Panic report Mojave / Symantec

Hello, were currently using Mojave in our environment. As well as Symantec 14.2 RU2.


Here's a crash report on the same iMac that we had a fresh install on. Any help to figure this out, would be detrimental to our environment. We have multiple trashcans currently on our network for Media purposes. Ideally we would like to keep Symantec on all hosts machines. Can anyone give me a clue if SEP is causing this?

Uninstall Norton/Symantic anti-virus. It is by far the most frequent anti-virus package to cause macOS to panic.


Do not install any replacement A/V as you are just covering up the perfectly good macOS provide anti-malware services, and wasting CPU, memory, I/O bandwidth and network bandwidth.


The first panic is Symantic. It is in the kernel backtrace:

      Kernel Extensions in backtrace:
         com.symantec.internetSecurity.kext(10.0)[F3A93911-8D09-314D-9A38-9918465E3F83]@0xffffff7f8faec000->0xffffff7f8fb0bfff
         com.symantec.ips.kext(10.0)[DB4A7406-6C08-3C1A-B9CC-C828A198C0B5]@0xffffff7f8fb0c000->0xffffff7f8fb16fff
            dependency: com.symantec.internetSecurity.kext(10.0.0)[F3A93911-8D09-314D-9A38-9918465E3F83]@0xffffff7f8faec000
            dependency: com.symantec.SymXIPS(9.0.1)[57E63AE5-3611-3888-AB74-1498668DA171]@0xffffff7f8fa22000


The second panic is still most likely Symantic

sfree on invalid allocation

because Symantic is known for not being careful about accessing an used kernel resources. In this case attempting to free memory that has already been freed.


Just say NO to 3rd party anti-virus, Mac cleaners, memory cleaners. They are just going to cause you pain.
