Help!! Is this normal for installation of Mac OS
Hi guys,
i'm really confused now as to what is happening. Not really a mac user and i got an imac 2011 that i need to reinstall OS on as it was previously unable to install and there wasnt any time capsule backup
after creating the USB drive for installation, i proceeded to select it after pressing option on start up and after that this showed. is this normal? how long should i wait for it
iMac 21.5", OS X 10.11
