Simon, Thank you for the quick response!

When I asked this question, I was worried about the backwards compatibility issues arising from the new security model enacted on 10.14/10.15 that caused installer signing problems in R 3.6.3. > 3. not at all.

As an added benefit, it is the last version with support for NVIDIA eGPUs. Regarding Travis, I'll update the build script here with the new changes. https://github.com/travis-ci/travis-build/blob/ab196aed5b227288a2f4dcb5c7822868b430b110/lib/travis/build/script/r.rb Best, JJB On 4/1/20, 4:03 PM, "Simon Urbanek" <simon.urba...@r-project.org> wrote: JJB, 1. correct, there was too much trouble in this.

As I said, 10.13 is already way too high, in fact we picked it precisely so we don't need to change it for several years. Just to make sure we're clear - it's ok to use Catalina to build binaries for let's say macOS 10.11, so it's not about what system you use to build. It is about who is able to use the resulting software. The current R builds are actually running on Catalina. Thanks for your offer, it would be very helpful. Travis would be a good start - it needs command line tools, GNU fortran from https://github.com/fxcoudert/gfortran-for-macOS/releases/download/8.2/gfortran-8.2-Mojave.dmg the binaries from http://mac.r-project.org/libs-4/ and there is actually a machine-readable list in http://mac.r-project.org/libs-4/INDEX and R from http://mac.r-project.org/high-sierra/R-4.0-branch/R-4.0-branch.pkg Thanks, Simon > On 2/04/2020, at 2:30 AM, Balamuta, James Joseph <balam...@illinois.edu> wrote: > > Simon, > > Thanks for the overview!

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).
