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

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


repertory alongside the


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

Additional info:

I see in the preferences

kpsetool -w -n latex tex

and if I try manually

$ kpsetool -w -n latex tex 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.
