I am trying to install Mac OS X from the CD to a flash drive, as I do not have a spare hard drive and the internal one is missing. I have formatted the flash drive to the Apple Partition Map and the drive is formatted to Mac OS extended. What do I need to do to get Mac OS installed on this USB stick?
This series of Mac can’t boot from the USB port ;-{ Your options are limited! You can boot up via a bootable optical disk (CD or DVD) or a FireWire 400 external drive You’ll need to dig around for replacement SATA I (1.5 Gb/s) drive. Most drives today are fixed speed SATA III (6.0 Gb/s) which won’t work here. Some drives offer auto sense technology like Samsung SSD 870 EVO SSD note the interface line lists support! Make sure the drive you get spec sheet lists is like this one, if it doesn’t don’t buy it!
for slightly different purposes this article https://www.chanhvuong.com/1420/clone-ma… suggests instead “check that the “Partition Map Scheme” is set to “GUID Partition Table” (which means it is Mac OS X bootable).”
