Re: A1466 bios passWORD help

I've removed the password from the bin file.
Let us know if this works.

Also same file , I think my programmer corrupted this dump first time I read it, the Mac only turns fan now , no display, even with the first file , is there any way to fix the dump? No display but fan is running

Did you erase flash, write and then verify the new ROM file?
You may also need to do a option-cmd-p-r three boots to clear any previous settings.

BIOS guides, methods, resources and tools -> https://www.badcaps.net/forum/showthread.php?t=103526 3. Password removal by laptop brand -> https://www.badcaps.net/forum/showpo...42&postcount=4
3.2. Apple -> 3.2.2. 2012 to 2017

For 2012 to 2017 machines, BIOS must be edited and reflashed to clear the password. There are 2 methods for this:

Clear out the whole SVS store. There are other stuff in this store, no idea what they are for so better avoid doing this.
Invalidate the CBF2CC32 NVRAM variable in that SVS store which contains the encrypted password. You just have to change one bit in its name, so like replace the C with an A or whatever. Note that strings are UCS-2 encoded, so in the hex editor it'll show up as 0x43 0x00 0x42 0x00 0x46 0x00 etc.

If there is an iCloud pin, you need to perform 3x PRAM reset after removing password. If FindMyMac is still enabled, you have to reinstall macOS while being disconnected from the Internet, then reconnect after logging in and bind to a new Apple account.

It may be that the SSD is formatted as APFS but the BIOS in your Mac is old and it won't recognise this formatting. Try booting from a Mac installation and then see if the SSD appears. Format as EXTFS+ and reinstall.

Does not show INTERNAL Recovery Utility After Pressing CMD + R, it only goes to INTERNET RECOVERY, I tried to connect Wifi, and do recovery nothing it just goes back to the same spot

Re: Mac air a1466-820-00165-a-lock

It's worth getting a USB stick and putting a MACOS installer on it (say Monterey).
I have many USB sticks for each version of MACOS.
This should boot and allow you to reinstall.
I never use internet recovery.
Good luck!

I have downloaded an INSTALLASISTANT.PKG and I took another Macbook, I installed it and it opens a bucnch of files, I created a bootable disk using my External SSD, I go to my Macbook air, connected EXTERNAL SSD, pressed CMD+R,, and nothing comes up except INTERNET RECOVERY!!! Am I missing something? Please bear with me

Re: Mac air a1466-820-00165-a-lock

You should hold the option key as it boots and select the external SSD installer.
