Harold Lloyd's course was definitely designed by Billy Bell. Not Mackenzie.
As for Charlie Chaplin, I have been trying to find any evidence that he even had a course of his own, but without any real success. Mac's involvement in it, if it existed, is I believe speculative at the moment. There was also a mention that Sean Tully found that he may have designed a course for Douglas Fairbanks Sr, at the "Pickfair" property he owned with wife Mary Pickford. Fairbanks was known to Mackenzie personally - there is a photo of the two together at Pasatiempo in the Graham collection and printed in Geoff Shac's Cypress book. Perhaps Fairbanks introduced Chaplin to Mac as Chaplin's house was just down the hill from Pickfair, with Lloyd's house closeby too. Fairbanks may have had a course on his property at Rancho Santa Fe, at least it was mentioned when he brought the property, but I was never able to find any evidence that a course was built there. Its all a bit unsubstantiated.
I think though that we can certainly say he did design and build a pitch and putt course somewhere in California. There is not only the reference in "Spirit of StA", but there is another somewhere else that I can't put my finger on just know, but will if I can find it.

As for the suggestion AM's bones were interred on Mare Island, I think that is a very far fetched rumour. I thought he was cremated and his ashes spread at Pasatiempo?
