I was trying to follow the Apple documentation on how to do a clean reinstall on the MBP only to find out that the App Store won't download Mavericks anymore because it was removed from the App Store. The serial number associated with the MBP tells the App Store to find Mavericks, it won't look for the latest OS which is Yosemite. What are my options other than walking into the physical Apple store and getting a reinstall done through them? We have another Macbook that still has Mavericks on it but I can't find any installer in there. If I "download" Yosemite on the App Store, will I be forced to install Yosemite on that machine? Or will it just be a dmg file that I can move over to a flash drive? Can anyone help? I'm really confused and frustrated with how the reinstall process works.
