-2002f

Hello, i was trying to reset my MacBook Pro totally. Then something happened, that resulted in my Mac shutting down. I then tried to restart my Mac, while holding option and r down. Then a globe appeared on my screen, and an option to connect to WiFi. I did that, and for 30 minutes nothing happened. After a long time the globe stopped spinning, and a exclamation point inside a triangle, then inside the globe appeared and said “-2002f”.... what do I do?

In Internet Recovery, these low negative thousands error messages indicate that your provided Wi-Fi Network is inadequate in some fashion, and cannot be used (for this purpose) in its current state.


Common problems include:

Hidden Network-name

required use of a proxy server to get Internet access

required use of a login page to get Internet access

Use of a login server or certificate to get Internet access

Use of PPPoE in the Mac to get Internet access (typically only applies to DSL)

Use of Fixed IP address rather than good old DHCP

Variance of the time by more than five minutes

Failure of Router to provide workable DNS server addresses, or providing 0.0.0.0 [may produce -2002f]


If you have an Ethernet port, you may in some cases be able to move your Mac close to the Router and connect to the Router using Ethernet.


The higher the number, the more obscure the problem.


Also, make certain the Date&Time and Time Zone are correct within 5 minutes.

You have provided no evidence of the current state of your Mac, only that you cannot successfully use Internet recovery, which you were invoking by holding command + R.


You got an error that said your Wi-FI as currently configured is inadequate to support Internet Recovery. My list above explains what some of the problems with Internet Recovery might be.


Try restarting and holding Option at startup. if there is a recovery partition available, try that. Otherwise, try any MacOS partition that appears.
