If you have a computer, it’s a good idea to run the latest version of the operating system that it can support. For Mac computers, the program is called OS X. The newest version El Capitan will be released on Wednesday, September 30th.
If you don’t have a program such as Super Duper or Carbon Copy Cloner (which is what I use) to clone my hard drive give Backup Pro a try. It is free until September 30th.
Don’t lose your crucial data (photos, emails, documents). Back up and clone your disk with Get Backup Pro, and be able to boot up your Mac and access your files always! FREE until September 30, 2015.
