Hans,
you have to re-install *all* packages whenever you upgrade R. R only guarantees
compatibility between patch versions (i.e. upgrading from R 4.0.0 to 4.0.1 does
not require re-install, but from R 4.0.0 to R 4.1.0 does). That was always the
case on all platforms, it's not new.
Note that the R Mac GUI makes the upgrade easier - in the Package Manager you
can select to install package from previous R version if you use the system
location. Otherwise you can always use simply
install.packages(rownames(installed.packages("path-to-old-library")))
Cheers,
Simon
