Tips & Tricks

Troubleshooting, how to install safari technology preview on mac.

Safari Technology Preview is an optional web browser for Mac that is separate from the regular Safari browser, with the Tech Preview offering an early look at upcoming web technologies and features before they become included in the primary Safari browser. In this way, Safari Tech Preview is kind of like Google’s Chrome Canary, and it’s worth a look for many users.

Many web developers and designers may benefit from checking out and using Safari Tech Preview on their Mac, but a lot of casual users may enjoy the experience as well. Plus, Safari Tech Preview can run alongside regular Safari, and has full iCloud feature access, so you’ll have access to all your bookmarks and favorites too.

How to Install Safari Tech Preview on Mac

• Go to https://developer.apple.com/safari/resources/ and locate “Safari Technology Preview”

• Choose the download for your particular version of macOS
• When finished downloading, go to your Downloads folder and mount the SafariTechnologyPreview.dmg file, then run the bundled installer

• Launch Safari Technology Preview from the /Applications folder, or through Spotlight, or Launchpad

The Safari Tech Preview icon is purple, whereas the standard Safari icon is blue.

Updates for Safari Tech Preview are offered through the regular Software Update mechanism, and if you like it enough you can set it to your default web browser as well.

Personally I like to use Safari Tech Preview for development and design work, but also as an alternate browser for when my primary Safari app is over utilized with too many open tabs and windows, but I’m not in a position to close those out for work or personal reasons. I also use Chrome and Firefox for similar purposes, but I typically fall back to Safari for performance reasons, and it’s nice to have two Safari options available.

Do you use Safari Technology Preview? Do you have a particular use case? Share your thoughts in the comments.

Amazon GameLift now includes containers support (Preview)

Posted On: Apr 24, 2024

We are excited to announce that Amazon GameLift now supports containers for building, deploying, and running game server packages. Amazon GameLift is a fully managed service that allows developers to quickly manage and scale dedicated game servers for multiplayer games. With this preview release, GameLift now supports end-to-end development of containerized workloads, including deployment and scaling on-premises, in the cloud, or hybrid configurations.

Containers package up the entire runtime environment - all the code, dependencies, and configuration files needed to run the game server. With containers, game developers can seamlessly move game server builds between their local machines for testing, staging environments, and production deployments on-premises or in the cloud without worrying about missing dependencies or configuration drift. Containers also allow efficient use of resources by running multiple isolated game servers on the same host machine. Overall, containerization simplifies the deployment process, enables consistent, secure environments, and optimizes resource utilization for game server builds in the cloud or on-premises data centers.

Container support is available in preview in all Amazon GameLift regions, except AWS China Regions. Visit the Amazon GameLift containers support documentation to learn more and get started today.

I'm always curious about these Safari Tech Preview posts. Are they just a quick way to add another headline? I suspect so, as I don't see many people trusting these builds as their daily driver. I've tried that in the past, but it never stuck.
