What are you on about? Somewhere else you said that Firefox alone causes “your” 8gb Mac to stutter.

That’s bull.

My personal Mac is a 32GB Macbook Pro, but we have an 8GB M1 iMac in our house that I actually use frequently. We picked it up as an open box item at Best Buy about a month after it came out. Just a couple of weeks ago I edited a wedding video on it when I’d accidentally left my Macbook at a friends house about an hour away. Final Cut handled three streams of 4k video just fine on 8GB. We are constantly using it as the primary slicer for files for our 3D printer. My kids run games on it using both Dolphin and Wine without issues.

And I’m not the only person who has done these things. There are people all over YouTube (especially two years ago) who were benchmarking and using the entry level M1 Macs for things just like this without the issues you are describing.

Just one very early example: https://www.youtube.com/watch?v=WUXZBVLFNfY

If you genuinely can’t even run Firefox without performance issues there’s something wrong with your machine specifically.
