OS X on OS 9 Macs

If you have an older Mac running OS 9 and earlier, it might complain if you attempt to upgrade it to OS X. Certain older machines have genuine issues preventing them from running OS X without hardware modifications–but for more recent Macs, especially G4s, it’s more likely that Apple just has an incentive to get you moving on to new hardware.

Low End Mac explains the various issues involved in detail. They also sell RAM, video cards, and other parts for older Macs. A summary:

1. OS X 10.5 Leopard on a G4
It should install without trouble on machines 867MHz and over. Otherwise, you’ll need a utility called LeopardAssist to force an install. If LeopardAssist also fails, you might have to use an earlier version of OS X.

2. OS X 10.4 Tiger on a G4
It should install without trouble.

3. OS X 10.3 Panther and earlier on a G3
G3s can manage at least OS X 10.2 Jaguar, and some can run Panther; it varies depending on the model. (The newer G3s in blue cases will do better than the older ones in beige.) To install, use a utility called XPostFacto.

4. OS X on a pre-G3 Mac
You can consult this compatibility list for installing OS X on pre-G3 systems…but that might be more trouble than it’s worth.

Remember that, in all cases, you may need to get ahold of an external DVD drive if your older Mac can’t read DVDs. And if your install disc was bundled with an Intel Mac, you can’t use it to install on a PPC Mac.

Finally, if you don’t know what kind of OS 9 Mac you’ve got, use the System Profiler:

Flash and Function Keys

Unusually for a modern application, Flash demands that you learn to use the function keys at the top of your keyboard. (On a Mac, these rarely-used keys are typically reserved for changing screen brightness, sound volume, and the like. You can change this default setting in the System Preferences.) The essential commands are:

( Create )
F7: make a new empty frame.
F6: duplicate the current frame.
F5: extend the current frame.

( Preserve )
F8: convert the current selection into a Symbol.
Command – F8 (Mac) or Control – F8 (PC): make a new empty Symbol.

( Destroy )
Shift – F5: delete the current frame, and close the gap on the timeline.
Shift – F6: delete the current frame, and leave the rest of the timeline in place.
