Correct. I often have hundreds of browser tabs open on my iPhone, but it knows how to manage resources by unloading the ones I'm not looking at right now. The Mac can also swap tabs or apps to disk. Or warn me when I hit 90%. The
only wrong option is to start freezing when it's too late. I'm a software developer who has been coding for decades, and I'm surprised by this failure mode. What would a random non-techie need to learn to reason about this? It's not like Macs are marketed only to technical professionals who keep an eye on resources.
Look, at least the Apple is smart enough to wake up basically in the same window state after having refreshed the resources. That's fantastic. But even better to fix it without going through the whole "have you turned it off and on again" routine.
