Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

So if I can't boot into the OS how is one supposed to turn off Activation Lock?

I'm trying to recover the MacBook Air, I'm trying to install OS Catalina from a USB thumb drive.

  • The Mac can't boot normally.
  • It can't boot into OS recovery Mode, 'Command+R'
  • The Mac can't recover from the internet recovery screen, just shows a -1008F error after 10mins

Is there a ways to hardware force the mac into recovery mode so I can install from a USB?

So you have successfully painted yourself into a corner with your stipulations.


To access "installationOS" to create a USBinstaller requires Internet access as well...


If this is a notebook it is easy enough to try a different Network: ex, sit outside a Starbucks, Laundry mat, McDonalds, Public Library— all tend to offer high Speed wireless Internet.


If you have another Mac that is functioning on your Network:

Unfortunately it is slow and dodgy Internet/download speed that tends to corrupt/interrupt a viable install package.

If your Mac starts up to error -1008F

Your Network is inadequate in some fashion.. try a faster Networks and see if it is a simple resolve.


-1008F error...


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.

Thanks for getting back to me.

As I mentioned, can't boot the machine at all. So can't turn anything on or off except the hardware.


My internet is very slow and intermittent and so that could be the problem.
