While Apple’s computers have never really been what you would call customizable (save for the Mac Pro), some of them do support user upgrades to a certain extent, like the iMac which features a backdoor that lets users add extra RAM modules themselves quickly, easily, and not to mention safely.
However, the newer M1 Mac computers have become even less upgradeable than before, but it turns out that you can upgrade them if you wish. This is according to reports in which it claims that engineers in China have found a way to expand on the storage and the RAM of the M1 Mac mini, bumping it from 8GB to 16GB of RAM, and storage from 256GB to 1TB.
Now before you get too excited that upgrading your M1 Mac mini, there are several reasons you shouldn’t do this. For starters, it would most certainly void your warranty, unlike the RAM upgrade in the iMac which actually doesn’t. Secondly, it would require you to desolder the modules in the Mac mini and if you have no experience doing this, there’s a good chance you end up destroying your entire computer.
Lastly, it’s not as easy to get your hands on DRAM and NAND chips that are used in the Mac mini as they are not exactly commercially available. The takeaway from this is that yes, these Apple Silicon computers can be upgraded, but whether or not you should is a different story.
