Getting rid of OpenCore.

I managed to install Sonoma on a iMac 2015 and it all worked fine... except VMware Fusion, which I really have to use on a daily basis.

So, I went back to Monterey. No big deal.

But... Somehow OpenCore is still on my iMac:

  • After the startup chimes, I get a menu for a few seconds and then Monterey boots up. It's kind of annoying, but I can live with that.

  • Thing is, I'm still receiving notifications to upgrade to Sonoma every time Apple releases a new version. Somehow, OpenCore persists.

Is there any way to get rid of this without reformatting the whole computer?

Any info would be appreciated.
