El Capitan

Tips for successfully installing El Capitan

- When Updating from older OS, Manually set the date to January 1st 2016 or the installer will fail

- When installing from a pendrive/boot disk enter terminal and enter 'date 0101012016' this will set the date manually to January 1st 2016, and the installer should work.

Make sure your disk is not formatted in AFPS, as it will not be detectable by the boot loader.
