I just got OS X running on my 7500/Sonnet G3 upgrade last weekend. I used Ryan
Rempel's installer which you can download from OWC's website.
http://eshop.macsales.com/OSXCenter/
Sonnet also has an installer for their cards, but you have to pay for it. Rempel's is
free.
The installation procedure itself isn't too difficult, although I did have some
problems with errors (possibly my CDROM drive going south). OS X runs OK on my
machine, although it feels rather slow, especially screen updates. Classic apps run
much slower in OS X than in OS 9. Native applications of course are faster. I compared
Bryce 5 (which is OS X native) on both OSs. My impression is that it seems a little
quicker under OS 9, but not by much. OS X is stable though. So far I have not had to
reboot once.
The main problem upgrading an old-world Mac for OS X is with PCI video cards. In most
cases you will not be able to use a PCI card at all, only the onboard video. I am able
to run OS X with my IX Micro Ultimate Rez card, but only if I have a monitor or VGA
adapter plugged into the onboard video connector. Without it, the system crashes
during bootup. I also tried a Voodoo 5 5500. That crashed the system during boot no
matter what was plugged into the onboard video.
Another potential problem is OS upgrades. I am sure that we will have to wait for
Sonnet or Ryan Rempel to upgrade their installer programs for 10.1 when it comes out
next month.
I like a lot of what I see in OS X (I am a UNIX type). I do agree that 10.0 is not
really a finished product. It can only get better. However I am seriously thinking
about biting the bullet and upgrading to a supported machine (maybe a B & W).
If you are willing to do a little more work installing, and you are happy using the
video port on your Mac, you might want to try OS X. If you need better video than what
is built in, the IX Micro card will work (with a monitor or adapter on the onboard
port). IX Micro is out of business, but (last time I checked) OWC still has Ultimate
Rez cards for $39.95. They are nice 2D cards (but poor for 3D).
Before you decide to install, look at Ryan Rempel's page. It may or my not be worth
the trouble. As for me, I know that I will be using OS X in the future. But right now
I think that for day to day work on the 7500, OS 9.1 is more practical.
