Steam not fully downloading game. Stuck at 86%
I've just resurrected steam on my intel macbook running Mojave. It has the 'steam will stop running in 0 days' message, just like on my imac which also runs mojave, but it is working. Now it's time to download some games! Unfortunately, no matter what game i try to download, it downloads up to 86%... and then it stops. It's like it doesn't even realize that it has more to download lol.
86% is such a strange number to get stuck at that I think it's gotta be something do with something like a checksum check. I've gotten all of my games to work on my imac before (now it's just updates that have this problem), I've tried to verify integrity of files (it says nothing is installed even though that's clearly not true)
i've tried copying all files over from my imac for a game (it said 'cannot find game'), i've tried deleting the steam download cache 3 times (same result), i've even tried booting in safe mode and then restarting the download (same result).
It even still randomly starts trying to download the game again automatically, but doesn't get anywhere past 86% and 348.7 MB.
Any ideas?
Edit: the goal is to not upgrade macos. I have 32-bit plugins i use that I need mojave to keep running. my games were working on my imac (which again, runs mojave) just a couple months ago and as long as i don't update them, they would most likely run today if i booted them up. we humans have put a man on the moon. i believe that we can solve this annoying little issue.
