In Internet Recovery, these low negative thousands error messages (between -1000 and -6000) 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.
If your battery was completely depleted, the Date&Time could have reverted to the default, which will not work. There is a terminal command to reset to current Internet Date&Time -- post back for assistance.
Thank you! I had a conversation with Apple Support and they think it is a general failure to boot from the local disk - I am going to take it in to the Apple Store to see if they can figure anything out - the imac is from 2013 and has a load of data from my daughter's childhood that I want to keep - the machine dying is sort of expected, but I was hoping to get in one more time!
Thank you for your thorough reply!
One of the simplest thing your Mac can do is boot with Option key held down.
This starts a brute force search for bootable drives. An icon is added to the screen for each bootable drive discovered. After several minutes, the 'wait' cursor is replaced with a regular cursor.
No icons says no bootable drives discovered.
