If your computer does not support Dell SupportAssist OS Recovery, Dell provides operating system recovery image for Windows, Ubuntu, or Linux that was factory installed on your computer. You can download and use the Dell operating system recovery image to perform a clean installation, or reinstall Windows, Ubuntu, or Linux on your Dell computer. The Dell OS recovery tool provides an interface to quickly download and create a bootable USB drive to reinstall the operating system.
The Dell OS Recovery Tool helps you download the operating system recovery image that is customized for your Dell computer and create a USB recovery media. The Dell OS Recovery Tool allows you to download either Microsoft Windows, Ubuntu, or Linux operating system recovery image that was preinstalled on your Dell computer.
Yes. The Advanced Mode in Dell operating system Recovery Tool allows you to create a USB recovery media using an operating system image file in ISO file format. This is useful if you downloaded the operating system recovery image using a Linux, Mac, or Android device.
Typical operating system recovery image files in an ISO file format are between 5-16 GB in size (the file size varies between different operating systems). Once the file is downloaded, the Dell operating system Recovery Tool verifies the integrity of the file before creating the USB recovery media. The time to download and verify that the integrity of the file can vary depending on network speed and file size.
If you download a large file through a Dell online application (such as the Dell operating system Recovery Tool), you may receive a "Not enough space on drive" error. This is due to a space limitation on the hard drive where the files are being saved to. Some operating system recovery images can be up to 16 GB in file size.
The operating system recovery image may not contain the latest device drivers for your Dell computer. The latest device drivers are available at Dell.com/support/drivers. After the operating system is installed, Dell Technologies recommends that you download and install the latest device drivers.
If you are using the Postman web client, you will need to also download the Postman desktop agent. The Postman agent overcomes the Cross Object Resource Sharing (CORS) limitations of browsers, and facilitates API request sending from your browser version of Postman. Read the blog post.
If you want to be first in line to experience new features, download our latest Canary builds available for OSX (Intel and Apple chips) / Windows (x64) / Linux (x64) for a sneak peek. Our Canary builds are designed for early adopters, and may sometimes break.
For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms.
or, in many cases, public keys can also be foundat keybase.io.On the version-specific download pages, you should see a link to both thedownloadable file and a detached signature file. To verify the authenticityof the download, grab both files and then run this command:

This directory contains binaries for a base distribution and packages to run on macOS. Releases for old Mac OS X systems (through Mac OS X 10.5) and PowerPC Macs can be found in the old directory.Note: Although we take precautions when assembling binaries, please use the normal precautions with downloaded executables.
Package binaries for R versions older than 3.2.0 are only available from the CRAN archive so users of such versions should adjust the CRAN mirror setting ( -archive.r-project.org) accordingly.R 4.2.2 "Innocent and Trusting" released on 2022/10/31 Please check the integrity of the downloaded package by checking the signature: pkgutil --check-signature R-4.2.2.pkg in the Terminal application.

R 4.2.2 binary for macOS 11 (Big Sur) and higher, Apple silicon arm64 build, signed and notarized package. Contains R 4.2.2 framework, R.app GUI 1.79 for Apple silicon Macs (M1 and higher), Tcl/Tk 8.6.12 X11 libraries and Texinfo 6.8. Important: this version does NOT work on older Intel-based Macs - see below for Intel version.Note: the use of X11 (including tcltk) requires XQuartz (version 2.8.1 or later). Always re-install XQuartz when upgrading your macOS to a new major version.This release uses Xcode 13.1 and experimental GNU Fortran 12 arm64 fork. If you wish to compile R packages which contain Fortran code, you may need to download GNU Fortran for arm64 from -project.org/tools. Any external libraries and tools are expected to live in /opt/R/arm64 to not conflict with Intel-based software and this build will not use /usr/local to avoid such conflicts (see the tools page for more details).

The latter two components are optional and can be ommitted when choosing "custom install", they are only needed if you want to use the tcltk R package or build package documentation from sources.Note: the use of X11 (including tcltk) requires XQuartz to be installed (version 2.7.11 or later) since it is no longer part of macOS. Always re-install XQuartz when upgrading your macOS to a new major version.This release supports Intel Macs, but it is also known to work using Rosetta2 on M1-based Macs. For native Apple silicon arm64 binary see above.Important: this release uses Xcode 12.4 and GNU Fortran 8.2. If you wish to compile R packages from sources, you may need to download GNU Fortran 8.2 - see the tools directory.
