Panic CPU CATERR detected (error)

Hi,

It seems to me, it's a hardware, CPU issue. Following document could help your question.

You'd better contact Apple support or take your MacBook Pro to Apple Authorized Service Provider to be examined it.

Or if your country's retail Apple Stores are open, make Genius Bar reservation to ask about the crash.

I have a 16", had this issue from the start, posted some screenshots, & I handed my macbook into apple a few weeks ago. I attempted to perform a full-fresh install (delete partition, reinstall) and it was crashing. No updates - it still in Houston. Get your macbooks in for service and/or extend your apple-care

I have this issue too with my MacBook Pro 16' 2019 that I bought end of March 2020.

I tried everything including clean installation of the lastest MacOS, no installation of software, no attachment of any USB devices except the original power supply. Even though I just used safari and mail the device panics many times each day.

I called Apple support and they said it must be a hardware issue.

Replace logic board

No answer as yet. Crashes only happen when I Use my eGPU (Sonnet 650 + Radeon Pro Wx7100

Hello, had the same problem for a few months now on Catalina OS on a MacBook Pro 2018 15".

I found a fix for it - I installed the BETA version of Big Sur (20A5395g), which is pretty stable and received no panic attack after leaving the laptop to sleep even overnight.

If you want to do it, keep in mind that this is a BETA OS and you are taking a risk by installing it.

If you haven't yet registered as a developer you need to enroll in the program - here.

1. Go to developer.apple.com
2. Click on Discover > macOS > Download and sign in with your developer account or Apple ID.
3. Click on Install Profile to download the new macOS Developer Beta Access Utility to your Mac.
4. Go to Downloads on your Mac and click on the new macOS Developer Beta Access Utility to open it.
5. Double click on the macOSDeveloperBetaAccessUtility.pkg and the installer will run.
6. Once new macOS beta is installed Software Update (in System Preferences) will check to see if there are any updates. Click Update and the latest version will download.
7. You'll see a prompt to install the software, click on Continue.
8. Agree to the Ts&Cs (more on them below).
9. Click Install.

Hey!

I've recently found out, if you are using any legacy software, that is, a software that uses kernel extensions or that software has not been updated for Big Sur, uninstall it. I was using McAfee Total Protection that hadn't been updated for Big Sur, and after uninstalling it, no more panics.

Thanks.

Apple needed to replace my logic board... I haven't had any major issues since the fix

Hello,

Try running EtreCheck and read the report, and read the section that requires immediate attention. When I ran it to fix my MacBook Pro 16'', It showed me a bunch of Adware, 32 Bit apps, etc etc... After deleting all those files and apps, I haven't had any kernel panics...

Just try it

Thanks

I've had the same issue in the last two days.

I have my MPB 16" 2019 which I use with an old 27" Thunderbolt display. What I usually do is this:

• I lock the screen
• I close the lid of the laptop
• I unplug the monitor
• I unplug the power
• Sometimes I have my airpods box plugged in and I unplug it as well.

So far, I didn't pay close attention to the order but I usually I unplug the monitor first then the power.

Also, I never got one while I was working - I've had the laptop since August 2020.

I sent the report to Apple.

I think I’m more lucky.

After upgrading to Big Sur, I don’t the issues any more.

But still keep monitoring

i had my logic board replaced

I had this problem in osx Catalina. Nothing could solve this except clean installing osx BigSur.

Have a similar issue. Happens to me when I plug/unplug my Thunderbolt dock.

Doesn't always happen, but seems to be a similar pattern.

• Plug in to dock
• Monitor works fine, peripherals don't
• Unplug from dock
• Plug back in
• Fans spin up real quick, system restarts

Only things I have connected to the docker are a set of headphones, ethernet, and my monitor.

I was working for multiple days on my MBP without an external monitor. Added on an external monitor and within 24 hours I had (2) of these kernel panic errors... Wondering if there is anyone, with a MBP, who is not using an external monitor and experiencing this issue...
