Hello, I own a license Lightroom 6 for Windows, I can use it on a Mac or do I have to buy a new license. Thank you
There is no need to buy another license.You can use one License of Lightroom 6 on two computers at a time.
As per your Records you have a Multiple platform license.So you could install it on Mac as well.
In case you need download link for Lightroom 6 .Use Download Photoshop Lightroom
Many thanks greetings.
