Mac OS 10.15.4: Random restarts due to panic(cpu 1 caller

And it tends to happen when you are working in smelting that you have NOT yet saved or updated... freezes, reboots and you lost not only your work, but your train of thought just went out the window.... Frustrating as heck

The sound relation might be possible, I experienced this also today, while join conference via Microsoft Teams twice, although yesterday I had this issue also with Google Chrome with 10+ tabs with video opened. And also as mentioned before with Node servers.

I've found just that sometime the audio of LG Ultrafine 5K monitor or the camera sometime is not present when I attach it to the mac.

And more I see that LG Ultrafine is shown as USB and not Thunderbolt, or DisplayPort...

Last night.. just running a spreadsheet and safari.. got the same error 8 times in 2 hours.. FRUSTRATING!! can't get any work done.

Apple can NOT duplicate the error so they are NOT willing to help and/or to exchange ANYTHING on the Mac Pro because according to them there s NOTHING wrong with the Pro.. I have documented the faults for the last 6 months.... have screen shots with the "Computer restarted because fo a problem" ...panic... and still!!!

... Ran Disk utility by itself to erase an external drive.... got a system crash....

Ran diagnostics.... came back in as a system crash, same thing ... panic...

Apple Support says I need to reinstall everything from scratch again... and re install WITHOUT using Time Machine..

We HAVE TO ALL DO SOMETHING AS USERS

after 30 min o a frustrating call with service were they go through the same 10 items on the "to do list" finally got a supervisor on the line.. but same thing.. if they can't duplicate the error when they connect or look at the laptop, then it's a no problem.. even with 60 documented time sin 6 months.. The best they can do is have me send it to them so that THEY can reinitialize it and test it... if they see any little ding or scratch they will blame it on me dropping it (it's on a protective case) and bill me their time... With all it's flat in Windows... at least Dell service was more cooperative and took the user's side not the company's side...

I'll keep you guys posted...

You should not disable SIP. It is not likely the cause of the crashes, but is putting your mac at unnecessary risk.

In the rare cases one might need to circumvent its restrictions (which, in my case, has been... none), you should immediately reinstate it after you did whatever you had to do.

You should uninstall the WD software. Disk manufacturers' software are not needed to work with your drives, have been known to be prone to issues, and this is a potential source of crashes - which can lead to data loss.

Sorry but what do you mean by SIP? I will uninstall WD software. I installed because I can't mount my WD Passport External Drive. Apparently there is a bug Catalina can't mount them.... *rolling eyes*.

As Barney said, your drive should not need any software to mount in macOS.

SIP stands for System Integrity Protection and is an important component of macOS security, that prevents tampering with system files.

Yours is disabled.

The standard way to reenable it is to boot into Recovery, open Terminal, type

csrutil enable

and then restart.

The drive it's not defective. I can still use it perfectly on other computers. There are thousands of threads on the internet and this forum about that topic. Tried with two different drives from WD on TWO different Macbooks with Catalina. Cheers

Is SIP the "allow apps downloaded from: "? That's all? I do want to install from anywhere while taking cautions.. If its something else I'd appreciate if you tell me. I've been a Windows user for 20 years, first time on Mac..

No. That is "Gatekeeper"

You probably had to turn SIP off to make select that "everywhere" setting of Gatekeeper; but as I said, you can and should turn it back on again; the choice you made regarding Gatekeeper will persist.

[Not that it is a big problem leaving Gatekeeper at "App Store and identified developers"; you can STILL launch any application you want! All you have to do is, for the first time you launch only, control-click, choose Open and confirm. Subsequently, you can launch by double-clicking or any other method you prefer.]

I have drives from several different manufacturers (none of them WD, because they make crap). Not a single one has a problem with Catalina.

Cheers

Congratulations to you! I was talking about WD drives which you don't have so why affirm something you don't know?

"No, there isn't. If the drive needs some software to mount, it is defective." by Barney

Cheers. Stay humble.

tried it.. did NOT WORK.. gut good luck.. this is so random that different things work for different people.. sometime I've seen a fix work for 1 week.. then out of the blue it happens.. first sparsely then more often.. then ALL DAY LONG

Strange thing.. had an external Seagate 4TB .. all of the sudden it STOPPED working on my Mac Pro.. I took it off and my laptop did NOT FREEZE all day long.. connoted the drive again.. could not see it.. connected it to an iMac.. the drive worked.. 6 Hrs later... my MacPro died again... panic.....just got a box from Apple, sending it for "diagnostics"
