Kernel Panic Mojave

[hughvane]

Mac Mini 2018 with OS 10.14.6.

If put to sleep, or perhaps left unattended for 15 mins or more, the Mac restarts itself, requiring a login every time. This is more a nuisance than a problem. The crash report states a Bridge OS issue, and there is a suggestion that it is directly related to the use of Safari 13.1.1.

The issue has been reported to Apple (several times by me), others as well, but there's been no response from Apple other than discussion on its support forum and here: Mac Mini 2018 Kernel panic bug_type 210 after Security Update 2020-002 | MacRumors Forums

Hopefully someone here on MF has a permanent solution, Apple doesn't seem in a hurry to issue a fix which is believed to have been a bug in a security update.

Thanks for any assistance offered.

I'm using a 2012 Mini with Mojave so I guess I don't have this problem, but would not putting the Mini to sleep ever not be a work-around for now?

I have my Mini set to never go to sleep and only have the monitor go to sleep after 10 minutes.

Thanks. I used to shut down the '18 Mini overnight, but was advised that it's better left operating, but in sleep mode, so that the network was also in sleep (ie. no 'intrusions'). Things were fine for months until the latest security update, which is the probable cause. I am giving the No Safari browser a trial (hasn't worked yet), and will see if/when Apple issues a bug fix.

That doesn't make sense to me.

The obvious solution would be to use Recovery to reinstall the version of Mojave that your Mac came with, and then just not let it install subsequent security updates.

My wife is nervous about that as well - she just turns off WiFi when she is not using any network services.

But it sounds to me that Randy has the obvious solution.

Update - thanks to the suggestion from someone on a different forum, ceasing the use of Safari seems to have worked, no further kernel panics and reboots are occurring - so far!

When attending a locally-run course on prevention of online scams, one of the instructors recommended to those in attendance that for security reasons it was advisable to power off either the (wired) router, which I do, or the computer, which I do not. Instead I put it to sleep, or simply leave it be, and after a period of inactivity it puts itself to sleep.

I'd love to hear *exactly* what they expect to happen when your computer is turned off. I think that it's a load of bullhockey.

I've been assisting and communicating with ten of thousands of Mac users consistently for well over 30 year now, and I've yet to hear of a single believable case of an ordinary Mac user being hacked in any case.

I agree with Randy. Besides, modern routers have built in NAT which blocks intrusions. And as long as you use strong encryption (WPA2) no one is going to be able to jump on your WiFi signal. But if it makes you feel safer, there is no harm in turning off your router.
