leopard will not install

[bcvcdc]

I have an imac osx version 10.3.9 (panther) with 800 mhz processor and 768 mb memory. like an idiot i recently bought leopard to upgrade which requires 867 mhz processor speed. so, i can't install it on this computer, but my problem is that i can't access a lot of things on the internet with my current system, most importantly i can't access my .mac account. any suggestions as to what i can do here?

You can force it to install, but you still will not be able to access a lot of things on the internet. IIRC, you would need to upgrade your RAM as well.

I'd recommend that you get Tiger.

768 meg is enough for Leopard. I ran it fine with 512 mb on an iBook G4 1.33 ghz. Doing a force install requires alering the Leopard install files. There are guides on the web that can be found via google or mroogle search.

What are you having difficulty accessing?

What G4 do you have? I have a 466Mhz DA with 768MB ram and it runs leopard well enough. I did not notice a speed difference from Tiger. Just don't have multiple programs open at once and you should be fine.

Here is instructions for the install I posted in another thread.

You don't need to make .dmg's and tweak the installer. There is a simple open firmware trick that works great. It simply makes the installer think you have an 867mhz G4. I used it for a 466mhz DA without a problem.

To install Leopard on an "unsupported" G4 clocked under 867 MHz:
1. Reboot your Mac and hold down the Cmd-Opt-O-F keys until you get a white screen with black text. This is the Open Firmware prompt.
2. Insert the Mac OS X Leopard Install DVD.
3. Type the following lines exactly as shown below into the Open Firmware prompt. Be mindful of capitalization, spaces, zeros, etc. If the command is properly typed and understood, Open Firmware will display "ok" at the end of each line after you hit "return". What these lines do is set the CPU speed reported by Open Firmware to OS X as an 867 MHz G4 processor system. They then continue the boot from the DVD drive.
For single CPUs, use the following three lines:
dev /cpus/PowerPC,G4@0
d# 867000000 encode-int " clock-frequency" property
boot cd:,\\:tbxi
For dual CPUs, use the following five lines:
dev /cpus/PowerPC,G4@0
d# 867000000 encode-int " clock-frequency" property
dev /cpus/PowerPC,G4@1
d# 867000000 encode-int " clock-frequency" property
boot cd:,\\:tbxi
4. Continue the install normally.
5. This CPU setting is only in effect until the Mac reboots. Once OS X Leopard is installed and your Mac has rebooted, the proper CPU speed should once again be displayed when you select About This Mac under the Apple menu.

Thanks everybody,

r.j.s. - yeah, I should have gotten Tiger but I'm now stuck with Leopard.

old-wiz - it's not the ram that's the problem, it's the CPU speed I think. I'm having trouble accessing my .mac account. - Oh, I just looked again, it's my browser that needs to be updated.

velocityG4 - I have a PowerPC G4 (2.1). And thanks for your help and info.

Oh, here's the problem -
Macintosh Requirements for Safari 4
*Any Mac running Security Update 2009-001 and Mac OS X Leopard 10.5.6 or Mac OS X Tiger 10.4.11
*Mac with an Intel processor or a Power PC G5, G4, or G3 processor and built-in FireWire®
*256MB of RAM
*Top Sites and Cover Flow on Mac OS X Tiger require a Quartz-Extreme compatible video card.

So, I don't have Tiger but can't install Leopard (well without getting a huge headache, being the non-techie that I am).
