I updated day one and had usual apple problems (finder broke so I had to use my terminal, sometimes it wouldn't wake up from sleep so I had to force it to reboot, my fans would spin up for seemingly no reason). Most of the issues were fixed a week later or so.
Anyway, I recently switched to Arch on a 2018 LG Gram and I'm not really missing anything. Battery life is great (8-12 hours of Firefox) and it has a quad core x64 processor for non-browser things.
Yeah, same. I couldn't stomach the port situation on the new macbooks (and the High Sierra issues) so ended up with a 4th gen Lenovo Carbon X1. Wiped Windows 10 and installed Mint. The whole process was dead-simple and I couldn't be happier with it.
Thanks for mentioning the LG Gram. I actually didn't know LG sold laptops (they're not available in Canada) before your comment. I just ordered one online now! I insta-purchased it when I noticed the 2018 model still has USB 3 Type-A and HDMI ports. Ctrl-key in the corner instead of Fn-key and equal sized arrow keys are a bonus.
Fits my needs as a Macbook Pro replacement. Will be running linux desktop on it too. Probably elementary OS.
