I have an MacBook Air intel (2020). I’m really tempted to just sell it or trade it in and get a m1 or m2 air. I have an m2 air for work. The only downside is 1 external monitor but I’ll probably never use it that way. I will miss being able to use virtual box. I know time is running out on the intel variants though.
They’ll be supported by Linux
Intel will get this year’s update, and next year’s update and be canned after that.
Not sure they will give you a choice. I just had to give up my intel 16 inch due to it throttling all the cpus down. Even the jet engines couldn’t keep it cool enough to not throttle.
You can always upgrade them to a Linux distro. I run my Mac with fedora.
Do you use a mouse or trackpad? Last time I used Linux on a Mac my only issues with loss of smooth trackpad.
Is it better to run a linux distro on an old mac or go for an older OSX version?
Well you can just have an up to date Linux system, that can be as bloated or bloatless as you want. It may take away some battery life and cause some thermal issues because of how Apple designs their products though, but you can probably fix that with some fiddling.
Really if you have the know-how, you can configure Linux any way you want.
