Hi there,
we are now trying to install Mac OS Catalina 10.15.5 on a Aorus Z390 Pro WIFI,
we tried several USB ports for the key boot and obtain different crashes... but new never access to the
real installation phase. Just get the first loading with the apple to initialise the installation,
never been as far as language selection before running the app.
It just load, then around the middle we get a cancel symbol OR a black screen then get back to the unibeast interface. depend of the USB port use.

We think it might be during the installation, the program loose the USB path and stop running?...

We tried safe mode, verbose ( but we didn't get the bug page on it ), we checked to unable USB ownership and USB injection in PCI device option... non of it worked

any ideas ?...
