There are times when you’re computer starts to act a little strange. This could mean that something is wrong with your system’s software. You might even have to reinstall your software in order to fix the problem. This is OK, there’s nothing to worry since this is an easy problem to solve.
When you purchased your Mac computer it came with the original software disks for Mac OS X and simple instructions you can follow to reinstall your Mac OS X software.
If you feel like you should, be sure to backup all our data on an external hard drive or CD. When you reinstall the software you could lose everything on your computer.
Once everything is backed up, insert you OS X install CD and double click on “install Mac OS X” when the option pops up. Click on “restart” when the next windows opens, which should say “install Mac OS X.” This is going to install the software onto your computer.
You’re going to need to type in your username and password when the box pops up requesting you to do so.
Choose your language preference when your computer restarts. Then hit the blue arrow to continue. You’ll then be asked to agree to the TOS on your computer’s license agreement. Click continue.
Next click the hard drive as the destination for the installation.
You need to choose what type of installation you want. “Archive and Install” will install the newest version of OS X onto your computer. It will leave your old files and move them over to the folder called “previous system.”
If you want to save all your files and accounts choose, “preserve user and network settings.”
If you choose “erase and install” if you want to completely wipe out your computer, removing all your files, folders and data.
Now let your computer install the software. This can take several minutes to several hours.
