I'd like to solve this but don't know where to begin. As it stands now, I'm seeing this error very frequently on MacOS 10.14.6, running my self-made .app package based on a PR I made from git master. After setting loglevel debug on deluged, this is the error I get: {{{ 17:55:41.697 [DEBUG ][deluge.core.alertmanager :1418] Handling alert: session_stats_alert 17:55:41.697 [DEBUG ][deluge.core.alertmanager :1418] file_error_alert: Wolfwalkers.2020.HDR.2160p.WEB.h265-KOGi file_open (/Volumes/Movies/Wolfwalkers.2020.HDR.2160p.WEB.h265-KOGi/Sample/wolfwalkers.2020.hdr.2160p.web.h265-kogi.sample.mkv) error: Operation not supported }}} This error then repeats multiple times and the torrent is paused and set to error. I can put some time and effort into helping fix this but as I said, I don't know where to begin." bug new critical needs verified Unknown master macos, error, file, download
