2GB capacity T2 chip can control 1TB, 2TB, 4TB NAND.
So when 128GB, 256GB or 512GB NAND can use 1gb T2 For 1TB, 2TB or 4TB NAND,T2 chip must be 2GB.
i know this

This is a useful read to better understand how the T2 works.

Just found something interesting.

If you have an external disk with a MACOS installation (not an installer), you can boot from this if you hold CMD-R for a minute whilst it boots. You can release CMD-R once the loading bar appears. This will boot the recovery from the external disk instead of downloading it. I used Catalina, but others may work.

Once at the language selection, you can press CMD-T to bring up a Terminal.

Hi to all.
Sorry for my bad english.
I read all of 20th pages, and I want to thanks all.

I have an A2179 MBA with activation lock.
I have also the macbook password but the system said that I enter incorrect password too much time, an I can't use this method for bypass activation lock.
Moreover if I can find the complete email address of icloud I can retrieve the password.

What can I do? I have the new bridge.

I can boot with CMD+R and macOs hdd?
I don't be able to boot up with macOs external hdd.

Tks so much.

This can be able to bypass activation lock in my A2179 MBA, and boots up from external drive?
Have you use a usb-c hub, right? Or usb-c ssd directly?
Thanks

I booted from a USB external MACOS installation (I used micro SD card in a USB C adapter), but it only allows you to access a terminal.
I don't know how to activate from the terminal, but others may know how this can be done.

I have an A2179 MBA 2020 Activation locked, and I wanto to find the full iCloud email, because I know the previous owner.

How I can find this information?

In my case, I've reset the mac and I don't have the recovery installed, so when I press CMD+R with usb Hdd with Catalina Os attached at MBA, going out only the world with wifi "choose network" request, I think for download internet recovery.

One of the more recent updates has removed the choice to select the language before checking for activation lock. It's best not to reset or the method I described will never work.

You can find only if not erased and have old BridgeOS.
