Unity build forces whole iCloud drive to reupload

I am using iCloud drive for my desktop.
When I make an iOS build, or recently also an Android build, even in a .nosync folder, my Macbook has a 30% chance that it immediately uploads the complete desktop (200GB) into the iCloud drive again. Then, my computer is virtually unusable for 2 – 3 days, because when I change anything, it starts from the beginning. Every file and folder gets an upload icon, and the iCloud info panel says “preparing files for upload”, while counting to 500.000 (number of files) for 2 days, and then one day to decrease this number again. It is incredibly frustrating, any help is appreciated.

From what I’ve seen, Unity/Unity projects should not be used on cloud synced drives.

You mean the cause for the iCloud hiccup is in the project files, Temp or such a folder? That could be, I will try that. I wonder how other people using iCloud handle their Unity projects.

No I’m saying you shouldn’t use Unity projects on a cloud synced drive at all.

Use it on a local drive. Use source control with a remote upload repro to push your changes to, so you can pull said changes from other devices.
