My video points out that for some users, 8GB can be enough, but it depends on the type of tasks you are doing. For most users, going to 16GB will just improve your experience and also ensure your computer will last longer due to rising RAM usage in apps.8GB of RAM on the M-Series Macs is perfectly fine for base spec users. And it outperforms 16GB Intel Macs and other 16GB Intel systems I’ve used.
I also point out that 12GB could be fine as well but that’s not a config Apple typically offers. I’d personally love to see them using a base-12 system instead of a base-8 system.
