I have just read a few threads on the subject and think that I have a general grasp on the idea, but I want anyone elses opinion. Myself and four other friends of mine own Mac's (I got them all to switch!) and two of them are very excited for Leopard while the other two want it because they want to be up to date. In short, everyone of my friends, including myself, wants it. So I figured that we would all pitch in and get the family pack and share it amongst each other. Because first of all, we're all students with limited income and bills to pay as it is, so splitting the money is like sharing an apartment, it just makes things simpler. After reading around on the forums, people seem to be saying that I am not allowed to buy a family pack copy and install it on multiple Mac's that do not reside in my home. Now I assume this is where ethics can come into play because if we purchased the software, don't we have the right to legally place it all on our machines? Since we are not re-selling or re-distributing? Is Apple trying to secretly say, "we're watching your every move" and that if I so dare as to put Leopard on another person's Mac who doesn't live with me that they are going to find out and that I will loose Leopard all together via some software update or something? I'm a bit confused at this, because when I see the term "family pack" I normally just use the term "multi-pack" because to me it's just multiple copies of the same thing. Now I FULLY understand the whole argument about, "well you do understand that you are only getting one single install disk" and that if theoretically something were to go wrong with someone else's machine and they needed to reinstall the disk the person who has the disc would have to get it to them. Theoretically if I purchase the family pack, am I allowed to install it up to 5 computers, period? And what would technically happen if I attempted to install it on a sixth or seventh? (I assume this would be grounds for being illegal, it is a hypothetical question as I only have 4 other Mac user friends). I appreciate any replies, and thanks.
