Shyos Posted November 1, 2007 Share Posted November 1, 2007 I've tried to install Leopard on my old PowerPC G4 800 Mhz... but I get the message that this cannot be installed. Is this because Leopard isn't installable on a PowerPC G4 or am I doing something wrong here? Thanks in advance! Link to comment Share on other sites More sharing options...

Thanks in advance! I assume you have a quicksilver. You can either install it on another machine that meets the minimum of 867mhz and swap the drive or you can overclock your cpu 1 step. I choose the latter. Just bridge the contacts with solder. http://power-mac-g4.com/g4quicksilverclockup.html Good luck. Link to comment Share on other sites More sharing options...
Synaesthesia Posted November 1, 2007 Share Posted November 1, 2007 Yeah, the minimum requirement is 867mhz,but in addition to overclocking your mac or swapping disks. but you can also install via a firewire cable as well, or some other method. Here is a guy who installed successfully onto a 700mhz iMac, and another one on a dual G4 500mhz. Best of luck. Edit: yet another method (hope you aren't overly inundated now) Link to comment Share on other sites More sharing options...
Headrush69 Posted November 1, 2007 Share Posted November 1, 2007 Replacing the OSInstall.mpkg with a modified one that avoids the check, (a link can be found in this forum or PM), and then you can reburn the DVD or temporarily use an external drive with the modified OSInstall.mpkg and it will install.

scj312 Posted November 2, 2007 Share Posted November 2, 2007 I'm running it on my 800MHz iMac using the OSInstall.mpkg hack. Link to comment Share on other sites More sharing options...
learning_bird Posted November 2, 2007 Share Posted November 2, 2007 Writing from Leopard/Safari 3.0 on my 800 MHz QS 2002! Just for testing Leopard I've used a new 80 GB ATA drive on a firewire case attached to my Powerbook. After the clean install I swapped the HD to the PowerMac and everything went OK. I knew beforehand that the graphic card would be too weak to power Time Machine so I didn't even try it. I also disabled the mirroring on the Dock because I was seeing some tearing over the Dock which I assumed was due to the graphic card. Problem solved! In terms of performance, Leopard on this Mac isn't either faster or slower but it is obvious that it hasn't enough muscle to fully profit from Leopard. I was also amazed that every app that I've tried installed and worked fine. All in all, a good experience. Link to comment Share on other sites More sharing options...

oldschool Posted November 2, 2007 Share Posted November 2, 2007 Before the OSInstall.mpkg releases it was an adventures to mod this little one... My QS 800 runs great with Leopard... Btw, you need definitely a BIG G-Card (9800 or something simliar)! Link to comment Share on other sites More sharing options...

I think the latest PowerMacs ( from the QuickSilver ) are very capable Leopard machines if they have the original graphic cards upgraded. Link to comment Share on other sites More sharing options...
Shyos Posted November 7, 2007 Author Share Posted November 7, 2007 Thanks to your help I finally managed to get Leopard installed on my 800Ghz iMac flatscreen!
