If you have the Night Eye app installed on your macOS 11 or higher, but still don’t see it in the extensions list, read further.
There is an issue with freshly installed Safari Extensions. We did our best to communicate it with Apple but they still haven’t fixed the problem.
Until they resolve the bug, there are 2 easy solutions.
Before going through the solutions, please make sure that your macOS is up to date. If you are going to update it now, please make sure to restart it before proceeding further.
It works on macOS 10.15, macOS 11, and macOS 12 and later.
The first solution is by installing the Safari Technology Preview, which will refresh the Safari extension list and the “Night Eye” extension will appear in the list of extensions.
The other solution would be to run a specific code in your Terminal. That will refresh all the installed Safari extensions and solve the problem with hidden Safari Extensions.
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
The extensions will be reindexed and shown again on the panel.
