Well, my PMG5 originally came with a version of tiger 10.4.(something). The retail disk has 10.4. However when I try to install tiger with the retail disk, it refuses to boot from the disk and goes into a kernel panic. This is because the disk has 10.4, which is earlier than the version of tiger my G5 came with, which was 10.4.something. I can't find the original restore disks, so I don't know what to do, this is my last resort. Does anyone know where to get a copy of tiger that was released after when my Late 2005 PMG5 came out? Please don't respond telling me to get Leopard, I already have it but want to dual boot my G5 to run Tiger and Leopard. Also to be honest I don't care much about piracy etc so I would greatly appreciate it is someone could provide me with a copy of tiger that I would be able to install on my G5? Thanks in advance!
