It is a package that installs the TeX binaries and configuration files, none of which will show up in your Applications directory. (They are mostly in /Library/TeX.) LyX should know where they are and call them (with no input from you) when you try to view or export a document.

download BasicTeX from the MacTex site. And then use tlmgr from the<br class="">
command line to install missing packages individually. Before an update<br class="">
it is trivial to save the list of installed packages so that one can<br class="">
re-install them afterwards.<br class="">
<br class="">
I bought me a 32Gig 4TB MacBoc 13" Pro (BtO) the other day and a 16Gig<br class="">
2TB 12" Air for travel.<br class="">
<br class="">
If you can wait a year of two I would wait a year or two :-)-O<br class="">
and then get the biggest M1 13 inch you can then afford (BtO).<br class="">
<br class="">
greetings, el<br class="">
