I think it depends on what was the current version when your model came out. Should have said mid-2014 like OP, sorry

> Should have said mid-2014 like OP, sorry I don't want to belabor the point, but just to be clear—I am referring to a mid-2014 MBA, anything newer and Mavericks wouldn't work! (There is no "late 2014" MBA as far as I'm aware.) Mine offers to install Yosemite in recovery mode. It may indeed be based on when that specific computer came off of the assembly line or something, I have no idea, but for that exact model of computer you can get different results in recovery mode!

  Good to know. Mine is from June 2014 (assembly, since it’s a custom configuration). Sorry for missing your point.

  There are multiple boot-time recovery options, but you might not have a required firmware update to use them. Per everymac, all 2014 MBA’s should be able to run up to Big Sur?

You can usually install the firmware updates without updating macOS, but finding them is usually the harder part. You could probably swap hard drives to a scratch SSD if you wanted to update your firmware via updating macOS entirely without affecting your live install, or install macOS on a USB drive, which should not affect your internal SSD install, but like all upgrades, have a backup or pull the internal SSD.

    I don’t know, I’ve performed numerous updates from the pre-installed Mavericks (Yosemite, El Capitan, High Sierra, Big Sur are the ones I remember, might be more), but the default recovery still goes into Mavericks for me

      You might need to update the firmware for your Mac in order for the Internet Recovery to support updating to Big Sur.

        Big Sur Recovery mode works for me with Option+Cmd+R, so if needed I can install that. What I meant is that the other goes into Mavericks Recovery mode. And I’m happy about that actually :-) Edit: if you were referring to Option+Cmd+R anyway, I guess I misread Edit2: by other one I meant Shift+Option+Cmd+R, just Cmd+R actually goes into Big Sur, you are right!

        Yeah, there are a few keyboard combinations that do different things. https://support.apple.com/en-us/102655 https://support.apple.com/en-us/102655 > On an Intel-based Mac: > If you used Command-R to start up from the local Recovery system, you get the current version of the most recently installed macOS. > If you used Option-Command-R to start up from Internet Recovery, you might get the latest macOS that is compatible with your Mac. > If you used Shift-Option-Command-R to start up from Internet Recovery, you might get the macOS that came with your Mac, or the closest version still available.

  I guess I was also confused about the different recovery modes as pointed out by aspenmayer below. I used Shift+Option+Command+R (or hold Option and choose WiFi instead of disk) which is internet recovery using the macOS version that came pre-installed (or closest) Whereas Command+R is local recovery which might be any macOS version that last changed the local recovery environment.
