Safari 15.1 Beta Now Available for macOS Big Sur and macOS Catalina

Apple on late Thursday seeded the first beta of Safari 15.1 for macOS Big Sur and macOS Catalina to developers for testing. Safari 15.1 beta is also included in the eighth beta of macOS Monterey seeded earlier this week.

The release notes for the Safari 15.1 beta are largely recycled from the initial release of Safari 15, but in our own testing, the beta appears to fix an issue where bookmarking a YouTube page would result in the browser crashing. Apple will likely be implementing additional bug fixes by the time Safari 15.1 is released to the public, but an issue with the browser showing old tabs upon being reopened does not appear to be fixed yet.

Safari 15.1 beta can be downloaded from the Apple Developer website on the More Downloads page when logged in. In order to install the beta, developers must be running the latest versions of macOS Big Sur or macOS Catalina, according to Apple.

Safari 15 features redesigned tabs that have a rounder and more defined appearance, faster performance, improved security, and more. The browser will come preinstalled on macOS Monterey when the software update is released later this year, and Apple has also made the browser available for macOS Big Sur and macOS Catalina users.

Is it just me, or is the shading of the new-style tab (buttons) counterintuitive. I find that with two tabs open, the lighter background-tab actually feels like it is the one in focus simply because it's clearer, and the darker tab feels like it should be representing the background page ...I say "representing" because of course, as they are now buttons rather than tabs there is no actual visiual connection. It's driving me mad!

YES. The tab design is awful. I'm constantly trying to select the wrong tab.

Fine Apple UX, they thought we were gonna love it.
Spot on. The new design not only looks bad, but also breaks established rules for interface design. The result is confusing and counterintuitive.

I’m still trying to figure out where this "faster performance" thing is. Safari 15 runs like a two-legged dog on my M1 mini.

Will not be installing Safari 15 any time soon. The sidebar designed by a clown in iPadOS 15 Safari is bad enough without ruining my Mac as well.
