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.
@eurozerozero @nicolas17 Fingers crossed for an OS-level fix in 15.7.1…
@willcroft @nicolas17 I’ve already updated to macOS 15.7.1 and the issue persists, unfortunately.
The trouble is getting anyone to look at the bug report.
It’s been literally years since I received even a generic reply to a Feedback report (even for bugs I can 100% reliably reproduce) so I don’t hold much hope of a quick fix, especially since their focus is on macOS 26. It might never get fixed.
@eurozerozero @nicolas17 Sad to hear this! Upgraded, but haven't seen the bug yet. I saw a fix for autofill in macOS 15.7.1 but clearly not related to the URL bar/history subprocess issues we've seen. Holding out hope for Safari 26.0.2 instead, then 🙃
Definitely aware of the black hole that is Radar!
@willcroft @nicolas17 Yeah, I saw that as well and was going to ask Ricky if it could be at all related, since the symptom sounds similar. I’ll be crossing my fingers too!
