"You're running low on disk space"

Longer-term though, having only 13 GB free on your drive isn't good for performance or for the overall health of your computer.  The system uses some of this space for swapping data in and out of RAM under heavier loads, but that's only possible whenthere's enough space in the first place.  And installing a new OS version requires more space than that as well.  So it might be time to invest in a quality (and fast) external drive and move some applications there instead, perhaps including Sims 4.

same thing is happening to me and my brand new macbook. stops at 80% and says there isn’t enough space. same exact thing is also happening to my sister. i’ve purchased almost every pack you can and i have zero cc or mods !! i never have . this new update broke it 🙁 i cant play it.
