MBP 16" kernel panic - Issue 1

Currently i have 10.15.5. After upgrading to 10.15.5, i am seeing this issue.


Tried the following:

  1. Reset SMC
  2. Reset NVRAM
  3. Safe mode
  4. Uninstall most of the softwares i had.


(Don't tell me to reinstall the OS)

1. No. It does not panic while booting into safe mode.

Then it's probably a third-party kernel extension, but you already said you uninstalled software. Maybe you didn't uninstall the system modification that installed a kernel extension.


Post the rest of the panic log (use the Additional Text area in toolbar), or just look in the loaded kexts section for any third-party kernel extensions.
