Question

I own SL16.2.4

My friend just bought SL16.4.2AI

My friend wants to record stuff at his house and I want to know if my Macbook can serve both

I reseached and found the two UC are not the same

Answer 1

That would depend on your operating system. 16.4.2 compatibility stops at Mojave but the 16.4.2AI can go up to Big Sur.
