Is your MacBook Pro running slowly? There are many reasons why your Mac could be operating at frustratingly slow speeds, from multiple open apps or an outdated OS to a lack of RAM. Read our guide to help you diagnose the common reasons that cause a Mac to run slow and lose speed.

Haven’t restarted

If you have a slow MacBook, one of the most common reasons is that the computer hasn’t been restarted in a while. Restarting the computer clears cached files, closes programs, and gives your memory (RAM) a fresh start. The result will be a system that isn’t spending time hunting through a lot of old data.

Too many open apps

Too many programs starting automatically

There can be programs that start automatically that you might not be aware of, or that were needed at one time, but aren’t needed at start-up now.

Hard disk is too full

When your MacBook is running slowly, it could be that the hard drive is reaching capacity. Your hard drive (HDD) stores not only your operating system and programs, but also your documents, photos, videos, and music. If you’re running low on storage space, there will be a noticeable impact on your Mac’s performance.

If the remaining free space is less than 2GB, it’s time to clean up. Delete any unneeded files, old downloads, and copy the movies and TV shows you can’t live without to an external drive.

If you can’t remove enough items to free your hard disk, consider upgrading to a solid state drive (SSD). Find out more about SSDs.

Outdated OS

To improve the speed of your Mac, be sure to accept automatic operating system updates. The most important reasons to do this are related to security, but having the newest OS will also streamline and improve the performance of your entire system. Operating system upgrades also offer new features and capabilities.

Slow internet connection

The slow speed you’re experiencing might not be your system’s fault! If your internet connection is slow you might experience delayed page loading and a lot of buffering when you try to play videos.

You can do a speed test of your upload and download speeds by finding and running speed test software. If the speed reported is less than the speed you’re paying for, reset your router and modem by unplugging them for two minutes, then restart the router, modem, and computer. Finally, run the speed test again. If your speed remains below the amount you’re paying for, contact your internet service provider (ISP) to see how they can fix the issue.

Not enough RAM

Memory (RAM) works with your storage drive to determine how fast apps respond. If your computer is low on RAM, you will notice programs might be unresponsive, multitasking between applications becomes more difficult, and video or sound can skip or freeze. Because nearly every computer operation relies on RAM, it’s essential to have enough to keep your computer running as quickly and smoothly as possible. To see how much RAM you have in your computer, click on the Apple menu, then select About This Mac.
