clamshell mode

Is it possible to have the MBP sleep whilst in clamshell mode (power always connected) and waking it up with an external mouse and/or keyboard? If so, how does one achieve automatic sleeping? By turning off the "Prevent automatic sleeping on power adapter when the display is off"?? And if so...

I run my Macbook Pro with M1 Max in clamshell mode most of the time and have a Caldigit TS4 Thunderbolt dock and Apple Studio Display connected. Until recently, I was able to unlock the Mac using my external Touch ID Magic Keyboard. Now this seems no longer possible. I have to enter the password...

I'm wondering if anyone else has experienced this. I was running dosdude's Mojave on it before OCLP & clamshell mode worked fine. But now, with OpenCore Legacy Patcher, it doesn't work any longer. When I close the laptop (15 inch Macbook Pro 2010 6,2) it stays active. Is there a setting I'm...

I am having a problem with my MacBook having crashed sometimes when I wake it up from sleep. I am running an M2 Max MacBook Pro 14" on Sonoma in clamshell mode, connected to a CalDigit TS4 dock, which feeds my Samsung CJ791 monitor via DisplayPort 1.4. I have tried another monitor using HDMI...

I've used Macs for over a decade in clamshell mode. The Sonoma update causes a crash/kernel panic on startup. I can no longer login using the Apple wireless keyboard and external display via Caldigit TS4 like I used to do. I have to open the lid, log in, acknowledge the crash, then shut the...

How works the cooling system (fans) in a MacBook Pro 14" in clamshell mode? When the screen is open the hot air comes out from the bottom of the screen. So, i was wondering how it works and if it affects the cooling when the fans are in use in clamshell mode?

I would like to buy one of the new MacBook Pro models and need some buying advice. My current setup consists of a 5K 2017 iMac (4,2GHz-Quad i7 with 64GB of RAM and a Radeon Pro 580 8GB) connected to two old external monitors (s. picture below): 21" LG Flatron E2211 in portait mode 27" Samsung...

Hi, Is there any resource that will list all the compatible display adapters with a certain MBP? I'm looking, specifically, at the MacBook Pro 16 inch (A2141) which has the Radeon Pro 5300M as its GPU. I'd be looking to connect two external monitors although three would be more ideal. And...

I'm running M1 MBA hooked up to a Samsung UR55 IPS 4K UHD monitor through Satechi USB Type-C to HDMI Cable 4K 60Hz adapter. Samsung has HDMI Black Level option on their TVs and monitors to "compensate for the black level range of an HDMI input". My understanding is that the option is supposed...

I'm not sure if this is normal, but I recall in older versions of MacOS that I was was still able to accept and make outbound FaceTime calls, despite my Macbook's webcam being unavailable due to clamshell mode. However, that doesn't seem to be the case anymore. MacOS blurs the caller's video...

Hello guys. After using the laptop for some days in clamshell using an external monitor (as fix for high wattage usage when using two monitors), My screen showed this strange lines and dots. I assume it was caused by heat transferred to the display. I realized this almost finishing my day work...

Hi, I've had my iMac for a few years now, and while I love it, I work with video footage quite a bit, and stills. Not having access to a HDR monitor is getting a bit on my nerves so I have been looking at buying one for myself. But I don't want it as a second monitor, I want it as the *only*...

Looking for suggestions. Running a 16" MBP since November, connected to a powered dock (+2 monitors) and a third external monitor, connected directly over USB-C. Clamshell has worked fine up until recently. Problem 1 Since 10.15.4, including the Supplemental, I can't run clamshell at all. If...

Hi Guys. I am considering a 27 inch monitor (BenQ 2720U) to use with my Macbook 2019 15 inch model. This monitor can supply up to 65 Watts through TB3 which i guess is not enough to charge my laptop under heavy loads (i think it needs 87 watts, right?) So i plan to have the laptop connected to...

Hi everyone, I’m running a High Sierra with the latest updates on my mid 2011 MacBook Pro. Generally I use this machine with the external HDMI monitor and keep my laptop closed. I have an external wireless keyboard and a mouse connected to it as well. This setup was running beautifully for...

I currently own three older MBP models. I really don't know what to do with them. I've considered setting them up into dedicated clamshell modes around the house but I don't know if with their specs its worth it. If it is, may you please recommend setups, peripherals, and generally any info/...
