Since you're having problems with Recovery Mode I suggest you reset your Non-Volatile Random-Access Memory (NVRAM). Please note that if you haven't downloaded them directly from Apple then there is no way for anyone here to confirm the suitability/safety of what you've downloaded. IMPORTANT - Your question doesn't specify where you've downloaded the installers from.

My guess is that the copy of Yosemite you've downloaded is either 10.10.0, 10.10.1 or a build version of 10.10.2 earlier than 14C2043.

To start with your MacBook Air will not run Mavericks, so you can put that one aside as incompatible.Īs for Yosemite, the earliest possible version that will run on your model MacBook Air is actually Mac OS X 10.10.2 (build 14C2043).
