My 2024 MacBook Pro is crawling!

your files appear to be in a very precarious state.

You have a Seagate Disk driver loaded.

Best Practice on a Mac is that every drive intended for use only on a Mac should have been Erased at the Physical Device level with Disk Utility, so that Disk Utility Drivers "own" the drive, and every type of MacOS Utilities, including Recovery, can always access the drive.

When you keep the drive-maker's Utilities, you may only be able to access the drive with Full MacOS AND the drive-makers Extensions/Utilities loaded. This is not possible when you may need it most, such as after a failure.

In addition in your case, BOTH the Seagate driver and Disk Utility have encountered a drive situation or conflict so unusual, each experienced a kernel panic:

The kernel is the core of the operating system.

When the kernel detects a condition that is really bad – say, a condition that the developers think should never happen – it may intentionally crash your Mac. This is called a kernel panic. The idea is that if things are really messed up, it is better to crash (calling attention to the fact that there is a problem) than to try to carry on, and perhaps compound the problem.

That report contains details for one kernel panic.

I don't have all of the tools or source code to decode this, but it sounds like some piece of code concerned with handling a Seagate drive was waiting for an I/O operation to complete, and timed out after roughly 20.5 seconds passed with no progress. (One would expect a hard drive to respond in a lot less than 20.5 seconds.)

when you get your drive situation under control,

Next on the list of resource hogs is Non-native File Sync-ers. Dropbox, BackBlaze, OneDrive, Carbonate, or Google drive and others are in this category. Since they were ported from that other OS environment, they IGNORE the Mac File System Event Store (that could tell them EXACTLY what folders have changed recently).

Instead, they do a a Brute-force read of all your files, and all the files stored on their drive on the Internet. This punishes the ability to get any data (including speed test data) through their enormous and frivolous file reading and re-reading.

They are also 'on the phone' checking and re-checking the synced file stored on the internet. Between constant scanning and constant Internet access, this uses a LOT of resources -- far more than Apple-native File-Syncers like iCloud. Running File-Syncers when not actually needed still consumes a lot of computer resources.

You should NOT be launching these at Startup, but instead launch only when needed, and quit when Sync-ing is complete.

Settings > General > Login Items and Extensions ...

remove all items shown here.

When actually needed, their app will add those background items.

A modern Apple Silicon computer should be 3 times faster than that.

That's curious. That should say "MacBook Pro (16-inch, 2024)". Looks like a bug in EtreCheck.

disk6 - LaCie d2 Professional 10.00 TB External USB Up to 480 Mb/s

That drive is connected to a USB 2.0 bus. That could explain the performance problems.

/Library/Extensions [Not Loaded] SoundflowerSigned.kext - com.Cycling74.driver.Soundflower (Corel Inc., 1.6.7 - SDK 10.7)

This isn't a problem, as it's an older kernel extension that isn't being loaded. However, this indicates you've done a few migrations. Might be time for a rebuild to clean out the old stuff.

3rd Party System settings: Toolkit (Seagate Technologies LLC - installed 2025-10-15)

This seems to be the cause of the kernel panic. 3rd party preference panes are old and rare. I'm not sure where they really live on disk anymore.

You can look this up yourself in Terminal using:

/usr/sbin/system_profiler SPPrefPaneDataType

That should give you the information you need. This is what EtreCheck uses. If you had the Power User package it would give you a button to identify the file. At least I think it would. 3rd party preference panes are rare. Haven't seen one in a long time. And I just shipped a buggy EtreCheck anyway. What do I know?

Performance: Nominal I/O usage: 48.40 MB/s Top Processes Snapshot by CPU: Process (count) CPU (Source - Location) backupd 71.32 % (Apple)

It looks like you may be running a backup. You also recently restarted your computer. It's better to run EtreCheck after the computer has been running for a while.

"My 2024 MacBook Pro is crawling!: My 2024 MacBook Pro has been running excruciatingly slowly lately. Even the wifi has been really slow (even though I know that is is not! Below is the report that I got from EtreCheckPro. It says that, among other things, I'm having Kernel Panics. What does that mean? Thanks!"

Lagging Mac:

A. Resources Swallowed Up:

Excessive RAM is used, and 80% of your hard drive is used. Look in Activity Monitor, and see what is eating up your RAM. Bitdefender is one. Go Here: Activity Monitor User Guide for Mac - Apple Support

B. Uninstall Bitdefender:

Bitdefender is installed, and is taking up almost 2 GBs of your RAM --keep Security Software off of your Mac, sit gets in the way, and this is a put example of how and why. Go Here: How to Uninstall Bitdefender Antivirus for Mac - Bitdefender

C. Remove Login Items:

Boot in Safe Mode. While in Safe Mode, remove all of your Login Items, and then restart the Mac.  Go Here: Change Users & Groups Login Items Preferences on Mac - Apple Support

D. Clear System Data:

System Data includes caches, all of which are created as you go about using your Mac, so that items open with ease. So, clear it, by viewing in Disk Utility and see if it is taking up an excessive amount of storage. It is unnecessary to have, and you'll get lets of extra space, and a faster Mac, as a result. Use my User Tip: How to Use Finder to Clear “System Data" on a Mac - User Tip

Start by uninstalling bitdefender and any VPN you have installed.

In addition to @BobTheFisherman's excellent suggestion, you may want to review the following article:

Hello:

I just deleted BitDefender and Mullvad VPN. How do I go about removing the Seagate Driver? I used "Find Any File" and there are a number of items listed there, but I didn't want to delete anything if I didn't know what it was.

Thanks again!

you have your d2 drive plugged in to a slower port, and a faster port show as "open"

USB:

USB 3.1 Bus

USB 2.0 BILLBOARD

Exactly how that maps to the physical ports is unknown, but If USB-A, would try the port with the orange insert on the front for the drive alone.

I also have LaCie RAID manager installed. Should I delete that as well?

Thanks!

That’s a lot of network connections…

That USB 2.0 480 Mbps connection is almost certainly a charging cable, not an appropriately-rated data cable.

I have to split a bunch of peripherals for my laptop. Is there a better way to attach everything that I need without my "TobenONE 16-in-2 MacBook Docking Station Dual 4K@60Hz, 7 USB, 2 HDMI"?
