Does anyone have any experience of using an install disc of one machine on another type? Since i bought panther for my iBook that leaves the copy of 10.1.4 i got with my iBook free for use, right? Is it even worth it to put 10.1.4 on a Yosemite tower (350 Mhz, 128MB RAM)? - it would be used by my mother for the internet only. thanks a lot guys, pmd.
