MacBook Pro 2017 15" kernel panic after going to sleep

Hey Guys,

I am following this issue and looks to be only affecting T1 and T2 equipped Macs.

That includes

• 2017 iMac Pro
• 2018 Mac Mini
• 2018-2019 Macbook Air
• 2016-2019 MacBook Pro with Touch Bar.

Anyone that installed the update can you check something? I want to see if the Security Update installer created a tmutil 24 hour snapshot.

Run this command to check

tmutil listlocalsnapshots /

You should have a listing from the past 24 hours. If you do you can boot into the Recovery Partition and restore to this snapshot before the update was installed.

I am following this issue and updating when I find new info here.

I have updated the main article on this issue.

It seems like we only have 2 "workarounds and 1 solution.

Workaround

1. - Check the box "Prevent computer from sleeping when display is off"

2 - Don't close the lid but instead click the Apple icon > Sleep

3 - Reset SMC (only seems to work for 50% of users)

Fix it right now

1. Upgrade to Mojave 10.14.6

Hopefully we get a new updated 2019-004 Security Update quickly next week.

Update for me: MBP 2016 Touch Bar that was on High Sierra. Note that there are no Beta versions of anything involved. I was on High Sierra running perfectly and noticed in software update there was a security patch and a safari patch. After running those I had the KP on wake from sleep issue. Resetting SMC and PMU did not solve the issue. I just updated to Mojave and it is no longer an issue for me. Initially the Touch Bar wold not show the finger print arrow, after a restart it behaved normally

You could try booting form an external device first.

I had these constant kernel panics when sleeping on my machine ("AppleACPIPlatformPower.cpp"). First I thought it could have been an Apple Update as I had Catalina once installed on a second partition of my main SSD. So I remove the partition, did Disk First Aid, PRAM, SMC, reinstalled High Sierra in the hope that it would fix the issue. Nothing.

My next steps:

• Startup up from a fresh High Sierra on an external USB-SSD drive -> same Kernel Panic when sleeping
• Startup up from a fresh Mojave on an external USB-SSD drive -> same Kernel Panic when sleeping

After backing up to TimeMachine:

• Wipe of internal SSD and fresh install of High Sierra -> same Kernel Panic when sleeping

Next: Apple Store. They said they need to replace the mainboard.

I did some additional digging and found multiple reports of this issue. Most (if not all) are related to system updates, but not this specific one. Some also target other MacBook Pros (2016 models and a report of a 2018 model).

The only solution seems to be a Logic board replacement (that's bad news if you're out of warranty, but it's an Apple update that caused the problems so they should cover it).

This is likely what happens:

• With the latest updates you likely noticed a lot of restarts (these are intentional)
• In one of these restarts something went wrong (maybe a short circuit)
• Something broke down that's needed when waking from sleep (might be a specific temperature sensor from 1 report)

If you have this issue and Apple (or your service provider) tells you to either...

• Restore your system
• Upgrade to Mojave
• Wipe your entire HD
• Do a hardware test
• Reset NVRAM
• Boot from an external device

...don't bother. It won't help. Just point them to this topic and answer and say they need to replace your logic board and that security update 2019-004 for High Sierra should be pulled (at least for the 2017 15" MacBook Pro). Although the issue is around for multiple years the reports seem to exponentially increase with this specific update.

Encountered this exact issue after installing security update 2019-004 on macOS High Sierra on my 15" MBP 2017. Consistent kernel panic every time after waking up from sleep mode.

Upgrading to Mojave resolved this issue for me.

@Fugge, I had the same problems after installing the High Sierra security update a few days ago. In fact it's like a Déjà vu for me as my Macbook kept going into kernel panic shutdown when I installed the previous security update back in April 2019. I had the mainboard replaced by Apple (thankfully my warranty was still in force so I didn't have to pay for the repairs).

Thanks to you for posting this issue (and the many other Mac users who also reported the same problem) - for once I have affirmation that it's not likely another hardware issue with my Macbook (which, starting from the first couple of months of getting my new macbook, I have had to send in for repairs and replacements of supposed hardware faults on at least 5 occasions over the past 1+ years).

Working on the premise that it's likely a software issue (and not wanting to spend another 2 days of troubleshooting and running back and further to the Apple repair centres), I'd just upgraded from High Sierra to macOS Mojave, and thus far it seems to be stable (no more mysterious shutdowns each time I step away from my Macbook for a few minutes); so I believe I might have successfully resolved the problem I had been facing with this week's High Sierra security update (fingers crossed🤞).

You might want to consider this approach if all else fails; or if you do not intend to spend hours trouble shooting the problem (in which case I'm sure the good folks at Apple Support will be happy to support you along the way if you want to try troubleshooting).

Update: I got my Mac Book Pro (2017) back from the Apple Store. They replaced the mainboard for free.

The problem has gone now, same system 10.13.6, backup from Time Machine, no longer kernel panics after going to sleep.

The mentioned security update seems to have flashed the firmware of any component of the board in a bad way. Therefore simply going back to an old TimeMachine backup or booting from a freshly installed Mac OS does not cure the problem. To all the people out with that problem: save your time!

No word from Apple how they plan to reverse that so far. They need to release a firmware updater for all affected machines.

I can confirm that an update to macOS Mojave from High Sierra with the Security Update 004, does indeed fix the kernel panic upon waking from sleep...

Sad that Apple couldn't do this PROPERLY with the 10.13.6 Security Update 004... oddly enough, that 004 update works just fine on my 2008 MacPro running High Sierra using the "macOS High Sierra Patcher Tool for Unsupported Macs".

Yes, a Time Machine restore *DOES NOT* fix this issue. Why? Apple seems to have applied a firmware update to an internal component (T1/T2?) that lets your Mac crash on sleep, no matter what kind/version/lfavor of system (High Sierra, Mojave/..) you are booting of at any later time.

I guess only a firmware update or a mainboard swap can fix this issue. My MacBook Pro is currently at the Apple Store for a mainboard swap.

very useful lesson from this: with Apple software updates always wait some time before installing...

User @g--unit posted this possible workaround.

Link to this Post

""I was able to get the shutdowns to stop by disabling computer sleep when display is off.

system preferences -> energy saver -> check "Prevent computer from sleeping when display is off"

Not a solution, but at least stops the annoying shutdowns until Apple can fix the issue.""

Curious to see if this works for others! Looks like the option is only available if the Mac is connected to power. I am not sure what would happen if you try this on battery.

This is working for me right now, it's a workaround and not satisfactory, but at least I'm not sleeping and panicking on wake. Looking forward to a solution from Apple. Basically I'm preventing the computer from sleeping automatically when the display is off. I also use Black Screen screensaver to turn the display black instead of running a screensaver that might take up cycles and burn up my display.

Just tried again resetting the SMC on my 2016 15" MBP - The T1 doesn't seem to respond to this solution...

On my MBP, checking the 'Prevent computer from sleeping...' workaround doesn't work either, I typically had that checked anyway along with 'Wake for Wi-Fi...' and I've tried with and without that checked.

What has worked for me was installing macOS Mojave over a pre-security updated cloned backup. I've read elsewhere that a proper fix will hopefully become available in the coming week... I hope so, I'm not impressed with mojave, Apple has a very bad habit as of late of removing functionality with each successive OS.

Same issue for me after installing 2019-004 on my 2017 MBP 15" running High Sierra. Rock solid before that update, now it panics on wake from sleep. SMC reset didn't help. Sure hope Apple pushes a fix for this since upgrading to Mojave isn't particularly convenient right now.
