macOS 15.7 & Safari 26 = laggy garbage

I had been happily running on Safari 18.6 on OS 15.7.5 and neglected to uncheck Safari 26.4 when I was updating the Developer Preview, so now I'm forced to run Safari 26.4. All of my original complaints still apply. What a load of bollocks.

So I guess they don't plan fixing it for MacOS 15, rather relying folks updating to MacOS 26 or iOS 26 through lapse of concentration of the default check boxes. The invasive push of notifications alone in iOS now occurs for me multiple times per week. As an Apple user since 2006, I cannot recall such an aggressive push to update as we're seeing now.
I forgot to add that I did try to roll back to Safari 18.6 with no luck. Like my other M4 with 15.75 that got Safari 26.x, the installer will run and then error at the very last step. Tried 4-5 times with the same result (including as root). So now I get to run borked Safari 26 on TWO 15.7.5 Macs. Ridiculous.

I've just tried on 15.7.5 and it works with Safari 18.6 for Sonoma

I recall you having reverted with the Air but the install failing back then on the other machine. So you accidentally updated to Safari 26 and this time round it's not "taking" on the Air either?
I wonder what's actually happening with your setup with both machines unable to downgrade. Just for reference, I used post#31 in this thread but from memory I think you've already been there...done that.
Correct. Now the Air won't "downgrade" to 18.6, just like the Pro. The Air was built from the Pro so there aren't any substantive differences that should cause it to fail the install. I should add that having used the Air almost exclusively since the errant 26.4 install, I'm prob at my 400th search for "wh" which used to reliably bring up a website I use 20 times/day. So seemingly trivial, yet SO F-IN ANNOYING.
That's the exact same package that previously worked on 1/2 Macs on 15.x and now works on 0/2 with 15.7.5.

I tried to installed Safari 18.6 on my 15.7.5 M4 MBP, it shows "The installation failed."
Could you please advise how to successfully install 18.6? Thanks

It worked just by double-click.
Another way: give Full Disk Access to Terminal and run:
Code:
sudo installer -verbose -pkg ~/Downloads/Safari18.6SonomaAuto.pkg -target /The command assumes Safari18.6SonomaAuto.pkg is in ~/Downloads

I tried to run the code in terminal and got the error : installer: The install failed. (The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance. An error occurred while running scripts from the package “Safari18.6SonomaAuto.pkg”.)
To double click the pkg file with below error too.
Sad to see Safari 26 apparently was and is disappointing. Happy to buy hardware under current CEO but rather upgrade software under the next 😉
Thank you. Installs ok. I will see how it goes. Intel (2019 iMac) macOS 15.7.5
Just tried on Sequoia 15.7.7 and an M2 MBA. Installs and runs fine using that Terminal code.
Thanks Bogdanw!
@bogdanw, Thanks for the concern. I use Brave as a first choice browser and have the latest Safari re-installed now. Was just testing that older version, to see if I could stand it. I actually have never been able to use Safari, as a first-choice browser, due to visual issues with its light grey on grey insistence. Apple's Tahoe has similar "hard for my old eyes to discern" menus and such. So I am trying to stay on Sequoia as long as possible.
Please do post any links you find to 15.7.7 as Apple makes them available.

Have you tried Orion? https://orionbrowser.com/platforms/macos The light/dark theme can be changed from the menu and customized to some extent.
Interactive script to get Sequoia installers links directly from Apple https://forums.macrumors.com/threads/experimental-no-tahoe-for-sequoia.2480020/post-34526677
I just tried that script in Terminal. Resulted in this error. "zsh: event not found: /bin/zsh"
Tried in Script Editor, error there too. Syntax error.
Thanks anyway.
As for Orion, I will try it later. For now, Brave works very well indeed on my MBA in Dark mode, no visual issues at all.
And it is often updated. New version in the works now (assets will be completed in 2 or 3 hours).

The full installer for macOS 15.7.7 (24G716) is now available.
New version of macOS 15.7.7 and a new version of Safari Version 26.5 (20624.2.5.18.3). I know the Safari update is mostly security fixes (lots of them!), but will see how it goes.
What hardware are you running? What extensions do you have?
Safari has become blazingly fast in the 15.7.5 and 15.7.7 update, particularly.
I'm running Mini with M4 Pro and 48 GB RAM. I did have 1200 tabs open (I since closed them all and cleared all the caches, etc.). It loads in under a second, and is very responsive. I don't have any extensions loaded.
