Report: Apple’s Mac OS X Leopard minimum requirement: 867 MHz G4

“Just weeks ahead of its public launch, Apple Inc. has updated the minimum system requirements for its next-generation Leopard operating system to exclude 800MHz PowerPC-based Macs,” Prince McLean reports for AppleInsider.

Apple “had long stated in developer documentation that the software would require ‘an Intel processor or a PowerPC G4 (800MHz or faster) or G5 processor,'” McLean reports.

But, “engineers for the company recently determined that Leopard installs on 800MHz PowerPC G4 systems ran ‘too slow,'” McLean reports. “Leopard will now require Macs with ‘an Intel processor or a PowerPC G4 (867 MHz or faster) or G5 processor.'”

MacDailyNews Note: It’s not that Leopard won’t run on lower-spec’ed Macs, just that Apple won’t be recommending it (based on the fact that our still-working iMac DV 400 MHZ G3 with 192MB of RAM is currently sitting in a corner happily running Mac OS X 10.4.10 Tiger).


  1. Considering that this keeps a lot of Mac’s running the latest and greatest it’s good news. Now compared to the Window’s upgrade path that says it’s time to update hardware to keep our partners happy, it really shows the difference in company visions.

  2. Then my Dual-867 PowerMac should have no problem. But my trusty Pismo Powerbook (500 MHz, 512 MB RAM) will continue to run Tiger.

    Funny, I’m servicing a colleague’s Presario 700Z notebook of the same vintage which has crapped out (failed drive) which struggled to run XP Home! That mine is still usable while hers is basically worthless shows, once again, that Macs have a longer usable life, and thus a lower cost of ownership. Most still don’t get it.

  3. Have any of you heard about the problem that’s popping up about freezing 20″ and 24″ iMacs? I bought a 24″ iMac about a month ago. It worked great until I applied that recent iMac-only update. Now it’s freezing up about 3 or 4 times a day. And I’m not the only one who’s seeing this. Found this message board at Apple’s service site full of people having the same problem:
    It seems to lock up the UI, although the CPU is still running normally. But there is no recovery except to restart the damned machine. This is getting ANNOYING. The growing concensus on the board seems to be that there may be a video card driver issue, but this is all anecdotal. I hope I don’t have to return my brand new machine for service. That would be so . . . Dell.

  4. Well Jim considering Californa laws, you can only sew Apple for OS X able computers that aren’t G3. So once OS X doesn’t work on G4s then you can sew because Apple would have lied about what they said.


    My wallet is feeling warm as it’s well insulated with all THAT CASH from selling MY HOUSE BEFORE THE BUBBLE BURST!!

    hahhaaaaa! the subprime fool already foreclosed!!!

    Bring on the bloated LEPOARD APPLE!!


    So I won’t have to upgrade for 10 years!!!

  6. @raymond from dc: same here – my pismo runs 10.4.10 great. i’ll be upgrading soon, but it’s amazing that a nearly 8-year old laptop can run the current OS X. i very much doubt the same could be said for vista on the k6-2/early pentium iii laptops of 2000. =)
