I'm trying to work locally on a Mac installation of Craft but keep getting permissions errors with Storage, and so on. I don't get these errors when working locally on Windows using these same files (synced using Dropbox).
Is there a way to fix this without manually changing every file? I've changed the permissions for Storage and Runtime but am now getting Unable to create a cache directory. Even if there is a fix, will I need to repeat it for each project I create on Windows and later work on using the Mac?
