5101F?

Hello Bollis_1110,

Thank you for using Apple Support Communities. Based on your post, you have a used MacBook Pro that won't start up. You see error, 'apple.com/support -5101F. We'll do our best to assist.

It sounds like when you boot up, it's trying to boot to Internet recovery. Do you see a globe spinning on the screen as it starts up?

This may be helpful: If your Mac doesn't start up all the way

If the above isn't the case, has it ever started up successfully since you've purchased it? Was this purchased through a Reseller or a third-party?

Have you run diagnostics, prior to this post? If so, what were those results?

Hoping to hear back, take care.

Hey Bollis_1110,

It sounds like you were able to resolve these issues booting your MacBook Pro with Apple Support, is that right? You are able to use the Mac without any errors?

Have a good one, cheers.

You're welcome!

Have a lovely weekend, take care!
