Late 2010 MacBook Air (Intel) macOS Recovery won’t work

Thank you. Yes, the first two steps are the ones I followed plus ones about mounting the drives.

I did not come across the last one but most of those seem like options that require an operating system to be installed, so I can’t try them. The ones that don’t, like the restarting and trying MacOS Recovery, I have tried and they aren’t working.

I erased it using the erase software that comes with it, just like I’ve done before, more than once over the years, and intended to reinstall the OS using the recovery software just like before—but this time, I am getting all of these errors.

From macOS Utilities, if I try “Reinstall macOS,” it says “The recovery server could not be contacted.” I have full strength wifi bars, and it’s the same wifi set-up I used to do this (successfully) most recently.

Good news, though, this time when I chose “Restore From Time Machine Backup,” it DID find my HD.

So now I am restoring a full back-up from my external HD.

Assuming it works, I guess the question is how to erase all of my personal information without encountering this same inability to restore the OS.

Thank you for sharing your thoughts and helping troubleshoot!

Thanks. Unfortunately there is no ethernet port. I tried moving closer to the router but same issue.
