We are sad to announce that, as of now, desktop version of Coloban is not supported on the new ARM based Apple computers.
Versions for other platforms are still working fine and iOS arm version is working fine as well: https://www.coloban.com/download
We are currently working on bringing that compatibility to life, but that most likely would just happen closer to December…
In the mean time, if you are a happy owner of that new fancy device we are really happy for you 
You can still use Coloban in your web-browser just fine and access all your chats or Tasks in there.
Cheers,
Coloban team.
