As I read on another forum, and a voiced opinion with which I agree with, "I don't want to rent my software. "It's that simple.
Yesterday I just upgraded to OSX Mavericks, and I read the User Agreement with interest. There was something new there that I don't recall reading before, in the
transfers section. I downloaded it from here:
http://www.apple.com/legal/sla/ (really nicely organized site!)
Here is the link to the license agreement:
http://www.apple.com/legal/sla/docs/OSX109.pdf
The interesting part that is new (to me):
"3.B.
If you obtained your license to the Apple Software from the Mac App Store, it is not
transferable. If you sell your Apple-branded hardware to a third party, you must remove the
Apple Software from the Apple-branded hardware before doing so, and you may restore your
system to the version of the Apple operating system software that originally came with your
Apple hardware (the “Original Apple OS”

and permanently transfer the Original Apple OS
together with your Apple hardware, provided that: (i) the transfer must include all of the Original
Apple OS, including all its component parts, printed materials and its license; (ii) you do not
retain any copies of the Original Apple OS, full or partial, including copies stored on a computer
or other storage device; and (iii) the party receiving the Original Apple OS reads and agrees to
accept the terms and conditions of the Original Apple OS license."
I find this very odd. But on the plus side, the usage terms are about a generous as anything I've ever seen....considering that the software is free
"..., you are granted a limited, non-transferable, non-exclusive license:
(i) to download, install,
use and run for personal, non-commercial use, one (1) copy of
the Apple Software directly
on each Apple-branded computer running OS X Mountain
Lion, OS X Lion or OS X Snow Leopard (“Mac Computer”
that you own or control;
(ii) If you are a
commercial enterprise or educational institution, to download, install, use
and run one (1) copy of the Apple Software for use either: (a) by a single individual
on
each of the Mac Computer(s) that you own or control, or (b) by multiple individuals on a
single shared Mac Computer that you own or control.
For example, a single employee
may use the Apple Software on both the employee's desktop Mac Computer and laptop
Mac Computer, or multiple students may serially use the Apple Software on a single Mac
Computer located at a resource center or library; and
(iii) to install,
use and run up to two (2) additional copies or instances of the Apple
Software
within virtual operating system environments on each Mac Computer you own
or control that is already running the Apple Software, for purposes of: (a) software
development; (b) testing during software development; (c) using OS X Server; or (d)
personal, non-commercial use."
