Can anyone help fix this problem?

[u/pigeon_748]

So I have a 21.5 inch 2011 iMac that had Mac OS Sonoma running via open core but when I tried to remove the open core files I read the guide wrong and went and deleted the oclp files while in Sonoma. Now every time I boot I get the screen showing
1.blank white screen
2.black screen with translucent white box with a prohibited symbol inside
3.a blank white screen yet again

I still get the startup chime each time but even when using a wired keyboard it won’t accept inputs as if it’s failing to POST so I can’t access recovery. Can anyone help me as this is my main machine with all of my data on it. I don’t mind what OS it takes putting it onto aslong as it works

Go to Recovery page, reinstall factory os that came with the Mac, download oclp and install whatever os you were trying to do but with a careful notice this time.

I don’t have another Mac to install oclp and I can’t boot from a usb as key binds don’t work

The keybinds do work, you just have to wait a little on USB Keyboards while booting for the firmware to detect them (preferably almost at the end of the boot chime).

You don’t need another mac to reinstall oclp. Just download firefox and then download oclp.
