I changed my mac from 64bit to 32bit for work purposes.
Now need to change back to 64bit
How do I do this?
Mac Pro, Mac OS X (10.7.5)
Pick your option to reboot from those here - http://support.apple.com/kb/HT3773
(i.e. choice of setting it back to 64bit kernel permanently or only until the next restart).
