Here’s some of the info you can find in iCreate issue 123, along with some reference tables with what you can expect:
iMac
Providing your iMac is a mid-2007 model or later (all the way up to the present day, super-slim models) you should be fine to install and use Mavericks on your desktop machine.
MacBook Pro
13-inch MacBook Pros from mid-2009 or later are currently supported by Mavericks, as are 15-inch models from mid/late-2007 or later and the 17-inch model from late-2007 or later.
MacBook Air
The late-2008 model MacBook Air, and anything more recent than that will happily run OS X Mavericks, according to the developer preview so far, so long as there’s enough disk space for the install.
Mac mini
Mac mini models launched in early-2009 or later will run OS X Mavericks once the upgrade hits the Mac App Store later in the autumn.
Also
If you’re lucky enough to own an original MacBook, you’ll be pleased to know that the late-2008 aluminium model, as well as those from early-2009 or later, will run Mavericks. Similarly, Xserves from early-2009 or later will also run OS X 10.9.
And finally…
The minimum requirements for Mavericks at present are 2GB memory, 8GB of available hard drive space and at least OS X Snow Leopard running to install Mavericks.
