I have Lightroom 4.4 running on Win PC. I recently purchased a Mac and want to upgrade to Lr 5 AND transfer everything to my new Mac. Would this process be achievable fairly easily?
It is a fairly simple process to upgrade and move to a new computer as long as you keep all of your ducks in a row. To install an upgrade version of Lightroom 5 on the Mac you will have to have the serial number from your Lightroom 4 available. Lightroom 5 will have a new serial number, but as an upgrade it will require a you have the Lightroom 4 serial number as well. The process of moving Lightroom to a new computer is well explained here:
