And about to orphan my 800 MHz iMac, though maybe XPostFacto will come

to abort on install, as with Aperture, or if it will install and run
slowly. My guess is the former. Slow systems are a bad advertisement for Macs.

The reports I've seen, it will abort on install if the machine is not officially supported. However, I have also seen reports that people were able to bypass it and get it to install and run on things as low as 400 MHz G3s, but they had problems (such as certain applications would fail to run).

I'd suspect that XPostFacto will come to the rescue at least for any machines that are borderline supported, such as the 800 MHz iMacs and eMacs. However, I don't know why Apple decided on the 867 MHz mark other than it sets the bar at a specific PowerMac G4 model, so it may be related to something else that was introduced with that model, such as a specific video card, that may not be present on anything earlier.

In other words, even if/when XPostFacto allows installation, there may still be other reasons for 10.5 to fail or not work 100% right.
