Problems after Sonoma 14.6.1

+1 from me. Updated my 2019 3.6ghz i9 64gig system to 14.6.1 a few days ago, performance has become absolute garbage with frequent hangs from any app, whether using disk or not. Full reboot login takes about ten minutes. Similar to OP, until I found this thread, I'd heard the normal grinding away of Time Machine to my 9tb spinning disk target and assumed things were fine, only to realize I've also had no successful backup since 14.6.1 went on.

After the most recent reboot, apfsd was consuming 100% cpu for several hours, that's subsided and now it's on to mdsync. I do have an external (Thunderbolt 2 to USB-C adapter) raid array, 9tb with 5tb in use, which presents as a single drive to the Mac, and the internal fusion drive. Perhaps 14.6+ has:

• changed something related to APFS, its journals, etc. that must complete before Time Machine can begin functioning again.
• whatever that is also dramatically impacts disk performance until it's done.
• maybe that process can take several days to a week or more? I don't feel like I have an excessive amount of data or files; my inode count on the external volume is ~500k files, although on the internal /System/Volumes/Data it's a ridiculous 42M, which I hope relates to snapshots because I don't even use the internal drive for anything but apps and the files they keep in my home directory for preferences, etc.

Either way, the computer is barely usable right now. I updated my wife's computer at the same time, it seemed fine afterward, but today, same day as my problems got dramatically worse, it lost the ability to obtain a DHCP address even though tcpdump showed packets coming in on the network adapter that was supposedly not working. I added a USB dongle ethernet device and it magically fixes the issue.

Just some really questionable stuff going on with this release. The fact that we both had an issue on the same day makes me wonder if Apple pushed out one of those behind the scenes zero day patches that MacOS will grab even if not set to auto update.

Is there any official report on 14.6.1 troubles? System crashed and recovered 2 days after install. I recovered again bc intelligentroutingd was running 120%+ CPU. That recovery did the same thing. I recovered back to 14.5 and life was great. But at some point, 14.6.1 was updated and intelligentroutingd is taking over, can not stay connected to apple account to messages and phone calls, downloads are all corrupted.

Went back to a FRESH no recovery and again, this intelligentroutingd takes control. I can not find anything about it but beta Xcode uses it. I never had beta, but removed it still there. Didnt install Xcode, 14.6.1 boom its back like the Terminator.

Is this only effecting the MBP Intel systems? It would be a shame to be forced to M# processor. I wouldnt be able to create VMware servers and send them to the production environment, being they are intel processor servers. I would be forced back to Windows or Linux.

MacBook Air 2020 Intel, the laptop got same issue with very slow login after being shut down.

Other issues just appeared on my Mac after updating this OS:

1. Don't plug in to charge but the laptop shows plug symbol. Charging cables work fine, already checked with iPad. Need to reboot to clear that plug icon but happens again whenever I plug in and still shows plug symbol when I already plug it off.
2. I shut down my Mac or restarted it normally not because of being frozen but whenever it's on after being shut down or restarted it shows the usual error message "your laptop was shut down due to a problem..."

Photo below shows how weird it is when it shows plug symbol while I don't plug it in at all!

Yes, I had to reinstall paragon NTFS in order to run backups on my type of external HDD. It was unusual. But after research, I wasn't the only one having to do that and everything seems so to be running fine since.

Same issue here but Apple support not acknowledging the issue. I have done a clean OS install, ran Time Machine to reinstate and it worked fine... for ONE day ! Cannot use the MacBook as every thing you try to open crashes Finder, Cannot move files either.

Need URGENT fix!

After upgrading to 14.6.1, there was a problem with the proxy. After turning on my mbp 16 m3 max, the networkworks fine, but if it falls a sleep, then in many applications the network falls off and writes the error ERR_PROXY_CONNECTION_FAILED, but it is worth connecting the OUTLINE proxy and every thing works fine. After disabling the proxy, nothing works again. Yesterday everything was fine, because I constantly turn on/off the proxy. This is a big problem, many sites do not work with proxies and it is extremely time-consuming to reboot the system.

Really well earned

Could not wait for the Official Announcement

Re- reading OP original " After the reboot it took a LONG time to mount my backup partition. Several minutes after the other partition on that drive. Time Machine now works. "

This spells potential overall issues for TM Backups - Partitioned TM Backup drive - IMHO

I have a MacBook Pro 2018 intel. After updating to Sonoma 14.6.1 I can no longer record or bounce files in pro tools and I keep getting disk permissions error 69841 when I try to repair or reset disk utility permissions. Right now it says my Mac HD is read only and I do not have permission to change it.

My problem is while editing in FinalCutPro 10.8.1 for playback on my 2021 MacBook Pro in a live performance tomorrow, suddenly, "Music" starts randomly playing a track. This would be a disaster if I'm playing live out of FCP in a performance. I've created an mp3 track of 4 hours of silence and imported it into Music so that's what it will play if it misbehaves "on the night". This occurred for the first time within an hour of downloading Sonoma 14.6.1

As time goes on, my enthusiasm for Apple as a company continues to nose-dive. Updates cannot be trusted. New machines don't live up to their sales pitch. Whatever happened to Apple? Are they trying to get rid of us?

I just reinstall my Mac. Everything was OK, but only thing you can’t use internet at all in any application.

I tried many things like disable vpn, forgot that wi-fi and I try it connect it with Ethernet cable and also didn’t work.

Now I am trying to completely reinstall and I hope it’ll work fine.

I use this antivirus, but the performance issue was present even when working in safe mode, where this antivirus is not active.

It seems to me that this issue with CrowdStrike Falcon was only present on Windows computers

Still disappointed with sonoma. Taking sreenshots does not work after long period of screensaver. Lot of hangs with finder handling large usb sticks. unmounting usb sticks often takes more than minutes or hangs.

After update, News and Stocks will no longer work via the MullvadVPN (version 2024.4) on my M3 MacBook Air. They both work if the VPN is turned off. Super bummer. I use open access points frequently, and my ISP openly exploits any data it can read, including IP addresses (it’s right there in their Ts&Cs).

Mail, Calendar, and Maps are fine.

I tried deleting and reinstalling Mullvad. No effect. I would delete and reinstall News, but Apple no longer allows that via the Finder (haven’t tried Terminal yet).

Anyone else with this problem? Are other VPNs working?

Definitely won’t update our other Macs until there is a resolution…also afraid to update iOS and iPadOS at this point...

Similar issues here on M3 Max MBP - this is the first time I've ever installed a new Mac OS update and things have gone horribly wrong. I can't play videos (the window just crashes), safari seems to be really struggling, all my apps seems slower. What the **** is going on?

Same here. MBP 2020 M1

• Safari not working properly, no downloads, no export pdf
• Finder break downs
• not opening pdfs
• Microsoft 365 break downs

It's a mess, can't work like that.

Please fix it asap, Apple!
