I know this has been asked before, but I don't think it has ever been answered. Most of the support topics on the Magix site refer to the Windows version of Sound Forge only. I moved my home Mac to the office and bought a new Mac for the home studio. I am trying to move Sound Forge back home where it belongs, but there doesn't seem to be a way to do so. All paths lead to a field requiring my Mac's ComputerID, and nobody has been able to explain exactly what that is. There is even an asterisk next to the word, but it doesn't refer to any footnote lower on the page. Magix has not responded to two requests for information (other than asking me to refrain from submitting more than one request). I don't wish to sound like a troll here, but I am ready to jump ship to Wavelab or another audio editor because of the lack of support from Magix. It shouldn't take weeks for them to explain to me what the Mac's "computer id" is, but this is a question that clearly seems to annoy technical support.
