Early 2011 MacBook Pro 13" - 16 gb ram - replaced HDD with SSD Samsung pro 840 - running Mavericks My problem currently is that my MacBook is stuck at the white loading screen with the animated loading icon. Before this happened, I was reading an article using text -to-speech and I noticed that the words were being skipped. I figured that my internet connection may be the problem, I ended up trying to restart my computer instead and noticed that it wouldn't do it even if I clicked on restart or shut down. I tried to shut the screen to see if it takes me back to the login menu but when I opened the Mac it was still on my desktop. Anyways, I tried to shut down the Mac holding the power button and when I started it up, the Mac is now stuck at the loading screen. I was not doing any sort of OS installation or update, was just browsing websites with barely any programs running in the background. I would like to be able to find a solution without having to do a clean install or losing my data. I don't have a time machine back up. I read that you can boot up to the OS X utilities via holding recovery buttons, could I do this and chose repair disk without losing any data? Would love any advice you guys can give, thanks.
