Cant' update and/or reinstall Photoshop on MacOS Sequoia

Hi, I've a strange problem with PS update... Both update to 26.6.1 and install of PS Beta 26.8 fails with this error message: 

 

Exit Code: 181
-------------------------------------- Summary --------------------------------------
 - 1 fatal error(s), 1 error(s), 0 warnings(s) 

FATAL: Error occurred in install product workflow with error code 181 error message 
ERROR: Can't install to a case sensitive drive
-------------------------------------------------------------------------------------

 

I have installed all Adobe ecosystem in /Applications folder, that in MacOS is a link to /System/Volumes/Data, and this volume IS NOT a case sensitive drive! (see attachment)

I've had no problems updating LR, LrC, Camera raw and so on, that are installed in the same folder.

I've also tried to completely uninstall PS Beta and now I can't reinstall it.

 

Any ideas? Thanks

 

Correct answer kglad

As I wrote above, it's /Applications, the standard one on a Mac

And, BTW, this is the path on which the current version of PS is actually installed (and working without a single problem)

Adobe support closed my issue with "After reviewing the error logs, we identified that the issue is related to the drive being case-sensitive, which is incompatible with Adobe installations." 

Totally wrong.

 

 


uninstall every cc app (including preferences for the problematic app) per https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html

then uninstall the cc desktop app, using the correct uninstaller per https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-messaging

clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html

check for, and if available, update your os

restart your computer (don't skip this)

reinstall the cc desktop app using the "alternative download links" at the bottom of the page at https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html

use the desktop app to install your cc programs/trials>

>this volume IS NOT a case sensitive drive! 

 

Something about that drive/volume is being mis-identified by the installer... I'm on Windows, so I don't know why

    Adobe Support is stuck repeating that the drive IS case sensitive, but this is wrong... I'm (was) an Unix system engineer for 40+ years, so I think I do know what I see... 

    A simple test:

     

    $ cd /Applications
$ touch Test
$ rm test
$ cd /Volumes/Extra/Applications (A CASE SENSITIVE DISK!!)
$ touch Test
$ rm test
rm: test: No such file or directory

     

    That's so simple...

    are you using a case sensitive hard drive?

    No, of course not.
