Can Mac Software put installed on more than one computer?

Answer 1

If your question is "Can Mac OS X operating system be installed on more than one computer", the answer is technically yes, but you are legally limited by the license agreement. If you contact Apple Computer for free technical support of the OS X installation, they may ask for the serial number of the computer. Then you are tagged in their database as installing OS X on that computer. What happens if you call them for free support after installing on another computer? Hmm..... But you can also buy the OS X disk with a family license for 5 computers and pay a higher price.

If your question is "Can third-party Mac software, such as Photoshop or Quark XPress be installed on more than one computer", the answer is yes, no and maybe. I won't go into details here but some software will automatically send info to the web site of the company when you are connected to the Internet. Then your computer is automatically registered as the one with the first installation. Some hackers know how to avoid this auto-registration.
