Sorry for the late reply. My system was unstable on High Sierra likely due to the graphics card I had. Constant freezes, regardless of what I did to configure it. So I just stayed with El Capitan until I was willing to switch video cards.
I just install received and installed the Fenvi FV-T919. Worked out-of-the-box and now I have better Bluetooth, native wifi, air drop, and I can login to my system using my Apple watch. Definitely recommended!
I wanted to upgrade to Mojave because I bought my wife a new Mac Mini and was so impressed with the new bells and whistles. Also, I needed to update my system to support Docker for Mac. So I solve all problems and one fair swoop.
