Schmitz BusyMac has released [1]BusyCal 1.6.4, which lands just two days after the release of version 1.6.3. That update provided support for the Gatekeeper security feature in OS X 10.8 Mountain Lion, as well as a few minor fixes (a dock icon redraw bug on the MacBook Pro with Retina Display and a 403 error when syncing an iCloud WebDAV calendar). It also added support for the Daylite CalDAV server. Version 1.6.4 was quickly released to fix a bug related to code signing for Gatekeeper that caused some installation errors.
