Mac freezes everytime I connect to internet whether it is via wi-fi or Ethernet

Ok, thanks for the additional information and not to worry, I'm not here for the points ... just trying to help others where i can.

Since you are having this issue regardless if you use cellular or DSL Internet, is certainly perplexing. Have you tried simply creating a new user account on your Mac. Log out of your current account, and then, log in with this new account to see if it makes any difference? If it does, then there is something wonky with your current account.

... but, again, just to be sure I understand. Do you actually have two separate Internet service providers? T-Mobile cellular & Century Link DSL Broadband? ... and both are affecting your Mac exactly the same?

Lastly, any chance you can take your Mac to a friend's or relative's home and try accessing their Internet service? As you can imagine, if it works, then that would narrow it down to your home's network. Otherwise, it's pointing at your Mac as the culprit.

Per chance do you have any peripherals, other than a keyboard/mouse, connected to your iMac? If so, running in Safe Mode should have eliminated enabling any of their drivers, but one additional step would be to temporarily remove them to see if the freezing stops.

If you don't have any additional peripherals, then I would look into the diagnostics logs to see if your Mac has had any kernel panics or app crashes. Those too should have been caught in the EtreCheck report under the Diagnostics Information section ... but possibly may not have.

Alternately, there are a number of methods to directly access these logs. One of them is via the Console app, that is located in the /Applications/Utilities folder. For macOS Monterey: Console > Reports > Diagnostics Reports

Sorry, but panic reports are hard enough to read, but having a screen shot of one, makes it a bit more difficult. I only need to see the first third of the report. Just copy & paste it from the Console to the Additional Text tool ... like you did for the EtreCheck Report.

I'm specifically looking for the "Panic Caller" and the loaded kexts listings to see what the potential cause of the panics is. Since your Mac only experienced a single one, chances are this could be either app-related, or as John Galt has indicated, a potential hardware issue.

You didn't mention anything about your system drive. I see that it is a Fusion-type drive. Have you tried running the First Aid option under the Disk Utility yet? ... or better still, used an app, like DriveDx to see its overall health?

It sounds like you are having a problem with your Mac freezing whenever you connect to the internet, whether via Wi-Fi or Ethernet. This can be a frustrating issue to deal with, but there are several steps you can take to troubleshoot and resolve the problem.

1. Check for updates: Make sure that you are running the latest version of macOS and that all of your software is up to date. You can check for updates by going to the "App Store" app and clicking on the "Updates" tab.
2. Restart your router: If you are experiencing problems with your Wi-Fi connection, try restarting your router. Unplug the router, wait a few seconds, then plug it back in and see if the problem persists.
3. Check your cables: Make sure that all of your Ethernet cables are securely plugged in and not damaged. If you are using a Wi-Fi connection, try moving your Mac closer to the router to see if the connection improves.
4. Reset the SMC: Resetting the System Management Controller (SMC) can sometimes resolve issues with freezing and other problems. To reset the SMC on your Mac, follow these steps:

• Shut down your Mac.
• Unplug the power cord from your Mac.
• Wait 15 seconds.
• Plug the power cord back in.
• Wait 5 seconds, then press the power button to turn your Mac back on.

1. Repair disk permissions: Disk permissions are a set of rules that dictate which users and processes can access certain files on your Mac. If these permissions are damaged, it can cause problems with your system. To repair disk permissions, follow these steps:

• Open "Disk Utility" from the "Utilities" folder.
• Select your hard drive from the list on the left.
• Click the "First Aid" tab.
• Click the "Repair Disk Permissions" button.

1. Reset your Mac's NVRAM: Non-Volatile Random-Access Memory (NVRAM) stores certain settings and information that your Mac needs to access quickly. Resetting NVRAM can sometimes help resolve issues with freezing. To reset NVRAM on your Mac, follow these steps:

• Shut down your Mac.
• Press the power button to turn it back on.
• As soon as you hear the startup sound, press and hold the "Option," "Command," "P," and "R" keys together.
• Keep holding the keys until you hear the startup sound a second time.

1. Check for hardware issues: If none of the above steps have helped, it's possible that you may have a hardware problem, such as a faulty RAM module or a failing hard drive. You can try running a hardware diagnostic to check for any issues. You can also try booting your Mac in "Safe Mode" to see if the problem persists. If it does, it's likely that you have a hardware problem.

I hope these steps are helpful in troubleshooting and resolving the freezing issue you are experiencing with your Mac. If you continue to have problems, it may be best to contact Apple support for further assistance.

There also may be a possibility that your network connection may be suspect. With that, it's typically easier troubleshooting a wired connection first, and then, on to wireless should it warrant it.

Since you are only seeing this "slow-down" when connecting via either method, we may want to tackle this first before digging too deeply into panic/crash reports.

... but before taking this path, and just to make sure I understand. This issue only occurs when you attempt to connect your Mac to the Internet ... correct? That is, no doing so, it runs just fine?

If that is the case, I will need to know a bit more about your network. I'm already familiar with your Mac's capabilities, but what (when using Ethernet) is/are the hardware that it goes through to gain Internet access? For example, do you have it connected directly to the Internet gateway? If so, what is the make & model of this device? If it doesn't directly connect, what else would it be connected to ... an Ethernet switch perhaps?

Do you use your ISP's DNS servers or use custom ones? Do you employ a separate DNS/DHCP server on your network other than just the gateway? Do you use a dedicated ad-blocker, like Pi-hole or AdGuard Home? Is your Mac configured with a software firewall? ... or anti-virus? (didn't see this in the EtreCheck report, so I will assume the answer to that would be "no.").

I can read enough of the KP report to understand that Mac is crashing due to something obviously network-related. I have seen it in the past with Macs whose hardware is working perfectly, though it is very rare. I would not have thought it possible for a Mac to KP on a mere network connection, but in fact it can.

Since it's very unusual for Macs to crash on network services I strongly suspect something related to that Profile. I know you require it for eM client but it is my opinion to consider it a prime suspect in the difficulties you're experiencing.

I don't believe running Apple Diagnostics will reveal anything of interest, but here you go: Use Apple Diagnostics to test your Mac - Apple Support.

Are you aware that a Profile has been installed on that Mac? Does the onset of its problems coincide with its installation?

You might try reinstalling macOS. Although it doesn't usually resolve anything, sometimes it does. It's simple enough to try, before condemning what may be a perfectly good Mac that's nevertheless being affected by some unknown networking problem.

When it becomes unresponsive, try the key combination to force quit apps: How to force an app to quit on your Mac - Apple Support. It may or may not implicate a particular app as "not responding".

Ok thanks. Symptoms are leaning in favor of hardware failure 😞

I'll get back to you with a link to run Apple Diagnostics, which may (or may not) confirm that suspicion.

When it freezes in Safe Mode, does the cursor completely freeze as well? Or does the Mac just become unresponsive?

Migrating content over Wi-Fi is fine, but it is obviously subject to the vagaries of wireless communication. Suffice it to say that if there are dozens of competing wireless networks in your vicinity a wireless transfer is just going to be an exercise in frustration.

FYI, I did not restore Networking files.

Good idea 🙂

Once I am done with the old Mac I am going to restore to factory and test out all the hardware to see if the issue continues. If not, I will sell it, but either way, I will let you know the outcome.

Please do. Diagnosing that Mac's problem would be challenging enough even if you were to take it to Apple for a hands-on evaluation.

Whatever happened was somehow related to a network connection and it's something I experienced myself attempting to connect to a Windows PC. The Mac KP'd every time I tried to connect. The only solution was to avoid connecting to that particular PC.

Your Mac may work perfectly fine given a different network configuration. It's something we could explore, given enough time and effort.
