I currently have both Lightroom and Photoshop installed on my MacBook Pro. I need to get a new laptop and I was wondering how to transfer these programs onto my new device? Do I have to buy a new one or will my old programs still work? I only installed it on one device, total.
I can't speak for Photoshop.
For Lightroom, you can download and install it on your new computer, you would not have to purchase another copy, as long as you can find your current serial number.
