Jan 03, 2017 Mac users running macOS Sierra 10.12.2 are being urged to avoid using Preview to edit PDFs until Apple fixes several bugs in the app that can cause corruption issues in the document format.
Jun 20, 2016 Launch the MacOS Sierra Installer from the /Applications/ folder on the Mac, it is currently labeled as “Install 10.12 Developer Preview.app” Go through the installer as usual, when you get to the disk selection screen, choose “Show All Disks” and choose “Sierra” from the list, then click on “Install” to begin installing MacOS. /Install 10.12 Developer Preview.app does not appear to be a valid OS installer application. Can you help with this Posted. The runtime is used to run apps created with.NET Core. When an app author publishes an app, they can include the runtime with their app. If they don't include the runtime, it's up to the user to install the runtime. There are three different runtimes you can install on macOS: ASP.NET Core runtime Runs ASP.NET Core apps. Includes the.NET Core.
-->In this article, you'll learn how to install .NET Core on macOS. .NET Core is made up of the runtime and the SDK. The runtime is used to run a .NET Core app and may or may not be included with the app. The SDK is used to create .NET Core apps and libraries. The .NET Core runtime is always installed with the SDK.
The latest version of .NET Core is 3.1.

Beginning with macOS Catalina (version 10.15), all software built after June 1, 2019 that is distributed with Developer ID, must be notarized. This requirement applies to the .NET Core runtime, .NET Core SDK, and software created with .NET Core.
The installers for .NET Core (both runtime and SDK) versions 3.1, 3.0, and 2.1, have been notarized since February 18, 2020. Prior released versions aren't notarized. If you run a non-notarized app, you'll see an error similar to the following image:
For more information about how enforced-notarization affects .NET Core (and your .NET Core apps), see Working with macOS Catalina Notarization.
libgdiplus
.NET Core applications that use the System.Drawing.Common assembly require libgdiplus to be installed.
An easy way to obtain libgdiplus is by using the Homebrew ('brew') package manager for macOS. After installing brew, install libgdiplus by executing the following commands at a Terminal (command) prompt:
Install with an installer
macOS has standalone installers that can be used to install the .NET Core 3.1 SDK:
Download and manually install
As an alternative to the macOS installers for .NET Core, you can download and manually install the SDK and runtime. Manual install is usually performed as part of continuous integration testing. For a developer or user, it's generally better to use an installer.
If you install .NET Core SDK, you don't need to install the corresponding runtime. First, download a binary release for either the SDK or the runtime from one of the following sites:
- ✔️ .NET 5.0 preview downloads
- ✔️ .NET Core 3.1 downloads
- ✔️ .NET Core 2.1 downloads
Next, extract the downloaded file and use the
export
command to set variables used by .NET Core and then ensure .NET Core is in PATH.To extract the runtime and make the .NET Core CLI commands available at the terminal, first download a .NET Core binary release. Then, open a terminal and run the following commands from the directory where the file was saved. The archive file name may be different depending on what you downloaded.
Use the following command to extract the runtime:
Use the following command to extract the SDK:
Tip
The preceding
export
commands only make the .NET Core CLI commands available for the terminal session in which it was run.You can edit your shell profile to permanently add the commands. There are a number of different shells available for Linux and each has a different profile. For example:
- Bash Shell: ~/.bash_profile, ~/.bashrc
- Korn Shell: ~/.kshrc or .profile
- Z Shell: ~/.zshrc or .zprofile
Edit the appropriate source file for your shell and add
:$HOME/dotnet
to the end of the existing PATH
statement. If no PATH
statement is included, add a new line with export PATH=$PATH:$HOME/dotnet
.Also, add
export DOTNET_ROOT=$HOME/dotnet
to the end of the file.This approach lets you install different versions into separate locations and choose explicitly which one to use by which application.
Install with Visual Studio for Mac
Visual Studio for Mac installs the .NET Core SDK when the .NET Core workload is selected. To get started with .NET Core development on macOS, see Install Visual Studio 2019 for Mac. For the latest release, .NET Core 3.1, you must use the Visual Studio for Mac 8.4 Preview.
Install alongside Visual Studio Code
Visual Studio Code is a powerful and lightweight source code editor that runs on your desktop. Visual Studio Code is available for Windows, macOS, and Linux.
While Visual Studio Code doesn't come with an automated .NET Core installer like Visual Studio does, adding .NET Core support is simple.
- Download and install Visual Studio Code.
- Download and install the .NET Core SDK.
- Install the C# extension from the Visual Studio Code marketplace.
Install with bash automation
The dotnet-install scripts are used for automation and non-admin installs of the runtime. You can download the script from the dotnet-install script reference page.
The script defaults to installing the latest long term support (LTS) version, which is .NET Core 3.1. You can choose a specific release by specifying the
current
switch. Include the runtime
switch to install a runtime. Otherwise, the script installs the SDK.Note
The command above installs the ASP.NET Core runtime for maximum compatability. The ASP.NET Core runtime also includes the standard .NET Core runtime.
Docker
Containers provide a lightweight way to isolate your application from the rest of the host system. Containers on the same machine share just the kernel and use resources given to your application.
.NET Core can run in a Docker container. Official .NET Core Docker images are published to the Microsoft Container Registry (MCR) and are discoverable at the Microsoft .NET Core Docker Hub repository. Each repository contains images for different combinations of the .NET (SDK or Runtime) and OS that you can use.
Microsoft provides images that are tailored for specific scenarios. For example, the ASP.NET Core repository provides images that are built for running ASP.NET Core apps in production.
For more information about using .NET Core in a Docker container, see Introduction to .NET and Docker and Samples.

Use Siri on the Mac, Access Your Desktop from Anywhere, Copy and Paste Between Devices & Rediscover Favorite Memories in Photos
San Francisco — Apple today previewed macOS Sierra, a major update to the world’s most advanced desktop operating system, with new features that make the Mac smarter and more helpful than ever. Siri is now on the Mac with brand-new capabilities to help with the things users do every day on their desktop. With Siri, users can look up information, find documents, pin or drag and drop search results, and even adjust system preferences. Seamless integration with iCloud makes everything from your Desktop and Documents folder available on your iPhone and iPad so you always have access to the files you need. Universal Clipboard allows you to copy content, including text, images, photos and video from one Apple device and paste it in another. Apple Pay comes to the Mac in Sierra so it is even easier to shop securely and privately online. And Photos now helps you rediscover your meaningful memories, organize your library and perfect shots like a pro.
“macOS Sierra is a major update that makes your Mac smarter and more helpful than ever with improvements to the apps you know and love and great new features throughout,” said Craig Federighi, Apple’s senior vice president of Software Engineering. “With macOS Sierra, you can get information, find files and multitask using Siri, access your Desktop and Documents from anywhere, copy and paste between Macs and iOS devices, and rediscover precious memories in Photos.”
Siri Debuts on the Mac
Mac Os 10.12 Developer Preview Download
Siri on the Mac is now just one click away. The familiar features of Siri are now on the Mac with brand-new capabilities specifically designed for the desktop. Easily accessible from the Dock, menu bar or keyboard, Siri lets you use your voice to search for information, find files and send messages. For example you can ask Siri to locate a specific document you worked on last night, add a meeting to your calendar or start a FaceTime call. With Siri on the Mac, you can also drag and drop items from Siri search results into your documents or emails, pin Siri search results in Notification Center to keep an eye on information like sports scores or stock prices, and even adjust system preferences, set reminders and search your Photos library. With its debut on Mac, Siri is now on all four Apple software platforms — iOS, macOS, watchOS and tvOS — and handles two billion requests per week across 36 countries.
Your Desktop and Documents on All Your Devices
With macOS Sierra you can automatically have all the files on your Desktop and in your Documents folder on any Mac, iOS device or even PC. You simply save your files on your Desktop or within your Documents folder as you usually do and you will have them everywhere you need them. You can access your files on your iPhone and iPad in the iCloud Drive app and on iCloud.com or the iCloud for Windows app. And when you log into a second Mac, your files are automatically on the Desktop and in the Documents folder, exactly where you saved them.
Copy and Paste Between Devices
Continuity across your Apple devices also gets better in macOS Sierra. With Universal Clipboard, the contents of your clipboard are available across all your Apple devices via iCloud. You can easily copy and paste text, images, photos and video between your Mac and your iPhone and iPad.
Tabs in Almost Every App
To help you navigate your Desktop with more efficiency, macOS Sierra takes the popular Tabs feature from Safari and makes it available across Mac apps that support multiple windows, including Maps, Mail, Pages, Numbers, Keynote and TextEdit, and even third-party apps. With Tabs you can browse multiple locations in Maps without losing your place, copy and paste between Pages documents in full screen, or quickly jump between multiple email drafts in Mail.

Picture in Picture on the Mac
You can now keep an eye on one thing while working on another. macOS Sierra lets you float video from Safari or iTunes in a window over your desktop as you work, and even resize, drag and pin video to any corner of your screen. The video stays put when you switch spaces, so you’ll never miss a thing.
Shopping on Your Mac with Apple Pay
Users love to shop online using their Macs and with macOS the shopping experience in Safari is now even better. Apple Pay on the web makes it easy to make secure and private purchases when shopping on participating websites. You no longer need to share credit or debit card numbers with an online merchant and actual card numbers are not stored on your device, nor on Apple servers. Just look for the Apple Pay button at checkout on many of your favorite shopping sites and complete your purchase with Touch ID on your iPhone or by using your Apple Watch. Strong encryption protects all communication between your devices and Apple Pay servers, and Apple Pay does not track your purchases.
Rediscover Memories with Photos
The new Memories feature in Photos helps you rediscover favorite and forgotten moments deep in your Photos library by automatically creating curated collections of occasions like a first birthday party, wedding or family vacation. With new advanced computer vision, Photos now understands the people, places and things inside your images using on-device facial, object and scene recognition and location information to group images into albums. The People feature automatically groups your photos into Albums based on who is in them. Places now displays your photos on a world map so you can see where they were taken. And, perfecting your photos like a pro is now even easier with the new Brilliance tool, which pulls in highlights and adds contrast to enhance details throughout your images.
Additional macOS Features
- Auto Unlock lets you simply walk up to your Mac while wearing your authenticated Apple Watch and be automatically logged into your desktop.
- Optimized Storage frees up space when your Mac starts getting full by storing infrequently used items in iCloud and reminding you to delete used app installers, and even clearing out duplicate downloads, caches, logs and more.
- Messages makes conversations more interesting, now allowing you to preview web links and watch video clips within the app, post reactions like a heart, thumbs up and more directly onto a message bubble with Tapback, and use bigger emoji for more message impact.
- Apple Music in iTunes makes it even easier to discover new music and browse exclusives and new releases.
Privacy in macOS
Security and privacy are fundamental to the design of Apple hardware, software and services. iMessage and FaceTime use end-to-end encryption to protect your data by making it unreadable by Apple and others. Services like Siri and Maps send data to Apple’s servers, but this data is not used to build user profiles, and Photos uses on-device intelligence to organize your images using facial, object and scene recognition.
Starting with macOS Sierra, Apple is using technology called Differential Privacy to help discover the usage patterns of a large number of users without compromising individual privacy. In macOS Sierra, this technology will help improve autocorrect suggestions and Lookup Hints in Notes.
Availability
The developer preview of macOS Sierra is available to Apple Developer Program members at developer.apple.com starting today. Mac users can sign up for the macOS Sierra Beta Program today and download the software starting in July at beta.apple.com. The final version will be available for free from the Mac App Store this fall. For more information, visit apple.com/macos/sierra-preview. Features are subject to change, and some features may not be available in all regions or all languages.
