In other words, in our view, you should be well within your rights to install Mavericks on any of your computers for which you have a valid, current Snow Leopard, Lion, or Mountain license-even if you don’t actually install Snow Leopard first. While the letter of the law says that you need to install at least Snow Leopard before installing Mavericks, the spirit of the law seems to be that a particular Leopard-equipped Mac just needs a license for Snow Leopard, Lion, or Mountain Lion before you can upgrade it. Having performed this two-step upgrade many times while researching our various Mavericks-installation articles (and the past two years while writing our upgrade guides for Lion and Mountain Lion), I can tell you that it’s a real hassle.īut lets take a step back.
This is just one scenario-I can think of a number of situations in which you might have Leopard on a Mac or an external drive, along with a valid license for Snow Leopard, and you’d rather not take the interim step of installing Snow Leopard just to upgrade to Mavericks. But what if, for example, you’ve got a family-pack license for Snow Leopard, and you’ve got a Mac that shipped with Leopard but that’s never been upgraded to Snow Leopard, Lion, or Mountain Lion? The Mavericks license agreements say that even if that Mac is compatible, you can’t upgrade to 10.9 until you first install at least Snow Leopard. As far as developers are concerned, the integration of Grand Central, OpenCL and a 64 bit kernel will allow you to take full advantage of the dual processing power of Intel Macs.That seems pretty clear. If your Mac is operating at a slow pace, then for that reason alone it is worth the upgrade to OS X 10.6 Snow Leopard. Faster Installation Time: Installing Snow Leopard on multiple machines takes approx 15 minutes in comparison to around an hour for Leopard.Microsoft Exchange Server Support: Mac users can now connect to Microsoft Exchange 2007 servers via Mail, Address Book, and iCal.
