Method 1of 5:

Preventing Freezing

1. Refrain from running more than a few programs at once. While Macs are renowned for their multitasking abilities, any computer will slow down if you have several programs running at once, particularly if they are high-usage programs like video-editing software.
   • The same goes for tabs and windows in browsers.
2. Note programs that cause freezes. Not only will corrupted files, documents, or programs can cause your Mac to freeze or crash, they will do so consistently. If you notice that opening a certain program, file, or document causes your Mac to freeze, delete it or move it off of your Mac (e.g., to an external hard drive).
   • You can force-quit unresponsive programs once you've determined that they cause freezes to return your Mac to its normal state.
3. Empty the trash. Files that you delete go straight to the Trash Can where they will remain until you delete them again, meaning they still take up space. To empty the Trash Can:
   • Click the Trash Can app in your Mac's Dock.
   • Click Empty Trash... in the pop-up menu.
   • Click Empty Trash when prompted.
4. Make sure your apps are up-to-date. Out-of-date apps can cause any device to freeze, be it a MacBook Pro, an iPhone, or a smart TV. You can update Mac apps in the App Store, while third-party apps or programs must be updated by going to the app's webpage and downloading the most recent version.
   • Most programs will alert you upon being opened if there is an update available.
5. Use Safe Mode . Safe Mode will run diagnostic checks on your hard drive and folder structure, and will only load the files necessary for your computer to start. This is helpful if your Mac is freezing on startup.^[1]
   • You can update your Mac from Safe Mode, which may fix your freezing problems if your Mac is using an unsupported version of OS X.
6. Wipe your Mac's files. If all else fails and you simply cannot get your computer to stop freezing, you may need to wipe your drive. You will lose all of the data on your hard disk, so be sure to save everything you need to an external drive or upload it to the cloud.
   • Make sure you try everything else in this article before you even consider wiping your drive.
   • You can install the latest version of MacOS on your Mac after wiping the drive.
