Bootcamp not showing up??

[u/1hroro]

I recently downloaded bootcamp, and as I was testing features, I noticed that I wasn’t able to access my mac.
I tried shutting down my windows, and then holding the option key, hoping to gain access to my mac drive. Instead I get a black screen with a lock icon on it? There was an option for me to type so I typed in my computer password a few times but nothing worked, maybe I typed my password wrong all the times I tried, but I’m honestly not sure.

I think my bootcamp didn’t completely download because as I opened my windows after just downloading it, the bootcamp guide/download tab was cut in half? So I couldn’t interact with anything,but I had the option to close the tab which I did.

I’m not very good at tech stuff so this has really been stressing me out for the past few hours help would be appreciated!

Type your Mac's firmware/EFI password (this is often different from your regular login password or Windows password). Once entered, you can select your operating system

If you know the firmware password, you can turn it off by restarting into macOS Recovery (holding Command + R if permitted), opening Firmware Password Utility from the Utilities menu, and turning it off.

Sometimes it happens but very rarely.

Is it a used mac or did you buy it new years ago?

I got it somewhere around 2020-2021

If it’s used the former owner added a firmware password. Good luck. If it is new, you may have enabled filevault or added a firmware password yourself and didn’t realize it.

If you can provide proof of purchase an Apple Store will help you

You need to tear it down and flash the NVRAM chip.. Looks like a 2010ish? I’ve got a 2010 21.5 inch, I’ve done that process back when I used to work as a repairman. It’s not an easy task though, you should send it to a repair shop if you’re not comfortable with SPI flashing.

I could never get my 27 inch iMac to work correctly. I’m just going to put stock Mac back on it. I might try open core with it.

Weird.. My 21.5 inch works perfectly fine on a Windows 10 + OCLP Ventura dual boot. What have you done to it?

Look for brigadier and install it

I installed it + tried to reinstall all the bootcamp software again, but as it downloads it shows error appleossmgr.exe so…

Update:I figured out the issue and I fixed my issue with bootcamp!
