No, it is an old Mac (2018, laptop), so I am  unsure why good old tlmgr ought to be confused.

I transferred the updated 2019-tree (some 8GB!!) from the desktop (Mojave) which updated it 
and I just verified the 2019-tree works  on both short and very very long projects (like a 655 page book).

So, I am unsure whether I realy take up astrology to know when to update on what (using tlmgr) or whether
a clear advise be issued on tlmgr along the lines “folks, this (tlmgr) does not work on Big Sur before TL 2020” and, "do NOT let this software attempt to update your pre-2020 trees even if it offers to”.

That might save some aggravation for those of us who did not write this (tlmgr) code and just naively attempt to use it thinking “it works". We are mostly users after all and we will believe everything the developers (do not) tell us.

Good advise that ought to be visible outside this forum!

Cheers,
George
