Being able to upgrade your computer isn’t anything that Mac users often hear or do. Apple has always been quite conservative with the idea of users making internal hardware changes to their Mac. The recently announced iMac goes against that idea as a recent teardown of the computer reveals that the device is indeed upgradable.
Till now, if you talk about upgrading a Mac, it was obvious that all would be done by the Apple folks themselves and that too only before you purchase the Mac. Apple gives you some limited options to upgrade your Mac while purchasing but there has been no case when the company entertained upgradation later.
iFixit performed the teardown of the recently announced 21.5-inch iMac with Retina 4K Display and found out that its RAM and CPU could be replaced. This is a first to be seen in several years on an Apple machine.
As a matter of fact, the 21.5-inch iMac with Retina 4K Display isn’t officially upgradable, it is just what the teardown revealed. If you go ahead and replace the RAM and CPU that the machine originally came with, or even open your iMac yourself, you will end up getting your warranty voided.
Even if you decide to void the warranty, you will need specialized tools, guide, and of course skill to reach the internals of an iMac. Remember that upgradability doesn’t mean a better repairability score; iFixit has given it a just 3/10 meaning it is quite hard to open and repair.
The 2017 MacBook and MacBook Pro also got a teardown treatment from iFixit but both the laptops ended up with a poor score of 1/10. Not much has changed in these two devices and they are still glued-up like their predecessors. However, a 9To5Mac report mentions that the laptops now come with the second generation of butterfly keyboard that is believed to be more responsive.
