Skype didn't need permissions to install?

[Schtibbie]

Just curious - why, when installing Skype, did Mac OS not require me to put my password in? Basically, a DMG file went to the desktop, which I clicked on and that opened a disk image as mounted. The disk image had me drag the Skype application to Applications folder, which is what installed Skype.

Is that sort of installation a non-password-requiring type due to its low impact or something?

Administrators have write access to /Applications, among other places.

Difference is now that the owner of Skype is set to <your_short_name>, and all other admins can read/write.
Normally the owner of an app is set to "system" and "admins" can read/write.

No real issue here.
