Can you allocate a desired amount of RAM to an application? No. You own the hardware of your laptop, but you don't own its RAM usage.

RAM is the property of the operating system. Even if you put a lot of RAM, the operating system will not give it to you. The truth is significantly different today. Here is your mistake: 'The more RAM, the better the machine performs!' That is an urban legend dating from the MS-DOS days. And he, for his use case, was not only fine, but laughing. The list of apps he ran includes multiple virtual machines, multiple Adobe apps, Xcode, Office, and much, much more.

These included apps you'd find professional photographers, designers, software engineers, penetration testers, reverse engineers, and other types running – and I ran them all at once, and switched between them, making 'professionally-type-stuff' happen as I go. But even so, let's take a look at what it takes to really pin your MacBook Pro's memory, from a 'professional's' perspective.I fired up a bunch of apps and projects (more than I'd ever work on at one time) in every app I could possibly think of on my MacBook Pro. Ironically, many of the people saying that don't quite fall into what many others would consider a 'real pro' themselves at least based on the target demographic of Apple's 'pro' line, which has traditionally been geared toward working professionals such as photographers, producers, engineers, and the like (not managers and bloggers). Apple's latest MacBook Pro line is limited to 16GB due to energy (and likely heat) constraints, and that's gotten a lot of people complaining that it simply isn't enough for 'real pros'.
