Sudden problem with Texshop

[Paulo Ney de Souza]

Dear Mr. Bruschi,

I would appreciate being referred to as just Paulo Ney, my first name.

Adding to what Richard said, he should be the point man here:

I believe it does not have much to do with TeXShop, except for
the fact that TeXShop and all the programs it calls may imply high
memory use. Probably the same would happen if you called Maple
of Mathematica and tried something hard to compute in it.

If your machine has or is developing some kind of memory problem,
the symptoms will be very close to what you describe.

I would recommend testing your RAM with Apple's user diagnostics
tools is easy. Simply restart your Mac, and then hold down D as soon
as it restarts. If you did it correctly, your computer will either boot into
Apple Diagnostics or Apple Hardware Test, depending on the age of
your machine.

Apple silicon Macs require a different way of entering Apple Diagnostics.
You must first shut the Mac down and turn it back on, holding down the
Power button until you get to the startup options screen. Then, press Cmd +
D.

Follow the prompts and let the test complete.

Best,
Paulo Ney
