Hello. Ive purchased a used emac from a friend. 800Mhz, 256MB, 60GB HD, SuperDrive. Nice little machine for the kids. It has OSX 10.2 (Jaguar). I would like to upgrade it to Tiger. (wont support Leopard). My plan was to take my iBook license of Tiger, install it on the eMac, and then purchase Leopard license for my iBook. Would like to know if this is legit. To see if this was viable, I tried to install Tiger on the eMac with the install DVD that came with my iBook. It starts up the install process, and the says that it cannot be installed on this machine. So, any help in this matter appreciated. Im not trying to circumvent anything. If possible to buy leopard for iBook and use its existing license on eMac that would be great. Help on why it wont install would be appreciated. If this is not viable, not a biggie, I will get whatever I need. Thanks in advance for any input.
