The Mac apps should be working and opening as usual now. When finished updating, relaunch the app(s) which were crashing, they should open fine now and without incident.Wait for the app updates to install on the Mac via App Store.Go to the “Updates” tab, and to fix all apps, choose “Update All” – (You can also individually update specific apps that are crashing on launch by locating them in the list and choosing “Update” on a per app basis).Open the “App Store” application by going to the Apple menu and choosing ‘App Store’.Quit all open apps that are from the Mac App Store (assuming some opened successfully in the first place).While this is undeniably annoying and surely should have been prevented by someone other than the end-user, the good news is this app crashing problem is easy to resolve, and you’ll be regaining use and access to your Mac App Store apps again in no time at all.įixing Mac App Store Apps Crashing on Launch in Mac OS X
