Last week I got the new 16" MacBook Pro and most things are working well. I get to work this morning and plug it into my dock with my 24" 4k screens (2) and it works fine until I close the computer for clamshell mode. It freezes then. I can move the mouse but nothing responds including the MBP when opened back up.
Anyone else having this?
I have the monitors set at full resolution.
I found out one thing that if I use my iPad Pro, using sidecar, and I forget to "disconnect" from the menu, then the computer will freeze like before when I connect it at work, but I can reboot and then it will be fine.
I did reset my PRAM right after installing 10.15.3.
Here is what my setup looks like:
Same exact issue here! Apple, please fix this! The display / graphics drivers are completely broken in clamshell mode.
This morning I plugged in my 16" MBP, already closed, and it worked for the first time. This gives me hope that it's resolved!
I am very interested to hear your results. I do wonder if this is a MacBook Pro issue since this is a brand new model, a CALdigit issue, or a macOS Catalina problem.
Unfortunately this is going to be a difficult one to test each of the variables considering we can’t take the 16 inch MacBook Pro back to Mojave.
I opened a ticket with CalDigit and they had be try several things (none worked) and send them crash logs. That was before thanksgiving so I haven't heard anything new.
This morning I had my first time with the "constantly switch from connected to disconnected to switching resolutions between each time" which I also couldn't get passed without a reboot.
The joys of being early adopters I guess :(
I upgraded to the official 10.15.2 today. Unfortunately, the problem is not fixed. Though, it is different for me. Instead of the screen freezing but being able to move the mouse, the screens go black as soon as it's in clamshell mode. I tried it with it being already connected and then shutting the lid and then trying it where I plugged it in after the laptop was already closed. Both resulted in the same effect.
Although I have not studied the problem as well as the others on this post, I have found my new 16" MBP hooked to my CalDigit TS3+ locked up when I go to work with it in the morning, of course it went to sleep at night. Also, it won't even shutdown without disconnecting the TB3 cable to the dock. Apple, please help get this fixed! This ruins my remote utilization of this setup.
In my case: I had already enabled that setting, I don't allow them to go to sleep because of problems with screen orientation on wakeup (i.e. screens out of order). So this has no effect on me RECONNECTING my laptop in clamshell mode to the TS3. I can disconnect without an issue.
Hopefully, 10.15.3 will come along soon. Though, we haven't had anymore betas since mid-December. Last year the final release of 10.15.3 came out at the end of January. I see that Apple sells the CalDigit TS3+ so it's not like it's an out of date peripheral.
Has there been any solution to this? My external screen or computer does not freeze but it flickers every 5 seconds which is annoying to say the least.
Quite a bummer to buy the top of the line MBP 16" and have this problem upon coming home.
Looking forward to some sort of solution.
Hi everybody, so I have 16" Macbook Pro (2,3 i9 ; 8GB graphics) and when I connect 4 external displays(only FHD) it's freezing, and when I run som videos with Quicktime, or VLC I have drop frames or it's freezing for a second or two. Does anybody have this issue?
Thanks for the good news and update bryce! Can you list which steps you did to get it to work? Which versions of macOS are you on? I will test out clamshell later when I am at home - so far, have been running my laptop open.
Thanks for the update. I updated my firmware and OS, went home, and my laptop still froze upon clamshell mode... What resolution do you have your monitors set to?
For the record, I'm using three 4K monitors. Two through the TS3+ (DP to DP and DP to USB-C) and one monitor directly (USB-C to USB-C).
Nice job Zelph. I'd think the Caldigit is not going to rectify itself.
Apple saw the thread and they reached out to me. Hopefully they contact you too and we can get this solved.
