MT4 cannot add custom indicators after reinstallation.

 
Specifically the inability to paste.
1, the file properties are fine.
2, Indicator property is fine.
3, uninstalled and reinstalled, refreshed, shutdown and restarted all tried
4, macOS is the latest version, MT4 is the latest version.

No matter what, I can't get the paste to work, including Indicator's built-in files, and I can't copy and paste them either! Does anyone have a way to provide guidance to solve this specialized problem? Thank you very much!
