This free Linux distro is the easiest way to revive your old computer. How it works
Briefly

After failing to install Linux Mint on an aging Intel MacBook, a user successfully switched to Linux Lite. The installation performed well, despite an initial issue with keyboard layout. Linux Lite is praised for being a unique lightweight Linux distribution that is straightforward yet allows customization of the Xfce desktop environment. The author noted its fast performance even on low resources, making it suitable for older hardware. Overall, Linux Lite stands out in the lightweight category for both usability and efficiency.
"Linux Lite was fast. I gave the virtual machine I used 3GB of RAM and two CPU cores, and this distribution performed as if it had four times that power."
"They tend to be fairly generic, with a lack of eye candy and panache. They get the job done and not much more."
