So this issue of MacBooks booting to a black screen with a cursor seems to be relatively common. I've researched and tried different solutions over the last couple of day and to no effect. My 2008 MacBook Pro seems to get to 25% (sometimes 50%) on the loading screen before booting to a black screen with the white cursor... I'm thinking it has something to do with Yosemite?? Here's what I have tried so far: 1. Connecting to an external screen to check the display. (The logo still lights up on the front anyway) ## 2. SMC reset ## 3. Booting in safe mode to login in the dark ## 4. Booting in recovery didn't work ## 5. Zapping PRAM (NVRAM) ## 6. Target disc mode works on my desktop Mac do I know the hard drive is ok. 7. Terminal boot finishes on #Bash 3.2, I tried researching that but it's a little over my head! Any ideas fellow users?
