How to: Virtualize Mac OS X Lion

A virtual machine (VM) is a software implementation of a machine that executes programs like a physical machine. VMs are separated into two major categories; these categories are based on their use and degree of correspondence to any real machine. A system virtual machine provides a complete system platform which supports the execution of a complete operating system. A process virtual machine is designed to run a single program, which means that it supports a single process. Any software running in a virtual machine is restricted and it cannot break out of its virtual world.

 

The virtualization story for Mac OS X is about to change, a lot. This is a positive change as Lion’s licensing changes the rules for virtual machines. In some circumstances for certain enterprise deployments, virtual Mac OS X environments are held in a very high light. By giving access to Mac only applications, the demand increases without having to supply Mac hardware on a one-to-one basis.

 

Leopard started the virtualization for Apple. Apple began to permit limited virtualization of Mac OS X, with two major caveats: you could only run VMs on Mac hardware (no blade server racks full of HP gear serving out Mac desktops). By doing this, it cost a steep price because you needed a Mac OS X Server license. Since it was so expensive, few people took advantage of it.

 

Lion’s new EULA is prepared to change all the rules. 10.7 users will be allowed to run one or two virtual Mac instances on each physical Mac. The tools will be helped by VMware Fusion, Parallels, VirtualBox or others. The people that will benefit from this are developers, IT managers and others who need to keep a known-good test environment or try out new apps in a controlled fashion. Like this article?

Sent it through AirDrop

Today, Apple has released seeds of it’s latest operating system, Mac OS X 10.7 Lion. One of the features of Lion that was not covered in his keynote at WWDC last year was the feature called AirDrop. With AirDrop, you can simply drop files to another user who is using AirDrop – pretty clever.

Send it by air.

With AirDrop in Mac OS X Lion, you can send files to anyone around you –  wirelessly. AirDrop doesn’t require setup or special settings. Just click the AirDrop icon in the Finder sidebar, and your Mac automatically discovers other people nearby who are using AirDrop. You’ll even see contact photos for those who are already in your Address Book. To share a file, simply drag it to someone’s name. Once accepted, the file transfers directly to the person’s Downloads folder. When you’re done with AirDrop, close the Finder and your Mac is no longer visible to others.
