PT Prefs is a utility program for Mac OSX which can delete / backup / restore various preference and support files - Pro Tools preference trashing in other words! It doesn't delete any essential system files, they are all just settings which at worst can be manually re-entered. Sometimes Pro Tools benefits from having these files cleared out (after a crash/blackout etc) - Pro Tools remakes them with default settings when it is run next. Therefore if you are unsure which options to check it is safe to check them all, in fact if you are running this software due to a problem rather than as a matter of course I would recommend trashing
all preferences, it's more likely to solve the problem.
It's freeware, anyone is welcome to use it - but, and I cannot emphasise this enough
at their own risk. It is not extensively tested on multiple OSX versions. Always have your system backed up. I will endeavour to fix the software if any problems arise though this software is provided free and not under any explicit or implied contract of service or warranty so treat it as such.
Any problems/queries/suggestions, keep them to this thread.
