Mac won’t boot after login
my MacBook won't complete the login sequence, it allows me to enter my passcode and starts to load but then the indicator bar gets about half through the process then freezes. I tried the Disc resets and tried to reinstall but I don’t have enough space to re-download it and can’t login in to make space. How do I either make space without logging in or get in without redownloading it. Or am I just screwed?
MacBook Pro 13", OS X 10.10
