I have MacBook Air and I have installed Yosemite on it. Whenever I boot my Book, I get a 'Update Required' message and I end up updating my OS.

I recently updated my OSX Mavericks OS and now something strange is happening on my Mac Mini. When it powers up, it only displays the Apple logo and then the progress bar, which is normal. After the progress bar is full, the computer shuts down and when I power it up again, the same process repeats itself. I have tried opening it in safe mode but it does not work. A hardware test detects no problems and recovery mode does not solve anything. Please help.
