Hey guys I installed clover by mistake and I can reboot the computer and everything works normally, but I don't want to brick it.

How do I fix the EFI partition?

I would really appreciate your help guys!

Use this to mount the EFI then remove the Clover, Clover install log and Boot folders.
EFI Mounter v3.1

Thank you very much for helping me, I really really appreciate your help ...

These are the folders that I have, please take a look at the screenshots. They look a little different than "boot" and "clover", I also have "boot.app" as a file, "EFIROOTDIR" as a symlink or shortcut, EFI-backups ..

Thanks again, I'm very nervous I don't want to make another mistake... :(

Hello All
I have an MBP 15 Early 2011, its was working fine and now when I power on it gives repeated boot chimes. I tried SMC reset and PRAM reset (but my left control and left **** didn't work earlier) so not sure if they worked.
Also, sometimes it just boots and no chimes and nothing on screen.

What could be wrong ?

As early 2011 have issue with the AMD GPU, I am using regular method of using nvram var and removing AMD kext to only use intel GPU

Did you use or install Clover to this MBP ?
Well I didn't but I had issues booting earlier and then had to do boot linux and remove AMD GPU NVRAM Variable.
When I did ls on the /sys/firmware/efi/efivars. I saw opencore variable. But then it was working fine without any issues
When I was troubleshooting issues I did face boot chime repeat issue but was resolved (not sure how). I was trying multiple things. Way earlier I did try to boot via an OpenCore USB stick.

Code:

AFAIK OpenCore doesn't create any problems with real Macs the way that Clover does. It's probably best that you try posting in another online forum that is MBP specific for these kinds of booting problems. None of the problems you have are Clover or OC related.

If anyone is wondering, I followed the instructions from the site GhostlyHaks how to reflash the EFI chip.

GhostlyHaks also provides clean firmware files, but be careful as the one for this machine was not cleaned, so you have to replace the serial AND the Intel ME Region on your own. The latter is quite hard to get right. (And almost impossible to get right without the corrupted dump)

I also tried to do the same on another 2015 13" MacBook Pro, but it had a different chip on which the POMONA clip won't work, so the only alternative was the EasyFlash 4.0.3 adapter (also from GH) BUT it COULD destroy the 2015 13" MacBook Pro which is stated clearly on the site. As it was the only option apart from buying a new Logic Board, I bought one and tried it. It did however destroy the Logic Board (no charger light, completely dead) and now I have to buy a new one.
Don't blame GH for the dead Logic Board, I was fully aware of the risk.

Also why does writing a reply lock up the site every 30 seconds for about 10 seconds? Really annoying. (Android 7.1.1, OnePlus 3, Chrome 60.0)
Hi! Check CheckM8 EFI firmware removal tool - the CheckM8 tool provides a quick solution to remove Mac EFI security firmware (BIOS) password protection and disable secure boot for all Apple Mac computers with a T2 security chip. Also on this site, you can find the bypass activation Lock tool for Mac T2 device!
