I've been having trouble when trying to save Logic 9 files in Yosemite. I tried right-clicking the master folder, selecting "get info" , unlocking it, setting all permissions to read/write/exe for all users, and then applying that to all the contents of that folder. But some files still won't let me save them without manually finding it within finder, and setting the "everyone" setting to read/write/execute. ("everyone is a user which does not appear in the folder properties, only in some file properties) I've tried running "repair disk permissions" but that doesn't seem to bring up any issues. I've got a few user accounts, but all of them are set as having admin privileges, and I'm not working on files which I've created as other admins. Some files WERE created on another mac, though. I've been looking around and note that there is a way using terminal and something called CHMOD to edit all the permissions of a folder. Is this something I could do? I just want my music folder to be completely free to read/write/execute on all current files, and also on all new files I create. I've got an app called "Path Finder" which I have used in the past instead of finder, but I'm trying not to use it now, in case it's messing things up... Any tips?
