I am experiencing a critical issue with the Nextcloud desktop client on my MacBook Pro with Apple Silicon (M1). I have installed the latest/appropriate version of the client.
After installation, the “Nextcloud” location appears in my Finder sidebar. However, it persistently shows the status “Nextcloud is signed out” and “Loading…”.
When I click the “Sign In…” button, a blank white modal window appears and the Finder application completely freezes (hangs). I am unable to interact with Finder and must force quit it using “Force Quit” to regain control of my computer.
This makes it impossible to set up or use the Nextcloud desktop client with Virtual Files.
Here is what I have already tried:
I have reinstalled the Nextcloud desktop client.
I have confirmed I am using the -arm64.dmg version for Apple Silicon.
My Environment:
Device: MacBook Pro (Apple Silicon M1)
macOS Version: (e.g., Sonoma 14.0 - please add your version here)
Nextcloud Desktop Client Version: (e.g., 3.11.2 - please add the version you installed here)
Nextcloud Server Version: (e.g., 27.1.5 - please add your server version here)
I have attached two screenshots that illustrate the problem:

Screenshot 2025-09-13 at 13.55.56.png: Shows the blank modal window that appears and causes the freeze.
Could you please advise on how to resolve this issue? Please let me know if you require any log files from my system to help diagnose the problem.
You may find a solution by reading the comments under GitHub Issues. My personal recommendation is to refrain from using VFS support for the macOS client for the time being. I have the impression that the feature is not yet stable enough.
=> But that’s just my personal impression.
If you see an existing issue on GitHub that describes your problem exactly, then I recommend giving it a thumbs up. This allows developers to better assess the severity of the problem. But please as a reaction and not as a comment, so that there is no spam.
The empty modal view rendered by Finder is a system call our file provider UI extension did not implement yet. I have done so in a feature branch already and it is intended to be part of the next 3.18 release.
Please note that the missing user interface implementation is unrelated to any synchronization or authentication problems which also were taken care of.
