Sims 4 Mods not working on external drive (Mac)

So I’ve recently bought a 2TB external hard drive to move my games to from my MacBook. My game runs fine on the drive, but anytime I try to re-add my mods to the mods folder it gives me a message that they are corrupt. It will literally do it with any mod or cc I add to the folder so I know it’s not specific to any one mod.

I’ve redownloaded them to make sure they were updated to the newest patches and still have the same issue. I’ve deleted the mods folder and tried to add to the newly created one. Still the same issue. I’ve repaired my game. Same issue. It’s getting frustrating. Any fixes for this? 

the message reads

“Cannot start because the below file appears to be corrupted. If this file is a Mod please remove it and try again. If not, please repair or reinstall the game via Origin.
