Well, it's all about TeXShop:

% mdls -name kMDItemContentType -name kMDItemContentTypeTree -name kMDItemKind near-field-paper-part-1.tex
kMDItemContentType     = "edu.uo.texshop.tex"
kMDItemContentTypeTree = (
    "edu.uo.texshop.tex",
    "public.text",
    "public.data",
    "public.item",
    "public.content",
    "public.plain-text",
    "org.tug.tex"
)
kMDItemKind            = "TeX File"

What's even weirder is that the file seems to have a com.apple.LaunchServices.OpenWith attribute, and this also points to TeXShop:

% xattr -p -l com.apple.LaunchServices.OpenWith near-field-paper-part-1.tex
com.apple.LaunchServices.OpenWith:

Despite that, the icon was BBEdit.

To be sure, I've reinitialized the Launch Services database using

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

rebooting afterwards for good measure.

After that, .tex files have switched to the TeXShop icon. For how long?

It would be hard for me to ditch BBEdit. I first heard about it in the early 1990's, at the same time as Alpha, then used the freeware BBEdit Lite for some time and switched to the full shareware BBEdit in 1993. I have kept purchasing new versions more or less continuously ever since.

It's one of the few Mac OS applications of that time that has been continuously developed, fully embracing Carbon then Cocoa, 32-bit then 64-bit, always playing by Apple's guidelines regarding programming and user interface, however inconsistent the evolution of these guidelines may have been at times.

I'm mostly using its file and directory comparison, its single- and multi-file search, and its "zap gremlins" (to get rid of invisible non-ASCII characters which sometimes result in TeX warnings or errors). Its one-click EOL and encoding conversions too.
