Not gonna happen. It gets brought up mainly because Apple has a HUGE war chest and no one know what Apple is going to use it for. But as others have said, Disney would not make any sense for Apple as an acquisition. Yes, it would give them some content, but the rest of it is not anything Apple would have any care to get into. So, not concerned..... because it will never happen.
There are other companies that COULD buy Disney which would be a bigger concern to me. Years ago, I would have been concerned about Comcast, but they took a different tact and have been sitting back and enjoying trouncing Disney's parks at every turn, purchased Dreamworks, NBC/Universal, etc, so I doubt they could anymore with the anti-trust lawsuits.
Verizon could be a possibility if someone was looking to pick up Disney at a discount with all of it's problems. They would have to be insane, but if they wanted to get into an all out street fight with Comcast and AT&T, a purchase of Disney would catapult them into a comparable position with their 2 major competitors (on one side they have NBC/Universal, and on the other they have HBO/MAX and Time Warner and Verizon has nothing to combat either). Im also not sure they could afford it, and it would be a huge leap for them.
