Safari technology preview old version5/30/2023 You’ll find both the current beta version of Safari (developer membership required to download) and Safari Technology Preview (no membership needed) available for download. Getting the Safari Technology Preview browser is simple enough just point your current web browser to the Apple Developer Safari Download page. How to Get, Install, and Update Safari Technology Preview If you want to try out specific advanced web features, or you’re a web developer who needs modern, advanced developer tools, then STP may be a good candidate to add to your collection of browsers.Īnd since STP doesn’t interact with your other browsers, there’s no reason not to have it installed on your Mac just for those days when you want to fiddle around with an experimental web site or two. If you use your Mac primarily in a mission-critical workflow, I advise staying away from any betas, including the Safari Technology Preview browser. We’ll cover the Experimental Features menu a bit later suffice it to say, the more features you enable, the less stable the browser could become. On the other hand, STP is a beta app, and while it is known to be very stable, that stability can change from version to version, as well as by which experimental features you enable. (STP will usually be faster than Safari, as shown in this Speedometer benchmark.) The Safari Technology Preview browser has the potential to be one of the fastest available browsers for the Mac, so if speed is an issue, you should definitely try out STP. It really depends on your needs and browsing habits. STP Bug Reporter not only allows you to report bugs you encounter, but you can also make enhancement and feature requests.Independent of the standard version of Safari, you can run STB and Safari side-by-side, with no interaction between them.If you’re a web developer, STP contains a wide collection of developer tools.It allows you to try out the latest web technology.You can discover more by stopping by the Safari Technology Preview developer’s page (developer membership is not required). Safari Technology Preview contains many additional features and capabilities, way too many to list here. (STP gained Dark Mode support in release 71.) WebRTC: Web Real-Time Communication is an open-source standard that allows audio and video communications to work within a web page using direct peer-to-peer communications.WebMetal: Similar to WebGPU but specific to the Metal-enabled GPUs used in some Macs (mostly 2012 and later models).WebGPU: A future standard, still being worked on, that allows a computer’s GPU to be used to accelerate rendering of both 2D and 3D graphics images within the browser. Dark Mode support: Safari gained support for Dark Mode in Mojave.Apple is testing the Client-to-Authenticator protocol part of the FIDO2 standard that would allow a hardware key, in this case in the form of a USB stick, to be used in place of passwords as a login credential for web services. Web authentication using USB security devices: This set of programming APIs allows USB-based security devices to be used for authenticating login credentials.In addition, STP can translate older CSS animation to the newer and faster web animation standard. Web animation: STP gained support for Web animation, part of the W3C standard.In the two most recent updates (STP 71 and STP 72), Safari Technology Preview has seen new additions to its list of experimental features: (Web animation can be used to bring life to a web page, or simply to animate a galaxy of swirling points of lights.) Likewise, new technologies that are being developed are likely going to be first publicly seen in STP, at least for Mac users, and updated frequently with each STP release.Ī better question would be, what are the recent features since STP is updated so frequently. Second, frequent updates ensure that bugs, once found, are quickly fixed. With all these new or updated components, you would think STP would be prone to errors and crashes, but in actual use, Safari Technology Preview remains very stable, a testament to the developers and the testing process being used with this beta browser. It could also have a new or updated JavaScript engine, updated CSS technology, new features, developer tools, and security measures. At any time, STP may be running an updated version of WebKit, the rendering engine that powers Safari. Think of it as a public beta for the next generation of the Safari browser, but with a few important differences over conventional beta software.įirst off, STP is amazingly stable, which is a pretty amazing thing to say for an app that is, at its heart, a framework for Apple to plug in modules to test out various concepts. STP was designed as a testbed to evaluate new browser technology that Apple is considering using in future releases of Safari. Safari Technology Preview, often referred to as STP, is a web browser for the Mac.
