Os X Yosemite Requirements
To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
Apple previewed OS X 10.10 Yosemite on June 2, 2014, at the Worldwide Developer Conference (WWDC). In addition to a lot of new features and a whole new level of integration with iOS devices, Yosemite looks like the most beautiful version of the Mac OS to date. Append the OS X Yosemite bootable installer drive to the Mac, at that point reboot as typical. During boot down the OPTION key until a boot determination menu shows up, pick 'Introduce OS X Yosemite' as the drive for sure (this is the USB installer). When the 'Operating system X Utilities' screen shows up, pick 'Disc Utility'.

Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
Lion System Requirements
1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
or Xeon processor
2. 2GB of memory
3. OS X v10.6.6 or later (v10.6.8 recommended)
