To avoid the question / answer and question answer scenario

Download the Application Etrecheck ( External Link ) directly from the Developer.

The Application is Not a " Silver Bullet " but only a tool to examine the Hardware / Software used on this computer 

This is a Diagnostic Tool that makes no changes to the computer.

It makes a coherent and readable inventory of both the Hardware and Software used on the computer 

The application is free or paid for added features.

Lastly - should you decide to use and post the Report now or at a later time, we are willing to have a very close look and offer some insights 

The Seagate software never installed any drivers (or at least did not activate the drivers) since I don't see anything related to Seagate in the EtreCheck report. I also don't see any of the typical software issues although you do have some items installed which I am unfamiliar since I am not a macOS software expert. You can try uninstalling the Seagate software to see if that resolves the problem. Use the Seagate uninstaller or follow Seagate's instructions for uninstalling the software. I guess you could also check the Privacy & Security System Settings to see if you may need to approve the drivers to be loaded. You need to do this when first installing drivers and sometimes after a macOS update as well (even some Apple drivers may need approval after an OS update patch....I've seen this occur a few times with recent versions of macOS Ventura & Sonoma).

I am most concerned about all those "ProxiedDevice-Bridge" panic listed (over 200). Those errors are usually associated with a hardware issue with the Logic Board since they are referencing the T2 security chip. You can attempt to perform a DFU firmware Revive which will reset the T2 security chip & system firmware. If you continue to receive more of those "ProxiedDevice-Bridge" panics, then most likely the Logic Board is bad although you could try a clean install of macOS (I would perform the DFU firmware Restore followed by the reinstallation of macOS).

How to revive or restore Mac firmware - Apple Support

Personally I am not sure it is worth repairing any of these Apple USB-C Intel Macs since the 2018-2020 Intel Macs tend to have a much higher rate of Logic Board failures than older models due to the T2 security chip. The price for a repair I believe is much better put towards a new computer since a repair will be expensive anyway.

Plus many times the Apple Diagnostics (even the Apple service diagnostics) may not report any problems even when a hardware issue exists. This makes it difficult to get Apple to consider a repair unless you have the issue after a clean install of macOS (fully erase the physical internal SSD followed by reinstalling macOS, but not installing any third party software, nor restoring from a backup, nor signing into your AppleID/iCloud).

FYI, in the future please make sure your pictures are in the correct orientation when posting here since I usually avoid analyzing pictures that are sideways or upside down. You can easily rotate the pictures on an iPhone/iPad by using the instructions in this Apple article (I assume Android devices will a similar ability). You can also delete a picture before clicking the "Post" button & attaching a properly oriented picture.

Thanks, I have been a way down that road. I have disconnected all drives, done a Safe Mode, been through the Applicartions and Library and User Library and removed all old Application Support, Preferences, Printers, Extensions I am not using. No change to the boot time but at least now the bluetooth is working on startup. It is the time before I login that is the issue. Note that VMware, Drobo and Apple Aperture are programmes that I use all the time and that is why I am still on Monterey. Etrecheck is attached as Additional text.

<Etrecheck.log>

Having looked at the report in detail, coupled with " Thanks, I have been a way down that road "

This is one heavily configured machine with at least two external drives attached, as per the report

Can only image what these drive maybe used for

Then, can basically already know what the answer /suggestion might be - right .

The machine can support >>

Two Thunderbolt 3 (USB-C) ports and invest in two external drives that support thunderbolt 3

Wow! Find Any File is my new best friend. Although Etrecheck said "seagate" was all gone, Find Any File found eleven of them in places I have never heard of. I removed 7 and that took a minute off the boot time. The repeating log messages are still there though.

However there are 4 I can't remove. I tried CMD-I and increasing the permissions but it won't let me remove them. Two of the 4 are inside two others but I need to remove

MacintoshHD/Library/StagedExtensions/Library/Extensions/SeagateDiskService.kext and

MacintoshHD/private/var/db/KernelExtensionManagement/AuxKC/CurrentAuxKC/StashedExtensions/ (long name) /SeagateDiskService.kext

How can I do this please?

I’m sorry that EtreCheck wasn’t able to help. EtreCheck only lists components that are loaded by the system or potentially loadable. It looks like this extension was in some kind of unloadable zombie state. I’ve never seen this before. EtreCheck doesn’t normally go looking directly in those folders. It asks the system for a list of extensions. Since your extension never actually gets loaded, it never gets listed.

My recommendation is to erase the hard drive and reinstall the operating system.

Wonderful App, I hope Apple doesn't buy it & ruin it.

Try disabling sip...

Get Find Any File...

Hold Option or alt key when selecting Find to Find All.

Find All for Name>Contains>Seagate

Restart after deleting any you find.

Will get a good look at the report early Friday AM and get back to you

Why do you have Seagate drivers installed?
