Safari is the best way to see the sites on iPhone, iPad, and Mac. Thanks to blazing-fast performance and industry-leading energy efficiency, hundreds of millions of users enjoy exploring the web with Safari. Take advantage of powerful new features, advanced developer tools, and cutting edge technologies in Safari to deliver the best-in class websites and apps.
Apple Pay on the Web
Give customers an easy and secure way to make purchases in Safari 10 or later. Apple Pay allows customers to quickly pay without entering payment, shipping, or contact information on supported websites from their Mac, iPhone, or iPad. Because card numbers aren’t used and every transaction is confirmed with a fingerprint or passcode, Apple Pay is more secure than accepting credit and debit cards.
Picture in Picture
Now users can keep an eye on web video while they multi-task on Mac. Picture in Picture lets users float a video window from Safari over their desktop or full-screen app. Users can play video in any corner of their desktop and resize the window to see more or less of what’s behind it. The window stays put even if they switch desktop spaces. The default HTML5 video player in Safari automatically supports Picture in Picture. And if you use a custom video player, it’s easy to add a Picture in Picture control using the JavaScript presentation mode API.
Safari Extensions on the Mac App Store
The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community. Use Xcode to develop your extensions, with the option to get started using App Extension templates, and implement new capabilities using powerful native APIs and familiar web technologies. Xcode 12 supports the popular WebExtension API and includes a porting tool to make it easy to bring your extensions to Safari. And if you’ve already developed an app, you can give users access to your app’s functionality and content, right in Safari.
HTML5 and Legacy Plug-ins on macOS
To deliver faster load times, better battery life, and stronger security, Safari is optimized for HTML5, and will load this content whenever it is available. For websites that use proprietary formats, Safari supports the use of plug-ins such as Flash. In Safari 10, plug-ins are supported for websites where HTML5 is unavailable and may be enabled by users for each individual website. Users can choose to enable plug-ins for one session or every time they visit a specific website. For frequently-visited websites, enabled plug-ins will remain active. For infrequently-visited websites, plug-ins will be disabled.
Content Blockers on macOS
If you previously created Content Blockers for Safari on iOS, you can easily bring them to macOS. You’ll be able to distribute and sell Content Blockers through the Mac App Store. Just like the new Safari Extensions, Xcode makes it easy to create Content Blockers using App Extension templates.
Autoplay and Inline Video on iOS
To help users easily discover your video content, you can now autoplay videos and play them inline with other content on your webpages on all iOS devices. Safari supports autoplay on iOS devices for videos without sound, keeping down the number of distractions on the web.
Split View in Safari on iPad
Users can now view two websites at the same time on their iPad using Split View. Responsive Design Mode makes it easy to see how your websites will render in this view — just tap the iPad preview until it turns into a Split View.
Safari Technology Preview
Which Version Of Xcode For El Capitan
Download Safari Technology Preview to get a sneak peek at upcoming web technologies in macOS and iOS and experiment with them in your websites and extensions.
This directory contains binaries for a base distribution and packages to run on Mac OS X (release 10.6 and above). Mac OS 8.6 to 9.2 (and Mac OS X 10.1) are no longer supported but you can find the last supported release of R for these systems (which is R 1.7.1) here. Releases for old Mac OS X systems (through Mac OS X 10.5) and PowerPC Macs can be found in the old directory.
Note: CRAN does not have Mac OS X systems and cannot check these binaries for viruses.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 (https://cran-archive.r-project.org) accordingly.
R 4.0.4 'Lost Library Book' released on 2021/02/15
Please check the SHA1 checksum of the downloaded image to ensure that it has not been tampered with or corrupted during the mirroring process. For example type
openssl sha1 R-4.0.4.pkg
in the Terminal application to print the SHA1 checksum for the R-4.0.4.pkg image. On Mac OS X 10.7 and later you can also validate the signature using
pkgutil --check-signature R-4.0.4.pkg
Latest release:
| R-4.0.4.pkg (notarized and signed) SHA1-hash: 0b2b3bc846f6ebc72a8bc0b53e6e85d600d95deb (ca. 85MB) | R 4.0.4 binary for macOS 10.13 (High Sierra) and higher, signed and notarized package. Contains R 4.0.4 framework, R.app GUI 1.74 in 64-bit for Intel Macs, Tcl/Tk 8.6.6 X11 libraries and Texinfo 6.7. 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 since it is no longer part of OS X. Always re-install XQuartz when upgrading your macOS to a new major version. Also please do not install beta versions of XQuartz (even if offered). This release supports Intel Macs, but it is also known to work using Rosetta2 on M1-based Macs. Native Apple silicon binary is expected for R 4.1.0 if support for Fortran sabilizes, for experimental builds and updates see mac.R-project.org. Important: this release uses Xcode 12.4 and GNU Fortran 8.2. If you wish to compile R packages from sources, you will need to download GNU Fortran 8.2 - see the tools directory. |
