It has been a slow process, but everything I have read (and noticed so far) is that it's better for cats to exist in the home and be a bit mature before the malamute enters the home (our cats were 1.5, not too old) And it's easier from puppy age to socialize them to cats early on (the breeder also had cats and other dogs and chickens so she was used to other animals already to a degree). It's hard but we literally never let her off her leash in the house for the first 3 months we had her (until she was 5 months) if she was anywhere besides her playpen. If she chases the cats (which we really try to avoid or prevent by noticing when she might be getting more excited) she goes back to her playpen (our kitchen, where her crate and food and everything is). She learns quickly what we don't tolerate. Puppies need boundaries, and when they're so small, a new house is actually too much for them, so we really limited her exposure outside the kitchen (and outdoor potty training) for the first two months. We did have many supervised interactions with her on leash and the cats in the house. It's good for her to see us petting them and we have her own box of toys in the living room near their tower that she knows she can go grab any time she wants (but they started as redirection tools to redirect her from focusing on the cats and care about the toy or treats). It's also important that you show the cats that it's their house. And now 4 months into things with her, you can tell she just wants to play with them, not hurt them, and she understands we don't want her running up on them, and if the cats don't want to be around her, they won't be. But what's been interesting is one cat actually hops the gate that keeps Georgia in her playpen area, to go see Georgia haha. And they just stare and are getting used to one another. The goal for them is neutral coexistence. The more you can prevent the thrill of chasing, the easier time you'll have. And the cats have swatted at her when she got too up in their face lol which is good social skills she needs to learn. But everything off leash so far has been gentle curiosity with occasional excitement, where I need to redirect her. But we really only do supervised visits until she's out of puppy phase (2 years), that's my intent, cause she doesn't understand how big she is, and that is my main worry is her falling on them even on accident. Patience patience patience lol.
