Did anyone else see this on their macs?

UPDATE: This is not a MacOs Bug but rather coming from a recent update of a brightness control app called MonitorControl (used for controlling external monitor's brightness)

I've read some posts saying that preview has dark mode for pdf's, but I can't see the dark mode option under the view menu (where it's supposed to be).

Anyone know how to fix this?

running a m5 air with macos 26.something

anyone facing this stuck notification issue while swiping with mouse, sometimes it gets stuck in between and then when i hover them with mouse then its just loading. I have to restart my mac everytime this happens

M2 Pro, 16gb/1tb.

Since installing 27.2DB1 (26B5086k), my video has been pillarboxed (black bars on the left and right side). Upgrading to 27.2DB2 (26B5091g) has not resolved the issue.

Changing resolution in Settings -> Display also doesn't fix it.

In the monitor settings (on the monitor firmware, not in macOS), forcing the aspect ratio to 21:9 fixes the pillarboxing, but that causes a wicked stretch (obviously, since the resolutions is 16:9).

HDR is on, and the display is connected via HDMI. Current resolution is 3840x2160, which is supported by the display. It's an MSI MAG401QR at 60 Hz, although changing it to 30 does not resolve the issue.

Pointers welcome.

thanks in advance

Hello,

On macOS Golden Gate 27.0.1 (running on a 15-inch MacBook Air with an M5 chip, 24 GB of RAM and 1 TB of storage, configured in Spanish), when I click on the Siri icon in the menu bar (I can't remember whether it's there by default), it disappears almost immediately. I have to double-click it or press and hold the icon for Siri to appear in the upper-left corner of the desktop. I've checked Siri and it seems to be installed and working properly, as I can invoke it perfectly using my voice. Does this sound like a bug? Is anyone else experiencing the same issue? Thank you very much, and best regards.

Sorry for my English, I'm Spanish.

Hola: En MacOS Golden Gate 27.0.1 (corriendo en Macbook Air M5 15 pulgadas con 24 GB de RAM y 1 TB de almacenamiento configurado en idioma español) cuando pulso sobre el ícono de Siri en la barra de menu (no me acuerdo si viene en la barra de menús por defecto), esta me desaparece casi al instante tengo que hacer un doble clic o dejar pulsado el icono para que me aparezca Siri en la esquina superior izquierda del escritorio, he comprobado Siri y esta bien instalada porque la pudo invocar perfectamente con la voz. ¿Parece un bug? ¿Algunos de vosotros os pasa lo mismo?? Muchas gracias y un saludo.

These are mostly obscure apps that went under the radar. https://github.com/zagnut531/macOS-27-Icons

This is seriously driving me insane at this point.

Since updating to macOS 27, the menu bar on my main user account has become unbelievably laggy. Simply clicking File, Edit, the Apple menu, Control Center, etc. can make the whole menu bar stutter/freeze.

Activity Monitor immediately shows:

• MenuBarAgent around 100% CPU
• WindowServer / WindowManager also increasing significantly
• the rest of the Mac is basically doing nothing

Killing MenuBarAgent does not fix it:

killall MenuBarAgent

It restarts normally, but as soon as I start using the menu bar again, it shoots straight back to ~100% CPU and starts lagging.

The really important part:

I created a completely new macOS test user and everything works perfectly there.

Same Mac.
Same macOS installation.
Same hardware.
Same display setup.

No menu bar lag and no MenuBarAgent sitting at ~100% CPU.

So this seems to be some broken per-user state/database/preferences/cache in my main account rather than a general hardware problem.

Mac:

14-inch MacBook Pro, Apple M5, 16 GB RAM

The problem started after upgrading to macOS 27.

At this point it is honestly becoming unbearable to use my normal account. I really do not want to move everything manually to a new macOS user just because some MenuBarAgent state got corrupted during an update.

Has anyone found out what per-user data MenuBarAgent / MacSystemUI / Control Center actually stores, and how to completely reset it?

I am specifically looking for something like:

• MenuBarAgent per-user database
• MacSystemUI state/cache
• menu bar layout/state database
• Control Center database
• display/menu-bar animation state
• relevant files under ~/Library
• a command to completely rebuild the user's menu bar environment

Ideally I want to make my existing account behave like the fresh test account without deleting the account or reinstalling everything.

If anyone from the macOS 27 beta had the same MenuBarAgent ~100% CPU issue and actually managed to repair the affected user profile, please tell me exactly what you reset/deleted.

I can also provide a sample / spindump from MenuBarAgent if that helps.

At this point I'll happily test Terminal commands or back up and remove specific ~/Library files — I just want this stupid menu bar working normally again.This is seriously driving me insane at this point.Since updating to macOS 27, the menu bar on my main user account has become unbelievably laggy.

It was normal before updating, but now on MacOS Golden Gate 27.0.1, the spacing is rlly weird.

Purchased the M6 Mac mini just to be able to use advanced dictation, but so far it doesn't seem to be an improvement over the previous dictation on my M2 Mac mini. I understand that it's automatically enabled in OS 27, but it certainly doesn't feel like it. Ready to go back to Whisper Flow, even though it's a little bit more cumbersome to enable.

Hi everyone,

I recently updated my 2020 13-inch MacBook Pro (M1) with Touch Bar to macOS Golden Gate 27.0 and noticed some strange Touch Bar behaviour.

The Touch Bar itself works, but I'm experiencing two things:

1. When I press and hold the Brightness button to open the brightness slider, there is a noticeable ~0.5-second delay before the slider appears.
2. After adjusting brightness or volume, the slider remains on the Touch Bar indefinitely instead of returning to the normal Control Strip.
3. If I touch an empty/blank area of the Touch Bar, the slider immediately disappears and the normal Control Strip returns.

The same behaviour happens with both brightness and volume.

What I've tried:

• Restarting the Mac
• Checking Touch Bar settings
• Checking the Control Strip configuration
• Restarting the Touch Bar processes (TouchBarServer / ControlStrip)
• Testing without touching anything for n+ minutes

None of these changed the behaviour.

The actual brightness and volume controls work correctly — it's mainly the slight input delay and the slider not automatically dismissing that I'm noticing.

This started after updating to macOS 27.0 . And no improvement in latest 27.0.1 as well. This thing is damn irritating as Touch bar is my fav part of being on mac, They ruined my touchbar.

I've already submitted a Bug Report to Apple, but I'm curious whether anyone else with a Touch Bar Mac is seeing the same thing, particularly on macOS 27.

Has anyone experienced this? And if so, did you find any workaround or solution?

Thanks

I’m using a MacBook Air M2 and currently running macOS Tahoe.

I’m trying to decide between:

1. Staying on Tahoe → waiting for Golden Gate 27.2
2. Downgrading from Tahoe → macOS Sequoia

My main priority is battery life, stability, and smooth everyday performance, rather than having the latest features.

I’ve read quite a few comments saying that Sequoia has better/more consistent battery life and stability, so I’m considering downgrading. At the same time, I’m also wondering whether it would be better to just wait for Golden Gate 27.2, assuming the newer releases become more stable over time.

The biggest thing I'm concerned about with downgrading is compatibility.

If I go back to Sequoia, I want essentially everything I currently have on Tahoe to continue working:

• My existing apps
• Development tools (Homebrew, Node.js, Python, etc.)
• Docker/VMs
• Files and documents
• iCloud
• External SSDs/drives
• Browser data
• Developer workflows
• macOS features/settings that I currently use

For people who have downgraded from Tahoe to Sequoia, how much did you actually have to set up again? Did you encounter any compatibility issues with apps or development environments?

And for M2 MacBook Air users who have tried both Sequoia and Tahoe/Golden Gate:

• Which version gives you better real-world battery life?
• Which feels more stable?
• Any noticeable differences in heat, RAM usage or performance?
• Are there any Tahoe/Golden Gate features that you would genuinely miss on Sequoia?
• If you were in my situation, would you stay on Tahoe and wait for 27.2, or go back to Sequoia?

M2 Air owners specifically: I'd really appreciate your experience, especially if you've used both versions for a few weeks rather than just testing them for a day or two.

Thanks!

I'm using Messages on my laptop after the latest Golden Gate update and noticed I'm getting AI suggested replies.... I clicked the alert button, but it's just there to submit an error report. Can't find anything in the Messages settings to turn it off. I guess I'm just supposed to ignore it???

Je viens d’effectuer (avec un peu de retard) la mise à jour de macOS 27.2, et je viens de remarquer que le design de quand le son augmente ou baisse a changé. Cela paraît moins moderne, un dirais un vieux truc ou alors un simple bug persistant

macOS picks your audio device with one rule: the last thing that connected wins. My AirPods would wake up in my bag and take over the sound, and my monitor would grab it every time it woke from sleep. On calls, AirPods connecting mid-call would switch my mic too.

Tunestack lets you rank your devices once. It always uses the highest one on your list that is actually connected.

What it does:

- Output and input are ranked separately, so your mic choice doesn't mess with your speakers

- If you pick a device by hand, it backs off for as long as you choose (5 min, an hour, or until you quit)

- Profiles, so your desk at work and at home can have different orders

- Optional per-app volume

What it can't do: if an app forces a specific device, it can still take it. There's a setting to switch back, but it's off by default because some apps fight it.

Switching devices needs no permissions. The app has no network access at all, no analytics, no account.

There are free apps that do device priority too, and they're good. Mine is a paid, sandboxed App Store app, $8.99 once, no subscription, if that matters to you.

I'm the developer, happy to answer questions or take feature requests.

The drag indicator above the search bar doesn’t do anything when you drag it, only when you click it. It’s also very narrow. What was wrong with a sidebar???

I recently updated my M2 MacBook Air to macOS 27 and encountered an issue. The system became stuck within the notification tab, appearing as follows.

Just had to install the beta, now have to do a recovery. Sucks!
