upgrade mac operating system to snow leopard

One thing is relatively certain, however: Using the $29 Snow Leopard upgrade on a Mac running Mac OS X 10.4 is a violation of Apple's End User License Agreement, or EULA. 'My assumption is that it should work simply because the DVD has to be able to boot and install onto a system that has a damaged OS, or that you want to do a clean-install on,' Faas said in an e-mail.Īpple's public relations team did not reply to questions today. However, Ryan Faas, who wrote 'Upgrading to Apple's Snow Leopard OS: What you need to know,' noted that the possibility made perfect sense. 'Apparently it installs even if you have Tiger.'īecause of a lack of Tiger-equipped Macs, Computerworld was unable to immediately confirm Mossberg's and Chen's contentions. 'Our tests confirm 10.6 DVD works for Tiger Macs too,' wrote Brian Chen, a reporter for on Twitter. Others confirmed Mossberg's note that Tiger users can go the cheaper route. Only users running Vista can upgrade in-place. The only way to upgrade from Windows XP to Windows 7 is to do a clean install.

If Tiger users must conduct a clean install with the $29 upgrade, they would be in the same boat that Windows XP users will be come Oct. (Snow Leopard's default for Leopard users is an 'in-place' upgrade that retains all data, settings and applications.) Answers to important questions are scarce, however, including whether Tiger users would be required to do a so-called 'clean' upgrade that involves backing up their data, erasing the hard drive, installing Snow Leopard, then restoring their data and reinstalling all applications.
