Uz ma dost dlho sere odklikavanie ze nechcem updatovat "Pro Applications Update" z istych dovodov ;)

Metoda pre unixakov:
Try using the command "softwareupdate --ignore" in terminal. You can first start with a "softwareupdate -l" to get the actual names of the updates (usually something like iPhoto-9.1...) and then use the ignore command to stop them from showing up.

To see everything that binary can do, try running "man softwareupdate".

Metoda pre klikacov:
Just go up to the menu bar and hit Update>Ignore Update (or the keyboard shortcut is apparently just the delete key).
