For some reason my mac always resets my 'open with' preferences if I restart my computer. So for instance, even if I go through the usual route of selecting a program as the default player (select file/get info/open with/change all), as soon as I restart my mac it will always revert back to the default players and not the newly selected one. Is there a work around? A setting in OSX which im missing? Or perhaps a third party app which can handle this? Any advice appreciated!
