Single Lightroom catalog that can be accessible by Lightroom (Windows) and Lightroom (Mac)
Currently, I have Lightroom running on a iMac and a smaller MacBook Air. The catalog is on a portable drive that I can take around with me while traveling with the MacBook Air. However, the MacBook Air is nearing it's end of life and I want to start using my PC laptop for traveling. I know I can install Lightroom/Photoshop CC on my PC laptop, but I need to know what to do so that the PC laptop and the iMac recognize the portable drive where the catalog resides. Any guidance would be appreciated.
