When the update to 10.4.3 came, my Front Row left, as the update somehow managed to cripple my (illegal as we may call it) FrontRow install
Now there’s Front Row Enable which is an App that now only simplifies the process of installing Front Row to a great extend, but also seems to be able to activate it again on 10.4.3 Macs
I didn’t try it yet, but I’ll do so today, and hope that it’ll enable me to enjoy the joys of FrontRow again.
