Forced to re-install Mountain Lion
I've been using Mountain Lion for about 3 months with no serious problems
except for repeating stupid message about local hostname changing.
I just did an ordinary restart and instead of usual home window, I was presented
with several options in order to proceed. The only one that worked was re-installing
Mountain Lion after being forced to change Apple ID and Password.
Anyone know why this happened and how to prevent in future?
Thank you.
