Script seems to be broken on Big Sur

[Piipperi]

Most if not all apps just give me this error. I've granted all permissions to Terminal from System Preferences and tried running script in sudo manually.

Using macOS 11.1 (20C5061b) on a MacBook Pro 15" Late 2013 w/RX 5700 XT

For me it was a matter of toggling the checkbox in the Preferences > Security and Privacy > Accessibility and enabling Terminal (as per README.md).

Same problem for me, terminal is however allowed in Security and Privacy

Same here.

The script is able to open the properties, but the box does not get checked.

I have the same issue. macOS 11.4 (20F5046g). Terminal is allowed all permissions but script does not enable preference towards external GPUs in any application.

Same here. I am looking at the script lest see if I can find anything.
Checked and my accessibility preferences had reverted that is all, working fine now.

I suggest you check preferences.
