MAL Updater OS X 2.3.5 Beta 3 has been released for registered users on the beta update channel. This beta changes how detection is handled so it will only detect if the player application is running. It’s now possible to create dedicated rules for MPlayer OSX Extended, MPlayerX and SMPlayer with mplayer2 support. Also, MAL Updater OS X will now reset if you remove an account.
You can download the beta here. You must have a donation license or app store version registered before you can use the beta. Use the most recent stable build to register your copy of MAL Updater OS X today.
