I've got a 2011 iMac and a 2011 MacBook Pro, and updated both from Mavericks to Yosemite. In both cases, the recovery partition did NOT update. It's still a 10.9 recovery partition. I've talked to Apple support and (of course) they hadn't heard of this issue. Has anyone else noticed this apparent bug? P.S. I'm guessing if I were to wipe my drive and do a clean install of Yosemite, it would create the proper recovery partition, but that's a long drawn out process and frankly, it should do it properly when upgrading from Mavericks. So to those who suggest a clean install, that's not the point. If this is a widespread bug with the 2011 models (and possibly other late model macs) then that's what I want to find out.
