Funky frank Posted December 1, 2017 Share Posted December 1, 2017 Only to be 100% sure here, if I start the macOS 10.13.1 updater with this command: /Applications/"Install macOS High Sierra.app"/Contents/Resources/startosinstall --converttoapfs NO --agreetolicense It still will update to High Sierra WITHOUT APFS conversion? And I do not need to choose any extra option while installation? Is this outdated now? Thanks in advance! P.S: I have TRIM enabled currently on my 10.12.6 evo850. Will it cause any problems?

alaskantraveler Posted December 2, 2017 Share Posted December 2, 2017 Depends. Are you updating on a SSD? Then, probably. If you are updating a Sata drive that is an old fashioned hard-drive or one of those hybrid types, they won't change over to apfs but will stay with the original file system, although I believe if you say yes instead of no to apfs they will be converted.

RSN Posted December 2, 2017 Share Posted December 2, 2017 http://hackintosher.com/guides/how-to-opt-out-of-apfs-in-high-sierra/ I didn't do exactly what is said here since I have another SSD that I can boot from and then just changed the entry in the file of the destination install volume via terminal.

Funky frank Posted December 4, 2017 Author Share Posted December 4, 2017 Well there are now some recovery tools available that are capable of accessing APFS volumes. I guess I will then let the installer convert to APFS. At least I have another Mac with 10.13.1, so I could access the hdd in case of a system fail. Still APFS does not give me a secure feeling, could be irrational though. Also Macdrive 10 now supports APFS, so you would have access to the volumes from Windows side.
