Updating imac g3

Here are the steps: Another option is to use an external Fire Wire enclosure for formatting/partitioning the receiver drive and cloning your disk image to it.

Using this process, you can create a bootable OS X drive for a tray-loading i Mac, beige G3, or Wall Street Power Book without ever touching XPost Facto.

The most important step in upgrading tray-loading i Macs, Blue & White G3 Power Macs (especially the Blue & White G3), and a few other Macs of that period is making sure you update the firmware before you install any software updates or new versions of the Mac OS.

Drives that you may want to replace "just because" even if they still work.

Older G3 Macs can support drives as big as 128 GB with no trouble; there's no practical way to overcome this 128 GB limit (the Intech Speed Tools mentioned in our article on big hard drives in older Macs costs , more than these old i Macs are worth).

(You can't boot from a CD to do a firmware update; you have to boot from a hard drive.) Be sure the firmware update has taken before upgrading your Mac OS installation, as you can otherwise end up with a Mac that won't boot with the OS you've just installed.

Another tip from Bill: If you do end up with an unbootable tray-loading i Mac and have access to another i Mac that's working just fine with the version of the Mac OS you installed, swap out the little daughtercard CPU modules.What Bill likes to do is scrounge up smaller, generally faster replacement hard drives, usually in the 10-15 GB range, and put those in the old tray-loading i Macs.
