Since I have iLife '05, I am planning to sell my disks of iLife '04. How legal is it, if I registered my software? Somewhere I read that Apple gives you the license to give your software to another person if you are not using it anymore. Now, if it's true, then, I have another question. I bought some disks from a guy time ago, he did not need his software and told me that I could register it. I installed in my mac, and I tried to register the software. Once I did, after I tried upgrading the software. It locked and the key number that came with the CD's was no good to unlock the upgraded software. So I had to uninstall and re-install it, and never upgraded it ever since, so it won't lock again. So how does this passing of software works? I hope I am explaining my dilemma properly. Thanks.
