What is a Pro product? Jeffrey knows:
Pro should mean for professionals, but really Pro just means More. Or, More Expensive. Or, Top of the Line. How professionals use anything Pro from Apple varies too much to have a specific model named Pro.
Mac Pro is nothing like iPhone 11 Pro.
Pro means more. More what? That’s the issue. Pro could mean simply more money; a higher price tag, but in Apple’s case it means not only a higher price tag but better hardware specifications.
Pro means whatever Apple wants it to mean.
