Hi! I’m Chris Gardner, Your Tech Coach giving you Practical Help for Your Digital Life® since 1996. Since you don’t need to completely re-install macOS, the Apple Support folks are your best bet to get just that app re-installed. If you are still having trouble then you’ll need to visit Apple Support – connect with a service tech who will walk you through troubleshooting and fixing the issue with the calendar app.Īpple doesn’t make the apps that come with a Mac available individually, as they’re part of the macOS installation. Most likely the app will start working again normally. If it opens ok, go ahead and restart the computer normally and try the calendar app again. When you’ve started your Mac in safe mode, open the calendar app. Then, you can troubleshoot the calendar app if it’s still not working by starting your Mac in safe mode.Īpple has complete instructions for using Safe mode at. In Finder > Applications >Utilities open Disk Utility and click the First Aid icon at the top to run it and correct any hard drive errors.
If your Mac calendar app isn’t working, probably the first thing you should do is run First Aid on your Mac.
