This error can sometimes occur when you are trying to use Recovery Mode to access the Apple servers using a wireless connection. Have you tried temporarily connecting your notebook directly to your Internet router by Ethernet? If your notebook does not have a dedicated Ethernet port (the newest ones don't) you will need to get a USB-C-to-Ethernet adapter for this. These will become handy for things like this in the future.

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.
