Despite the fact I loved the machine, it went into the back of the wardrobe for a number of reasons. Firstly, at that point, I had already got two other iMac G4's. A 800MHz 15 inch my sister used as a jukebox with the pro speakers, and a top of the line, mid 2004 (one of the last) 17 inch iMacs with a 1.25GHz processor and an iSight mounted to it! Happily, TenFourFox is a modern fork of Firefox created for G3, G4 and G5 Macs. And if you’re rocking an even older system, check out Classilla for Mac OS 9 (and even 8.6). Use an old Mac as a.
- And for the G4 be sure to choose Apple Partition Map for the Partition Map Scheme. Next, you need a backup/cloning program. You could get either Carbon Copy Cloner (paid) or SuperDuper, free for the initial backup, but you need to pay to have it run incremental backups thereafter, which of course you should do.
- IMac DV systems play a special role in the Museum showcasing the evolution of Mac OS X: Sage, Ruby and Indigo units are loaded with Mac OS X 10.0.4 (Cheetah), 10.1.5 (Puma) and 10.2.8 (Jaguar) respectively. That’s how Time magazine described the iMac G4 when it was introduced.
- The iMac's included software is a solid collection, and all the programs run natively in Mac OS X-which makes sense because the iMac boots by default into Apple's new operating system.

Hello, I just want to share my experiences and solution with fixing my MDD PowerMac power supply.
Uninstall mcafee for mac. First some quick background:
A few years back my Mac would reset its clock back to December 31, 1969.
And at times it would not power-up unless I switched off/on the power switch on the power strip or unplug/plug the power cable.
I replaced the PRAM battery and reset the PMU.
The problem was intermittent and though it was slightly inconvenient I was able to deal with manually updating the date/time settings, etc.
A few weeks ago, I decided to give the inside of my Mac a quick spring cleaning.
When I tried to turn it back on, it was completely unresponsive.
Since I knew the PSU, was prone to catastrophe I decided to open it up and take a peek.
But first a disclaimer:

I am not an expert in electrical engineering so my 'solution' may not (or it may) work for your particular case. Additionally I simply stumbled upon this quick solution while I was 'poking' around.
When you open up the PSU you should see something that looks like a cathode terminal, a few inches from this is a heat sink. If you happen to accidently touch both pieces at the same time you will receive a nice buzz. That is because the PSU and its capacitors/inductors have electrical charge stored in them.
What I did was simply arc the two pieces of metal using a thick screw driver with a rubber grip. This short circuit will simply discharge the PSU and you will see a spark or two as the electrical current finds the ground. (it also leaves a nice little nick on the shaft of you screw driver)
(That whole last part maybe a bit unneccessary, but it sure is fun to do and it brings back memories of how we use to 'hotwire' our HMMWVs)
After checking with a multimeter, I verified that the PSU was getting the correct input voltage.

My next logical step was to check output voltage.
Since I didn't know what to look for in the PSU, I closed it back up.
(I should mention that there were no signs of burnt or exploded circuits, diodes, capacitors etc. and that I could not locate a standard fuse.. Encarta kids 2009 download. it turns out the fuse is a built-in 250 V - 8 amp ceramic fuse and proximal to where the power cord enters the PSU)
The next step was to test the output voltage, so I figured I'll check it at the terminal where it connects to the logic board.
I googled the pin out and then I checked the voltage.

Since I was getting the right voltages I put everything back together and then.. VOILA.
My Mac powered on flawlessly, even the date and time settings were preserved.
Hopefully this it will work for others. I am not sure why it worked, but it did after I was unable to power-up my Mac.
With this quick solution I was able to bring my Mac back to life three times using that last trick.
What I simply did was measure the voltage with a multimeter between, if I recall correctly, were Pins 11 and 12.
Try that combination: between Power On and Ground or between the +25 V Standby and Ground.
Thanks for reading. Hopefully this helps out. Let us know if it does.
