Monosnap for Mac won’t Start? Here’s How to Fix

Monosnap is a great tool to take screenshots and annotate for Mac and Windows. With MacOS updates, sometimes it may not start. You can try reinstalling it, but it may not solve the problem.

Then you need to try removing all files created from it.

Open Terminal in Mac, and run these commands.

rm -rf ~/Library/Application\ Scripts/com.monosnap.monosnap
rm -rf ~/Library/Containers/com.monosnap.monosnap
rm -rf ~/Library/Application\ Scripts/com.monosnap.MonosnapLauncher

If you need to see if any crash reports were generated, run this.

ls ~/Library/Application\ Support/CrashReporter/Monosnap_*.plist

To delete the crash reports,

rm ~/Library/Application\ Support/CrashReporter/Monosnap_*.plist

After that, reinstall Monosnap, and the icon should showup in your menubar.
