What to do when MacBook not opening apps
After understanding the possible causes for MacBook not opening apps, we are moving to know how to fix this issue so that you can use the apps you want on your Mac without problems. Follow the methods below to troubleshoot the Mac won't open apps issue now.

- Restart your Mac
- Ensure you have permission for the app
- Change security settings to allow downloaded app
- Update or reinstall the app
Force quit the app
Perhaps you have already opened the app, but it gets frozen so that when you click the app icon, it doesn't respond. You can force quit the app on Mac and reopen it. By opening the Force Quit window from the Apple menu, you can also check whether the app is already in use but stuck.
Restart your Mac
If the problematic app hasn't been opened or forced to quit it not working, it perhaps relates to the system crash on your Mac, then restarting your Mac is a quick fix to give your Mac a fresh start.
Ensure you have permission for the app
If you share the Mac with others or you have several accounts, you should make sure you have permission for the app, either allowed by the administrator or logged in with the admin account.
You can check the account type by heading to System Settings > Users & Groups. If you are the admin, you should have all privileges to apps on your Mac. But if not, contact your admin to let you access the desired apps.
Change security settings to allow downloaded app
You can install apps on Mac from App Store or third-party channels. When you download an app out of the App Store, be it an identified developer or not, you may encounter the error to open the app to use, along with some error messages like "App cannot be opened because it is from an unidentified developer."
For the sake of security, Apple uses the mechanism Gatekeeper to check the download app before opening it, it sometimes could be inconvenient given that it may prevent you from opening a wanted app, however, you can override the security settings and open the app anywhere.
Allow open apps from identified developers:
- Head to the Apple menu > System Settings > Privacy & Security.
- Under Security, tick App Store and identified developers.
Allow open apps from unidentified developers:
- Head to Finder > Applications, and right-click the app to choose Open.
- Go to the Apple menu > System Settings > Privacy & Security, click Open Anyway under Security on a box saying "[app name]" was blocked from use…
- Run the command "sudo spctl –master-disable" in the Terminal and check Anywhere under Allow apps downloaded from in Privacy & Security. You'd better disable this option after opening the app with the command "sudo spctl –master-enable."
Update or reinstall the app
Have you already updated your Mac to macOS Ventura, the latest version, if the Mac apps not working issue occurs after the macOS update, then it is highly likely that the apps are incompatible with the latest macOS. You should check for app updates from the App Store or the official websites.
Perhaps, the apps are damaged so you can't open them on Mac. The easiest way to reset an app on your Mac is to reinstall the app on your Mac. You can uninstall the app on Mac with iBoysoft MagicMenu, just one right-click, you can remove the app.
