Hi there Brendan Choi,

It sounds like you downloaded the Mac OS X 10.10 upgrade from the Mac App Store but it failed during the installation process. I would start by deleting the update file in your Applications folder, then boot into Safe Mode:

Try safe mode if your Mac doesn't finish starting up

Once you log into Safe Mode, restart the computer and try updating again.

Thank you for using Apple Support Communities.
Take care,
Sterling

Does your Mac meet these requirements for Yosemite?

These are the requirements for Mt Lion.
