macOS Big Sur - No clamshell mode...

[Wozzy]

Clamshell mode seems to work on M1 on macOS 11.3 RC, DL Manager 1.3.

Only tested 1 additional screen but its working fine. If my M1 is the main screen (dock is on it) and I close the lid it transfers to the external screen.

That's good news! I'm assuming all work fine on the latest update macOS Big Sur 11.3 11.3 with currently availavle DL for download driver for M1?

I've been using Amphetamine (from App Store) with unticked "Allow system sleep when display is closed" when sessions's started to run my MacBook Air with the following monitors in clamshell more:

1 x Dell U4919DW 49 inch suported by M1 native single external display and charging via single bi-directional USB-C cable connected to top USB-C port

3 x Dell U2515H 25 inch DL driver using via 10in1 UGREEN USB-C hub and Startech USB-3.0 to DP hardware connected to bottom USB-C port

Cheers,
David

ps. there's a thread where we drop messages about macOS and DL updates and whether anything breaks after updating:

Big Sur 11.3 update and now my previously working in 4k screen LG 27" can now only run in 1920 x 1080 - so I'd say be very careful with the update, backwards step for me, very disappointed.

@KatarzynaKowalczyk is there any update that can be provided on when clamshell mode might be supported for Intel-based Macs on BigSur?

I've just purchased a Dell D6000 and found that it's about as useful as a brick since it doesn't support clamshell mode. Didn't even consider that I'd need to review the fine print in the release notes for a 3rd party driver to find out this limitation that impacts that hardware product.

Hello,

I am wondering this for a long time, is there any reason why you cannot use the MacBook with an open lid? It is another monitor that you can use - like for some less used windows.

Its' not about, why we cannot use, its more about, it was working and now not.

I have bought the dockingstation with the displaylink only because of this.

It was working before Big Sur and now not. I'm having now also high CPU usage with the display link driver 1.3.0. This is just sad.

Works ok for me. No problem at all. Everything latest updates.

Finally! After a lot of trial and error, this works perfectly for me.

I've got a 2018 Macbook Pro (Intel), with a Dell D3100 dock that I use to switch between my Windows (XPS 13) & Mac (both required for work).

Using Amphetamine, with a trigger setup for when the dock is plugged in, and "Allow system sleep when display is closed" un-ticked, everything is hunky dorey.

Thanks David!

Thanks for the tip but this sounds like a workaround to an unsolved problem in clamshell mode similar to what I'm going through with an 2019 intel Mac -- everything works in clamshell mode until the system decides to sleep or when I logout and manually put it to sleep.

A laptop with Displaylink should be able to sleep and wake up from sleep without impacting how displays are "seen", without impacting Screen Recording permission for the Displaylink Manager app, and without requiring users to power cycle their firewire docks that depend on Displaylink to work properly.
