Does anyone know if there is a USB stick or CD version of the download available ? (I'm in the UK) What is the filesize for the OS download? I'm currently using Lion on my 2011 MAc mini. Not sure how I can get hold of the upgrade (I couldn't get the Mavericks one) as the file size is probably too big. I have 3GB monthly usage cap on my broadband so can't download more than that in a month. Also last time I downloaded the ligthroom upgrade which was about 1GB it took about 24 hours to download so if more than 3GB it could take a whole weekend just to download.... So ideally I would want to instal vua USB stick or CD, otherwise I'll stick with Lion. Thanks.
