First of all, thank you very much for your response! My grilfriend has a MacBook Air (13,3" - 2017) which is obviously not supported anymore for OS updates greater than Monterey. So, you are saying more or less that I should not buy a Refurbished one as they are most of the time older (let's say around 2020) when you say the currently available will have similar levels of ongoing support? Why not going for Intel?

Addition: With "Support" in my question I mean how long can I get Mac OS Updates to upgrade to a new Mac OS Version not only within a certain Version. It turned out that XCode and OS are somehow closely coupled (nobody in a Linux/Windows World understands why), but if it is like that and I am not able to get newer XCode versions for me Support means just like that: "How long can I get Mac OS Upgrades"

Is there also something that might be affected by the RAM Size regarding longterm support or did it have not too much impact in the past? Currently, I thought about an Apple MacBook Air 2022 | 13.6" | M2 | 8 GB | 256 GB SSD What I wonder about, one Site mentioned Maximum OS Compatibility is macOS Monetery (?) and the other one also said that Monterey is installed? But, on [https://support.apple.com/en-us/105113), I see it compatible with Sonoma.

Was more directed regarding future versions. I don't know how much the hardware requirements changed over past versions. On a Windows-Machine, I would have said okay for now sufficient and when RAM requirements increase buy some additional 8 GB. But, here it's sad they have integrated everything non extensible :( But anyway, thank you very much for all your responses and your help on that - it really did!
