Ladies and GentIemen, boys and girls!
Hi there,
I am in need of some help and sound advice.
I am about to upgrade my 15" G4 iMac 800 MHz to Tiger10.4.8 from Panther 10.3.9.
Are there any potential problems with an upgrade on this particular iMac that I should be looking out for?
The machine started out life with Jaguar 10.2 installed. The HD is a Western Digital 120Gb with 256 SDRAM fitted.
As always, I thank you all in advance for any advice.
best

My GF has a 17" G4 iMac 800MHz running Tiger without any issues. It is a little more resource hungry than Panther so your 256MB RAM will be a little starved. You really should pick up at least another 256 or better yet another 512.

Hi discotronic,
Thanks for your reply.
To tell you the truth I was a little worried about the 800MHz - I thought 1GHz was the minimum,(my 15" PB is 1GHz and runs 10.4.8 OK) although you seem to have no problems, very reasuring! You're right about the RAM - a stick of 512Mb should do the job!
Thanks again,

I have Tiger on a G3 700 mhz .. no problem, but I have sufficient RAM. I would second what disco said.. put 512 more.

regards

Tiger runs well on a 400MHz G3 iMac (but you will definitely need more RAM!). However, depending on your graphics card, you may not see all the visual effects that are present in 10.4 (you will get a simpler version of them).

Stuff as much RAM into that baby as you can possibly afford.

The minimum requirement for Tiger is a Mac with built-in Firewire. The iMac G4 is several generations after that. But yeah, the more RAM, the better.

Your CPU is fine, but aonther 512 ram is a must. You could get away with only another 256 if you don't run many apps at the same time.

It really depends on what you want to use the machine for. I have tiger on my 300mhz blue and white G3 (384mb ram I think) and it runs fine as a music server, but I can't say I would want to use it to do anything more than check my email or IM some friends.

CPU is fine, max the ram out!

My mom uses Tiger on a 466MHz G4 tower with some old hard drive and 512MB of RAM. Its a little slow but totally useable for web surfing and emailing and IMing. Though some web stuff is too slow, like java applets and probably most myspace pages.

Tiger works fine on that model (see my signature). CPU isn't a problem but you'll definitely want more RAM!
