Thanks for the link but since that posting i Have

  • Installed the release version of Yosemite on the internal drive
  • Discovered that Huey Pro has been abandoned and I removed it from the system
  • Searching for a new screen color calibration tool

Since making the changes I have had no further morning hangs and I have been able to disconnect the wired mouse that was preventing the "lost cursor" problems.

In fact the release version of Yosemite has been remarkably trouble free. That may be because of all the software updates and upgrades I made to get the Yosemite beta running smoothly, but so far the only significant issue I have had is with a few Java applications (installers and printer configuration tools) that refused to recognize Java 8 update 25, the version that is compatible with Yosemite, and keep insisting on wanting to install Java 6. I finally solved that by installing the Java Development Kit which the problematic Java applications recognized. confused That solution was pure luck and not because of any particular knowledge on my part.

If we knew what it was we were doing, it wouldn't be called research, would it?
