Because I am obsessive with all my software after over 30 years of dealing with it.... my update went smooth as silk on my MacBook Pro. Tools and performance and coloured tracks alone were worth the upgrade imho. When I was young I was one of those that tried pirated software then bought it if I liked it, when shareware was also a real thing :). These days cost of development has gone up, demand to make that next leap, or keep up with the Jones and changes in OSes is even more intense. I can afford to help keep my current favourites in work, and I do :).
