If your Mac is running slow or appears to be frozen, there are a few things you can do to try and fix the problem. Here are some troubleshooting steps you can take:
Check your hard drive space:
If your Mac is running low on hard drive space, it can slow down or freeze. Check how much space you have left by clicking on the Apple menu in the top left corner of your screen, selecting "About This Mac," and then clicking on the "Storage" tab. If you're running low on space, try deleting some files or moving them to an external hard drive.
Restart your Mac:
Sometimes, all it takes is a simple restart to fix a frozen or slow Mac. Click on the Apple menu in the top left corner of your screen and select "Restart."
Close unused applications:
If you have too many applications open at once, your Mac may slow down or freeze. Close any applications you're not using by clicking on the application name in the top left corner of your screen and selecting "Quit."
Update your software:
Make sure you're running the latest version of macOS and any applications you use regularly. To check for updates, click on the Apple menu in the top left corner of your screen and select "System Preferences," then click on "Software Update."
Remove unwanted apps and files:
Unwanted files and applications can take up valuable disk space and slow down your Mac. To remove unwanted apps, click and hold on the app icon in the Launchpad until it starts to jiggle, then click the "X" button to delete it. To remove unwanted files, try using a cleaning app like CleanMyMac or manually deleting files you no longer need.
Reset the PRAM/NVRAM:
PRAM/NVRAM is a small amount of memory that stores settings related to your Mac's startup disk, display, and other functions. Resetting it can sometimes fix slow or frozen Mac issues. To reset the PRAM/NVRAM, turn off your Mac, then press and hold the Command + Option + P + R keys while turning your Mac back on.
If none of these steps solve your slow or frozen Mac issue, you may want to consider taking your Mac to an Apple Store or authorized repair center for further assistance.
