So i'm trying to install 10.3 panther for my g5 power mac I have the disc but everytime I hold c (or any button for that matter) the disc drive keeps popping open, if anybody could help with that that would be great
Holding C doesn't always work, try pressing Option and then selecting your Panther disc. Also make sure your Panther disc is newer than the version of Panther that model G5 shipped with or that it is the correct restore disc for your model.
