Hi - have been using PortingKit to install SE versions but since (I think) upgrading from Mac OS 12.0 to 12.1 I can't seem to install new games.

Monkey Island SE 2 gives the following error in the log:
0024:err:winediag:wined3d_dll_init Setting multithreaded command stream to 0x1.

Games (eg Monkey Island SE 1) installed under Mac OS 12.0 run fine after the upgrade, I just can't seem to install new ones.

Any ideas?

Fixed! The previously installed games were running under wine engine 20.0.4. The newly installed games were using 21.1.0. Using wineskin to change the engine from 21.1.0 -> 20.0.4 fixed the issue.
