Problem:
- All games in Battle.Net cannot be started. An Update button is shown instead of Start.
- Update process cannot be done. A message will be provided indicating a permission error.
- If you managed to reinstall the whole Battle.Net app, more problems about permission will occur.
Solution:
Go back to OSX 10.10.2 with your backup. Or, wait for Blizzard updating. No official statement made yet.
