I just did a fresh install of high Sierra on a Mac OS Extended (Journaled) formatted drive. I read that High Sierra converts the drive to APFS format instead of Mac OS Extended (Journaled). However, when I check the format of my hard drive, it shows Mac OS Extended (Journaled), which I thought was weird.
1) Why is this?
2) How do I get it to be APFS?
3) Should I be concerned about errors?
MacBook Air, macOS High Sierra (10.13.5)
Try rebooting into Recovery Mode (holding Command + R when pressing the power button to turn on the mac) and click on Utilities > Disk Utility. From there, click on the SSD and then try converting again. Take note that once converted, you wont be able to go back to Journaled without reformatting the SSD.
Well, that might indicate there is something wrong with the drive or the format.
In Disk Utility, if you select the disk and click the Info button, what does it say for type of drive (solid state Yes/No). There are SSDs that don't seem to be recognized as SSDs.
Maybe your drive is a HDD instead of a SSD.
How to choose between APFS and Mac OS Extended when formatting a disk for Mac - Apple Support
1) Why is this?
Because it only applies to SSDs, not mechanical HDs. We can't guess what you have, you didn't supply that information.
1) It's a SSD drive
2) OS 10.13.5 (High Sierra) was installed to the drive when it was external
3) External drive was then installed internally
4) When I go to Disk Utility looking to convert to APFS, the option is greyed out (disabled)
Do I need to erase drive, format it to APDS, and reinstall my operating system or is there an easier way to convert the Extended (Jourmal) format to APFS?
When I unmount the internal drive, I can then see "Convert to APFS" and I click on it. When I do the convert fails.
"Converting HFS Volume to an APFS Container which will export one APFS Volume
The target is the Journaled HFS+ volume “Macintosh HD” backed by the GPT partition disk0s2
The target is a macOS system disk
Exiting conversion operations with error code -69546
The operation couldn’t be completed. (com.apple.DiskManagement error -69546.)
Operation failed…"
I rebooted on an external drive and tried to convert using Disk Utility, which has convert to APFS greyed out.
And, if it is a HDD (spinning, mechanical), then you shouldn't convert it to APFS.
