The problem above is easy to workaround until the problem is fixed
upstream (by overriding comint's `rear-nonsticky` property with your
own).  For the MacOS issue, I have no idea: maybe it'll be difficult to
workaround, or maybe it's specific to unusual setups (really, I'm at
pains to imagine how `cursor-intangible-mode` can cause the problems you
describe, so I'd tend to suspect an interaction with some wild-west
package doing dangerous things).

It has its share of brokenness, don't worry ;-)
