Mac OS X v10.6.3 Update

This is my first experience with major OS upgrade. I must say it went pretty smoothly on Mac. Update includes long list of security updates and many general operating system fixes and improvements.

General operating system updates (I am crossing out the ones that could not really make any different for me):
    •    performance of Logic Pro 9 and Main Stage 2 when running in 64-bit mode.
    •    printing reliability (nothing to report here, my printer got updates from Brother anyway).
    •    sleep and wake reliability when using Bonjour wake on demand (I haven't experienced any problems).
    •    a color issue in iMovie with HD content.
    •    glowing, stuck, or dark pixels when viewing video from the iMac (Late 2009) built-in iSight camera.
    •    an issue in which the Finder reports a -36 error when copying directories to a drive formatted as FAT32.
    •    reliability of photo screen savers.
    •    compatibility issues with OpenGL-based applications.
    •    an issue in which shadows in PDF of Aperture book are black instead of gray.
    •    an issue in which the microphone level in iChat may not increase the volume after reducing it to prevent a feedback event.
    •    the reliability of certain third-party USB devices (the only one which actually cause problems turned to be defective and I got it replaced by manufacturer).
    •    the Accounts preference pane can now limit login to members of groups hosted by a non-Apple directory service, such as Active Directory.
    •    DNS server ordering as specified in Network Preferences and DNS reliability.
    •    the reliability and compatibility of QuickTime X ( I am actually using it a lot so hopefully it got better).
    •    Data Collection: Mac OS X v10.6.3 can collect diagnostic and usage information from your Mac and send it to Apple for analysis automatically.
