I would jump into the KDE Connect Matrix room: go.kde.org/matrix/#/#kdeconnect:kde.org and the KDE Mac room: go.kde.org/matrix/#/#KDE-Mac:kde.org to discuss. Builds are now done on GitLab directly, but it may be the case that nobody has set up the CI builds.
Thanks mate! Looking at KDE Mac room it looks very dead now. Strange, I thought that people would also be interested in getting some kind of sync between their phones and their Macs. I’ll see if I can do something, but I’m far from being a developer…
