So I usually download the updates manually
I get the Combo update so that I can use it on any of the machines, and to keep around if I do a clean install on a machine and want to update it quicker. In the past I've always been able to use Combo updates on any of the machines, even on machines only 1 release behind. Is that no longer possible in Yosemite?
Edit: The Delta (non combo) update ran fine...
I believe with Yosemite, when you try to do an erase and install (with a USB stick, with 10.10) it forces the machine to go to the most recent version of Yosemite unfortunately. If you watch the steps of installation, the first thing it does is 'download additional components' before installing anything. Tried this the other day when we had to wipe a co-workers laptop, and used our OS X 10.10 USB stick. It required an internet connection for us to install OS X. I am not sure if this is what you were referring to, but I found this very odd.
