I bought a new Mac just for photo editing, but Lightroom still feels unreasonably slow on it. I have tried both Lightroom and Lightroom Classic, but both are not nearly as responsive as I would expect. Especially when doing things like using the Heal tools. Are there any settings I can adjust to make it operate faster?
You definitely don’t have enough RAM, I recommend closing everything you can that would be running in the background, and then also try building a new Lightroom catalogue with only a few photos in it, see if that works better
