I'm using
Draw Things, you don't have workflows and such in it like Comfy & A1111, but you can use any models, loras, embeddings, controlnets you want. You can train loras too. The devs have done some serious optimization for Mac. It even runs on machines without a lot of memory. I've used it on my phone, which actually works if you're keeping resolutions reasonable and quantize your models (which you can do in-app). It's not as fast when running on iPhone or iPad, but it works.
The only thing I don't like is there's not a lot of community documentation on it, but there's a discord and people post plenty of information on benchmarking and settings, so that's probably the best resource on getting started with it if you give it a try.
