As time progresses, so does the advancement of technology. More so in the personal computing space, which has seen a massive shift in recent years. We’re seeing wildly powerful (and efficient!) computers, but that power has also left older hardware entirely in the dust.
Despite being older, much of this hardware is more than capable of handling basic day-to-day tasks, but the gap is starting to widen. Ordinarily, most of these older machines cannot run modern operating systems such as Windows 11 and macOS Tahoe reliably (if at all), which makes us turn toward Linux as our savior once again.
While Linux has always been a bit friendlier toward lower-end hardware, you really can’t address physical limitations entirely. In my case, it was an old MacBook Air (11-inch, 2012) with a measly 4GB of system RAM.
Most mainstream distributions are a complete no-go with just 4GB of RAM, but thankfully, we do still have a few options. These specialized distros cater to lower-end systems, and I went through three before ultimately picking a winner.
These 5 lightweight operating systems can make any slow PC fast
Don’t let aging hardware force you into buying expensive upgrades.
The laptop in question
Four gigabytes of RAM in 2026?
The laptop I used to test these 4 Linux distributions on was a MacBook Air (11-inch). This particular variant comes with a 2-core i5-3317U and 4GB of on-board, non-upgradeable RAM. It has the Intel HD Graphics 4000, which takes some of that anemic 4GB for itself.
There’s no USB-C, although it has a Thunderbolt port — that I’ve found no use for, yet. On top of that, this machine runs painfully slowly even on Ventura with OpenCore. macOS is not an option, and modern Windows is too bloated.
Linux comes forward as a natural choice here, but those 4GB of RAM are going to be a huge bottleneck, more so than the CPU itself. This makes popular options like GNOME or KDE poor picks, as do gamer-focused distros.
MX Linux
A better antiX
Described as a cooperative effort between the antiX and MX Linux communities, MX Linux is built on top of Debian Stable. As such, it targets stability and supports a wide range of older devices. If you’re looking for something that’s a bit more bleeding edge, you might want to look elsewhere.
Interestingly, MX Linux also offers a KDE desktop, though I decided to go with Xfce instead, since KDE could be a bit of a resource hog in this situation. One installation later, and I was in the customized Xfce desktop.
There’s not a lot to look out for or even describe, other than the fact that MX Linux is pretty functional and performant. It’s also a lot more intuitive, which I can’t say the same for artiX.
RAM usage hovered over the 1 GB mark, which is a bit higher than I wanted it to be. All things considered, it’s more than usable, and doesn’t feel too bare bones.
Linux Mint Xfce edition
Old but gold
Mint took a bit of time to install. If you’re looking to do the same, make sure to select Compatibility Mode from the installer, or the live environment might not work properly.
Still, things felt a bit off. The entire desktop felt sluggish until I decided to update the system. This is yet another friendly reminder to keep system updates timely, since they can make a world of difference.
After a long update process, I was greeted with the Mint-flavored Xfce desktop. Much unlike the vanilla Xfce install, this has been riced significantly. Still, it’s the same old DE we’ve come to appreciate over the years. Xfce is lightweight and still well-supported.
Cinnamon might have been a prettier choice, but it is a bit more resource-hungry and a poor choice for this setup. Xfce just flies past and is a breeze to use.
antiX Linux
Performant but convoluted
Installing antiX was a nightmare. It refused to boot off my Ventoy drive, so I had to flash it manually onto another USB drive. Once I was booted into the installation medium, I proceeded to install it onto the MacBook’s internal drive.
After a failed attempt (with zswap being the culprit), I finally managed to get antiX installed. One reboot later, and I entered the kind of underwhelming antiX desktop.
AntiX targets absolute potato hardware, and has a no-frills approach to its interface as well. It’s extremely stripped down, and runs on top of IceWM. IceWM is weird. There are a lot of strange defaults, which make it puzzling to navigate.
That being said, I never ran into performance issues with antiX. The system ran at a casual 300MB of system RAM and felt snappy.
Unfortunately, it wasn’t stable at all, and I couldn’t get the system to update using Wi-Fi or Ethernet. As such, I’ll hesitate to recommend antiX for now.
Arch Linux
You control the packages you install
It really shouldn’t be too surprising to learn that Arch Linux would end up on this list. It’s snappy and offers full user control. In other words, I could choose my display manager, apply performance tweaks, and use a custom kernel, which is not possible with a predefined distro such as AntiX.
Using the handy Archinstall script, I ended up with an Xfce desktop. I had my doubts at first, but after some basic testing, I was pleasantly surprised by how hiccup-free the whole experience was.
By contrast, ArtiX was very unintuitive and even a bit buggy. Going back to Arch, the 4 gigabytes of RAM didn’t seem to slow the MacBook Air down at all. Yes, part of it has to do with the swap file and the use of a more performant Zen kernel, but the whole machine performs miles better than macOS ever did.
Not to mention, it is also up to date, and the hardware support has matured enough that even a vanilla install would suffice. Everything just works, but you can always tweak things further to squeeze a bit more performance.
Your mileage will most certainly vary
I won’t sugarcoat it — the laptop works fine, but it is severely gimped thanks to those 4GB of RAM. Modern browsers eat a ton of RAM, and something like Chrome is not a good idea.
As long as you limit yourself to the stock apps and desktop environment, you should be (mostly) fine. If you try to push the machine hard, it won’t keep up and will struggle spectacularly.
If you have a reasonably specced laptop, you should have a better time. If Apple can pull off 8GB of system memory with the MacBook Neo, Linux can too. Just make sure to stick to minimal, bloat-free installs, and don’t do anything too crazy, like compiling a kernel.
