I've received an 11 years old #Macbook Air (Intel Core i5, 4 GB RAM, 128GB SSD) which was super sluggish and is not supported by Apple for a few years already. Yesterday I installed a #Fedora Kinoite on it instead of the macOS. There was only one hiccup: Fedora doesn't ship non-free broadcom wifi driver, and Macbook Air doesn't have Ethernet port.
Long story short, I got it working after understanding a little bit more about OStree and RPMFusion.
Soon will release a short blog post about it 馃
