Can one Leopard hard disk boot both PowerPC and Intel based Macs?
We have successfully booted both a Power Mac G5/1.8 uniprocessor system and a 15″ MacBook Pro LED Display model from one Leopard hard drive. Leopard finally delivered the universal, cross-platform boot capability we’ve been craving. One previous problem was that we needed separate versions of Tiger for Intel and PowerPC Macs. Leopard resolved this issue. The second problem was that Intel and PowerPC Macs needed the hard disk formatted in contrary ways. Intel Macs insisted on configuring boot drives (via Disk Utility) for “GPT” (GUID Partition Table), but virtually all PowerPC Macs have to boot off hard drives formatted for APM (“Apple Partition Map”) instead. It’s a whole-drive option – all partitions (“volumes”) on the hard drive share the same partition table. We can now boot both PowerPC and Intel Macs from one, universal Leopard system installed on an APM-formatted hard drive. On the downside, Intel Macs may have problems updating firmware or running Boot Camp from an APM hard driv
