Logic x doesn´t launch in High Sierra.

Let's see, apps that crash every time on launch: Numbers, Pages, Logic, iReal Pro, Pixelmator, Keynote, iMovie, Garageband, Kindle,

Apps that still work: iTunes, Photos, App Store, FaceTime, Calendar, Reminders, Contacts, Time Machine, Spotify, MuseScore

Ok, I just discovered something that might be relevant, although I'm not sure what to do with the information. When I press and hold the ALT key in Launchpad, only the apps that crash get the little x in the top left corner. The other apps just "jiggle", but without the x.

Same problem here. Upgraded to High Sierra, now loads of apps crash on launch every time.

Relatively frustrating, to put it mildly.

it should, Which version are you running?

have you rebooted your Mac completely.?

which other apps are crashing, Apple ones or third party or both?
