Question: can yosemite be upgraded to el capitan?
Answer: El Capitan is Apple's marketing name for OS X version 10.11, the latest update to your Mac's system software. If your Mac is running Yosemite (10.10), Mavericks (10.9), or Mountain Lion (10.8), it can run El Capitan. Beginning September 30, you can download El Capitan straight from the Mac App Store.
