How to reinstall system apps How can I reinstall some system apps?

There could be different reasons for that:


I've removed some of my system apps and now I regret (actually not).
Before I brought my computer to service center to replace corrupted memory it caused erratical disc writes which not only damaged some documents that I worked on but also corrupted some system apps (the part about documents is true).
I've found how to reinstall some of them.


Mount or your installation media.
You may have hidden BaseSystem.dmg in your installation media (for me it's in root).
Copy that BaseSystem.dmg somewhere and mount it to. It may contain Safari and Utilities:





Now you can just drag them in /Applications if you need them
