Changelog

macrtools 0.0.8

Breaking changes

• is_xcode_cli_installed() now reports whether the Command Line Tools package is installed, rather than whether it is the selected developer directory. Use developer_dir() or is_xcode_toolchain_usable() to ask about the selection.

• is_xcode_app_installed() now reports whether any Xcode is installed anywhere, rather than whether /Applications/Xcode.app is selected.

• xcode_cli_switch() takes path as its first argument, where password used to be.

New features

• Added support for macOS 27 (Golden Gate).

• xcode_toolchains() lists every developer directory xcode-select can be pointed at, with its version and whether it is active.

• is_xcode_toolchain_usable() reports whether a compiler is reachable through the active developer directory, which is what decides whether R can build a package.

• developer_dir() resolves the active developer directory, honoring DEVELOPER_DIR.

• xcode_cli_version() reports the installed Command Line Tools version.

• xcode_cli_switch() gained a path argument, so a toolchain from xcode_toolchains() can be selected instead of always forcing the Command Line Tools.

Bug fixes

• Xcode is detected outside its default location. Both predicates compared the active developer directory against a hardcoded path, so a versioned bundle such as /Applications/Xcode_16.4.app reported nothing installed and triggered a needless softwareupdate run.

• macOS 27 is recognized as supported. The version ceiling is exclusive, so the previous bound rejected every 27.x release and aborted macos_rtools_install(), gfortran_install() and openmp_install().

• macOS versions ending in .0 compare correctly. sw_vers reports only two components for those releases, which placed each one in the previous release’s range: "12.0" read as Big Sur, "11.0" matched nothing, and "10.13" was rejected as unsupported.

• xcode_cli_install() no longer skips installation when an unselected Xcode exists elsewhere on disk, since it provides no compiler.

• macos_rtools_install() reports which toolchain is active instead of assuming a full Xcode, and reports a failure rather than success when nothing can compile.

• macos_rtools_uninstall() no longer reports a component as removed when it was not installed.

• The Command Line Tools version no longer comes from xcode-select --version, which reports the version of xcode-select itself.

• recipes_binary_install() documentation now states that the darwin repository is chosen by Darwin kernel version, not macOS version. The two are no longer a fixed offset apart.

macrtools 0.0.7

Features

• Added support for R 4.6.0 on macOS.
  • gfortran continues to use the universal GNU Fortran 14.2 installer (unchanged from R 4.5).
  • On Apple Silicon, R 4.6 (macOS 14 Sonoma and higher) installs the recipes binaries from the new darwin23/arm64 repository. The repository is detected automatically and installs to the same /opt/R/arm64 prefix as before, so no path changes are required.
• Updated the bundled LLVM OpenMP runtime from 19.1.0 to 19.1.5 to match the current release on https://mac.r-project.org/openmp/. The 19.1.x runtime covers Apple clang 1700.x and up (Xcode 16.3 through Xcode 26.x, the R 4.6 Apple Silicon toolchain), so existing systems remain correctly matched.

Internal

• Centralized the supported R version window behind minimum_supported_r_version() / maximum_supported_r_version() and replaced the repeated is_r_version("4.x") || ... chains with range checks (is_r_version_at_least(), is_r_version_supported()). Supporting a future R release that keeps the existing toolchain is now a one-line change.
• gfortran_update() now requires “R 4.2 or above” (matching its documentation) rather than an explicit, hard-coded list of versions.

macrtools 0.0.6.2

Features

• Added support for macOS Tahoe (26.x).
• Fixed the macOS version check so Tahoe (26.x) is recognized as supported. (#28)

macrtools 0.0.6.1

Features

• Added openmp_*() to install the LLVM OpenMP library for macOS. (#10)
  • openmp_install() to install the OpenMP library and set flags in ~/.R/Makevars.
  • openmp_uninstall() to uninstall the OpenMP library and set flags in ~/.R/Makevars.
  • openmp_test() for detailed overview of OpenMP install.
  • is_openmp_installed() to check if the OpenMP library is installed.

Bug Fixes

• Fixed macrtools::macos_rtools_install() erroring during the summary portion.

macrtools 0.0.6

Features

• Updated to support R 4.5.0 on macOS.
  • Downloads and sets up the latest version of gfortran 14.2

macrtools 0.0.5

Features

• Updated to support macOS Sequoia (15.0.0)

macrtools 0.0.4

Features

• Updated to support R 4.4.0 on macOS.

Deployment

• GitHub Actions now tests the package on release and next versions of macOS R’s version.

macrtools 0.0.3

Breaking change

• We’ve loosened the requirement to have Xcode CLI installed. The package will now accept if you have the Xcode.app IDE installed.
  • Note: The Xcode.app IDE requires significantly more space compared to Xcode CLI. We highly suggest that you install Xcode CLI.

Features

• Added is_xcode_app_installed() to check to see if the full Xcode.app IDE is present.
• Added xcodebuild() to understand properties about the Xcode.app IDE installation.

Changes

• Updated the supported version of macOS to macOS Sonoma (14.0.0).
• Improved the error message when the version of macOS is not supported.
• xcode_cli_install() and macos_rtools_install() have been modified to skip the installation of Xcode CLI if the full Xcode.app IDE is detected.

Documentation

• Switched describing the ARM Mac entries from M1 or M2 to M-series to generalize with how Apple names software.
• Improved details regarding the paths being chosen for software installed.

Deployment

• Updated the GitHub Actions for both R-CMD-check and pkgdown.

macrtools 0.0.2

Features

• Support the toolchain compilation requirements for 4.3.z series
• Updated the gfortran binary to the universal v12.2 Fortran installer across both Intel and arm64 platforms.
  • The gfortran path placed into ~/.Renviron is now /opt/gfortran/bin/gfortran.
• Recipes now supports the darwin20/x86_64 version (macOS 11) for Intel.
  • New installation directories for recipes downloads are given as:

Name	Installation Location	Target
darwin17/x86_64	/usr/local	macOS 10.13, Intel (x86_64)
darwin20/arm64	/opt/R/arm64	macOS 11, Apple M1 (arm64)
darwin20/x86_64	/opt/R/x86_64	macOS 11, Intel (x86_64)
