Much like on a Windows machine, if you’re trying to determine “why won’t my screen recording work?” on a Mac, start by restarting your computer. This may solve the problem, and get you back on the road to successful recordings. If that doesn’t work, try one of these tips.
Make sure that screen recording is enabled
“My Mac won’t let me record my screen! What’s going on?” You may have screen recording disabled. To find out, click on the Apple icon at the top-left corner of your screen and select System Preferences. In the preferences window, click on Security & Privacy and then go to the Privacy tab and click on Screen Recording. This will show you a list of all the apps that you currently allow to record your screen. If your screen-recording software isn’t selected, this is probably why you’re having trouble. Check the box to enable screen recording and you’ll be ready to get started.
Check your available storage
If you’ve recorded your screen but your Mac won’t let you record anymore, it may be a storage issue. Fortunately, it’s pretty easy to check your available storage. Click on the search icon at the top right of your screen and search for “storage.” The first option available should take you to a System Settings window, where you can scroll down and check your available storage. If you don’t have enough storage space on your computer, you may be able to fix the issue by deleting unnecessary files that are taking up a lot of space or exporting them to cloud storage.
Check for system updates
When was the last time you updated your Mac? If it’s been a while, your computer may not be working properly because your system or the app you’re using for screen recording is out of date. Go to the Apple icon at the top left of your screen and click on System Preferences. In the preferences window, choose Software Update. This will allow you to perform any available updates, and then you can try screen recording again.
Try a different screen-recording program
If you’re trying to use a screen recorder that you haven’t used before, or if you’re using an older one that doesn’t work with the latest version of macOS, you may need to opt for a different screen recorder.
