Dated April 20th, v13.2 (105) may already have been downloaded and installed on your Mac. Apparently, its late posting here is MU catching up. - - For me, the Technology Preview series has been a way for me to keep Safari v12.1.2 (which has far superior extensions available, including the must-have brilliant uBlock Origin (whose developer gave up on Apple when Safari 13 was foisted upon us), while being able to play around with Safari 13.x. - - The awful, abysmal extension selection for v13.x remains its profound failing, yet another clobberingly stupid Apple Bungle, so common over the last 4 years. /rant

The description at the top of the MacUpdate page says this is also available for MacOS Sierra (10.12) but if you go to Apple's website it only provides links for 10.13 and 10.14. The download link on MacUpdate for 10.12 is for release 49 and it hasn't been updated in pretty much a year now.

And now we're at v73! Again, until Apple get their lagging butts in gear, it is HIGHLY recommended to use Safari Technology Preview and NOT regular Safari due to a published exploit present in ALL of version 12.0.x. These latest betas have solved the exploit. Why Apple hasn't formally updated Safari is beyond comprehension. I'm starting to think of the word 'irresponsible' at this point.

Safari Technology Preview is now at v72 (aka compiled Safari v12.1 beta, WebKit 14607.1.17.1). It is highly recommended over regular Safari v12.0.2 as it includes a critical security hole patch.

IMPORTANT! Release 71 (Safari 12.1, WebKit 14607.1.15) is the current version of Safari Technology Preview as of December 5, 2018. This version is particularly important because all previous versions of Safari 12 (up through 12.0.2) have a vulnerability currently called "WebKit-RegEx-Exploit", for which a PoC, Proof of Concept, has been published. IOW: If you demand maximum Safari security, you MUST upgrade to this current version of Safari/WebKit. More about the exploit is published here: https://www.bleepingcomputer.com/news/security/webkit-vulnerability-affects-latest-versions-of-apple-safari/ The page providing the most current Safari Technology Preview is: https://developer.apple.com/safari/download/

There seems to be an issue with the bookmark drop down menu. maybe it's how it's being drawn, maybe not. but the app freezes anytime I try the bookmark menu. No issues with any other Safari or browser. Can't use it as it is now.

Getting there, still lags behind other browser in HTML 5 compatibility though. According to html5test.com: Firefox scores 466/555 Chrome scores 507/555 Safari Technology Previews scores 416/555 For reference, current version of Safari only scores a 383/555 - so the TP is an improvement, but still a long ways to go.

My experience -- Release 19 (Safari 10.1, WebKit 12603.1.14.2) Search bar bug for me. Type in the search term "executable" and the latest Safari Preview crash instantly and every time while typing. This is not the case for other search terms however. Have submitted a bug report to Apple. Otherwise prior Safari Technology Preview versions have worked fine. The problem occurs with all extensions off or on. No difference.

Release 9 (Safari 9.1.2, WebKit 11602.1.41), works very well and is noticeably faster than the regular (Version 9.1.2 (11601.7.7). The extensions I use are working fine: AdGuard, Ghostly, Shortly, PriceBlink, and a few others. The recent Previews seem to manage memory and sleep background windows and tabs better.

Some issues with Cookie Version 5.0.10 (or could be with Cookie itself).

(This on a MacBook Pro retina, and images look fine. I haven't used on a non-retina.)

Unlike what users with a serious Apple hangup (Helmo Hass) who misuse the Discussions page, I have found nothing wrong with the Safari Technology Preview application. It's significantly quicker than regular Safari, imports bookmarks just fine, and has the access to the Keychain as well. Like most things from Apple, it just works. That being said, I have only been using it for a little while, and it works great.

Well, guys, maybe you're not familiar with beta or nightly builds. There is no point installing them and using them unless you're willing to experiment with whatever's implemented (detailed in the release notes) and ready to face whatever bugs you will experience. New features needs testing before being implemented in a future stable release. All your complaints are simply related to the fact you are using an unstable preview release of a browser and therefor is irrelevant. Clauclau, 1. & 2. the preview uses a different profile, that's protecting your primary and default one. 3. Since it is a different profile, of course it doesn't sync with the default. 4. Installing a beta system is an all different concept from installing a browser beta, a frontend developer (for example) might want to experiment with a beta browser without having to install and deal with an unstable system, that's the point. Helmo Hass Seems like you have a problem with Apple that goes way beyond a browser preview release, an all different subject. About your BTW paragraph, same as above, different profile is way better than using your default one, guess you would have been complaining if it did mess something up in it anyway.
