<div dir="ltr">Hi,<div><br></div><div>Is this by any chance on an Apple-silicon laptop? I was helping a colleague recently install MacTeX on his shiny new MacBook Air and I believe I encountered a similar problem. In my case, I got past the problem by setting the paper size in the TeXLive utility. This seems to force the .fmt files to be created. After that, everything was fine. Seems strange, but this was my experience --- perhaps this will help out in your situation also.</div><div><br></div><div>Bill Slough</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Aug 22, 2021 at 12:42 PM "M.

First I thought it was TeXShop, but running latex from terminal also throws an error:<br>

I deleted and reinstalled MacTeX and TeXShop, but still have the error. I guess I am stymied as well. Any assistance would be appreciated.<br>
