I have tested an R-4.0.0 (i.e. R version 4.0.0 alpha (2020-04-01 r78130)
with my two packages (nleqslv and geigen) and all my private tests.
I have not found any problems with checking and testing these packages.
(I used Apple clang and Coudert's gfortran 8.2)

The only issue I have encountered is:

The R GUI hangs when I click "What's New In This Version" in the Help menu item.

However, the build fulfils Apple's conditions and is known to pass notarization (in fact the the package available for download today is actually notarized) so it should be a good test for the release which will be notarized and should work on Catalina.
> For those that want to replicate our setup - technical details: we are now building with macOS 10.13 (High Sierra) as target (i.e. the oldest supported system), regular Apple Xcode/command line tools and GNU Fortran 8.2. R builds are running on macOS 10.15 (Catalina) with Xcode 11.4 using macOS 10.13 target. Packages are built on macOS 10.13 VMs with just Apple command line tools (this should make it easy to replicate the setup using Travis, for example). All 3rd party libraries that CRAN uses are available in http://mac.r-project.org/libs-4/
