RE: Back to my old English P.C.... And the pains of setting up MetaMask AGAIN!

The main computer I use for work is a Macbook Air (sorry!) because ever since I bought my first one four years ago now it just works very smoothly and with no problems at all for everything work related.

Don't apologize; use your Mac proudly. The only advantage PCs have is for gaming. Macs usually cost more, but they also usually last longer and work better. My last two laptops lasted over ten years. Actually the last one still works fine, but it's old enough now that it can't keep up with modern software so well so I had to upgrade for work reasons (and let me tell you, these latest ones with the Apple Silicon chips are really fast).
