O SLA Snow Leopard declara textualmente:
- Permitted License Uses and Restrictions. A. Mac OS X Server Software. Subject to the terms and conditions of this License, you are granted a limited non-exclusive license to install and use one copy of the Mac OS X Server software (the “Mac OS X Server Software”) on a single Apple-branded computer. You may also install and use other copies of Mac OS X Server Software on the same Apple-branded computer, provided that you acquire an individual and valid license from Apple for each of these other copies of Mac OS X Server Software. You agree not to install, use or run the Apple Software on any non-Apple- branded computer, or to enable others to do so. This License does not allow the Mac OS X Server Software to run on more than one computer at a time, and, except as expressly set forth in Section 2C, you may not make the Apple Software available over a network where it could be run by multiple computers at the same time. Please note that the Apple Software is supported only on Apple-branded systems that meet the specified system requirements as indicated on the outside of the Mac OS X Server packaging. If you transfer software from one Apple-branded computer to another Apple-branded computer, please remember that continued use of the original copy of the software may be prohibited once a copy has been transferred to another computer, unless you already have a licensed copy of such software on both computers. You should check the relevant software license agreements for applicable terms and conditions.
