With Apple's notoriously exploitive RAM upgrade pricing, I don't believe for a second that they're not still making a profit with that pricing.

Edit:

512GB was $4,000 when it was available.

512... GB? GET THEM!!!!!

The most ram I’ve ever had in any computer is 16gb, but I just make documents and do minor photo editing. Would YouTubers and video editors be the kind of folk to make use of 512gb? Seems like an insane number.

But ... it's Apple. Apple product buyers are used to being gouged out the arse for money.

I had no idea you could get 512gb of ram. That’s ludicrous.
