macOS 14.3 - Bug fixes, changes, and more

[gank41]

I'm running a 14" M1 Pro and YouTube all of a sudden seems to be using 100% CPU in Safari. Youtube is so laggy and slow (as it's using the entire CPU). This has only happened since updating to 14.3 -- anyone else experiencing this? Everything else runs fine -- in Safari at least.

Yes, it's my understanding that it has to do with YouTube's check on whether Safari (Specifically) is using any extensions that would block ads and things. It might be further down now in the forums, maybe even some months back now. But there was one about Safari Extensions and YouTube not working anymore.

In my case, "sometimes" I'm able to play videos on YouTube directly, other times I get a message about ad blockers not being allowed, even when I have everything for YouTube disabled. But then I'm able to just watch that same video as an embedded video in Messages or something.

Interesting. I have an Adblocker installed and like you it was 50/50 as I'd load the video in Safari and airplay to my appletv to watch whatever ad-less but now it's just kind of a mess.

I think it's stupid as well. Very strange, but at least you can do it. It even shows you which mailbox you are searching lol. Very confusing. Happy days

This isn't anything new with 14.3. It's been the new default with Sonoma from the get go. It's taken a little getting used to, but I'm fine with it now.

Overall, the OS has been rock solid for me.

After playing around with resolution changes, turning off transparency, motion, then running safe mode. Magic Trackpad has stabilized somewhat. The delay/stuttering/sudden jump has minimized somewhat. Sometimes it doesn't happen for quite a while but it still does during the day. Funny that this was happening in Ventura when the iMac M3 arrived and I was setting it up. I just hope its not one of those obscure random issue with a sourced BT component that's causing this. Anyway its much better but nothing like wired connection that completely removes that behavior.

I have been using FireFox with the Ad BlockPlus extension flawlessly in Sonoma.

The same for me in Chrome but also I use Safari to airplay to my appletv if I want to sit down and watch something on the big tv.

Weird. Sometimes the Dock doesn't recognize the mouse over it. I have it magnify when the cursor is over it, but nothing happens, then suddenly it does it if I move the cursor a bit. It's happened twice now...

I just experienced something I've never seen before and I'm hoping someone here can help me understand it. I have a M3 (non-Pro) 16Gb that's a few weeks old. It's been fine, but I'm doing just basic browsing today, and office tasks, and it started to slow down massively. I always use Firefox and rarely have problems. Can someone explain why all of a sudden (see screenshots) Firefox is taking up so much memory and swap? Closing Firefox fixed it but I've never seen anything like this. Thanks.

After messing with all this nonsense all day, I’m kinda thinking it’s 14.3 Sonoma. My Mac Studio (albeit 2x as much memory as the M3 MBP) is on 14.2.1 Sonoma and doesn’t have any of this problem. Any ideas?

Can you check if Chrome has a similar problem? I have no this kind of issue using Chrome.

I tried Brave and never had a problem. I just don't like the Chromium-based browsers.

Yeah.....Safari and Safari Technology both display or lack there of a black page when I go to https://www.macintouch.com/, every other browser I have works flawlessly on his site, I've disabled every extension (only a half dozen) with the same results, and this is on a supported iMac, ( running 14.4 beta (23E5191e) the unsupported (14.4) iMac displays it fine. I could just trash all of the pref's and see if that works. It's the only site that does this. Ever since upgrading from Ventura Ive had this issue. It doesn't make any difference what version of Sonoma, blank page. Aside from that it's super stable, the only app that's a little wonky is Pelican, I can't delete any entries, great app btw. That's my rant.
