Yes, I use Bambu Studio on my Mac as well as the open source "Orca" slicer, which is essentially the same program except Orca gets some more experimental things added to it that Bambu may/may not add in future releases of Studio, as both move along with updates.
Both programs work pretty well for me on the Mac. I do *sometimes* get a fatal crash that causes the app to close. But to be honest? I feel like Windows users probably get the same experience? It doesn't happen often. There are just random occasions where, say, I open a large file and send it to the printer and it might send 100% of it and then suddenly close/crash. But I often keep the app on screen and running for days at a time, and can keep going back to it to load/print a number of different projects. So it's stable enough to do that.
I've also, rarely, had other odd behaviors like it refusing to re-sync the list of filaments I've got in the AMS unit on my Bambu X1C, or one time the other day? It just decided to make the entire toolbar of settings disappear, so I had the 3D model on my screen and could move it around or even right-click on it and do things to it. But the main list of options to modify were no longer accessible. Had to quit and go back into it to get everything back. Again, not real sure these aren't just software bugs that happen on any platform?
