Is it possible to put leopard on my G4?
I have a dual 800 system and i was wondering if there was a way to up the speed without buying a new processor so i can install Leopard on my system.
The G4 Quicksilver came in 533MHz, 667MHz, 733MHz, 800MHz, 933MHz, And 1.0GHz speeds.
The easiest way to trick Leopard into installing on G4 hardware with processors below the minimum clock speed is to use a program called LeopardAssist:
It automates the process of temporarily setting the PRAM to report the processor clock speed as 933MHz. I've used this program to install 10.5 on a 733MHz Digital Audio and a 700MHz iMac Flat Panel. This iMac is not a daily driver, I only use it to maintain my business iWeb pages and to pre-fill a few business forms for printing.
The Dual cores will help in normal day-to-day operations, so Leopard won't be painful to use. Put as much RAM into the machine as you can get your hands on, as well.
As an aside, I've successfully booted machines with well below the RAM and processor speed requirements using an external drive already containing a bootable Leopard payload. The result was not pleasant, but handy for troubleshooting...
I installed Leopard onto a G4 Sawtooth 400MHz and it ran acceptably with Spotlight turned off. So your dual 800 should be just fine. But as was said before dump as much RAM in there as you can because it'll really help general multitasking in Leopard especially.
