Hello,
the ThinLinc client for macOS is currently supplied as an intel-only build.
Starting with macOS 26.4 (due to release in the next couple of weeks), macOS will start displaying notifications informing users that “this application might not work on a future release of macOS”, requiring acknowledgement before launching the application.
Apple Support already has updated their documentation in preparation of this.
Rosetta is currently announced to be available through macOS 27, and will no longer be available starting with macOS 28 in late 2027; however, the popups will start soon.
Is there a timeline for either a universal build, comprising both intel and Apple Silicon binaries, or a dedicated Apple Silicon build ?
Thanks in advance for any information you can share !
