Recently, the Mac App Store ceased to provide a means to purchase full copies of most of its Free Store applications. The recent release of Lion did not support Lion's USB installer discs for Macs that could have been used to avoid using a disc drive when installing Lion - but instead one would have to use an external drive.
The installer for Lion is a single file at approximately 4.4 GB in size, so a storage device similar to a USB thumb drive or bigger could be used to store that file. Unfortunately, Mac OS X on your desktop might be in use and you will have to restart your computer in order to perform this installation run, even if you are installing Lion on another Mac computer on your network.
After downloading the installer for Mac OS X Lion, make sure to save it to your desktop. You will then need to install the installer onto your Mac by following the easy steps outlined below and purchasing an external hard drive for Macs to use as well.
If you run the installer, but the computer freezes right after you click "Install Now," you may be one of the people that experience the installation freeze problem on Mac OS X 10.6, 10.7, 10.8, 10.9 and 10.10. Solution: Check your internet connection and/or internet disconnect issue. d2c66b5586
