I read about that there is a new client for MacOS:
I had the exakt same error with the cannot find status.php. So I downloaded the newest version Nextcloud_18.104.22.168.pkg and installed it. First it looks good the installation finishes without errors.
But the application crashes when I try to enter the server and hit the “Next” button.
OwnCloud App works fine so far without any problems.
