OpenCore Legacy Patcher: Ventura Crashing / Slow? iMac(2009&2015)

[WaffleMXM]

Hello everyone,
Has anyone experienced an issue installing Ventura with OpenCore?

I’m using a Late 2015 iMac - after installing Ventura it boots but it looks as if it boots safe mode? The start button has a black background like in safe mode.
If I try to press start at the hello screen - I get a big graphical glitch and then the computer reloads - goes back to the hello screen.

I tried bypassing by booting this drive on my 2015 MacBook (works fine there) I did the setup process.

Plugging back to the iMac - let me log in - then the whole computer freeze’s completely.

I just tried installing it on my 2009 iMac to see if it would run - similar issues. Instead of crashing it just runs at 1 fps - setup takes forever. Mouse scrolling takes ages. Same iMac runs Monterey great.

However it works and runs amazingly on my 2015 13” MacBook Pro?

Is there some kind of an issue with Ventura through OpenCore with macs that use dedicated graphics?

Would welcome any input on this.

running great and trouble free on my late 2015 21.5 iMac. I'm on 13.2.1 I think. staying away from 13.3 from what I read.

Ventura 13.3 running ok on late 2013 MBP. However not so good on my cloned USB SSD backup. It booted ok on first boot. Then I applied the OCL Patch and now the boot gets so far and then comes to a grinding halt. It used to work fine so I’m thinking that 13.3 has done something nasty!

I have been stuck in the progress bar after installing it with no luck.
the verbose mode shows it gets stuck at dlil_init

iMac 21.5" late 2009

I will try 13.2.1 tomorrow, any other ideas?
