I installed Nextcloud-2.5.2.20190319.pkg and then opened /Applications/nextcloud.app. I can see in Activity Monitor that a nextcloud process is started, but it doesn’t seem to do anything. No window is opened and no icon appears in the upper right to indicate that Nextcloud is active. I can only kill the process.
I also tried starting with logging options: /Applications/nextcloud.app/Contents/MacOS/nextcloud --logdebug --logfile ~/nclog/nc.log --logflush
Still, nothing happens and no log file is created. Does anyone know how I can determine the problem?
I am including details. Please let me know if I can supply any other information.
System information
Nextcloud open files and ports
Nextcloud process sample
I should mention that the nextcloudcmd command-line utility does seem to work fine. Synchronization completed successfully.
UPDATE:
I made some progress by starting MacOS in Safe Mode and installing and configuring Nextcloud as usual. Then, I restarted in normal mode. This time, the nextcloud process was unresponsive for maybe 30 seconds after Dropbox had started, but then the icon appeared as usual. Everything was fine.
However, it is back to the original problem on subsequent restarts. The process is there, using a small amount of memory and no CPU. No icon appears.
There must be a conflict with something else that gets started during a normal login. However, it’s a pretty fresh installation of MacOS. I installed Dropbox and not much else. I tried disabling Dropbox and iTunes Helper, leaving only Nextcloud as a login item. There was no change.
