TeXShop adds the .tex extension automatically to every file it saves, unless you have selected something else in the File Format pull-down menu of the Save dialog:

By default this extension hidden, as can be seen (and changed) by selecting the file in the Finder and going to File > Get Info in the menu bar (or typing Command-I):

Alternatively, this can be changed in Terminal by deleting the com.apple.FinderInfo extended attribute, as in

	xattr -d com.apple.FinderInfo Test.tex

This makes the extension visible.

The above is Cocoa code, from Mac OS X (ie, originating from NeXt). There's also a deprecated Carbon way, namely code dating back to the Mac OS Classic days of the last millenium. To check whether an extension is hidden, you can use say

	GetFileInfo -ae Test.tex

which returns "0" if the extension is visible and "1" if it is hidden. Then,

	SetFile -a E Test.tex

hides the extension and

	SetFile -a e Test.tex

makes it visible.

xattr is part of macOS, whereas GetFileInfo and SetFile come with Xcode or the Command Line Tools. See also

	https://superuser.com/questions/399899/show-hide-extension-of-a-file-through-os-x-command-line

Finally, I don't know whether TeXShop can be set to make the extension visible by default when saving a file.

Hope this helps,
