Will CroftIs anyone else experiencing insanely slow address bar autocomplete behaviour after updating to Safari 26 on macOS 15.7 Sequoia (ie not Tahoe)? Infuriating!
eurozerozero@willcroft Yes!
@eurozerozero Glad I'm not alone—maddening!
@willcroft Yeah. And after a while, even just clicking on the address bar to make it active becomes sluggish for me.
@eurozerozero Same, everything just slows to a crawl and eventually letter-by-letter typing starts to beachball. Will report back if I find a culprit/fix. Hoping for a speedy 26.0.2. Perhaps @jensimmons would know if this is a known bug or worth reporting?
@willcroft @jensimmons I ended up submitting this as FB20414621 because it seems to be getting worse. Today Safari 26 even crashed after beachballing for a long time while trying to type in the address bar.
The bad performance seems to get worse in relation to how long Safari has been open or how much browsing has been done, so initially everything seems fine, but after a few hours it sometimes takes seconds to respond (on an M4 Pro!).
@willcroft @jensimmons @nicolas17 I’ve added reproduction steps to FB20414621.
I can 100% reliably cause Safari 26.0.1 on macOS 15.7 to slow down and eventually close by repeatedly typing and backspacing in the address bar.
Even once I stop typing and it eventually goes back to 0% CPU, the whole browser is then sluggish when doing things like clicking into the address bar or maximising the window. Continuing to type/backspace causes it to lock up and close.
@eurozerozero @jensimmons @nicolas17 Thanks for the diagnosis—reproduced! 🙏🏻 For me, it's specifically the com.apple.Safari.History process though, which makes sense if it's trying to match results. I have history retention set to 1 year.
Jen Simmons@jensimmons @willcroft @nicolas17 Hi Jen, is it possible to get an update on how the investigation of this is progressing? It’s still in Safari 26.1 on macOS 15.7.2 and it is hugely impactful in day-to-day use.
I can easily reproduce this just by using the address bar in normal use, or instantly by repeatedly typing and backspacing in it. Lots of other people are reporting the issue in the wild.
Screen recording attached on Safari 26.1 showing runaway memory use (and it was then terminated).
@eurozerozero @willcroft @nicolas17 Try on Safari 26.2 beta: https://developer.apple.com/safari/resources/
@jensimmons The release notes are there, but there’s no download available for Safari 26.2 beta (it’s still showing the links to 26.1 beta).
Nicolás Alvarez@jensimmons @eurozerozero It's *finally* released.
@nicolas17 @jensimmons Thanks for letting me know – I checked it a day or so ago and it wasn’t there. I’ll give it a go!
@nicolas17 @jensimmons Jen, thanks for following this up. After using 26.2 beta 1 for an afternoon, I haven’t experienced the problem, so I think it might be fixed!
Please also pass on my thanks to those on the team.
@jensimmons @eurozerozero wonderful news, thank you Jen and team for the fix!
