After about an hour, I see a -2003F fail code. All appearances suggest that the machine is trying a standard WiFi recovery. However when I choose that option, I'm immediately given the WiFi prompt again, and the USB light goes dead.

) When I start with the USB plugged in (via a USB to C connector) and hold the Option key, the USB flashes and I do see the Install Monterey option. (My other laptop is mid-2012, so I had to download the. I created a bootable USB with Monterey on it.

I've tried to boot to recovery mode via Command-r, but the machine only goes to the prompt to enter the WiFi name and password. At the 'Erase your Mac and reinstall MacOS' step, I followed.

I thought about taking the ssd out, put it in a case and try to format and install a new mac os on it on another mac. I even installed mac os sierra on an external HD and tried to boot from it, but - boot loop again.įrom disk util it shows that I have a recovery partition, but it never shows when I try to boot with the option key pressed.Īfter countless tries, turning the mac on and off, it finally booted with mojave but now I am afraid to turn it off, since I don't know if it's gonna boot ok again. I created a boot drive to format everything and start from scratch, but every single time I booted from it, it started the instalation and went right back into boot loop again. The only thing left to do was to reinstall a mac os and see if the wifi was gonna work. I deleted the faulty driver, then reseted the nvram, the SMC and restarted. The only way was to boot in safe mode, which I did, and it booted fine, but on safe mode. I tried then the Command+R boot, but it just went back to the boot loop again. Then, I thought to myself: I'll start it with the option key pressed and repair the os, but there was no recovery disk present at the 'boot choice' screen. It started to boot, but in the end it came back to the boot loop again.

I'm not a newbie to mac issues, so I tried to restart normally after long pressing the power buttom. So, I bought a generic usb to ethernet dongle to try and fix the problem, but after installing the driver for it, my macbook began to restart and show the (in)famous boot loop (your computer has restarted because of a problem,etc etc). The thing is: My wifi simply stopped working, there was no way to make it active anymore, so I bought a new airport card and installed it, unsuccessfully. I have thoroughly searched the internet about this problem, and also here over the posts, but can't seem to find the answer to my problem.
