MacBook Pro M1 Pro issue with dual display after updating to macOS Sequoia 15.1

As per the hopes you expressed in your original, unmoderated post which Apple emailed to everyone watching this topic - you are correct, it has indeed been resolved in a later version, we're just not allowed to talk about it (even though every OS X user world-wide is allowed to install it ;-)

How did you manage to revert back? I wish I could go back to Sonoma

Try going forward instead of backwards. See the post above by urchino. Let us know (and don't mention the second letter of the Greek alphabet by name :-))

2021 M1 Max MacBook 16" 64gb ram 24core gpu.

just started having the same issue last night. The difference though is I haven't updated. I'm still on sonoma because I am an audio engineer and have to wait for a while before any major updates because of audio plugins not being ready yet (it just happened ugghhh!!!)

I initially thought it was a power issue or cables because this has never happened before, but it's doing the exact same thing with three monitors and the display on the actual Mac. I do feel like it's a power issue still, but the issue being the ports because my external ssd loses signal and I get the error notification. That in itself is a. bad thing for the drive.

But again, I haven't updated and am using 14.6.1.

Also, have any of you noticed your system being sluggish as well when this started happening?

So yeah, no update, no new hardware. Everything is the same as it was when it was not a problem. uggghhh

I just updated to macOS Sequoia 15.2 (24C98) on my MacBook Pro M1, and unfortunately, the issue with the external monitor connection is still unresolved. I’ve been dealing with this for quite a while now, and honestly, I’m losing patience. I really hope Apple can provide a more effective response soon.... It's so annoying...

Hi all,

I got this issue after upgrading to Sequoia 15.1.1 from Sonoma. Intel Macbook Pro 2018 with T2 Chip

After trying:

• Reset PRAM
• Reset SMC
• Change USB-C to HDMI adapters

Nothing working EXCEPT changing the monitor, yes, I know but it happens in my LG TV QLED (60 hz) but it does not happens in a cheap RADIOLA TV (also 60 Hz), very old one by the way.

So this means that Apple has changed something that affects what.... could someone explain why a HDMI connection works in one TV and another one fails every 5 minutes?

Regards.

This is incredible!!

I updated to 15.2 and the issue dissapeared for almost 4 days, and now it happens again.... how is this possible?, I contacted apple and they told me they dont have notifications about similar issue regarding Sequoia....

I will uninstall Sequoia and will try Sonoma.

Updated to 15.2 today, problem not resolved.

In fact, it's worse now; before my screen went black for a few seconds, now it's 10 seconds or even longer.

The screen now also goes black after a few minutes of inactivity although it's set tot do that after 30 minutes.

A new problem, possibly?

How is Apple informed of this problem? Do they check the community posts or is there a way we can inform them of the issue directly?

Yesterday I was with tech support from Apple. They suggested I boot my Mac in safe mode, which didn't resolved the issue. Now shutting down the monitor and going to sleep happens not that often. I'm on a MacBook Air M1, with a Thunderbolt cable to a widescreen LG (so no option for HDMI).

Apple should know that we don't really need AI images, we need to work.

Updated to 15.4 this morning and there is no change in my problem with the external Apple 23" display connected to my MacBook Pro M1. No change. Still goes dark for 10-15 seconds every 5 minutes to 5 hours. Apple, please fix this glitch. I can't be the only one having an issue. I tried to submit to the feedback page in the Luis Sequeira1 post below, but, of course, there is no way to submit feedback for MacOS -- only iOs and hardware. Sheesh. I'll continue to be frustrated.

Is there a solution? I have two external displays - one is cnonected via a docking station through the usb-c and the other is directly connected to the Macbook pro via HDMI. The one that is directly connected via the hdmi is the one that goes off and on....

15.4.1 this evening. Still. Not. Fixed.

Apple 23" (my M1 2020 MacBookPro calls it a "Play").

Tried two different DVI to USB-C adapters.

Tried different resolutions on the external.

15.4.1 this evening. Still. Not. Fixed.

I’m having the same issue with my MacBook Air M1. I connected a widescreen LG monitor using a Thunderbolt cable, and it’s frustrating af.

I have the same problem with an HDMI to USB-C adapter. It worked fine before 15.1 but now I can't use my external display. Does anyone find a solution ?

Updated to 15.2 Beta 3 and problem persist.

Used Amphetamine but still no solution.
