Can I still download OS X Mavericks for Free? I never upgraded to Mountain Lion or Mavericks and now that Yosemite has arrived  I thought of upgrading but I find that some of my software will not work with it. So I would like to upgrade to Mavericks for now. Is it still possible to get the free upgrade? I no longer see it listed in the Mac App Store.
Yes, it is still possible to download Mavericks: http://www.techspot.com/downloads/6268-mac-os-x-mavericks.html

That is a upgrade from Mavericks 10.9.4 to 10.9.5 (not a full version of Mavericks which is a 5.3 Gig file.)

But maybe the software not working on Yosemite may neither works on Mavericks.
