Excuse my ignorance, but how can I tell what verion of CarbonLib I have installed on my computer? Apple has just recently released a stand alone version of it's CarbonLib 1.6 http://docs.info.apple.com/article.html?artnum=120047 Apparently it was available through Sofware Update too. I've updated regularly, and don't recall having downloaded CarbonLib 1.6 from the Software Update. Nor does it appear in my Software Update Log... So, how do I tell what version I've got installed, and do I need to install it if I've got an older version? In updating, what risks do I run, and what backups should I make, if any? Thanks.
