problem with update
hello,
I just bought a new, unopened MacBook Air 7.2 in Zagreb, Croatia. It should have highSierra OS but it came with Catalina. Is this even possible, or has somebody used this device before and now sold it to me? I'm asking this because I can't update my Pages app due to an error "Pages cannot be updated because it was refunded or purchased with a different Apple ID." ??? I haven't had any apple ID's before.
hope you can help.
MacBook Air 13″, macOS 10.15
