I purchased Lightroom 1.3 for Windows in 2008 and I need to know how I can migrate Lightroom over to my mac.
Download Lightroom 1.4.1 from https://www.adobe.com/support/downloads/detail.jsp?ftpID=3891
Follow these directions to move your Lightroom from one computer to another
Just a word of caution: I am pretty sure Lightroom 1.3 or 1.4.1 will not work correctly on any current version of Mac OS X (or windows for that matter). So you might need to upgrade to a newer version in the process.
