I know this seems like an beginner / dumb question, since an obvious answer would be:
- Open Disk Utility
- Remove Linux partition
However it seems that it might not be that easy, and that following those steps could actually lead to pretty messed up partition schemes:
- Remove Linux partition on Mac. CoreStorage problems
- OS volume shows as type 'FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF'
- Hardrive will not mount after deleting Linux partition. Can’t boot into Mac OS X
- Remove Ubuntu and grow Mac partition
I am therefore asking this question in hope for a proper, safe way to remove a Linux partition after a dual boot Mac / Linux, without having to fear going to an hex editor to repair your drive or to use the internet recovery and losing all your data.
I'm running High Sierra 10.13.6 and Ubuntu 18.04, without REFind and no swap partition.
