Upgraded my MacBook Air to both Windows 8.1 and OSX Mavericks.
First updgraded my Bootcamp partition for Windows to 8.1.
Then I used Winclone to resize the hard drive to give myself more space for Windows -- 95% of my time is spent on the Windows side, rather than the Mac side.
Next I upgraded to OSX Mavericks.
Everything is running perfectly except ... on Windows, my Quickbooks shows an error and needs re-registration. But that's simply the result of the hard drive resizing, not 8.1 or Mavericks. Not a coincidence, I suspect, that of all the software I use, Intuit is probably the one that's most monopolistic.
