain applications to run abnormally or unable to run at all, thus affecting the overall Mac performance. Matt from CNET brought his sluggish Mac back to health using this method. Note: it’s harmless to repair file permissions.

How to do: check out this Apple support article or this YouTube video for a step by step guide.

Method 5: Lighten web browsers to improve Internet surfing

• Time: 20 minutes
• Effectiveness: Low-Moderate

When to use: your web browser (Safari, Chrome, or Firefox, etc.) just seems stubborn to load pages or becomes unresponsive.

Why it helps: web browsers are notorious for dragging down computer performance after extended use. By implementing the things below, you can expect a much smoother net surfing experience.

How to do:

• Have fewer tabs open at once, especially when you read online magazine sites which tend to have heavy pages (ads, flash queries, etc.)
• Remove those browser extensions you rarely use — (Safari here, Chrome here, Firefox here).
• Clear browser cache, cookies, plug-ins, and history. This can also free up much hard disk space. See this guide for how.
• Get rid of Adware (flash ads), this article from the Boyce Blog is worth a glance.
• Safari tends to eat up more RAM as time goes by, but a simple quit and restart will help it get back to “normal.”
• Reinstall your web browser if necessary.

Method 6: Identify and knock out heavy apps/processes with Activity Monitor

• Time: 15 minutes
• Effectiveness: Moderate

When to use: your Macbook starts to run slower after opening several applications, but you have no idea which application is the culprit.

Why it helps: Activity Monitor is a task manager on Mac that shows you both running applications and inactive processes. The list allows you to have a clear understanding of which one is devouring too many system resources (CPU, memory, disk, network, etc). Once you find the culprit, you can also use Activity Monitor to quit or force quit the app/process easily.

How to do: see this video from MacWorld.

Method 7: Reset SMC and NVRAM to fix odd hardware errors

• Time: 30 minutes
• Effectiveness: Moderate-High

When to use: your Macbook Pro acts oddly (it takes forever to figure out which disk to boot from, it’s slow to shut down, the fan is running non-stop, screenshots are not adjusting correctly, battery indicator lights are behaving incorrectly, etc.), and overall your Mac performs poorly.

Why it helps: NVRAM (or PRAM in older Macs) stores certain settings in a location that macOS can access quickly. SMC has roles in controlling thermal and power management on Mac. Resetting NVRAM and SMC helps resolve the issues mentioned above, and it’s a safe thing to do.

Improve Macbook Pro Speed

How to do: check out this video for how to properly reset NVRAM and this video for SMC.

Method 8: Update your Macbook Pro to latest macOS version

Macbook Pro Speed Up

• Time: 1-2 hours
• Effectiveness: Moderate

When to use: your Mac is still running an older macOS version (e.g. High Sierra or Mojave), and you meet the basic requirements of the new upgrade — latest macOS 11.0 Big Sur, you need at least 2 GB of RAM and 15 GB of free space on the drive.

Why it helps: a newer macOS version typically runs faster than an older one, though it depends on the model of your Mac machine.

How to do: there are a few things you need to check before getting ready to update your MacBook to macOS Big Sur. For example, check whether your model is compatible, whether you have enough storage space, and most importantly backup your data, etc.

Method 9: Disable fancy features in exchange for performance

• Time: 15 minutes
• Effectiveness: Low-Moderate

When to use: best for those who are using an older Mac with limited hardware configuration, and don’t particularly favor fancy interfaces and visual effects.

Download Speed Slow On Mac

Why it helps: by disabling or turning off features like Notifications, Transparency, and Animations, Magnification, File Vault, etc., you can boost Mac performance since fewer system resources will be used.

How to do:

• Reduce Transparency and Animations.
• Minimize windows using and change the Genie Effect to Scale Effect.
• Optimize Notification center and turn off real-time notifications you don’t need.
• Disable Launchpad effects.
• Get rid of preference panes. Go to System Preferences, locate a pane you want to remove, right-click (or Control-click), then remove it from the pop-up menu. It may ask you to type the admin password.
• Disable FileVault Disk Encryption option.

Method 10: Upgrade hardware (RAM, SSD) to have a real boost

• Time: it depends (at least 2 hours)
• Effectiveness: High

When to use: you are using an old Macbook Pro, and you’ve tried every method you can to fix your slow Mac but it’s still slow.

Why it helps: adding more memory (RAM) or replacing your HDD (hard disk drive) with a new SSD (solid-state drive) will give your Mac a real boost in performance. The only con is the upgrades can be pricey.

How to do:

Note: whether you choose to upgrade RAM or SSD, you’ll need to open the bottom case of your MacBook, a screwdriver may worth adding to your shopping cart as it will help you remove the screws much faster.

Add extra RAM: depending on your MacBook model, the RAM that best fits may be different. Learn more from our review here. It’s best to also check out this page to see memory specifications for your Macbook Pro model. It comes with an illustrated guide on how to replace the memory. This video from CNET is also worth checking out.

​Upgrade to an SSD: If you still want to use your old MacBook Pro for professional work (video/graphic editing, 3D modeling, etc.), the best option is to replace the hard drive with a speedy SSD, see our picks here. Once you purchase your desired SSD, watch this video for how to install it step by step.

How to Fix a Slow Macbook Pro: The Quick Technique (5-10 minutes)

The manual methods can be quite time-consuming to implement and may require you to have a certain level of technical skills. Fortunately, we’ve got two awesome Mac optimization apps that can save you time fixing your slow Mac.

Option 1: Using CleanMyMac X to scan & clean up your MacBook Pro

CleanMyMac X – an app developed by MacPaw and rated as the winner in this Mac cleaner software review. As its name indicates, this app aims to help you clean your Mac and free up more storage space. It does this by locating junks and unnecessary files via analyzing your macOS system: Photos, Mail attachments, large and old files, etc. In addition, you can use the app to batch uninstall unwanted programs, and permanently erase files that are private to you. CleanMyMac is super sleek and intuitive, just hit Scan to get started and then Clean to fix issues.

Option 2: Using MacBooster to improve your Mac’s overall performance

MacBooster – an app developed by the IObit team. This app stands out for its all-in-one concept. It includes a handful of useful utilities that can monitor the overall status of your Mac system. The Virus & Malware Scan module, for example, helps identify possible security threats and removes malware. To get started, simply run a quick System Status scan and it will find and suggest fixes. You can also move on to the Tools sections for further optimization.

Tips to Avoid Mac Running Slow

• Shut down your Mac when you are away. Restart regularly.
• Do not save everything to the desktop or the main drive (where your system files are stored). A full boot volume can lead to a slow startup and other performance issues.
• Try not to install third-party apps that you don’t need. They can take a lot of precious disk space as well as system resources while running. Also, outdated apps can have problems running due to macOS incompatibility. Learn how to uninstall Mac apps the right way.
• Use a lightweight browser like Safari or Chrome, Firefox tends to slow down over time (Safari or Chrome acts up too, sometimes). Avoid opening too many tabs at once while you are browsing the web, try not install too many extensions/plugins.
• Clean up the hard drive (especially when the startup disk is almost full) on a regular basis, e.g. once a month. You can do this manually, or use a tool (like the ones we recommend above).
• Always keep your software up-to-date if possible, ideally you should always install apps from App Store or the software provider’s official website, instead of third-party download sites which may bundle Adware or malware.
• If you regularly use your MacBook Pro for work at an office, consider elevating it with a laptop stand or a cooling pad as this helps avoid overheating issues.
• Don’t immediately update your Mac to the latest macOS version (to date, it is macOS 11.0 Big Sur). Let the early birds test out first, then choose to update when you feel it’s the right time.
• Don’t blame your Mac when it’s slow. Figure out the reason first and fix it right away. You never know when a small issue can evolve into a serious one.

Are you experiencing those Wi-Fi problems with your Mac? For example, your MacBook Pro won’t connect to wifi, connected but no Internet or the network speed is super slow, etc.

Our smartphones may be equipped with the latest wireless data capabilities, but our MacBooks definitely aren’t. We rely on WiFi to do our daily work, and when it inevitably experiences an error of some sort, all you want to do is throw your hands in the air.

After all, WiFi frequently seems to be on the more technical end of things, shrouded in mysterious terms like “DNS”, “modem”, and “IP address”. It can be a bit intimidating to try and fix without worrying that you’re either doing nothing or making the problem worse.

But no one likes mindlessly refreshing a webpage and hoping the WiFi fixes itself in the meantime, so in this guide, we’ll show you a few ways you can take matters into your own hands to find a solution.

Do You Know?

You can troubleshoot network connections in the office or at home with WiFi Explorer. It’s an awesome app that shows you what’s going on with your network and helps you fix it when needed. The app offers a range of extensive details about all your Mac networks in the vicinity, including their band, signal quality, range, security status etc.

Your Internet Service Provider (ISP) is what determines your maximum internet speed, but your usage at home is what ultimately determines how well your connection functions. Whatever your provider advertises is always going to be more than the rates you actually get, but you can always make adjustments on your end to get things running faster.

Bandwidth is not the same as Internet speed. The Internet speed is how fast data can travel on your network, whereas your bandwidth determines the volume of information that can travel at that speed. A larger amount of bandwidth means you can request more data at once, which will make your connection seem faster, but it’s not worth paying for if you don’t use your Mac for much beyond Facebook and email.

It’s important to connect to secure networks even if it means using a Virtual Private Network (VPN) or proxy. While it’s tempting to use the free coffee shop WiFi, the lack of protective password puts your computer at risk because malicious users can use the shared network and attempt to break in. If you must use one of these networks, a proxy or VPN can protect your computer by isolating it from the other connections.

Connection Problems

Issue 1: Physical router interference

Cause: A router sends electronic waves, but these can be impeded by thick walls or other large blockages such as a row of metal filing cabinets.

How to Fix: If your router is currently buried behind a file cabinet, in a closet, or otherwise awkwardly placed you should move it to a more open and central location. If your router is already in a fairly clear area, consider where you’re sitting. Can you minimize the amount of distance between you and the router, or otherwise move closer?

Alternatively, consider purchasing an extended if you can’t seem to move the router to a location without too much interference.

Issue 2: Neighborly router interference

Cause: As we said earlier, a router sends electronic waves. These waves occur at certain frequencies and can be interfered with by other electronic devices such as microwaves or your neighbor’s router.

How to Fix: Most routers come pre-calibrated to certain frequencies or contain software that helps them pick the best channel. You can manually change the channel though by following a few steps.

• Step 1: Find out your router’s IP address. This is usually printed on the router, but you can also check in System Preferences > Network > Advanced > TCP/IP > Router;
• Step 2: Copy the IP address into the address bar of your browser and hit enter. You’ll be directed to your router’s settings;
• Step 3: Select the channel you want. Make sure to choose a channel 5 to 7 away from the original, since many frequencies overlap;
• Step 4: Use Wireless Diagnostics to monitor which frequencies make the biggest difference in your wireless signal.

You can get open wireless diagnostics by navigating to Spotlight and then beginning to type “wireless diagnostics”. It should be the first option.

Open the app and click “Continue” to start diagnosing.

Issue 3: MacBook Pro or router failure

Cause: When there doesn’t seem to any conceivable reason your WiFi shouldn’t work, it’s not your fault. Sometimes the MacBook Pro, the router, or both experience an unexpected error that’s invisible to the eye and impossible to figure out exactly what went wrong.

How to Fix: Your best bet at solving this type of problem comes in two parts: your computer, and your router. Follow these steps:

Step 1: Turn off the wifi on your computer from the menu bar along the top;

Step 2: Turn off your router by physically disconnecting it (or pressing the power button if it has one) so that all the light turn off;

Step 3: Restart your MacBook from the Apple menu in the top left of the menu bar;

Step 4: Once your Mac has restarted, turn the router back on. You’ll need to wait 2-5 minutes for all of the lights to come on and for the signal to begin sending again

Step 5: Turn your Mac’s WiFi back on, and allow it to connect to the network.

While this method isn’t guaranteed to work every time, it often solves mysterious wireless issues and with a little luck, your problem is minor and will be resolved with a bit of restarting.

Problems Once Connected

Issue 4: WiFi connection is spotty

Cause: If we’ve said it once, we’ve said it a million times: your router transmits waves, and when these are weak at your location, you’re going to have connection issues. In this case, you may have been able to connect to the network but now service is patchy at best. The cause is simple — you’re too far away for the frequency you’re trying to use.

How to Fix: There are two different ways you can fix this issue. First, move closer to the router if you can. This is the easiest way to attempt to solve the problem and maybe all you need to do.

The second way is to use a different frequency band than you normally would. By defaults, your router uses the 2.4GHz band, which is weaker than the 5GHz many router models have available. If your router supports 5GHz, you should switch to this instead- it usually appears as a different network in your WiFi list, with a “5GHz” or “5G” as part of the name.

For example:

If you have a large home, an extender might be a more practical solution. It will amplify the signal from your router so that it can reach the areas of your house that usually suffer from poor coverage.

Issue 5: WiFi connection is very slow

Cause: If things have suddenly slowed down, it’s highly likely you can point to another person to take the blame — someone else is eating up your bandwidth! Make sure to check your own computer first though, especially if you’re running multiple programs in the background.

How to Fix: The easiest way to figure out the culprit is by running a quick scan using Advanced Network Care, it’ll show you the connection speed issues found with your current network and fix it if needed. An alternative is a Wifi Explorer as we already mentioned above.

However, you can also fix that manually. Bandwidth refers to the volume of data that can be transmitted over your WiFi connection. Certain apps can require larger bandwidth and thus restrict the data available to everyone else.

If this occurs in your home, the first step is to check your own applications. The most common offenders are multiplayer video games, video-intensive apps, or files that are uploading and downloading. If your Mac isn’t running anything strenuous, then ask the others in the household if they are.

While you can’t get more bandwidth without paying for it, you can ask anyone on the network to limit which applications they use at one time. In the worst-case scenario, you’ll need to wait a few minutes while a download finishes or until the other person is done working.
