error messages? what version of lightroom?
4.0! and is telling me to update it, but when I trying to do it automatic got frozen, after that stop working at all.
there is not showing any errol messages.
Lightroom isn't an Apple App, the problem most likely is with Lightroom itself, please navigate to a Lightroom forum or contact Adobe's support to troubleshoot.
Your welcome and good luck, I'm sure once you get it sorted out Lightroom will perform OK.
