FinderSync appex not installed

Question

I have an application that implements a FinderSync app extension. The problem is that on a customer computer, it seems that FinderSync is installed only after Finder is restarted, but not before. The customer has osx El Capitan(10.11.2).

I have a screenshot from that customer with the application running, but finder extension not installed in System Preferences->Extensions I also have a log file where I logged the output of the following command:

pluginkit -m -A -i com.xxx.xxx.xxx -v

which returns

(no matches)

The thing is that this happens only on that machine, all other machines we are testing on are working fine: the extension is loaded immediately after the application is opened.

Do you know why Finder does not load the appex immediately after application is running? Is there a way to avoid this behavior?

Thanks!

Answer 1

You got to look in the System.log file for plugin com.xxx.xxx.xxx invalidated .

If you see that, it means that the system has kicked out your plugin. You can just re-add then.

I'm currently looking into why mine get's invalidated.
