I'm trying to upgrade my Mid 2014 Macbook pro from OSX Yosemite to El Capitan GM Beta. I have downloaded update today but while upgrading, installation stops and throws the following error.
OS X could not be installed on your computer
This core storage operation is not allowed on a sparse logical volume group. Quit the installer to restart your computer and try again.
Anybody know how to fix this error?
Your help much appreciated.
