I have a bootcamped Mac, and I want to share my SteamApps folder between the two operating systems, since the bulk of the storage is in game assets.
I've tried using an exFAT partition, but OSX has a bug that reports it as case sensitive when it isn't, so Steam refuses to run on it. Fat32 is no good due to the 4gb limit.
I would rather not have to wrangle some sort of 3rd party ntfs / hfs driver for either side. Thats a last resort option.
Surely others out there want to do this and someone has succeeded?
