Daryl66 (& Kimmer):
I had more than a dollop of apprehension (not as young as I once was
) but when I received Leopard (installed) on a new MB-Pro, it gave me a real chance to break-myself-in with a protected environment, so to speak. It was/is delightful. Truly delightful.
So, about a month ago, I then got round to installing 10.5.5 on my iMac/Intel. I, too, was worried about that out-of-date compatibility roster I saw here, but since I only observed FileMaker Pro therein – from among my long-term favorite apps – I just, well, did it . . . concluding that my MB-Pro experience and the millions who were waaaaay ahead of me (in line) seemed to be plenty happy. The rosters from
Paddy, Mayo and
AirBusDriver are probably as comprehensive (and
practical) as you'll ever find.
My advice: Don't tarry. You'll conclude, I'll wager, that it's the best move you've made with any Mac you’ve ever owned. Leopard is simply amazing. If I can do it, anyone can.
FWIW, I have now completely retired "The Mozillas" for Mail and Safari. Now if someone would only resurrect WordPerfect for the Mac!
