Hi guys.
Finally, I installed Mojave on my Hack, thanks to Olaria Site.
Everything work fine - dual monitors on Intel Internal Video, external Firewire Apogee Duet card, sleep, shut down - everything OK.
2 small issues which I believe could be corrected.
1) I've got 27" LG 4K monitor, but system shows 30" UHD monitor instead. Second monitor (Apple Cinema Display) shows correctly.
2) When I increase or decrease volume using Microsoft multimedia keyboard, slider at the top navigation system ribbon does not moving at whole, while poping up volume control at the middle of screen works correctly.
I had to split SEND ME file into 2 archives, cause can not send it as one file. These 2 archives from 1 folder, created with RunMeApp.
Thanks for your help.
