“At the time of writing, Apple has not announced any pricing information. [for OS X 10.9 Mavericks],” Johnny Winter writes for Mactuts+. “Over the years, subsequent versions of OS X have been offered at ever increasingly value-for-money prices… OS X 10.8 was only available as an upgrade through the Mac App Store and cost £13.99 in the UK. Compare this to £99.99 for Microsoft’s Windows 8 operating system, and any upgrade to OS X is an absolute steal!”

“In order to run OS X 10.9 Mavericks, your Mac must have at least 2 GB of memory,” Winter writes. “From my own experience of running OS X 10.8 Mountain Lion, on a Mac mini, my recommendation would be to look at 4GB being an absolute minimum for Mavericks, otherwise it you run very slowly indeed.”

Winter writes, “Better still, I’d recommend at least 8GB or more if you can afford it.”
