I have a early 2008 Mac pro with Lion 10.7.5 installed. I have tried to update to Mavericks 10.9. from a usb drive. The installer files are on the Lion drive, but it did not update to Mavericks!! Did i miss something? Any help is much appreciated!
Mac Pro, Mac OS X (10.7.5)
Which method are you using to create the bootable flash drive?
And I would leave your current system alone unless you like risks or have suitable backup clone(s).
I used terminal, creativeinstallmedia and this command: sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
This was on a usb flash drive. It created an install on this disk. It was installed on the Lion start up drive.
Yes, I backed up to 2 different drives.
Mavericks Install Problem!
