For me it was around this time in 2017. I had already ditched Windows for Mac around 2011-2012, but my work machine was getting long in the tooth and I realized I could get twice the power for half the cost if I switched to linux. A few months later I built a linux desktop for home use. A couple more years and I put linux on my 2013 Air.
Are we the same person? I also switched to macOS in 2011 and to Linux on Desktop in 2017, although I used Linux every once in a while parallel to Windows before. I also have a 2013 Air currently running Ventura with OpenCore, but I gave it to a family member a few years ago. Works well.
