Hi All,

Relevant for TeX users on macOS, as happens around this time of the year, M=
acTeX has been updated to use TeX Live 2020:

  http://www.tug.org/mactex/

One major change this year, as a result of Apple's requirement to now use a=
pp notarization on Catalina, is that the TeX Live Utility (TLU), as a GUI i=
nterface for updating the TeX distribution contents, is no longer included =
in the MacTeX distribution.

If you install MacTeX 2020, you will find a file called "MISSING APPS.pdf" =
in the Applications/TeX folder, that describes this, and which also affects=
 BibDesk and cocoAspell, albeit, I have not searched for info on the latter=
 two apps.

Based upon some searching for TLU info, I found the following issue on Gith=
ub:

  https://github.com/amaxwell/tlutility/issues/85

which makes it clear that the TLU author has no confirmed plans to update t=
he app to support notarization. This is apparently due to his essentially n=
o longer using TeX himself, he is still running High Sierra (10.13), the co=
st of becoming an Apple developer in order to notarize the app and related =
philosophical considerations.

The TLU is otherwise available for manual download as a DMG file here:

  http://amaxwell.github.io/tlutility/

however, the DMG has not been updated since January 24, with some pending, =
unreleased updates, as of this writing.

It is not clear if the TLU author may, at some point, be convinced to take =
the steps to notarize the app, perhaps with financial support from some par=
ty (e.g. TUG), or may just orphan the app, where somebody else may move it =
forward or perhaps develop something entirely new to replace it.

That all being said, there are CLI commands that can be used to maintain/up=
date the TeX distribution. These are described here:

  http://www.tug.org/texlive/pkginstall.html

and where there are essentially two commands to use:

  tlmgr update --list

which will list the pending updates, and:

  tlmgr update --all

which will install the pending updates. You will likely need to run these a=
s an Admin (e.g. using sudo).

Since the TLU supported scheduled update checks, you could feasibly run the=
 CLI commands in a cron job, but would otherwise need to remember to run th=
ese periodically, if you wish.

Regards,

Marc Schwartz
