Hi,
I have noticed that under Sequoia (15.0) the Finder extension doesn’t work anymore. Whenever I click on "Activate Finder Extension" in BTT I’m seeing this. No trace of BTT anywhere in the other panes related to Extensions. Tried updating to alpha but seems like I’m already running the latest version 4.702.
Thank you,
Alex
You are right, apparently Apple hid Finder extensions in Sequoia for whatever reason.
You can still use it but it now requires a terminal command to enable it
(Finder Extension on macOS 15 Sequoia · Issue #1464 · aonez/Keka · GitHub )
First you need to run this to see all available Finder extensions:
pluginkit -mAD -p com.apple.FinderSync -vvv
Then you can enable it using this command (replace the UUID):
pluginkit -e "use" -u "CAFF7775-65BA-43D4-AF09-DFD3A04F7B72"
It seems like this doesn't require sudo or similar, so I think I can automatically run this when a user clicks the activate button!
In the latest build the "Activate BTT Finder Extension Button" will try to execute these commands to activate the extension.
I was not expecting you to reply so quickly given the macOS update 
I have just executed these and the BTT context menu I had created reappeared immediately.
I have come to hate macOS updates because Apple always break a few things and every time it takes me a few days to repair everything.
Anyway, thanks! Let me know if I can do anything else.
—Another happy BTT user
