Ordering Refurbished MBA M4 question

[OldMacs4Me]

So I would like to order a refurbished MacBook Air M4
, but have one improtant question. Assuming it ships with Tahoe can I revert it to Sequoia? Or will there be a firmware update in place that prevents that?

It's for my wife who is not in great health and can be guaranteed to dislike the 'improvements' found in Tahoe.

Found no 800 number or other quick contact on the Apple website, though they may have put that in my blind spot.

I don’t think so…. If I recall, you can always wipe the drive clean and do a clean install of the OS regardless of version.

Well, not regardless of version of macOS. Typically, at minimum, you can install the version of macOS that the model originally shipped when released.

As Bigwaff mentioned, you can only go back to the OS the unit was shipped with.

For curiosity’s sake, here is a write up of all that’s involved. Sites also mention that one can introduce issues/ conflicts, if new firmware was involved and then resides with an older macOS version.

There is always the upcoming macOS 27 that (on paper) looks promising.

The M4 MBA originally shipped with OS 15.3 Sequoia. So, the answer is YES❗️
