As reported by HMBT, the forthcoming update Mac OS X 10.5.6 should fix 103 bugs currently present in Mac OS X. This would include miscellaneous graphics corruption issues, issues with DVI and display recognition, poor syncing services, printing PDF from Mail, and several MobileMe syncing problems. Of course, most of those bugs are not directly affecting most users or linked to specific applications.
This update should be made available for download in couple of weeks.
