Ok! I was wondering about that too. My laptop can't upgrade to Sonoma, but on Ventura, we have been getting updates to Safari. The most notable change was the addition of Profiles. Ever since that update, Safari's performance has been very uneven. Sometimes it runs normal, and sometimes it would just hang on particular webpages. I was thinking it may have something to do with iCloud private relay, which I do use, but maybe that's not it.

Because of these performance issues, I no longer use Safari as my main browser for work, which is sad. I much prefer it for a number of reasons including privacy and that it crosses all my personal devices.

Sounds like Private Relay. I have it turned off on my home network as I’ve noticed issues similar to your’s with it enabled.

How much RAM do you have, and on which Mac? Safari/Sonoma on my M2 MBP with lots of RAM has been totally stable. I have left multiple Safari (currently 17.1) pages with scores of a wide variety of tabs open for weeks w/o a hiccup under 96 GB RAM. Activity monitor shows my overall use (includes multiple other apps, and images work) typically accessing ~50 GB RAM.

We have all along expected RAM demands to increase over time. <as always>

Edit: Always in the past I rebooted every day or two for stability, just out of principle. With the M2, Sonoma and 96 GB RAM I have evolved into rebooting maybe once a month, just out of principle. Sonoma has been a very solid OS in my experience, and I have experienced every Mac OS - - except the ones I skipped.

Open apps: Filemaker, Safari, Mail, Pages, Affinity, Photos. Displayed on three 4K displays plus the MBP display.
I'm on a 2019 iMac, Memory: 32 GB 2667 MHz DDR4. Problem apps have been Adobe Creative Suite and most of Office.
 
ExFAT drives don't mount for me when I boot up or reboot, they are not ejected properly by the OS.
I have to wait a long time until they show up.


I updated to sonoma 14.1 (clean install), and it seems that my external hard drive that I always have plugged in takes ages to mount, this only happens when the mac reboots or shut down, I know this is normal behavior when you unplug a hard drive without ejecting correctly, but now is happening every time I boot or restart the Mac.

did not happen on Ventura.
UPDATE: just tested it. STILL NOT FIXED. Unbelievable.

I finally leapt to Sonoma 14.1.1 couple days ago from Ventura 13.5.2

been smooth so far on 15" M2 Air.


Will wait for a little feedback on this one, then maybe go for it. 14.1.1 is like 3 or so weeks old iirc.

What problems were you seeing with exFAT drives? I haven't noticed any issues on my end, but I'd be curious to know what issues people were having.

Lots of people, including me are having issues with Sonoma and exFAT drives.

Specifically, Not recognizing the exFAT formatted external, or 'missing' files/folders with Sonoma.

Plug into a Windows PC and everything is fine. Plug into a Ventura MacBook and all is fine. Plug into a Sonoma and oops, what's that?
 
Completely wiped my Time Machine backups… all gone. But disc space is still used…
Get Paragon HFS or APFS for Windows and mount it on a windows device.

Or if it is an exFAT formatted time machine you can use a Ventura or older version and restore clean, then format as APFS and time machine back to the drive and then use it in Sonora.

I feel like Apple unofficially said, hmmm exFAT isn't a good drive choice, so they are forcing us to go to APFS, but rather than 'warn' us that Sonoma won't work, they force us to 'submit' (or else, they f'd up big time and haven't/don't want to fix it)

I had to format two very large RAID boxes. Didn't lose anything as they basically were the same data so I could run a DirEqual, sync them then format one as APFS, then copy the other to the newly formatted APFS, run DirEqual again, then format the exFAT to APFS and copy the newly formatted/Copied APFS drive to the newer formatted APFS drive.


Big hassle, but I didn't lose anything so there's that.

It is APFS, time Machine is formatting it automatically to APFS.
 
Sonoma has by far been the most unstable OS I've had in years. Apps will just constantly freeze when I go up to the menu bar to select on something. Really ridiculous, I hope this update fixes the issue.
I jumped over to Sonoma on version 14.1 and have had zero stability issues. I'm quite impressed really.

Two issues I've noticed is that I sometimes get the spinning beachball for a few seconds when unlocking the computer if I have a lot of stuff running and in System Settings it sometimes happen that clicking the ”Network” section in the left column doesn't actually load it and a re-launch of System Settings is required. This is a remnant from Ventura, but it seems to happen a little less on Sonoma at least.

Apparently it isn't all exFAT drives. I just got one usb thumb drive to show up.

But another one, a different brand, won't even show up in Disk Util. And that one works fine in Windows.

Got it. Thanks for that. It hasn't happened to me, but my cousin was talking about one of her drives didn't work on her Mac. I haven't peeked into it, but now I know to check and see if it might be an exFAT drive.

And here I thought ex-fat was the new universal format 🤔😳😡

Oh, Crapple!

Don’t get me started on spinning, platters, and which format they should be in to play nice with everybody… or conflicting information on which format it should be if you are solely in the Apple ecosystem!

Interesting. Adobe has always craved RAM and Safari is a hog, but with 32 GB I would think you would be OK. How full is the internal SSD?

Give us a break. Your claim is made by someone with every single macOS release since time began. It's always the worst ever for somebody.

Does this fix the Quicktime controls being unresponsive 90% of the time? Or will this make my M1 MBP not crash when connected to a Studio Display and playing a video in Quicktime?
