At no point was Microsoft spending more on Office for Mac than they were making on selling the Mac version.

It cost some. But famously Microsoft used byte code for Office that was portable and was dog slow around Office 5.

And it’s not my “believing”, it’s math. Apple lost far more than the net $150 million before it became popular.

This isn’t my reading the history books. My first computer was an Apple //e in 1986 and by 1993, I was following what was going on with Apple real time via Usenet and TidBits (been around since 1990) and I lied to get a free subscription to MacWeek.

The fact is Microsoft did spent R&D money to support Apple customers, with a product without which, Apple would even be less relevant in the late 90's.
