I am selling my old rMBP (2012), I wiped the drive and it rebooted to the recovery partition. So far so good. After setting up the partition using disk utility and going to reinstall the OS it fails to download Yosemite from the mac app store. It says something along the lines of "operation couldn't be completed, try again later." This is over the past two days. I also am trying to download Yosemite on my new retina MBP (2015.) It tells me "OS X Yosemite is already installed." If I try to download it on my work iMac I get a different error and can't download it (Same iTunes account.) Has anyone ran into this issue? Is there any way to get the machine to install an OS properly without getting a USB installer? Is my iTunes account bugged?
