icloud photos - formatting error

New iMac being setup. Opened photos and went to turn on iCloud Photos and getting this error:

"iCloud Photos is only available on macOS Standard, macOS Extended and APFS formatted volumes."

To check the format of a volume, select the volume in the Finder and choose Get Info from the File menu. The type of volume appears in the Format field.


This is a new 21" iMac with Fusion drive. It is formatted as APFS. Unsure of why I am getting this error and cannot turn on the cloud photo sharing.

iMac, iOS 12

OK, I just got off the phone with Apple Support and it was much easier than it seems.


First, shut down. Then reboot, and then immediately hold the Command+R, until you see the progress bar, then release.


Then, you should get a screen that has 4 choices - choose the bottom one - Disk Utility.


Select your HD on left and run "First Aid" (first button in center menu). It should take a few minutes to run.


Once complete, restart from apple menu, and sign in as normal. Your iCloud Photos should be working.

Interesting . . . tried it a second time and it did solve the problem. The first time First Aid ran it said in the details that it was examining 4 snapshots of metadata. The second time it ran it said it was examining 8 snapshots. No idea what changed from the first to the second but I can confirm that the system has restarted a number of times now and the Photos APFS problem has not returned.


BTW, my system is an iMac21" which was converted to APFS by the Mojave upgrade.

Same problem here. Temporarily fixed using Disk Utilites but it came back weeks later.No reboot during this time. Photos just decided stop working by itself sometime.


My system is iMac 2017 with 1T SSD internal drive so it’s completely irrelavent to FusionDrive issue. Simply a bug in either APFS or iCloud.


Trying to fix again with Disk Utilites and see whether and when it will come back again.

While the "First Aid" helps, somebody should clearly state that there is an error in MacOS which causes it to falsely assume that the disk in use is not an internal disk.


From what I observed, this problem is caused by connecting another server via afp and then at another time not being connected to this server. Maybe OSX is puzzled with numbering the disks or whatever. Apple, your turn to fix this.
