• A Great Support by AncientFamily Big thanks to All my DragonMembers of lavender and whyred.
• Universal GNU Fortran 4.2.3 for Mac OS X 10.4 and higher. It is necessary in order to build R packages from sources that contain Fortran code. Unlike many other builds, this is a fully universal build of GNU Fortran that uses Apple's driver and supports all target architectures (i386, ppc, x8664 and ppc64).

Development Tools and Libraries

CRAN R 4.0.0 builds and higher no longer use any custom compilers and thus this directory is no longer relevant. We now use Apple Xcode 10.1 and GNU Fortran 8.2 from https://github.com/fxcoudert/gfortran-for-macOS/releases.For more details on compiling R, please see alsohttps://mac.R-project.org/tools/

Previous tools

The following is provided as support of older versions of R. If you use R 4.0.0 or higher, please disregard and read the top section.

R 3.5.0-3.6.3 El Capitan binaries and higer were using more recent Clang compiler and GNU Fortran 6.1 to provide OpenMP parallelization support and C++17 standard features. If you want to compile R packages from sources, please download GNU Fortran binary from the official GNU Fortran Binaries page - in particular OS X 10.11 gfortran 6.1. Alternatively, we are providing a copy here as well as Clang binaries for OS X 10.11 and higher - see below for the download links.

Files:

clang-8.0.0.pkg (OS X 10.11+, signed, 64-bit) MD5-hash: 664582b0722cb59802cb762b2ad7548b (ca. 482Mb)	Clang 8.0.0 for OS X 10.11 and higher, release build for x86_64, signed package, installs into /usr/local/clang8. To be used with El Capitan builds of R 3.7.0 and higher. It is an installer version of the official LLVM released binaries only modified to use the path above.
clang-7.0.0.pkg (OS X 10.11+, signed, 64-bit) MD5-hash: cef3fd2a5c165d00f9941f64ea4024f7 (ca. 463Mb)	Clang 7.0.0 for OS X 10.11 and higher, release build for x86_64, signed package, installs into /usr/local/clang7. To be used with El Capitan builds of R 3.6.x. It is an installer version of the official LLVM released binaries only modified to use the path above.
clang-6.0.0.pkg (OS X 10.11+, signed, 64-bit) MD5-hash: c29700c4e7b2914073ef7e741eb105bc (ca. 418Mb)	Clang 6.0.0 for OS X 10.11 and higher, static build for x86_64, signed package, installs into /usr/local/clang6. To be used with El Capitan builds of R 3.5.x.
gfortran-6.1.pkg (OS X 10.11+, signed, 64-bit) MD5-hash: 201026216e8b373d9cd2efc0cc474bb8 (ca. 73Mb)	GNU Fortran 6.1 for OS X 10.11 and higher - a copy from GFortranBinaries pages for x86_64, signed package, installs into /usr/local/gfortran (identical content, re-packaged to a flat Installer package and signed). To be used with El Capitan builds of R.
The following binaries are obsolete and only provided for historical reasons
gfortran-4.2.3.pkg (OS X 10.5+, signed, 64-bit driver) MD5-hash: 8783f803038abe6487a362ad5b8995ea (ca. 27MB) gfortran-4.2.3.dmg (OS X 10.4, 32-bit driver) MD5-hash: 9551fc46f55537dd1db581154daf27ef (ca. 27MB)	Universal GNU Fortran 4.2.3 for Mac OS X 10.4 and higher. It is necessary in order to build R packages from sources that contain Fortran code. Unlike many other builds, this is a fully universal build of GNU Fortran that uses Apple's driver and supports all target architectures (i386, ppc, x86_64 and ppc64). As such it fully supports compilation into fat files like gfortran -arch i386 -arch ppc -arch x86_64 -arch ppc64 t.f -o ton both Intel Macs and PowerPC Macs (32- and 64-bit). Dependent libraries are fat as well, avoiding problems known from other Fortran builds (such as those from HPC). It installs in /usr/local and comes with an uninstall-script.
tcltk-8.5.5-x11.pkg (OS X 10.5+, signed) MD5-hash: e7c406d91762ffdc4539b23c5b5a3ab4 (ca. 9MB) tcltk-8.5.5-x11.dmg (OS X 10.4) MD5-hash: c32dda1b9f2c2776a02cec4e03befc76 (ca. 9MB)	Universal build of Tcl/Tk 8.5.5 for X11 (32-bit and 64-bit). This library is necessary in order to use the tcltk R package (for R 2.8.0 - 2.15.3 only!). It installs in /usr/local. Requires Mac OS X 10.4 (Tiger) or higher for 32-bit R and Mac OS X 10.5 (Leopard) or higher for 64-bit R. NOTE: R 3.0.0 and higher comes bundled with Tck/Tk 8.6.0 so you do not need this package

For other (optional) 3rd party libraries for development see http://mac.R-project.org/libs/. The devpack has been superseded by those libraries. For R you may want to download and install libpng, libjpeg, readline, freetype, fontconfig, pixman and cairo.

Source code for all 3rd party libraries can be found at http://mac.R-project.org/src/

The dependency libraries used by the CRAN macOS build system are now managed by build recipes. Package authors wishing to add static dependendies can create a pull request to add a dependency.

If you’re running into problems with your M1 Mac, you don’t need to panic and call Apple just yet. Like Intel Macs, your computer has a mode called “macOS Recovery” that you can use to run emergency maintenance on your Mac. However, the method is different for Apple silicon Macs, so the old keystrokes won’t work.

You may remember that you could get to Recovery on an Intel Mac by holding down Command-R on the keyboard as the Mac boots. Here’s how it’s done on an M1 Mac:

Lavender Link Mac Os 11

1. Turn off your Mac. As you power it back it on, press the power button and hold down the button while the Mac boots.
2. The screen will show icons of the bootable storage devices connected to your Mac, plus an Options icon. Select Options and click Continue. This puts the Mac into Recovery mode.
3. Enter your Mac’s admin password if prompted.

Then you’ll go to the Recovery screen, where you can choose from a selection of apps and perform certain maintenance tasks. You’ll also be able to reinstall macOS and run disk maintenance if needed.

Lavender Link Mac Os X

Fallback recovery OS

If that’s not working, M1 Macs actually have a second recovery mode that Apple calls “Fallback recovery OS.” As the name implies, this is another recovery mode you can use in case the regular macOS Recovery mode doesn’t work.

To boot into Fallback recovery OS, double-press the power button and hold down the button while your Mac boots. According to Apple’s Platform Security document, Fallback is “a second copy of recoveryOS that is kept for resiliency.” It offers the same options as Recovery, but doesn’t allow you to modify the system security state, which you can do in the regular macOS Recovery.
