Audio Driver Not Connected & Internal Sound Card - DJM T1 w/ 2x CDJ-1000MK3

I was able to use Traktor Scratch Pro 2 with my DJM-T1 & 2x CDJ-1000MK3, when my Mac was High Sierra. After updating my OS to macOS Mojave 10.14.6 and resetting to factory settings, now I can't get my set to establish a good communication with Traktor. 

I have the latest midi mapping file, and the latest firmwares | DJM-T1 - v3.0 | CDJ-1000MK3 - v2.3

My Traktor software version is 2.11.3. 

Also, I was able to get the DJM-T1 driver 1.2.0 (bypassed the security). Plus, I got the scratch control discs within the CDJs. (Everything should be working 

What I observe is there is somewhat a connection between the DJM-T1 and Traktor, I can choose songs and upload, and I can only use that squared pause button to play. However, no communication from decks and audio device is shown as not connected. A reddit post is relating this to the internal sound card.

Is this why my CDJ are not able to communicate with the software as the internal sound card is not utilised? Therefore, limiting the capacity of DJM-T1 (where I can only upload tracks and play from mixer)? Hence, the audio device not connected error? 

Because I believe I got everything right. Please enlighten me on this matter. Any help and advice is much appreciated.
