2014 iMac with 8Gb RAM, useful again after installing Linux Mint
I got this 2014 iMac for free, with 8Gb RAM and 1TB Fusion Drive, running macOS 11 Big Sur. It was being given away for free by someone at work. It had belonged to their dad but gave it away after upgrading. The iMac is in great shape physically. I took it in because I figured I could play around with it as a home media server. I did use it like that for a few months, but it was really, really slow, sometimes taking several minutes to reboot or launch an app. Spinning beach ball seemed to be the main operating mode. Plus since it’s capped at macOS 11, a lot of newer apps won’t install or work. So I lost interest, stopped using it, and it started gathering dust.
Yesterday I was rearranging things to prepare for a house guest, and I rediscovered the old iMac. I figured, what the heck, got nothing to lose, let’s install Linux Mint on it and see if it runs any faster or more usefully. So I booted up from a live image of Linux Mint XFCE “Zena” erased the internal 5400 RPM HDD, and installed it.
Wow, I was super impressed. It felt like Linux Mint breathed new life into this 12-year-old iMac. First of all, Linux Mint + Firefox takes up only around 30 percent of RAM, so there is actually room to do things without paging to the very slow hard drive. I was able to install TailScale and connect it to my TailNet. I installed NoMachine and connected via Remote Desktop to a headless Ubuntu 24.04 LTS Homelab that’s running my home Jellyfin server. The iMac is still no speed demon, but certainly now much more responsive to the point where it’s actually useful. I can sit in my home office and use the iMac to monitor my server, play videos and music, cycle through pictures from my local photo library. It’s gone from doorstop to desktop, and I’m feeling quite pleased with the project.
