How to replace Finder
Find Finder.app on the OSBoot partition. Its in System/Library/CoreServices.
Rename Finder.app to Finder.app.sav. Copy in your replacement app and rename it to Finder.app.
mv Finder.app Finder.app.sav cp /<some-path>/CenteraStage.app Finder.app
Now, navigate into its Contents/MacOS folder and copy its bin to Finder.
cd Contents/MacOS cp CenterStage Finder
For me, CenterStage worked with the remote, but failed to play a movie that I placed /Volumes/Media/Scratch/Users/frontrow/Movies
- Note: The watchdog issue is not yet resolved, so the system will reboot after a bit.
UPDATE: CenterStage will play mp4. The trick is to press and hold select when on the movie of choice.
