Hi,
I have a 2017 Touch Bar MacBook Pro and I had a problem installing an app from the internet. It would bounce on the dock and then disappear and nothing happened. So I through I would try booting into safe mode, by pressing shift when my Mac is starting. However my Mac doesn't boot into safe mode. It will full load the bar on startup and then just stay with the apple logo and a completed bar. Starting the Mac normally work.

Anyone have any ideas on how to fix this?
Thanks

So I managed to get into safe mode. The app did not install, and apparently there are a lot of errors on my drive

I get the errors of:

snapshot fsroot tree corruptions are not repaired they will go away when the snapshot are deleted.
I have no idea what that means and I can't find anything on google

That's referring to APFS snapshotting which is "sort of" a backup feature.
You can use diskutil apfs list to show your APFS volumes, and
diskutil apfs listSnapshots (identifier) to get a list of snapshots
After that, the deleteSnapshot command can remove it.

This should be unrelated to any issue however. It may point towards other drive failures, but by itself a snapshot error should not cause system instability, just inaccessible local backups
