License
Snow Leopard is available as an upgrade for Intel-based Macintosh computers. Single-user licenses and "family pack" licenses for up to five computers are available. For qualifying Mac computers bought after June 8, 2009, Apple offered a discounted price through their "up to date" program provided that customers' orders were faxed or postmarked by December 26, 2009. The standalone retail version of Snow Leopard is marketed as being restricted to users of Mac OS X Leopard, while the recommended upgrade path from Apple for Mac OS X Tiger is through the "Mac Box Set", which includes Mac OS X Snow Leopard and the current versions of iLife and iWork.
There are three licenses available. These licenses differ in their requirements for pre-installed versions of Mac OS X:
- Leopard Upgrade: requires that Mac OS X Leopard already be installed.
If you have purchased an Upgrade for Mac OS X Leopard license, then subject to the terms and conditions of this License, you are granted a limited non-exclusive license to install, use and run one (1) copy of the Apple Software on a single Apple-branded computer as long as that computer has a properly licensed copy of Mac OS X Leopard already installed on it.
- A "Family Pack Upgrade for Mac OS X Leopard" license is also mentioned as a subset of the Leopard Upgrade.
- Single Use: places no restriction on which (if any) version of Mac OS X should already be installed. Used for the non-upgrade and Mac Box Set versions of Snow Leopard.
Subject to the terms and conditions of this License ... you are granted a limited non-exclusive license to install, use and run one (1) copy of the Apple Software on a single Apple-branded computer at a time.
- Family Pack: identical to the Single Use license in this respect.
It is not entirely clear which license is offered with the retail version of Snow Leopard. As noted above, Apple's website advertised this version as an "upgrade from Mac OS X Leopard for $29" and suggest that others upgrade using the Mac Box Set, implying the stand-alone retail version to be a "Leopard Upgrade" license. On the other hand, some Apple press materials appear to indicate that this version is, in fact, the "Single Use" license:
The Snow Leopard single user license will be available for a suggested retail price of $29 (US) (emphasis added)
However, even if the retail edition of Snow Leopard is in fact a "Leopard Upgrade", the company has acknowledged that there is no technical barrier in that edition preventing a direct upgrade from Mac OS X "Tiger".
The Leopard Upgrade license explicitly applies to the Up-To-Date Program (US$9.95) for Macs bought between June 8 and December 26, 2009 and the installation discs provided through this program are clearly marked as upgrades unlike either of the retail editions.

Famous quotes containing the word license:
“It would much conduce to the public benefit, if, instead of discouraging free-thinking, there was erected in the midst of this free country a dianoetic academy, or seminary for free-thinkers, provided with retired chambers, and galleries, and shady walks and groves, where, after seven years spent in silence and meditation, a man might commence a genuine free-thinker, and from that time forward, have license to think what he pleased, and a badge to distinguish him from counterfeits.”
—George Berkeley (1685–1753)
“Purchasing power is a license to purchase power.”
—Raoul Vaneigem (b. 1934)
“Surely the fates are forever kind, though Nature’s laws are more immutable than any despot’s, yet to man’s daily life they rarely seem rigid, but permit him to relax with license in summer weather. He is not harshly reminded of the things he may not do.”
—Henry David Thoreau (1817–1862)
