E7470, In Memory Panic Stackshot... while upgrading to 10.15.3

Recommended Posts

Installed Catalina 10.15.2 a couple of weeks ago following Jake Lo's guide.

It was working flawless.

Now that I saw that the update to 10.15.3 upgrade was like a walk in the park as long as I updated Clover, kexts and repaired permissions and rebuild cache I decided to take my chances.

So, I checked Clover, was latest version already. Updated a few kexts with the help of Kext Updater app.

(For some reason it wouldn't boot if I moved BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext. I now have BrcmFirmwareData.kext and BrcmPatchRAM3.kext in my "Other" folder.)

So, even though I have all my kexts in the EFI partition , I ran the following just in case:


sudo chmod -Rf 755 /L*/E*

sudo chown -Rf 0:0 /L*/E*

sudo chmod -Rf 755 /S*/L*/E*

sudo chown -Rf 0:0 /S*/L*/E*

sudo touch -f /L*/E*

sudo touch -f /S*/L*/E*

sudo kextcache -Boot -U /


The upgrade started and rebooted, then got stuck.

I can still get in to the 10.15.2 installation so I set the boot mode to verbose and restarted.

Now it tells me:

** In Memory Panic Stackshot Succeded ** Bytes Traced 30512 **

Try disabling some unnecessary kexts until upgrading is done.

At Clover screen

Hit spacebar -> Block injected Kexts

Select the Folder where kext(s) resides ( Other, 10.13, 10.12…etc)

Select kext(s) to be disabled

Go back to main menu and boot with selected option

Some unnecessary?

I tried disabling them all, no luck.

Tried disabling some random ones, no luck.

Tried the option to boot without injected kexts, no luck.


When booting in safe mode I get some more info on the screen if it's of any help?

Sorry to say, still no luck.

All kexts but VirtualSMC disabled, same output.

Boot option -igfxvesa, same thing.

Will try to do a complete reinstall with 10.15.3 instead on another disk and see if that helps.


Will let you know in a few hours or tomorrow.

Thanks for your superb guide on installing on this computer!

I remember my first hack, it took weeks to get it working right.

I tried a fresh install, same thing.

I spent countless hours yesterday trying to figure it out, nothing.

So I thought, "What is different with my setup compared to a default machine?"

Oh... the wireless card (DW1820A).

Disabled it in BIOS and... Voila!

The update installed just fine!

Enabled it again and still booting just fine.
