I can't remember if this is some sort of limit by the system or Java, but it would be nice to have consistency for using Copy, Select All and Paste on OS X. If possible, this could be resolved by changing Ctrl+V, Ctrl+X, Ctrl+A and Ctrl+C (Paste, Cut, Select All and Copy) to use Cmd / Command over Control when using OS X. (This applies in-game and not to the launcher, of course.) Perhaps both controls could be used in case any users want to keep their Ctrl usage.

Again, not sure if fixable.
