Hello everyone, I know this has been covered before, but here’s how to do a clean install of El Capitán.
Cheers, Anne Download El Capitán from the Appstore. When it opens the installer, quit it. Make sure you have a spare 8 gb USB drive and give it the name Untitled. Prepare your USB Flash Drive. To format the USB drive open Disk Utility. Plug the drive into your Mac. Select the USB Flash drive from the table in Disk Utility. Select the “Erase” tab. Make sure the Format is set to Mac OS Extended (Journaled). As for the name, leave it as “Untitled”. Finally click the Erase tab. Terminal Command Simply copy and paste this into Terminal and press the Return key: sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction Since the above command uses the sudo attribute you will be required to enter your password to start the process. Once the process starts you will see this in Terminal: Erasing Disk: 0%… 10%… 20%…100%… Copying installer files to disk… Copy complete. Making disk bootable… Copying boot files… Copy complete. Done. This process can take a while since it’s copying gigabytes of data over. Leave it alone and let it do its thing. Installation. First of all, make sure you have a Time Machine backup of your system, then shut down your computer. With the installer USB drive plugged in, hold down the Option key and press the Power key. Give it about 30 seconds, then press Right arrow once if you have no recovery partition, or twice if you have. Press Return and wait. After a few minutes, press Cmd-F5 to start VoiceOver. The first screen is the Language Chooser, so press Continue. You should now have a table of Utilities. Select Disk Utility and erase your internal hard drive. (Sometimes, VoiceOver gets stuck at this point and you may need sighted help to get out of trouble). Once the HD is erased, select the installer and let it do its thing. Eventually, you will be asked if you have another computer or a Time Machine backup. This is the point at which you connect your Time Machine drive, and just follow the instructions. All your applications and data will be restored, except for any apps that are not compatible with El Capitán. -- The following information is important for all members of the Mac Visionaries list.
