Just out of curiosity, what version did you have before? > I have not been able to > determine my version of command line tools. Where on my mac do I check the > version of command line tools? I don't actually know. But you should use the version of the CLT that matches the version of Xcode. So if you're upgrading to Xcode 4.6.3 now, you should upgrade to the corresponding CLT (April 2013) at the same time. > Are there things I should backup before > starting these upgrades? Probably no need. In the unlikely event that you have problems with the new Xcode and CLT and want to go back to the old versions, you can follow Apple's instructions in the read me file for uninstalling them and then install the old versions again.
