Is anyone running leopard on a g4 MDD single 1.25 processor? I have 1.25 gigs of mem. From the specs it seems like it should work, but I just want to hear of real life usage. I'm on panther and have decided to get an iphone but, thankfully, just saw another post stating you need at least tiger and on ebay used tigers don't appear to be that much cheaper than an new copy of leopard so i thought i'd ask. I did try searching with terms like "leopard running on MDD" and alike , but I didn't see anything that jumped right out. thanks!

I have Leopard on my dual 867 MDD with no issues.

I don't believe Apple ever made a single-processor MDD, so you probably have a Quicksilver. At any rate, Leopard should run okay on it.

Actually, they did make a single proc MDD in 2003. Anyway, I'm sure Leopard has no issue with your MDD.

Leopard runs great on my 1,25GHz single processor MDD, no need to worry at all.

oh, I also have 1,25 GB RAM.

I sit corrected...Apple did make a single-processor MDD. it was actually the FW800 model, but it was a 1.0, not 1.25, according to Apple-History.com.

Actually they made two:

New PowerMacs and 20inch LCD from Apple - Mac Rumors
and
June 2003 Single 1.25GHZ with option for dual 1.25GHZ.

I have a single proc 1.25 MDD and it doesn't have FW800 (there was a model without FW800 that was a single proc). It runs Leopard pretty damn well with full compliment of RAM.

It's this one:

Apple Power Macintosh G4 1.25 (MDD 2003) Specs (Mirrored Drive Doors 2003 - M9145LL/A) @ EveryMac.com

Don't stand up. Keep sitting. Corrected.

Yes, the single 2003 MDD model was aimed to keep a Mac OS 9 bootable Mac, hence the lack of FW800.

AirPort Extreme (802.11g) was missing as well.

I have a Powermac G4 quicksilver single 800 Mhz processor, according to Leopard system requirements im just short of the requirements, am i stuck with 10.4.11 with this G4 or is there a way to run leopard smoothly on this machine?

A friend of me has succesfully installed 10.5 onto a single 733MHz QuickSilver with the help of LeopardAssist, link below:
LeopardAssist - Install Leopard on Sub-867mhz Macs

Not speedy but runs 'OK'.

i have a dual 500 gigabit G4 with 1.25GB that runs Leopard respectably...not a speed demon by any means, but is used every day for small tasks and hosts a few webpages...

They never made a 1.25 GHz Quicksilver

Thanks for the link, i had one more question, being Leopard was not designed for my machine would leopard run slower on my machine that 10.4.11?

angelmb · Mar 24, 2008, 02:12 PM

I don't want to claim slower, speedier… I think two users with the very same set-up could easily disagree on which is faster, cooler and what not. In all honest I had never thought I was going to upgrade to 10.5 since 10.4 was so good on my MDD, but I found it to be really good, way more I would have expected.

I think your main issue would be with how much RAM you have there and how old (slow) your hard disk is.
Maybe the main 'marketing' downside is the lack of a Core-Image-Video able GPU, features my MDD doesn't have either BUT all in all there is no way I am going back to Tiger.

This friend had also installed 10.5 on a PowerBook Ti 500MHz, now that is slow… so if you can actually BACK UP your current hard disk I would give it a try… I guess archive and install is also an option, I have never done that since I rely on SuperDuper.
