Hi. I'm new here, and for the first thread I bring something real challenging. My iMac are running a Panther that is really out of date. Nobody support it anymore. Minimum system today to work is Tiger. So I dicided to install it. I caught the CD version and try to run by USB external CD drive, since internal doest work anymore. As expected, Tiger says "cannot be installed on this machine". So I get XPostFacto4 to force it. But at the manual, says that is not advisible to install over the main system at the first volume. The other volume is not bootable for some mysterious reason. I got to format it at the mac os 9, I got to boot by external drive to do it. But iMac dont wanna boot by external CD drive, and it got no FireWire port. So I put the HD on an external case and plug it at my MacMini to install there. But Tiger does not run under Intel machines, neither OS 9. I try to install NetBoot9 in MacMini (Leopard) to boot iMac from network, but there was an installation error - may it requires OS server. Only sharing volumes or the CD drive is not enought, iMac does not detect it when booting. I'm out of ideas... do you got some? Than you for reading my long story!
