Yeh I ain't ever heard of Intellect either. Could have been an alias or word KMack was using back them ... sort of like Q-Tip the Abstract.
In case you don't already have them:
Concrete (he's the most active on IG): www.instagram.com/djconcrete
Silouette: www.instagram.com/a.k.a_silo
KMack: www.instagram.com/kmack_knok_annexx
Also, 90s Tapes out of Berlin re-released a K-Mack record a few years back. They're pretty responsive on socials and they always interact a lot with artists they release, so could be a random string to pull,
"Though what i find interesting is how it says "K-Mack, Intellect and Silouette" and i cant find any trace of said "Intellect" related to the group
