I can not confirm this. I am a long time LyX user in production (I seem to have switched from OpenOffice to LyX in 2005 according to what I can find in my operating reports directory), regularly updating LyX and MacOs, and on an number of different boxes (from iMini via the trashcan MacPro to a 5k iMac) and laptops (12 and 13 inch airs).
The only issue I am having sometimes is LuaLaTeX being 3 times slower than pdfLaTeX but of course it is the future :-)-O and there are many ways around some of it. Is there a way of measuring the startup time of a Mac application? greetings, el On 22/08/2019 19:08, Chris Menzel wrote: [...] > I'm not really a Windows user either, but I got so irked with recent > Mac laptops that I bought the (quite lovely) Dell in a fit of pique. > I have to say that, once you get it set up right, LyX under Windows > (and Linux) works rather better than it does under macOS.
