caiquecastro Posted August 25, 2015 Share Posted August 25, 2015 Hello, I've found the solution to the error "OS X YOSEMITE IS ALREADY INSTALLED ON THIS MAC" where on the OS X Installer all you can do its press restart button. To fix it and continue with installation u have to copy the file smbios.plist from /Extra folder. If u have already a OS X installed in your HD with Chameleon, just copy that smsbios.plist to /Extra folder OF THE PENDRIVE or THE DVD from where you are trying to install a Mac. I was trying to install El Capitan from USB, everything went OK,but i had the OS X YOSEMITE IS ALREADY… error when trying to install, so I've copied the smsbios.plist from my Lion installation /Extra folder to the /Extra folder of the USB with Capitan and voila! Any questions ask,i hope it help. 1 Link to comment Share on other sites More sharing options...
