This morning I allowed Nextcloud Desktop Client 33.0.0 (Mac OS 26.3.1 (a) on an M2 MacBook) to install itself. Since then the client is not working. It shows this message ā€œSome files couldnā€™t be synced! see below for errorsā€. There are no errors showing below. The taskbar icon is `Xā€™. Restarting (first the computer, then the app itself) doesnā€™t change anything. ---

I found a red alarm message in the settings for the client that said the synchronization folder needed to be reauthorized (or something: I didnā€™t write it down), please click on the message. I did that, it brought up the folder in Finder, I said yes, open that, and it proceeded to synchronize. ---

It does work for Mac OS 26.3.1, but **it does not work for Mac OS 13.7.8** (Ventura). The Nextcloud application is not responding at all. I tried to reboot, reinstall, the combination of the two, but nothing works. And I could not find how to come back to previous version. ---

Exactly what I need to come back to 4.0.8 Thank you so much! ---

@Alyosha Please see my answer here: [Access on local file from the nexcloud apps - #2 by iva.horn](https://help.nextcloud.com/t/access-on-local-file-from-the-nexcloud-apps/242350/2) @Christophe_Giraud You are having a different problem: [33.0.0 Terminates on Launch on macOS 13 Ventura Ā· Issue #9694 Ā· nextcloud/desktop Ā· GitHub](https://github.com/nextcloud/desktop/issues/9694) ---

Thanks. I see that the issue is that the folder being synchronized needs to be re-authorized. Perhaps the client can notify the user that this is so. ---

Yes, we are aware of the insufficient communication and will release an improvement in the user experience and reauthorization process with the next maintenance release. šŸ˜¬ ---

@iva.horn Indeed, I have the problem you are pointed to. Thank you very much for your support. I have fixed the issue by removing the 33.0.0 version, reinstalling the 4.0.8 version and resynchronizing everything from scratch. And thank you again @Alyosha for providing the link, I did not manage to find it by myself on the Nextcloud website. It was very helpful. Good day to both of you ---

I need to go back to 4.0.8 too, but which of the 8 download files do I have to use for MacOS Tahoe 26.3.1 ?? ---

I have used this one [https://download.nextcloud.com/desktop/releases/Mac/Installer/Nextcloud-4.0.8.pkg](https://download.nextcloud.com/desktop/releases/Mac/Installer/Nextcloud-4.0.8.pkg) but I am under Ventura, and I did not try under Tahoe. ---

Thanks for this, the re-authorisation solution worked for me on macos 15.4. ---
