All Mac Users Wanted try the new design and new features of Safari which Apple presented at WWDC. Tab groups, a more streamlined and unified look with the web pages themselves … the difficulty for many is that in order to test this right now you need to install the beta of macOS Monterey with all the commitments that entails. .
However, there is a much easier way to install this new Safari on macOS Big Sur: We can download the Technology Preview for Developers version that Apple makes available to the public from its website. Being a separate instance of the browser, we do not put any of our data at risk.
Download Safari Technology Preview … and you’re done
The first thing we need to do from this website is install Safari Technology Preview for macOS Big Sur. To distinguish it clearly, it is the purple icon. If you are not clear, you can use this direct download link. Be careful, this version of the browser is in English and it will not work on macOS Catalina or any other old version of the system.
When you have downloaded the installation file, you just need to open it and follow the given steps. Once you’re done, you’ll have the Technology Preview version of Safari in your Applications folder and you can use it like any other browser.
All the settings you make in this Safari, by the way, they will not harm what you have in the standard version and stable browser. You can play with whatever you want: create groups of tabs, check the behavior of those tabs and the browser interface … that can be a good “training” for when the change comes next September.
