Macbook Air Purchase: Worth it for security reasons?

Was in same boat as you. Laptop with Linux crapped out (hardware) and needed a new one. Ended up going with MacBook Pro M4 which is overkill for my needs but I love the 16in screen. Anyway, I already have an iPhone I hardened using PG hardening guide and Mac just works seamlessly with it. Having iMessage and Signal and iCloud with ADP on Mac has been great too.

that said, my gaming PC now runs Fedora Linux. Out of all the games I’ve played over the past year I’ve never once had to boot back into Windows to play a game (Repo, Peak, Death Stranding, Red Dead Redemption 1 & 2, Invokyr, etc.) - Steam handles all the switcheroo stuff in the background. I can’t see a reason for gamers to not have a dual boot setup on their gaming PCs. I know that’s not what u asked, but saw some people mention Linux here and have to say I’ve been blown away with how good Fedora is.

so, Fedora Linux Gaming PC + MacBook M4 has been my angle and I’m loving it.
