If you had 32G RAM it would use that too. It uses all it can. 8GB is fine. And will be for years.

macOS will pop up a window that says the system has run out of application memory, asking you to quit applications. I have a friend with, I believe a base M3 Air, who runs into this constantly with nothing but Firefox open.

(Been trying to get them to switch to Safari, but they prefer the Firefox name. I don't think there's anything wrong with Firefox other than it being less native.)

Does Safari use less RAM because it shares some parts with the rest of the OS? (e.g. in the same way Edge probably uses a bit less because half of its components are already idling on the OS)

You could say that. WebKit is in the dyld shared cache, so all of Safari's subprocesses share the same copy of it (and JavaScriptCore, etc.) in memory. But I would say it's more efficient because it integrates better with the platform's QoS primitives. I'm not sure what Firefox does in that regard, other than stuff from other platforms that don't have QoS (such as the throttling of JavaScript APIs like timers). Safari seems better at prioritizing the tabs you have open and backgrounding everything else, letting things go to swap, killing resource hogs, etc.

I have an M2 Air 24GB/1TB that has been such a beast that I haven't touched my 16" Pro in months. I have four browsers running, with a ton of tabs in Brave (daily driver) and I'm sitting at 21/24GB utilization with all sorts of apps running (granted, Docker is not at the moment, but it still doesn't make it sweat). I had ~8 pro laptops in a row going back to the late 2000s, but Apple Silicon has changed how I work. A future 14" OLED that was similarly light might turn my head, but if I had to replace it today I'd just buy another M5 Air with at least this much RAM. [FYI I never installed Chrome after M1 came out. Brave has been rock-solid for over a half-decade now.]

24GB is definitely solid. 16GB is like my minimum recommended for any kind of Mac, but if you can go for more you should go for more. I think 24GB should last a good long while though.

16GB, depending on your use, can be constraining and, sometimes, you need to get creative with complex processes. My colleagues complain about developing with several containers running peripheral services. In similar situations we asked the services teams to provide mocks that answered the same APIs without needing a large memory footprint.

In the article, Gruber normally uses a 64GB Mac, expected the 8GB RAM to be a problem and was surprised to find that it wasn’t, and judged the Neo as not being a bad experience in any way.

Gruber has also had it for a week at most by the time he published his review. It’s enough time to run some tests, not enough time to properly review what it will be like to actually live with it. I like the guy, but I also understand the limitations of how he reviews products.

8GB can be limiting on an iPad Pro, which runs a generally more memory efficient branch of Apple’s XNU-based system software and it’s not difficult to get it into a state where it is constantly paging out an app you had in front of you two minute ago if anything you’re doing involves the web at all. A Mac will just swap at that point, but swapping is also slow.

You could get away with 8GB 5 years ago and you still can do it now, but Macs are expected to last longer than that, and starting now with 8GB might become limiting 5 years from now. Here we retire them at about 10 years, or when the last OS they can run is EOL’ed.

Not to be devils's advocate here, but I'd suspect Apple is aiming for a smaller retirement window for this kind of product.

It's basically a Laptop engineered in the iPhone/iPad space of the company, it's only natural for Apple to target a shorter lifecycle.

8GB RAM is maybe the best way to achieve that, many of the MacBook Neo buyers of today will be very compelled to upgrade to a newer (or higher-tier) model in ~3 years from now...

If the Neo would have 16GB of RAM today, it would be harder to justify an upgrade in 3 years from now, when the common entry-tier for laptops is likely still at 16GB...
