macOS High Sierra (10.13) is out today, and we did not find any major compatibility problems with the latest version of Mitti, Vezér and CoGe VJ.
Here are some things you need to consider before you upgrade:
Installing High Sierra means you file system will be upgraded to the new high-performance 64-bit Apple File System - but some caution is warranted. Making a backup won't hurt.
Apple's new OS includes new security features that require the user to allow a system extension when installing a new driver. This is very simple and only needs to be done once for each driver. So, if you're installing any new driver on macOS High Sierra, look out for the following pop-up message and check out the driver section for instructions.
This is very well explained here.
Some ISF Filters and Generators (like ColorBars.fs) may render oddly on nVidia based Macs. This is a system bug, and we are waiting for Apple to fix it.
Unfortunately we were not able to test every possible hardware and software combinations.
