We have new CS6 via creative cloud. However none of our users can save photoshop files back to our mac server (10.07)
All other CS6 products will do this fine its just Photoshop that will not.
We have tried running updates and this has not worked?, this bust be a bug in Adobe - any one know how to fix this.
(its not a sever issue as all users with all other applications are saving back fine - its just photoshop)
Which OS version?
MacOS has a lot of bugs with fileservers, and we've added error checking in Photoshop to catch a lot of those errors (instead of silently losing your files).
Apple is fixing some of the bugs, and we're actively trying to work around the rest.
But server configutation issues can also cause problems (permissions, shared user id's, etc.).
I have the same issue. Photoshop CS6 running on two 3,1 Mac Pros with 10.7.5 and 10.8 wont save to our 10.8.2 Server, whilst PS on 10.6.8 seems fine.
Weirdly, we have a 5,1 Mac Pro running 10.7.5 which saves just fine too.
We receive an error messag that states files cant be saved as PS sees the file as locked or lacking the necessary permissions or that the file is already open.
Previous versions of PS can save to our server with no problems, as can the other apps in the Creative Cloud suite.
Disabling 'save image previews' and 'save in background' functions has not been successful in working around the problem.
Previous versions didn't have the same error checking - as we find new problems with OS filesystem code, we add new error checking to catch those problems. And 10.7 introduced several new filesystem bugs related to fileservers. 10.8 added a few more, but has already fixed one of them.
Chris didn't say it, but Adobe does not support your trying to write files directly from Photoshop to your server. No way, no how.
The pertinent paragraph:
If you use Photoshop CS6, CS5, or CS4 without Creative Suite, Technical Support strongly recommends working in Photoshop directly on the local hard disk. To prevent data loss, save files to your hard disk first. Then transfer them to the network or removable drive in the Finder or in Windows Explorer. To retrieve files, copy them in the Finder or in Windows Explorer from the network or removable drive to your hard disk. You can then open the files in Photoshop. This workflow avoids problems that occur when network system setups or removable media device drivers are incompatible with the operating system or Photoshop.
As you can see, they suggest copying the file to your local system, saving locally, then using the OS to copy it back. This also has the advantage that if you do something unexpected to a file the original is still there on the server.
