[QUOTE="monk64, post: 1808901, member: 360642"] I'm running up-to-date macOS Mojave on a late 2015 iMac with the 3TB fusion. Was trying to set it up for Bootcamp (yes, this model supports it), and am seeing errors when it does the disk check: [CODE]The volume Macintosh HD was formatted by hfs_convert (945.200.129) and last modified by apfs_kext (945.230.6). Checking the object map. Checking the snapshot metadata tree. Checking the snapshot metadata. Checking snapshot 1 of 5. warning: total_segments reached warning: object (oid 0x4000114977698): Unable to mark physical extent range (0x4000114977698 + 114) allocated for space verification error: btn:1: invalid key order (1) oid 462294 / oxid 0 Snapshot is invalid. The volume /dev/rdisk2s1 could not be verified completely. Operation successful. [/CODE] Get the exact same messages when I boot to single user mode (CMD-S) and run fsck_apfs manually there, or when I run disk utility in the CMD-R recovery mode. I fooled around with some tmutil commands to delete all local snapshots - no difference. Also ran a TM backup to completion - no errors, but also didn't change the above. CCC also reported a couple errors, though after deleting a file that it was stuck on, CCC ran successfully last night. I'm wondering if I need to nuke the system and restore from TM? Seems to me that APFS is not quite baked :-( If I do nuke, can you still use HFS+ on Mojave? [/QUOTE]
