Recently, I've been wanting to put Tiger on my Power Mac and test it out. Maybe even switch from Leopard and start using Tiger as my main OS. But the only Tiger discs I have are for my iBook G4. I have a trick that involves target disk mode that will allow me to install Tiger on the Power Mac (if you don't know what it is, feel free to ask). Here's my question: Is the iBook G4 version of Tiger optimized in any way? Will I need to modify anything to get full performance on my Power Mac? Thanks for any help.
