Hey, I've had this plugin for a while but I can't open it in any way on my new laptop. I tried all the other troubleshooting suggestions mentioned on this forum but none of them work. Any ideas?

I usually use 2025 after effects but downloaded 2024 because that's the latest version it supports. I'm getting all sorts of error messages. Please help 

What have you tried? Have you gotten any warnings about an "unknown developer" and added an exception for PixDither in particular?

I think all the warnings I've gotten were the ones I attached. I tried all the techniques mentioned - making sure it's fully unzipped, right clicking and pressing open but I still into the same problem. I saw someone commented saying theirs got sorted by going to system preferences--> security and making a plugin exception but I can't find which buttons to press.

I haven't tried anything to do with Terminal if that's the solution

I sorted it! when the error message popped up I had to go to system settings - privacy&security, scroll down and allow the plugin. Then restart Ae and press Open anyway. thank god! thanks

Glad you could resolve the issue!
