FoCal 2.6 MR1 Key Features

New Features

  • Full macOS High Sierra Supporta huge amount of work has gone into the code which communicates with Canon cameras on macOS for this release. The communications libraries formally supplied by Canon are now totally re-written and replaced by Reikan developed code.


  • Minor bug fixes

Canon support on macOS High Sierra

This release is for Mac users only, and resolves the issue some users were seeing when connecting Canon cameras on macOS High Sierra computers.

We’ve completely re-written the underlying Canon supplied communication code. Removing the Canon code removes FoCal’s reliance on Canon libraries, we’re excited as this means an end to any mac/Canon issues that can happen after a new macOS release! FoCal’s communication to Canon cameras now works in a similar way to Nikon which has been historically more stable with less changes required after a new macOS release.

Replacing the 3rd party Canon communication libraries opens up some exciting possibilities and lays the foundation for some great updates to come over the course of future Reikan FoCal releases. Watch this space!
