MacBook going into blank screen after Apple Logo
It's possible that something in the OS got corrupted. Boot into recovery mode (hold ⌘-R on boot for those who don't know) and select the option to Reinstall OSX. It won't touch your user files or applications; it just lays down a new copy of the OS, which will likely fix your issue. You may need to explicitly connect it to your wifi/ethernet to do this. Good luck!
