I need assistance and guidance in installing my already purchased Lightroom Version 5 (registration 2015) onto my new macbook pro. I already have it installed on my iMac, but my iMac is older and running slower now and I want to move Lightroom to my newer laptop. I have called Lightroom support and they directed me to post in here for assistance.
Note that you will not be able to install 6.14 on a Mac which is running one of the Catalina, Big Sur or Monterey versions of MacOS, which I assume the new MBP will be using (the 6.14 install process has some 32-bit elements, which cannot be run on those operating system versions). However, if you use the Migration Assistant to port the already-installed version of 6.14 from your iMac to your new MBP, that should allow you to use it on your new system. If you ever need to do a re-install though, you'll not be able to do that on the MBP.
