First off, having owned MacBook Pros since about 2002 (power books), this is by far my favorite MacBook Pro and I do not plan to return mine. The case, screen, keyboard, etc all are flawless... My specs are loaded... 2.4, 64GB, 8TB... not a single BridgeOS error in sight after 1 week. :D Love the 8TB, have moved all my photos off my NAS and onto my MacBook, its pure heaven. Can’t wait to make it mine even more!

My only issue so far, and it’s surely software related, is if I leave the MBP connected to the Dock, I get a CPU panic/crash. My 2017 did this for the first 6 months or so until the bugs got worked out. Wondering if anyone here has had the same issue?

My dock is the first generation OWC Thunderbolt 3, 65W Charging. I have my OWC Thunderbay and a few other things connected to the dock. Thank you guys for any feedback.

Error report looks like:

I'm having the same issue. I had an almost fully loaded MBP16 (only 2TB instead of 8TB) since launch and I've had random panics after returning to my computer. After a while my MBP just wouldn't boot at all anymore, took it in to the Apple Store and they couldn't even diagnose it. Now I'm waiting for my replacement.

I'm worried now because my loaner MBP16 has just started causing the same issues, so I'm thinking eventually there's a chance the MBP will fail again.

I have two TB3 docks, and it only happens when connected to one, my AKiTiO Thunder3 RAID STATION which has a 2TB HDD and 256GB SSD. When using only my other TB3 dock (Kensington SD5000T) I haven't seen the issue yet. All the times I've seen it I come back from being away from my computer, the displays have been asleep and the MBP has already rebooted itself from the panic.

My panic logs are almost identical to yours.

After reading around I'm wondering if it's one of the drives in the AKiTiO dock, the 3rd party SSD.

Multiple hangs/Kernel panics on reboot?

Hi Everyone, I updated my 2012 MacBook Pro to 10.15.1 and rebooted after some lengthy uptime [a few days], and on reboot, my system hung about 3/4 of the way through the loading of the OS, and after awhile kernel panicked and rebooted. This continued a few times [probably six times?], and...

So after removing the SSD from the dock, I still had the issue. So I removed the WD 2TB Green drive I use for time machine and I haven't had the issue since.

Going to try putting the SSD back in and see. Maybe there's an issue with the 2TB HDD in the dock.
 
For now, I just went into System Preferences>Energy Saver>Power Adapter>Ticked the box "Prevent Computer from Sleeping Automatically when the display is off" and I have no issues whatsoever. I'm not going to return this computer for something that is clearly software related.
 
MacBook Pro 2017 15" Bought Refurbished at the Apple Store.

Having the same issue with my OWC dock Thunderbolt 3 also first generation. Could it be a thunderbolt incompatibility?

Here is my log:

Always happens when computer is falling asleep, it used to work when i turned power nap off and it didn't restart randomly, but like you discovered above one of the MacOS updates apparently rolled back driver changes or improvements to the thunderbolt drive IOAHCIBlockStorageDriver.cpp is useless.

This setting made no difference for my crashes and random restarts.
 
I'm sorry to hear that turning off sleep hasn't solved the issue for you. You might want to check your thunderbolt cables, loose cables can cause crashes. OWC even makes some little sleeves to make sure the cable's are not loose.

I'm very interested in how you got a "loaner" MacBook. What did you tell the people at Apple?

There is a known issue with that OWC thunderbolt dock. People have had problems with them. See here and here.
 
@Glockworkorange thank you for the links and the post. My system runs more or less stable with the OWC dock, but if I try to use sleep then I get a crash. I had a horrible time with the Caldigit dock a few years ago, but at least their support bent over backwards to try to help me. OWC just points a finger and moves on. I have had other bad experiences with OWC support on other products in the past.

With no dock, my MBP sleeps great. I bet I know one TB3 dock/device that will work great, the Pro Display which I have been thinking about buying anyway. If the display had 120Mhz, and more ports I would be all over it. Can you imagine that dock with faster refresh and more ports?

Yeah, the Thunderbolt docks are finicky. I had a USBC C dock from OWC with sleep problems. Their remedy was to update the dock...using a Windows .exe file!

I will never buy another dock from them again.

The LG Ultrafine 4K (the newest one) has TWO Thunderbolt 3 ports and 3 USB C ports. the Pro Display XDR only has ONE Thunderbolt 3 port. Can’t recall what you need the dock for, but the sort of Apple Approved monitors might do the trick

so can you update the thunderbolt 3 dock with a windows computer, and it will still work with the MacBooks?

I took my broken MBP in to the Apple Store and they couldn't even start it up to use their in house diagnostics utilities. The essentially gave me a brand new out of box one to use until my replacement arrives (because it's a custom order).

So far checking "Prevent Computer from Sleeping Automatically when the display is off" has worked. I usually always have that checked so I'm guessing it unchecked when I migrated to the new 16" MBP.

That's awesome. They've never done that for me. In the event one of my machines breaks, I will push for a replacement.
 
Staring at my OWC dock now, I do wish my computer could sleep... it might be time to revisit this situation.

tried different cables and same result, for me the use case is i typically don't move my MacBook ever. So its a desktop computer plugged into the dock. The cable is never removed.

same issue, i have both OWC thunderbolt bock 2 and 3 and my 2018 MBP with t2 chip freezes and crashes randomly but most often when th computer is asleep, sometime once a day, sometime once and hour, so frustrating OWC disconnected all good, no crashes. Is there some firmware update of fix?
 
I'm going to start testing my dock with different things plugged into it after I'm done moving my Time Machine Backus to a new larger drive. Already, I have disconnected my Thunderbay from my OWC dock and plan to keep it that way. I also connected the USB-C Dell Monitor to the dock, and dock to the MBP. Where I had the thunderbay connected to the dock and monitor (100w charging) to my MBP.
 
I'm wondering if Titan vs Alpine ridge makes a difference. I think most of these docks use the older Alpine Ridge, with only a few new docks out there using the newer Titan Ridge chipset. Any thoughts guys?
 
I wanted to come back to this thread and say that my 2019 16MBP now sleeps and wakes correctly with the OWC 3 Dock. It even sleeps with my external HDDs connected. If this changes, ill update here again
 
Was a 10.15.4 bug, only needed to sleep when attached to power to trigger the panic. A temporary work around was to disable "Power Nap". Fixed with 10.15.5.

My 2019 16inch now sleeps with both my OWC dock and OWC Thunderbay connected. I’m actually pretty surprised, but for whatever reason, MACOS got serious about fixing sleep? I’m afraid to ever upgrade again
