How To Upgrade iMac Memory

A common complaint against iMacs is that you can’t upgrade the components in the device easily. Instead, you’re stuck with a devices that continually gets slower and less responsive when a few new parts would give the entire computer that much more time as a primary computer.

Much of that argument is true, but Apple makes it incredible easy to upgrade one of the most important components in any computer, Memory.

Never Buy Memory Upgrades from Apple

You should never, ever, buy a memory upgrade for an iMac from Apple for two reasons. First, the process is extremely easy. In fact, if you’re comfortable with a philips screw drive than you can upgrade the memory in your Mac.

Second, Apple prices memory upgrades at rates that are extremely high. In fact, I don’t think they ever even look at the current market price for RAM or memory upgrades. Instead, they keep a solid consistent price for anyone hoping to improve th performance of their iMac.

For example, this Corsair 8gb memory upgrade kit can be had on amazon for just $44.99. Apple would charge you $200 for a similar 8gb memory kit. That’s 4 times the rate available from other retailers.
