That's Great Clinter!
These were my findings I posted in another post:

Mojave Report (08/27/19)
Everything is working fine now in this Mac system configuration:
- iMac 27" 5K i7 (Late 2015) >with Thunderbolt 2
- Mojave (latest update) > fresh install
- DM-4800 with latest driver/firmwares (got them from the link bellow, thanks to Marvel!)
https://drive.google.com/drive/folders/1LkEvXayUtLQG7ms0Gmxf8O5IUH_40Gwc?usp=sharing
- FW400-to FW800 cable (from FW card)
- FW800-to-Thunderbolt 2 adapter (Apple original)
- Tested with PT HD 19.6, Cubase 10 Pro, OS system, etc.
Note: In my system the FW card was recognized when I installed the FW driver 1.30f10 (and approve the System Changes!!)
better explained by Clinter <<then went to the Security and Privacy tab in the system preferences. There was a notice on the General tab that I have never seen before. It said that a device driver for Teac Corp had not been loaded and there was a tab with the option to load it. After clicking on the tab to load the driver, suddenly High Sierra sees my FW card....and it works!>>
Note 2: The FW card Control Panel is NOT in the System Preferences but inside the Application folder (I totally forgot about it)
Nite 3: You can see the FW driver version opening the IFFWDMmkII Control Panel and selecting ABOUT in the Top (of the Computer Screen) Menu.
Hope this help somebody.
