How to Upgrade to APFS if Not Done in macOS High Sierra Installer (The Mac Observer) 03. Realised, macOS drive wasn’t changed to APSF – found this solution how to convert it manually from HFS+: Just installed #macOS #HighSierra with excitement, but after logging in I’m just sitting here like... “what exactly did they change again?” /oLdIXEAEoF Successfully downloaded and installed macOS High Sierra Beta (17A291M) on my external SSD drive Redone another 2 x First Aid with Disk Utility – once one the volume’s container (AppleAPFSMedia) and once on the volume itself again (macOS). In Recovery Mode tried $ fsck_apfs -qn /dev/disk3s1įrom Utilities > Terminal with repeating result: drive is still OK.

However in my scenario it is definitely not related to an encrypted external drive, because I didn’t have it encrypted previously. Did some online research regarding the “mount attempt error -69842” and looks like this issue has come up for others in various constellations as well: Redone another First Aid with Disk Utility – repeating result: drive is still OK. Tried to reformat the whole volume structure as APFS. Formatted the external SSD volume & tried to reformat it directly as APFS. Preparing to backup the data onto another drive, so the external SSD can be reformatted with APFS and I can install High Sierra Beta from scratch. In the meantime, Apple also confirmed the issue as a bug, by referencing it as duplicate to the bug report #32984876Īll previous steps and approaches I tried to resolve the APFS issue J01.
