Hi Hans, I didn't have time on Saturday night to implement your solution so when I got back to it on Sunday I saw their was an update which I decided to install. However it came up with an error on installation as follows:  lua error       > lua error on line 48 in file mlib-ctx.mkxl: token call, execute: ...m64/tex/texmf-context/tex/context/base/mkxl/mlib-msh.lmt:45: attempt to index a nil value (local 'contour') stack traceback: ...m64/tex/texmf-context/tex/context/base/mkxl/mlib-msh.lmt:45: in local 'code' ...m64/tex/texmf-context/tex/context/base/mkiv/util-lua.lua:97: in field 'loadedluacode' ...m64/tex/texmf-context/tex/context/base/mkiv/luat-env.lua:108: in field 'luafilechunk' ...m64/tex/texmf-context/tex/context/base/mkxl/luat-cod.lmt:82: in field 'registercode'         [ctxlua]:1: in main chunk <empty file> I left it till today and decided to do a complete reinstall is case I had mucked something up, but I still got the same error. Could you have another look please? If you need the full terminal output on installation from my M1 mac mini, let me know, it's about 300kB. I have ConTeXt on an old windows laptop which I use as a backup and it updated successfully. Thanks and Best Wishes Keith On 05/07/2025 18:57, Keith McKay wrote:

not the latest binary ... i didn't check the build for that ... but it looks like that mac is off line

in the meantime:

ua error : function call: ...ata/contextmacosarm64/tex/texmf-osx-arm64/bin/mtxrun.lua:6673: attempt to index a nil value (field 'mesh')

in that mtxrun.lua file go to those lines and comment the mesh bit or replace it with

     local mesh = vector.mesh

     if mesh then

         local ismesh  = mesh.ismesh          local totable = mesh.totable

         setinspector("mesh",function(v)              if ismesh(v) then                  inspect(totable(v))                  return true              end          end)

     end

do the same at the end of l-math.lua in order to be able to make a format.

If Mojca gets the machien online i'll update. Sorry for the problem,

Hans

ah, same issue ... that code expects the latest bin

the good news is that Mojca figured out why the mac didn't compile so i can now make a new bin
