Newton2 and macOS 10.5 Catalina fix

So, you have upgraded to the last version of macOS 10.5 Catalina. But suddenly when you launch After Effects you get that message that tells you that you cannot run Newton.

Now, the bad news:  support has been dropped for Newton2.
The good news, you can still use it with macOS 10.5 Catalina, here’s how!

→You can use aescripts manager to install it and register

→Or you can go to your security preferences into macOS to allow Newton2 to run it (more info here):

– You have to launch Adobe After Effects and macOS will say that Newton2 is not signed.
-Click cancel
-Go to your security preference.
-MacOS will ask you if you want to run Newton2.
-Click Open Anyway


Note that if you have the same message with Newton3, you just need to download and update to the last version.

Or you can upgrade Newton and get up-to-date features!
