The oems force you to choose between only fw or only usb! This is a great workaround for a universal system until apple fixes this in leopard (and so many other tiger gotchas).īut one note of frustration regarding the boot drive - unless one is willing to have a bulky 3.5" device to lug around, a 'mobile' a formfactor is the most practical approach.īut for some silly reason, none of the 'mobile' devices (2.5" winchester & slim dvd burners) are not avail with combo (usb/fw) interfaces.
#CREATE A MAC OS X STARTUP DISK UPDATE#
This hint is only intended for Administrators, since update mechanisms may fail, and Apple could change something at any time such that this Universal binary image may not work anymore! That's it a single universally bootable OS X system.Ĭaution: I do not recommend using this image for production or mass deployment. I again chose MacOSX UNIVERSAL as the startup volume, and found that the PowerPC iMac booted just fine. After a few seconds, I got a screen where I could choose which system to boot from. I then connected the external FireWire Disk to a PowerPC iMac, started it up, and pressed the Option key immediately.The MacOSX UNIVERSAL partition booted the Intel iMac without any problems. I then selected the MacOSX UNIVERSAL partition as the startup volume in the Startup Disk pane in System Preferences, and restarted.After that, I cloned the MacOSX INTEL partition on top of the files from the PowerPC partition on the MacOSX UNIVERSAL partition, also in file copy mode.I then cloned the MacOSX PPC partition to the MacOSX UNIVERSAL partition on the FireWire Disk, using CarbonCop圜loner (in file copy mode).
I booted an Intel iMac, and connect my external FireWire disk. I tried it and it worked! The procedure was very easy, since I had already prepared an external FireWire disk with four partitions as described above. Other system files, specific to the PowerPC platform, would be left alone. That way, all the PowerPC-only kext files, etc., would be replaced with Universal binary files. Is it possible? Yes it is!Īfter I read this very interesting article from Andrew Mortenson, wherein he describes how he succeeded in creating a bootable Universal binary Mac OS X System with Radmind, I figured that there could maybe be an easier way to accomplish this.īased on the assumption that all the important system parts are already Universal binary, and that the Intel 10.4.5 System is only missing some hardware-specific files for the PowerPC platform, one could maybe clone OS X Intel on top of OS X PowerPC. Now we only need a way to combine the two systems into one. This can be done such that you can actually boot from both partitions, as shown by Jonathan Rentzsch and by this hint posted here previously. I then copied a G5 iMac's OS X 10.4.5 System onto the MacOSX PPC partition, and an Intel Mac's OS X 10.4.5 System onto its appropriate MacOSX INTEL partition. I started by reformatting an external FireWire drive on an iMac G5, and created four partitions on it: My goal was to try to create a Universal binary Mac OS X System in an easy way, so other System Administrators or interested people can also recreate it. Apple is probably releasing a Universal binary Mac OS X 10.5, but can we wait? No! Ideal would be an OS X system which is Universal, and therefore able to boot both Intel and PowerPC Macs. Without a Universal binary, Mac OS X 10.4 System Administrators like myself must effectively double their responsibilities and maintain two operating systems, one for each platform.
