This is the only way you’ll be able to boot OS X on these older iMacs. A-D iMac, add a hard drive bigger than 8 GB, and there’s any possibility at all that you’ll run OS X on it at some point, be sure to partition the drive with a first partition no larger than 8 GB. You’ll probably make your iMac faster at the same time, since today’s hard drives tend to be faster than the ones Apple put in these iMacs. The older iMacs use the common IDE hard drive interface, so finding a compatible hard drive shouldn’t be a problem, and when you do find one, it shouldn’t be too expensive either. But for people with the smaller hard drives found in earlier iMacs, upgrading to a larger hard drive might be an appropriate option. For most people, the 40 GB hard drive found in today’s 600 MHz iMac will probably be sufficient. However, with huge office programs and 1000+ song MP3 collections, a larger hard drive will probably be necessary. The iMac’s 4 GB hard drive was thought to be huge when it first rolled out. As we go to press, 128 MB SO-DIMMs go for as little as US$19, 256 MB for $44 and up, 128 MB PC100 as low as $19, 256 MB from $31, and 512 MB starts at $60.

However, memory is probably the cheapest way to speed up your older iMac.įor current prices on SO-DIMM and PC100 memory to upgrade your iMac, check out the latest deals listed at Other World Computing. Depending on how you’ll use your newly improved iMac, 256 MB will probably be fine. They all support much higher amounts of RAM, up to one gigabyte. The later revisions, 350 MHz and up, use the more common PC100 RAM, which can be more readily found – and at lower prices. We have not been able to determine why there is so little consistency among tray-loading iMacs.

Ds at Low End Mac headquarters – one takes a 256 MB upgrade, but the other won’t. Some manage to get two 256 MB modules working others can’t get their computer to recognize anything larger than 128 MB. However, RAM upgrades are limited on the Rev A-D iMacs because they can only support up to 256 MB of RAM.Įditor’s note: Users have reported mixed results upgrading memory in the Rev. It can be found on eBay relatively cheap. These iMacs use SO-DIMM memory, the same type found in PowerBook G3s. The memory in the original 233-333 MHz iMacs (the ones with a tray for the CD, not a slot) can be pricier and more confusing than the RAM in other Macs from this era, such as the Blue and White G3. Upgrading the memory well beyond 32 MB should be a primary concern for most users. With enough memory, the iMac can handle Mac OS X 10.2 – and probably later versions when they come out.

This can be a problem for anyone wanting to run anything above Mac OS 8.1. The original iMac came with only 32 MB of RAM. See our Guide to iMac CPU Upgrades for more details on current and discontinued iMac processor upgrades. Some of these upgrade cards have features like FireWire ports (which aren’t available on the 350 MHz iMacs and below) or G4 processors, which can further your upgrade experience. Chris Lawson’s Upgrading an iMac article from 2000 provides an early look at these power-boosters. Sonnet and PowerLogix make upgrade cards for these computers, and Newer Tech used to (theirs are usually available through TechnoWarehouse). The easiest way to speed up an iMac is through a processor upgrade. Speed is probably the major concern when it comes to upgrading an older 233 MHz or 266 MHz iMac – or even a faster one. Today, we’ll talk about some of the options you have to supercharge your iMac. While there’s no feasible way to get the older iMacs to have the new styling and other features of the current iMac, there are still plenty of ways to get the pep back into these not-so-useless older iMacs. However, this is no reason to be discouraged. While many people lust for the new snow-colored iMac, many people are still left with a slightly fruitier variant of this computer on his or her desk. Now in its umpteenth revision, sporting LCD screens and faster than ever processors, the iMac has come quite a long way from the original 233 MHz Bondi blue bombshell. The iMac was and remains one of Apple’s best selling computers.
