How To Install OSX Lion

For users who are currently using the Snow Leopard operational system it could be worth looking into upgrading to the OSX Lion. Before doing this there are a number of factors of note that should be taken into consideration regarding IT installation.  Computers that are a few years old may not be compatible with newer operating systems due to the requirements demanded of modern packages such as the Lion. The next point of note is that it would be worth backing up all data before installation and reformatting a computer.

Checking requirements

The OSX Lion operating system will need a specific processor to install properly; any from the Intel Core 2 Duo, Core i3, Core i5, Core i7 and Xeon are all good.  Another requirement is that a minimum of 2GB Ram must be left free with an additional 4GB of spare hard disk space available also.

Back Up Your Data

 Before commencing with IT installation it is imperative to make sure all data on your hard drive is backed up. One option for doing this is using a back-up system called Time Machine; by running this it gives the user the peace of mind to not have to worry about installing a manual backup.  Failing this an alternative option is to invest in an external hard drive to store all data. It is essential to make certain that all data in every folder is backed up; this includes folders you may not necessarily think to copy including “Download” and personal “User” ones.

Downloading the OSX Lion Software

In iTunes software open the “App store” and browse for updates. Once the OSC Lion update has been found it is possible to click on this which will bring about a prompt for you to enter your details. From here it is as simple as downloading the software and then launching the upgrade once this is completed.

How To Reformat

From here the user should click on the icon marked “Desk Utility”; this will in turn open a new menu where the user can click on the hard drive. All information from the hard drive should be safely stored elsewhere as the next option the user should select is the “Erase” button. This, as could be guessed, erases all the information contained on the computer which will allow a fresh installation of a new operating system – in this case the OSX Lion.


A number of prompts should appear on screen which the user can then click through. The hard drive should be selected as the installation point for the OSX Lion and, once this is done, the next step is to press the “Next” button and simply wait for the setup to begin. Dependent on computer speed the process could take anywhere up to three quarters of an hour. Once this is complete the user will be invited to enter their username and password and then chose a wireless internet network from a pop up menu. Once this has done the computer needs to be restarted so as to run with the new system installed.  The final step, at this point is to re-upload all your previous data from either the Time Machine backup or from files stored on the external hard drive. Once these steps have been completed, no information has been lost and the computer will have a new OSX Lion operational system in place.
