I installed the latest Java update for Mac last Tuesday (7u45). When I
shut down the Mac, I noticed that it took ages (several minutes), then
today (didn't use it on Wednesday) it wouldn't boot. All it showed me
was a white screen. I tried all the recommended remedies, but nothing
would help. I finally restored it from a Time Machine backup that was
pre Java 7u45. Now the Mac works again.
I wonder if it was the Java update or something else. I downloaded it
from http://java.com/en/download/mac_download.jsp?locale=en.
My system is 10.8.4
If you boot your computer and hold down Command-V it will boot in
verbose mode. This let you see what's going on and possibly what's
actually causing the problem.
You can also boot in single-user mode. This will get you a minimal shell
environment allowing you to fix the problem, like remove files causing
the problems.
