[OS X TeX] Latest TeXLive 2020 updates are killers

[Murray Eisenberg]

As reported by Tine Wilde in a previous message here, so for me things have gone very wrong since the latest updates (via TeXLive Utility): a book-length document using the memoir document class chokes on the preamble.

In response to my post https://tex.stackexchange.com/q/565360/13492 <https://tex.stackexchange.com/q/565360/13492>, “egreg” replied that an update to memoir (specifically, to memhfixc.sty) didn’t get added to CTAN yet but should be available soon.

So if Tine Wilde’s document used memoir, perhaps that will fix things.

Not knowing how long it will be before the memoir update becomes available — or whether, in fact, that will cure all the ills of the 2020-10-03 LaTeX updates, I’m tempted to re-install TeXLive 2020. BUT…there have been some crucial updates to packages since the original appearance of TeXLive 2020. So..

How might one revert to an earlier version of the TeXLive 2020 system _and_ do all updates EXCEPT those around October 1 that broke things?
