Question about Apple (661-2795) for iMac Motherboard

1 Answer

Blue iMac I am trying to upgrade my Mom's iMac M5221 computer to Panther 10.3 so she can us the Safari browser. I purchased the OS on CD because the computer does not read DVD's. In the install process, it would not install, but kept going to a blue screen with a spinning disk icon. In trying to do Disk Utility, the HD would not show. I purchased a re-conditioned HD, which showed and tried to install the software again. I am now getting the same error. The HD shows and appears OK with the Disk Utility check but the software will not install. I KNOW the software is OK because it is original Apple and brand new. Can you advise? I have already put too much money into this to give up or should I?

It sounds like there's underlying problems unrelated to Panther. If the computer boots from the the old HD, but then the HD didn't show under Disk Utility, this is an intermittent problem. Try replacing the cable that goes to the HD (if there is one), it may have become damaged sufficiently that things aren't working under "heavy use" (like trying to install an OS). If there is no cable, or replacing it doesn't work, I'd suggest putting the original HD in and selling the computer as-is. Again, if it still botos from the old HD, then it's not a problem with the HD or Panther, unless the reconditioned HD you bought was faulty (unlikely but possible). More likely is when you installed the reconditioned HD, something else changes (e.g. connection made better contact) that caused the HD to show.

How to Add Life and Pep to an iMac G3

The old iMac G3 desktop was an excellent machine in its day. Today, it can still be a great little computer to scoot around the Internet, create graphics, manipulate photos, and do schoolwork or almost any other use you can imagine.

If you haven’t already upgraded to OS X 10.4 (Tiger), you should deeply consider doing this. Currently, this version of the Mac operating system is the earliest still being supported by major browsers, and is the newest that works well on the iMac G3. If you can’t upgrade to Tiger, consider using Panther (OS X 10.3).

After you update your operating system, download the latest version of your favorite browser. Remember; Microsoft stopped including Macintosh in its updates of Internet Explorer when Mac launched Safari, so all Mac versions are sorely out of date. Firefox, Opera, Camino and, of course the default Mac browser, Safari, are the best browsers for your iMac. If you can only use Panther, the Opera browser is the only one still including Panther in updates. Also, if you enjoy using Yahoo! Messenger, Panther and earlier are not supported by Yahoo! Messenger either. Unfortunately, time has marched on. You can, however, use the web version of Yahoo! Messenger through your browser.

Update your software using the Software Update feature found in the System section of the System Preferences dialog box. Changes to Java, QuickTime and other frequently used components have more than likely occurred since your OS was created and updates are important to keeping your machine running on today’s web.

Replacing your CPU is not suggested due to the difficulty level, but a quick fix of RAM can give your elderly machine a big boost of energy. The later G3’s can handle 1 GB of SDRAM, just use two 512 MB sticks. You can find these for a good price on eBay.

Once you have all these upgrades and updates, your little iMac will be the fierce web adventurer it once was. Happy computing!

This is a question from a friend of mine who recently was given a used imac. Any ideas what he can try doing? when I plug it in and turn it on I get a grey screen with a little icon in the middle (looks...

What your friend is seeing, is an indicator that the Mac 333 Mhz, is not able to boot up to recognizable Mac OS volume. This means that Mac OS volume is either damaged or has some how been corrupted.

Apple advises the only fixes for such an issue with this class of their "legacy computer" series is to back up the data on the hard drive if possible and reinstall the Mac OS version is was operating with, or simply go a step further and upgrade to the highest version of the Mac OS X family of operating systems, that this iMac G3 qualifies for.

Here is a link from Apple support for resolving this issue for this legacy mode;
Macintosh starts up to Grey Screen

If your friend is interested in knowing what is the highest version of Mac OS X he can install on his iMac 333,, it would be Mac OS X 10.3 Panther.

This version is the highest upgrade for the iMac 333 because Mac OS X 10.4 Tiger will only work with Macs that have a built-in Firewire port.

Here is the technical specifications link from Apple for this model:
Technical Specifications - iMac 333 Ghz (1999)

This should help.

Reastart the iMac and at the same time hold down the mouse left click button. If that does not work.
  1. Restart the computer.
  2. Immediately after the startup sound, press and hold the key combination Command-Option-O-F.
    Note: The Command key has the Apple and (commandkeysymbol.gif) icons on it.
  3. Release the keys when you see a white screen that says "Welcome to Open Firmware."
  4. At the prompt, type: eject cd
  5. Press Return, then wait a few seconds. The disc drive should eject any disc that is present, and "ok" appears behind your command when the action is complete.
  6. Type: mac-boot
  7. Press Return.

That Mac will run 10.4 Tiger, but I would recommend 10.3 Panther. You can download all updates through sofware update after the install is complete. You should be able to find installer disks on eBay for cheap.

Browser Interface

Hi Duaine06!

In some cases, some setup wizard will not run at Mac OS. Maybe that's the problem that you have right now.

Regarding the incomplete menus when accessing it with Safari (I assumed) another way is to download Mozilla Firefox and try it there. This is just a suggestion that you can try. It works for me when I encountered this problem.

But incase that the menus are still incomplete with both Safari and Mozilla then it might be a firwmare issue with your device. Try and update it.

Hope this helps!
