ok Rohnie i m going to propose this :
the download of Mavericks has been completed ok ?
but the application will not open… that is because you are running a newer OS.
now… what you downloaded is an application. it must be in the Applications folder named Install OS X Mavericks.
maybe it will be grayed out with a circle and a diagonal line.
forget disk utility .
run Diskmaker X. (previously named liondiskmaker)
download from DiskMaker X
an 8gb usb drive will be needed. (i would use a fast one)
(or if you are not scared with terminal command line - don't panic- just ONE command
open terminal and copy and paste this command (make sure the usb drive is in).
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
It will do the exact same thing as Diskmaker X. (previously named liondiskmaker). of course as with disk maker X the Install OS X Mavericks app will have to be in the applications folder.
this is a sudo command. copy and paste it and just hit enter. you will need to have a password. blank password won't let the command run.
now when you type your password nothing will appear. not even dots or stars. hit enter
if you entered the command and your password correctly you will receive some lines in the terminal window that will say how the process is going .
you will be notified when it's done. no message will pop just a line in the terminal window. do not close the terminal before that.
now you should have a bootable mavericks drive.
to verify that go to system preferences and go to startup disk (4th row) . next to your macintosh HD there must appear the usb drive when pluggeg in.
ok … now the second part. had you ever had windows on a mac? if yes you would remember pressing an holding the alt / option key after the mac bongs and before the apple logo appears.
reboot with the usb plugged in. immediately after the bong sound press and HOLD the alt/option key.
you will be greeted with a screen with 3 disks. macintosh hd (thats yosemite) , recovery hd and you usb drive. with the mouse or arrow keys select the usb .
when it boots you will have a screen with a menubar the installer screen
do not click install yet.
from the menubar click utilities > disk utility . select your hard drive and click erase. (that will format the disk) when done quit disk utility
click install. the installer should proceed .
please tell me if it worked.
