Installing new system software on G4 imac where system removed

Hi, I sure hope you can help me. I have a G4, 80 gb, 800 mhz Imac that I picked up for free on freecycle and I know, for a fact, it's in great running order. It has had the hard drive removed and when I start it up, I get the flashing file with the question mark which I understand in normal when the system software has been removed. I need to know how I can install a new operating system and which operating system I can install. I have Jaguar - will that work? Also, because I don't know a lot about the technical side of Mac, do I need install the original operating system in order upgrade? I'd love to get this up and going today.
Thanks, in advance, for your guidance.

    Thanks. I have Jaguar from another Mac I have and was going to try that but if I HAVE to purchase a new version, I think I did pretty well considering my investment in the computer itself was nothing. Thanks. I'll let you know what I end up having to do.

    I don't have the disk yet - my daughter is bringing it to me a little later today. I understand if it's the recovery disk for a system that had Jaguar as it's original operating system, it probably won't work. It's it the retail version, it should. I have to see the disk to see which it is. I THINK it's the retail, which would be sweet. Thanks

You will definitely need a hard drive to make this work. If I remember right the IDE HD is located beneath the removable cover on the bottom where the memory goes. I don't know if you can use an external USB HD but it may be an option.

I bought a g5 dual core from a friend with out a hard drive. I then went to a mac shop and bought a new hard drive and leopard system 10.5.4. I can't get the g5 to see the new hard drive and have no other boot disk other than the new leopard installation disk. How do I get the g5 to mount or see the new hard drive.

Well the flashing question mark means its not finding a bootable device meaning the hard drive has no OS on it. You should be able to put jaguar on it if its a retail version and not one from another mac product. Let me know how this works for you

Sims 3 won't install on my imac G4. I have Leopard 10.8 so I have the correct system requirements. When I click on install it keeps coming up Not supported on this architecture?


If you read the system requirements of Sims 3, it says that you need at least an Intel Core Duo processor, which the iMac G4 does not have. The iMac G4 has a PowerPC processor.

Thanks for the help!


Hi there,

That sounds like it would fix it. Have you recently updated the memory in the imac? It may be incompatable. Otherwise it may simply have become faulty over time.

Please make sure that before you open up your imac, you're not voiding your warrenty. I know that the aluminium imacs allow this, but i dont think the G4 versions do.

Hope this helps,

Nathan.

My G4 1.25ghz with 1 gb ram plays abc video slow.


Hello, sorry you are having trouble,
There are so many variables when it comes to Video play back on a Mac..
Yea, 1.25 Ghz with 1 GB of Ram answers most questions, yea, it should play OK,
BUT:
  • Is the video on a CD or DVD ? well, these iMacs don't have a very fast optical drive.
  • How much room do you have on your internal hard Drive, if it's too full ( more than 80% full ) then you will suffer read/write performance.
  • Is the video on an external harddrive, is it a USB drive? the USB on the iMac G4 is USB 1.1, 11Mbit/sec, way too slow to play a big video smoothly.
  • Just what is the size of the video, is it like that for all of them or just one, might it be a HD video with high frame rates?
  • What version of the MacOS X do you have installed? If you installed Leopard 10.5 on the iMac G4, nothing will run smoothly,
  • Are you playing this video over a network? forget it it's got to be on the internal or a FireWire external disk otherwise it will stagger...
Well, there you go, I know, it's so easy to say Hey man, just get a new Mac and everything will be fine... But that machine is going on 6 years old now, Video technology has not stood still.....

''imac g4 does not see dvd drive after Xferring files and setting


when booting in os x after the first boot chime immediately hold down keys <apple,option,o,f> all at the same time and allow computer to boot to open firmware once there type "reset-nvram" exactly like that but without quotation marks and press enter once it returns to command prompt type "reset-all"and press enter (you must have the "-" in between the commands) the computer should restart if not when the command prompt returns type "reboot" and hit enter ..... also you can check the drive status by going to "system profiler" in apple drop down menu--->about this mac-->more info or applications folder-->utilities folder--->system profiler then selct disk burning under hardware in the list on the left

Problem with Apple imac Power Supply


The most common problem with imac G4/800's are failing logic-boards. This will cause the mac to not power up at all giving the impression that the PSU is broken. 
If however, you are indeed certain that the fault is with the power supply, they are available from many stores online
