Hi,
I have 2 Exact MAC Pro 5,1 12 Cores 2.66 GTX680 4G
Waves Mercury, Izotope 7, Sound Toys V5, Mcdsp Emerald V6

One Has High Sierra, one Mojave.
Brand new Samsung EVO 860 SSD.

I started from Scratch, clean installs.
The High Sierra rig crashes:
Sometimes loading IZotope plugs
Removing waves plugin from and insert
Removing Automation from waves plug.

I don't think I want to update High Sierra Mac to Mojave, because I don't think I can boot into OSX 10.8.5 Drive and Run PT 10 ( need to do this is this room),
I tried holding option key on start on my home rig which is similar, wouldn't see 10.8.5 boot drive
Thanks!
