[OS X TeX] Why does TeXShop want to re-build pdflatex format (and fail)

[jfbu]

Hi,

I downloaded TeXShop 3.92, and I had this issue:

TeXShop reports it tried to build a the pdflatex format
and failed: it fails to find pdflatex.ini

Although I don't know the root cause, I know the
triggering circumstances: it is because I have my
TeXLive configured with an extra

/usr/local/texlive/2017/bin/x86_64-darwinmacports

repertory alongside the

/usr/local/texlive/2017/bin/x86_64-darwinlegacy

and the texbin (from my  /Library/TeX/Distributions/TeXLive-2017.texdist)

was pointing to the darwingmacports.

When I reset this symlink to target the default
x86_64-darwinlegacy all is fine with TeXShop.

It seems there is something hardcoded in TeXShop 3.92
which makes it believe that format needs to be rebuild
when the texbin points to

/usr/local/texlive/2017/bin/x86_64-darwinmacports

Error console:

Additional info:

I see in the preferences

kpsetool -w -n latex tex

and if I try manually

$ kpsetool -w -n latex tex pdflatex.ini
/usr/local/texlive/2017/texmf-dist/tex/latex/latexconfig/pdflatex.ini

it appears ok.

Notice also that the above seems to try to create the
format in my $HOME, if it had succeeded it could have
caused problem when I later update TeXLive and the formats
are recreated system-wise.

Best,

Jean-François
