When I try to install the upgrade to Catalina, I get the message above for my boot drive. I am currently running 10.14.5 (Mojave) and the drive is formatted as Mac OS Extended (Journaled). This is REALLY strange! And after reading some of the message today, maybe I'm better off not getting the upgrade to work. Any thought on what to do about this? Thanks!!
You may be able to boot into Recovery Mode and convert the volume to APFS.
You should make sure to have good verified working backups before attempting the procedure. If something goes wrong you will most likely need to erase the drive and either perform a clean reinstall of macOS or a restore from a backup.
The real question, before I venture into what appears to be at least 4 hours of aggravations, is: is anything in Catalina worth it?
thank you for sharing, it explains a lot ...I installed a crucial ssd half a year ago in my mac mini late 2012
THIS was super helpful. Thanks!
If you need to convert to APFS run your Mac in recovery mode and use disk utility to convert your drive. In disk utility unmount drive first and then convert option becomes available.
Exactly. Then the best solution is to clone the drive after another drive that has Catalina, and it will work :P :P ?
Hi there, How to solve this issue ?I created a partition and formatted in APFS, but it still don't work, please help.
I really want to upgrade to the latest version of mac os
🤜🏼 I'm also a linux guy hence the rsync but otherwise yes, think this is the most fail-safe method.
Thanks to everyone for comments. After reading your comments I'm going to wait for an Apple fix as well.
I have the same problem. And in the disk utility in the recovery mode, there is no "convert to apfs" option. That's strange. please fix this problem, Apple.
Hi,
I had success by calling Apple Support and they walked me through the back-up and reformatting. Took about 15 minutes and that took care of the issue. Another great job by Apple Support!
This volume is not formatted as APFS
