OS X desktop client app not starting

Can´t start app client anymore. After double click on app icon nothing happens.
Had anyone experienced the same issue? Does anyone know a solution?

Operating system: OSX El Capitan 10.11.1
Client version: 2.5.4 (build 11456)

I´m grateful for any advice!


is there a reason that you are on 10.11.1?

Hi, no special reason, it´s just the version I´m working on.

Then you should update :slight_smile:

The latest version I can update to is 10.11.6. I thought it made no big difference. I´ll give it a try though. :slight_smile:

Same here. Running OSX 10.11.6 (the latest my machine can support).
I rebooted the machine to no avail.
It is definitely not working.

An update:

Deleting the app (drag to trash bin), and then installing the previous version ( restored the function. However if I do the same with the latest version ( it will not run.

When the client is running properly, (2.5.3), then these are the processes running:

505 1015 1 0 2:53pm ?? 0:01.00 /Applications/owncloud.app/Contents/PlugIns/FinderSyncExt.appex/Contents/MacOS/FinderSyncExt
505 1030 1 0 2:53pm ?? 0:01.82 /Applications/owncloud.app/Contents/MacOS/owncloud

However when the latest version (2.5.4) is run, only one of the processes run:

505 974 1 0 2:51pm ?? 0:00.35 /Applications/owncloud.app/Contents/PlugIns/FinderSyncExt.appex/Contents/MacOS/FinderSyncExt

Yep! 2.5.3 (build 11290) works. Thanks for the tip!

We’re working on a version that supports 10.11. See https://github.com/owncloud/client/issues/7106


I am having the same issue on MAC OS X Yosemite 10.10.5 How do i fix it urgently, as I am not connecting to our shared work folders, which create a lot of conflicts once re-connection happens.


i think the question is if 10.10 will be ever be supported again? It seems they are only working on a version that supports 10.11. again:

Maybe you can also ask for support of 10.10 in that issue as well?

10.10 and 10.11 should be more or less the same in this case.

It was the same for me (OS X 10.11.6).
But this new build works.
Thank you
