Experiencing slow performance on my iMac post Sonoma 14.4.1 update

Just an update ... after trying everything, I ended up buying a 5TB backup drive, taking a backup, wiping the drive, and fresh installing Sonoma 14.4.1. There must have been something in cache somewhere causing havoc. Anyways, fresh install, and restore of files, and all is well. I love Mac but in times of trouble one is truly alone on that bridge ...

Part 1 of 2

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster. 

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a percentage on each sale. 

What the Application may do to the computer is up to the User to check this out before purchase

Any of the below should be removed as per Developers Instructions 

Disk Cleaner 

This will include CleanMyMac , aka “ BrickMyMac “

Part 2 of 2

Specific to CleanMyMac aka “ BrickMyMac “

To put the CleanMyMac in context and the damages it may have or has already done.

This application can or will Muck Up your User Account ( Home Folder ) of this machine.

It does not touch the Operating System itself unless you consider your User Account ( Home Folder ) as part of the Operating System

Then in that specific context - it has Mucked Up the Operating  System 

The steps in #1 below is predicated on the Offending  Application has been Removed as per the Developers Specific Instruction 

# 1 Some Contributors suggest restarting in Recovery Mode and choosing to Reinstall the Operating System over the existing installation. 

This may or may not replace elements of the Entire Operating System including the Home Folder ( User Account )  and replace any corrupted or removed elements and make things right.

#2 - Then there are Other Contributors ( like myself ) would suggest  from this link Use Disk Utility to erase a Mac with Apple silicon.

For Intel computer >> Use Disk Utility to erase an Intel-based Mac followed by How to reinstall macOS

Thereafter to start from scratch and install all Required Application directly from the Apple Apps Store or Directly from the Developer.

If going this route - I suggest Not using Startup Assist to migrate things back as this will probably Re-Introduce the existing  issue that existed when the TM Backup was made 

William, I am having the same issues. I've been working on this since Sonoma came out. I have sent numerous FeedBack Reports to Apple.

I ran EtreCheck as tbirdvet suggested and in the first go around it reported unusually slow performance and that it is not normal. I am running it again with Full Disk Access and will post the results when done.

No performance issue prior calling for an update at this time. So updating with all of the jumping through hoops and safe made to get a problem update seems like a useless endeavor.

The use may consider this other question for a response to the above

MacOS 14.4.1 Update MAJOR issues - Can up… - Apple Community

My 27" iMac runs fine with 14.4.1. First restart in safe mode then restart normally and see if any change. If not run the free app EtreCheck and post here for review. I do not recommend CleanMYMac as it can cause issues by itself.

thank you everyone who replied to my post. I obviously needed more coffee, or should have reviewed my post before submitting. I stated I have 3GB of hard drive free. LOL. I meant I have 3TB of hard drive free. Nit sure I can say the same for my brain, at least at that early hour. Anyway, another day of poor productivity. It actually hung up trying to move files to trash. I had to hold the power button down to get a reboot. Will work toward going back to Ventura this weekend.

Hello all,

Before doing anything drastic, check to see if your MACK has a fusion drive. These were used circa 2019, 2020.

I was experiencing the same issues that all of you have with the slowness of Sonoma. I did a lot of unnecessary installs and reinstall, etc. None of those helped at all. I finally came upon was a split fusion in my machine. If your machine has a fusion drive, let me know and I will find the articles to help fix the fusion.

Repairing fusion my machine was like lightning again Sonoma.

Take a backup, erase your disk, install Ventura 13.6.6. It took me 2 weeks, lots of wasted time, and missed work to figure it out.

I am having crashes on Sonoma 14.4.1 macOS watchdog kernel panics every 20 mins to 1 hour. On April 2 I updated Adobe Acrobat, I then updated my macbook pro (below) to 14.4.1 on Tuesday. I have had continuous kernel panics all week despite everything I've done to debug this until today. Looking through the update logs, I noticed on Apr 2 I installed Adobe Acrobat update. That's when all of this started happening. Looking through sys, panic, and crash logs, I noticed a couple things and turned off certain services to see if I could figure out which service was causing the kernel_panic. I saw references to panic for DYLD and I also found BAD MAGIC! errors in the Backtrace. Poking around I found more reference to DYL..D in the EtreCheckPro as part of creative services in the log.

So I stopped these services:

Adobe Content Synchronizer Finder Extension (491)

Creative Cloud Interprocess Service (647)

Creative Cloud Libraries Synchronizer (777)

I have plugged back in all my devices, displays, screens, etc. I haven't had a single kernel panic for 2 hours now. I am not sure what this means other than maybe the Adobe Acro update, and the latest Creative Cloud updates have issues with 14.4.1.

This is an Apple issue. My Mac has plenty of memory and is running fine on OS 14.4. The update to 14.4.1 hangs at 30mins forever.

ONLY 3GB free?!!!!

That is KILLING your mac.

Any system drive needs to have at least 15-20% free just for OS to work correctly.

I spoke too soon. Not long after I wrote that, I was crashing on watchdogd once again in the BridgeOS. I had to go back to BigSur, and then update to Ventura. I will stay here until Sonoma is fixed or after, maybe never.

I think i've figured out the issue, in reality it wasn't sonoma 14.4.1, it was more so my storage. i was nearing around 400gb/512 which was slowing down my computer, so you should probably clear your storage if it's near full, and that will speed up your computer
