I have an iMac Late 2013 and keep getting this error message when trying to upgrade. I was able to upgrade Apple Music separate with no problem but iOS don't want. Please help.
iMac, OS X Yosemite (10.10.3), Late 2013, 27"
I fixed the problem by downloading from Apple website rather than from an update on my iMac
