Whenever I go to change the location of the cache, or even its size, the value immediately resets back the next time I open the preferences panel. Same happens if I try to do this in ACR 6.1. The location that I want to point it at is perfectly valid, on my local drive, and I have all permissions for it.
Since Adobe apps are slightly retarded and don't follow symlinks, an attempt to sneak in a different location under a symlink ended up as expected in a crash.
Any ideas how to change the ACR cache path, or why it would be failing? No messages in the Console. OSX 10.6.4, Nehalem MacPro.
Symbolic links work fine - see this thread:
Apps have no choice - they aren't even aware they are links, the os sends the end result to the app.
No, links don't really work with any Adobe apps, at least not on OSX. Just try to create a symlink to any of the Camera Raw settings folders (lens profiles, camera profiles - so that they are all the same on all my computers) - no dice. I write OSX software for a living and know my way with symlinks - not sure what Adobe is doing but they don't work.
But that's not the issue here - my question is why I can't change the cache directory the "normal, pedestrian way" (your average user won't know anything about symlinks).
I have now tried that and that didn't work, either. I could change Bridge's cache, but not ACR's.
Does anyone know in which preferences file the ACR cache is saved? It's not in the Lightroom prefs file. I could try modifying the prefs file using PropertyListEditor...
I wonder if the volume you are going to is unexpected. All sorts of apps have trouble with case-sensitive versions of the various filesystems you can make on OS X (as opposed to case-preserving/case-aware.)
