No, T2 is only found on the 2020 model.

Try this one. Make sure you do PRAM reset.

Hi, I've tried this one and the iMac will not boot into an OS. It loads for a while then reboots.

Hi all! I have an iMac 2019 27" A2115 EFI locked. Pressing the option button during boot doesn't give me any options to boot from a usb stick. Just the apple logo.

I have attached the original bios file. Can someone unlock it? I've already tried 2 different bios files I found here and there but no luck so far. Thanks in advance guys!

Thank you for the response! Unfortunately it doesn't work. The apple logo is not showing up at all after flashing this file. Do you have any suggestions or a different version to try out?

I have a 27" imac 2019 model that is stuck on the apple logo. I'm not sure if this is the right approach but I accidentally had a usb containing a firmware.bin for my 3d printer, i'm wondering if it reset something? Otherwise I've been booting off my new 2tb external ssd and after installing a driver for it the restart brought me back to apple logo. I can't get back to recovery or anything to ensure I have the "allow boot from USB" but it's done it ok before. Any suggestions? I have another mac I could connect if needed.
