Looks like my 2012 iMac will end with Monterey then. Ah well, it's been a good run. 🙂
The OCLP developers have announced on GitHub (posted here many times now) that we will have to wait about 6 months to see if there may be a possible solution via OCLP. So, we won’t know for some time about ivy bridge macs from 2012.
If the goal of this thread is to help get Ventura running on legacy macs and spread helpful information, the above comment is cute, but also is neither healthy nor helpful speculation. It is probably best just to wait and check in here or GitHub from time to time over the next 6 months to see if any solution emerges via OCLP or another source. It is also entirely possible that a solution will emerge after a full year has passed. Remember how long it took to get graphics acceleration on pre-2012 macs for Big Sur? It took quite some time—more than 9 months from the first public beta, if memory serves me correct. So all of these comments are quite premature and short-sighted. If you look at the history of macOS on unsupported machines, you will see that solutions emerge sometimes a full year or years after a release. I would wager that after a year, some kind of solution will have emerged for Ventura.
You can read for yourself here about OCLP’s best guess:

N.B.:
It might be a good idea to post this blurb below from GitHub clearly in the first post of this thread. That may help reduce the “are we there yet? Are we there yet?” posts and the “goodbye, my beloved 2012 Mac“ posts.
Overall estimate time for support
Looking at all the issues in front of us, I don't believe there's any short term possible fixes for the commuity to use. Best time frame would be 6 months from now when a proper build of OpenCore Legacy Patcher can be released, but even this is difficult to promise.
