I am trying to install MiKTeX on a new macOS system. Each time that I try to compile any .tex file, I get the following error:

jwalsh23@Jacks-MacBook-Pro-14 $ pdflatex CV.tex
This is pdfTeX, Version 3.141592653-2.6-1.40.24 (MiKTeX 22.1) (preloaded format=pdflatex.fmt)
 restricted \write18 enabled.

Sorry, but pdflatex did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

  /Users/jwalsh23/Library/Application Support/MiKTeX/texmfs/data/miktex/log/pdflatex.log

The specified logfile contains the following:

I have tried reinstalling MiKTeX several times, running miktexsetup cleanup, I've tried using an admin installation as well as a user installation, nothing seems to work.

    any particular reason to be using miktex here? the vast majority of mac users will be using mactex (texlive) so easier to get help when things go wrong. May 18 at 23:16

    Welcome to SE. I wouldn't choose MikTeX as a distribution for macOS, honestly. If someone else can't help you find what specific problem you have, I'd recommend installing MacTeX instead.

  • you need to find out, why the format can't be created. There should be a log for it in one of the roots (on windows I have them in ....\AppData\Local\MiKTeX\2.9\miktex\log\makefmt\pdflatex) May 19 at 7:19

I have run into this problem once when I update the MiKTeX. Finally, I figured it out that You have to give "miktex console" administrate authority. The solution is:

run you "MiKTeX Console.app", then choose operation mode as administration mode instead of user mode, update packages and so on.

Then, the app should work as before.
