Macbook Pro Slow?
Does this sound familiar to you? You're sitting in front of your Macbook Pro surfing the Internet on Safari or working on a project. All of a sudden, you see the spinning beach ball. One second, two seconds...finally you start to cry out: "Why is my Mac laptop so slow?"
Though Macs are generally considered to be faster than Windows PCs, it's not uncommon for your Mac to start acting up with symptoms like: taking forever to boot, freezing while opening an application, or the mouse cursor becoming unresponsive.
You are not alone! As Apple advocates for a decade, we've probably encountered most of the Mac performance issues you may be experiencing. Fortunately we were able to fix them, and today we still use our older Macs daily.
Here we share the fixes we've discovered along the way, and you are going to learn:
- The main reasons why a Mac may run slow.
- Solutions to fix your slow Macbook and make it fast again.
- Bonus tips to mitigate risk of future slow-downs.
Read on by navigating the Table of Contents below. Please note: the tips below may also apply to other type of Macs such as iMac, MacBook Air, Mac Pro/Mini etc.
Why is My Macbook Pro so Slow?
Whether you own an old 2009 Macbook Pro or a shiny 2016 model (with Touch Bar), over time it can run slowly. There are numerous reasons out there, but in general they all fall into the following four categories.
If you keep your Mac running all the time, let too many apps join the fun on startup, or multitask with many heavy applications open -more often than not, your Mac will hang.
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.
Apps, whether pre-installed or downloaded elsewhere, can consume lots of system resources when used improperly, which slows down a Mac.
Everything has a lifespan; your Macbook's hardware is no exception. An outdated hard drive or lack of RAM can be the bottleneck preventing desirable speed.
These are just the high-level reasons. Check out this infographic that outlines 26 specific causes why a Mac might be running slow. You may find what's hanging up your Macbook Pro.
New update: if your MBP is slow only after updating to macOS Sierra, the easiest solution to fix it may be -- wait a day or two. Because the new system usually takes time to re-index or update the data. For example, the Photos app can take a while to update all your photos library; Spotlight reindexing can be time-consuming as well. You may also refer to this Apple guide for Sierra specific troubleshooting tips.
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 you don't mind taking the time to do so. We list a number of things you can do manually to fix it.
- The Quick Technique: best for beginners or those who don't have time to implement the manual fixes. We recommend using an app called CleanMyMac (or MacBooster, as an alternative).
Note: the solutions we provide only work when your Macbook Pro 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 Genius Bar or a local computer repair shop for help immediately.
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 effectiveness to implement. 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 post for a checklist on how to speed up Macbook Pro.
Method 1: Manage login items to tune startup times
Time: 5-10 minutes
When to use: your Macbook Pro runs extremely slow on startup.
Why it helps: disabling login items (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
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 less files on 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 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
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 can cause your Mac freeze frequently -- even when you just open a few apps. Therefore, having a at least ten percent 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 3 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.
- 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
Update: beginning with Mac OS X El Capitan (Version 10.11), it's no longer necessary to verify or repair permissions as Apple has made system file permissions to be automatically protected.
Time: 15 minutes
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
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 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
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 about 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
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 OS X 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.
How to do: check out these two videos for how to properly reset NVRAM and SMC.
Method 8: Update Macbook system to the latest OS X
Time: 1-2 hours
When to use: your Macbook Pro is running an older operating system (e.g. Yosemite or earlier), and you meet the basic requirements of the upgrade -- for El Capitan, you need at least 2GB of memory and 8.8GB of storage space, same with the latest macOS Sierra (source: Apple).
How to do: follow this official guide posted by Apple, or this video tutorial for how to update to latest macOS Sierra (version 10.12). Note: you may need quite some time to download it as it's about 5GB in size. Be patient.
Method 9: Disable fancy features in exchange for performance
Time: 15 minutes
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.
Why it helps: by disabling or turning off features like Notifications, Transparency and Animations, Magnification, File Vault, etc., your can boost Mac performance since less system resources will be used.
How to do:
- Reduce Transparency and Animations.
- Minimize windows using and change 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 admin password.
- Disable FileVault Disk Encryption option.
Method 10: Upgrade hardware (RAM, SSD) to have a real boost
Time: it depends
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:
Add extra RAM: be sure to check out this page to see memory specifications for your Macbook Pro model. It also comes with an illustrated guide on how to replace the memory. You can also watch this CNET video:
Replace with a SSD: follow the steps in this video.
How to Fix a Slow Macbook Pro: The Quick Technique (5-10 minutes)
The manual methods can be quite time-consuming and may require you to have certain level of technical skills. Fortunately, if you want to fix your slow Mac more quickly and easily, here are some tools you can rely on.
Option 1: Using MacBooster to keep your Macbook clean and secure
MacBooster 5 - developed by the IObit team. The software stands out for its all-in-one concept. It integrates a collection of handy and useful tools for monitoring overall status of your Macbook. The Security Risks, for example, helps you identify possible security threats and removes malware.

Option 2: Using CleanMyMac 3 to scan & clean up your Macbook
CleanMyMac 3 - as the name indicates, its core value is to clean your Mac and free up storage space -- by locating junks and unnecessary files through deep scan of the system: Photo/iTunes, Mail attachments, large and old files, etc. In addition, you can use it to batch uninstall unwanted programs, and permanently erase files that are private to you. The app is very sleek and intuitive, just hit Scan to get started and then Clean.
Tips to Avoid Macbook Running Slow
- Shut down your Mac when you are away. Restart regularly.
- Don't save everything to the boot drive (where your system files are stored). A full boot volume can lead to a slow startup and performance problems beyond.
- Try not to install software that you don't need. It can consume much precious disk space. Additionally, over time outdated software can have problems running due to system incompatibility issues.
- Use a lightweight browser like Safari or Chrome. Avoid opening too many tabs at once, and do not add too many browser extensions/plugins.
- Clean up the hard drive on a regular basis, e.g. once a month. You can do it manually or rely on a tool (like the ones we've introduced above).
- Always keep your software up-to-date, and have a good habit of getting software from App Store or the software provider's official website.
- Don't immediately update your Mac to the latest macOS version. Let the early birds test out first. Choose to update when you feel the time is right.
- Don't blame your Mac when it's slow. Figure out the reason and fix it immediately. You never know when a small issue can evolve into a bigger one.
