I can't speak for Macs. But in the Linux world, 8GB is fine. In Windows it's awful because of all that bloat. I'm guessing Macs fair better for OS efficiency.
Macs don't have copilot so that's like 4GB saved right there
Ha ha ha. True!
8GB of ram is more than fine for work and medium photo/video editing, as long as you have plenty of SSD space and don’t use Apple Intelligence.
People forget that MacOS is UNIX at its core.
I'm running Mint on an 8GB laptop and I'm surprised by just how much can be running at one time. Right now I'm running Firefox with 10 open tabs, Waterfox with 8 tabs, Thunderbird, Keepass, Calibre, Signal, a Whatsapp client, Syncthing, Libreoffice Writer with 2 open docs & Calc with 2 open small spreadsheets, a couple of terminals and Gedit, and didn't even notice it until came across these comments. A friend who uses Windows 11 says 32GB is recommended now.
Microsoft must be thrilled with age verification being required at the OS level. What a great way to lock people into their Microslop garbage.
Oh......I guess I'm the only one who opens firefox, and literally thousands of tabs.
One day I closed one window and it said "Are you sure you want to close 158 tabs?"
I said yes. It was one window. I had 23 more windows.
When I get to 20 or so I have to start closing some tabs to keep track of things. How do you find the tab you're looking for when you have that many open?
Tab search.
Tab groups.
Color coding.
I use sideberry addon on Firefox and workspaces in Vivaldi.
Zen (firefox (gecko) derivative, No AI, focus on decluttered interface) has bloody excellent tab management these days, workspaces, folders, horizontal tab lists (like sideberry), essentials (tab icons pinned to the top), auto unload, all built in, and everything disappears when reading a page.
Glance is the most used feature on Zen for me. Everything else I like Firefox for more, but that damn Glance feature really helps me when doing research or looking into things! I NEED it for Firefox! :'(
Literally thousands? Have you tried bookmarking things after they've sat unused for awhile?
I typically just periodically save my browser windows with a tab manager extension. I just say because thousands sounds like way too much to keep track of...
I rarely have more than 10 tabs open on my phone, and rarely more than 5 in my PC. How do people have so many tabs?
Get Sideberry for your sanity.

I literally have over a thousand tabs open in one window.
8Gb ram. Mint. 10+ year old pc.
Yeah sidebery is the goat. I too have thousands of tabs open.
This is the computing equivalent to hoarding.
I’m running Arch on a Macbook Air with 2GB of RAM. Its limited, but it does what I want it to.
Many entry level MacBooks of the last decade have probably been 8 GB. I have a M1 MacBook Air and that is 8 GB. It is fine for me.
So I presume you're saying that the entire system shouldn't slow down when Firefox starts swapping?
I use mainly Linux but Mac is more efficient with RAM than Linux is also. By a significant amount.
What?
I use OSX for work and Linux on my personal laptop, that hasn't been my experience at all
There are some advantages macOS can have but it depends on usage patterns and user knowledge:
Dynamic swap and zswap aren't really the same as efficient ram usage it's just good ways to mitigate when you run out. But when your using actual swap it's in my experience more noticable on OSX than Linux, which at least for me remains responsive until you're using a lot of swap.
Maybe Arch & Flatpak users hit this, but avoiding multiple versions of the same library is what distros exist for and avoiding loading different frameworks is what Desktop Environments are for. Although the ability to restore apps after closing them is pretty sweet and built in to OSX in a way that lets me safely kill apps to reduce the memory I'm using.
I think the main reason my Linux setup consumes less memory is probably because I used Kate for most file editing instead of vscode, which is probably an unfair advantage to Linux.
I disagree. If the OS automatically identifies unneeded pages and compresses them or swaps them out, it’s certainly using the physical memory more efficiently than if it wasn’t doing these things.
But they can’t if the applications they want to ship don’t all use the same version. E.g. Ubuntu ships GTK 2, 3, and 4. Arch even still ships GTK 1 in addition to these three.
What happens is you run KDE but then you still want to run Firefox so you still need GTK.
MacOS doesn't shove the system UI components into swap when Firefox uses too much memory.
To clarify, some versions of Linux are lighter weight with resources, and macOS does tend to take up more RAM at rest to make things pull up snappier, if you have it to spare. But their compression algorithm is better, and if you are using near the limit, it will be more efficient with the use of the RAM you have available before lagging. With Windows and Linux, it feels more like if you're out of RAM you're out if RAM. It's less likely to happen at all on Linux though.
It is not more efficient. Macs use more ram in general and they both employ memory compression and caching.
The only time I ever use more than 8gb on my M4 Mac Mini is when I run a Win 11 VM through Parallels
