I can imagine what the thought certainly occurred to many readers, when they noticed the headline of this post - "What someone may need to use two different versions of OS X on one Mac? ". Let's say you work for need to run a few older PowerPC-programs that do not have a optimization under modern operating systems. On the hand there is the old model of the iMac, which as the main system for this purpose uses Mac OS X Snow Leopard. How did it establish, for example, Mountain Lion, to get access to all the new programs? There are two possible solutions to this problem.
Firstly, you can buy a separate hard drive, format it to Mac requirements and install it on the correct version of Mac OS X. When you need to switch between systems, just start the "System Settings", select the tab "Startup Disk" in the list, select the appropriate drive.
When it comes to installing Mountain Lion, it is necessary to take into account the minimum hardware requirements. Officially, the latest version of the desktop operating system can be installed on the following computers:
- iMac (2007 model or newer)
- MacBook (model 2008 or newer)
- MacBook Pro (model 2007 or newer)
- MacBook Air (model 2008 or newer)
- Mac mini (2009 model or newer)
- Mac Pro (2008 model or newer)
- Xserve (model 2009)
Also for updates on Mountain Lion requires 2 GB of RAM, 8 GB of hard disk space and installed OS X Snow Leopard 10.6.8 (or OS X Lion).
There is another way - a virtual machine. You can buy products Parallels Desktop 8 for $ 80 or VMware Fusion 5 $ 50. Both of these solutions are installed on Lion and Mountain Lion and allows you to run other operating systems (including Windows, Linux and older versions of OS X).
