I keep trying to download apps onto my MacBook. specifically, at the moment I am trying to download outlook however, every time I download it it says "null) can’t be installed on “Macintosh HD” because macOS version 10.14 or later is required." but when I go to the updates screen on my App Store it says I have no updates! Help I am so confused. This was my roommates MacBook and he gifted it to me.
