Downloaded Beta 1 from the link Richard posted http://downloads.logos.com/LBS4/LBS4MacInstallerBeta/Logos4Mac.dmg
L4 immediately began downloading 11MB of new resources. The application hung at 65% even though I allowed ti to download overnight. Quit L4 and rebooted the Mac. When L4 finally started, it began downloading 8.4MB of resource updates which hung at 8%. After Activity Monitor showed no activity for 5 minutes, cancelled the download.

At the time of the log, Beta 1 is still running and appears to have no additional problems now that the download is terminated.
