Question

Case-Sensitive Error (Error Code: P22) on a Non-Case-Sensitive Volume

Running OS 10.14.6 on a 2018 Macbook Pro. 

 

I downloaded Creative Cloud and tried to install it. My drive had been formatted to APFS (Case-Sensitive). Obviously, Adobe doesn't support Case-Sensitive Drives, and I learned there was only one thing to do: reformat my drive. So I used Time Machine and my external drive to backup my data, wiped my drive, reformatted it to be APFS rather than APFS (Case-Sensitive), and restored my computer from the Time Machine Backup. But when I tried to install Creative Cloud, it's still giving me the Error Code P22: can't install on a case-sensitive drive. 

 

Adobe Tech Support has been useless. I'm guessing there's some sort of issue in which the Creative Cloud installer thinks the drive is still case-sensitive, because I restored from a Time Machine Backup. Can anyone help? Or is this computer simply destined to not run Photoshop?

One thought: have you rechecked whether it is still as you formatted it? The restore might have undone it...

    When I open Disc Utility, it shows my drive format to be standard APFS, not APFS case-sensitive.

     

    But I agree with you - I think that restoring from the case-sensitive back-up is one of the reasons it isn't working. But I don't know the solution

    Steviebwolf, I have found Error P22 to be accurate in the past.  You stated you restored from a Time Machine backup.  Did you do a full restore or did you only restore the documents and settings?

     

    Did you utilize the process listed in https://support.apple.com/en-us/HT208496 to format the drive to APFS and not APFS (Case-sensitive)?
