I update my phone yearly and my Mac about every 3 years so ...
And never, ever had a problem with any Apple product, unlike Windows, etc.
I’m still on xp and hardware just as old. I’ll hold off on upgrading as long as I possibly can.
Yep, my 2007 20” iMac is obsolete. So they say.
Works great, just that they keep upgrading me out of working programs.
Since “upgrading” to 10.6.8:
I can no longer use iTunes to stream music.
Some features in ClarisWorks no longer work.
My pcb layout program runs a little slower when I make the Gerber files.
