Finder Extension on macOS 15 Sequoia

[aonez]

Seems Finder Extensions are no more on upcoming macOS 15 Sequoia, at least on the first beta.

Posted on https://forums.developer.apple.com/forums/thread/756683 to see if anyone else can confirm.

Workaround for macOS 15.0 - 15.1

There is a fix implemented in the Keka Helper v1.2.0 since Keka v1.4.4:

Can confirm, its no longer there.

Yep, I cannot enable nor see Keka in extensions.

There's a simple workaround for now. Simply run pluginkit -mAD -p com.apple.FinderSync -vvv which produces an output similar to:

     com.aone.keka.KekaFinderIntegration(1.4.3)
	            Path = /Applications/Keka.app/Contents/PlugIns/KekaFinderIntegration.appex
	            UUID = AB3031DB-D94B-44D0-AD58-EA935ACEA96C
	       Timestamp = 2024-08-10 21:36:21 +0000
	             SDK = com.apple.FinderSync
	   Parent Bundle = /Applications/Keka.app
	    Display Name = Keka Finder Integration
	      Short Name = Keka Finder Integration
	     Parent Name = Keka
	        Platform = macOS

Then you can run pluginkit -e "use" -u "AB3031DB-D94B-44D0-AD58-EA935ACEA96C" to enable the extension.

Thanks @JoshuaFern, this workaround will be implemented using the Keka Helper in the next revision.

[gingerbeardman]

There's an app for that.

Sorry I did not informed here that this is implemented in the Keka Helper v1.2.0 since Keka v1.4.4:

@gingerbeardman, I'll be free to add that FinderSyncer should not really be the solution, but a temporary workaround instead. I'm afraid that everything happening with Finder Sync settings in recent versions of System Settings application is a sign of slow deprecation and discontinuation of Finder Sync extensions, especially as Apple pushes File Provider API for "applications which synchronize the contents of a local folder with a remote data source". And they claim that was the initial use case for Finder Sync extensions.

I'd urge @aonez and all other developers distributing Finder Sync extensions to read discussion on this thread on Apple Devs forums (after all, that thread was spawn off of another one created by @aonez himself, this one), chime in and (try to) let Apple folks know that if they deprecate Finder Sync extensions, whey will break a lot of third party applications. I have no illusion Apple would be very stressed about it, they keep doing whatever they want for the past 8 - 10 years anyway, but at least we can try.

[gingerbeardman]

Of course.

Next version of Keka will use the proper way to activate the extension in Sequoia if macOS 15.2 or later or macOS 14.* or older.

v1.4.7 can be activated again in the Sequoia Settings. The workaround is only enabled for 15.0-15.1.x.
