Safari tabs now lift and scale as you drag to reorder. When you tap and hold a tab to open its context menu, the touch menu now omits “Ask Siri.”

Didn’t we have that super clear tab style without the lift and scale in the betas over the summer when using a pointer?

Hi all,

I’m not technical at all, so apologies if I’m missing something obvious. Apple offered me the latest, fastest and richest macOS, and nothing told me it was still in beta, so I upgraded from Tahoe to GoldenGate 27.0.1. I now regret it bitterly.

Right after a restart everything is fine. A few hours later the Mac becomes sluggish:

• Apps freeze or lag
• The Dock magnification animation (the wave effect) stutters
• Everything freezes for a moment when I press Cmd+Tab
• The cursor often disappears for a few seconds

It ran smoothly on Tahoe.

My setup

• MacBook Air M4, 24 GB RAM
• About 25% storage free (377 GB used of 494 GB)
• Previous macOS: Tahoe
• Time Machine backups from before the upgrade
• Open apps: Outlook, Chrome (10 tabs), Notion (4 tabs), Claude, WhatsApp, Preview

Activity Monitor, sorted by % CPU, while the Mac is slow (screenshot attached)

1. Google Chrome Helper (Aperitif Renderer): 326.3%
2. kernel_task: 268.5% (52 h of CPU time)
3. WindowServer: 93.8%
4. OneDrive: 56.1%
5. Google Chrome Helper (Aperitif Renderer): 7.9%

Memory looks fine: about 70% used, memory pressure around 36%, 6.8 GB compressed.

My questions

1. Has anyone else seen this on 27.0.1, and is there a known cause? kernel_task and WindowServer seem very high to me.
2. Is there a simple fix a beginner can try?
3. Since I have a Time Machine backup from before the upgrade, what is the safest way to go back to Tahoe without losing recent files?
4. Does anyone know if a fix is likely in the next update?

Thanks a lot!

at least with brave I'm having trouble dragging the window around, anyone else having this issue? it's like the window is locked in place sometimes

edit: discord same issue, cant drag the title bar to move the window. Also double clicking it isn't making it change size

I have been trying to install macos Sequoia on my m1 pro MacBook pro by using a bootable installer I've created.

however, every time I try I get the message that "this copy of the install macos Sequoia application is damaged and can't be used to install macos". At first I assumed that I had a bad download of the os and redownloaded from scratch, but the issue persisted.

Then, I tried using the internal SSD as a temporary bootable volume, and got the exact same issue with a fresh download and install of the macos Sequoia installer.

I then thought that maybe it was a specific version of Sequoia I was using, so I downloaded a different one through terminal and yet again I get the same error.

Failing all else I attempted to downgrade to Monterey by also creating a bootable installer and it gives me the exact same error.

the weirdest thing about all of this is I had actually successfully downgraded in the past and everything worked completely fine, however after updating again it now seems like I'm stuck where I'm at.

The installer is damaged message seems like a generic message when the computer simply refuses the installer because after 3+ downloads of various versions of macos I highly doubt every single one was bad.

My current install is running the 27.2 dev beta 3. i have absolutely no idea what is causing these errors but if anyone has a clue or a solution please let me know.

Also fixed the transition in Mission Control from a full-screen app to an app in the dock. Enjoy!

Most annoying Mission Control bugs are now fixed by Apple in macOS 27.2 DB4 and fairly quickly, but animations still need tweaking IMO.

Notice how visually busy the Golden Gate's animation is. You get these flashes or unwanted content at the top of the screen at the end of animation, which can be distracting. In this video they are slowed down to show exactly what's happening.

Notice how Sequoia’s animation is much more focused and, in my opinion, more pleasant.

obviously irony

i clicked on the siri icon in the menu bar (which changed its position to after the control center) and this abomination showed up and is totally bugged, above all windows and doesnt go away.

Edit: the microphone button works, i clicked it and told it to go away and it disappeared

Weird one. When a video is paused in fullscreen in Safari, a normal click with my mouse doesn't resume it. If I hold the button a bit longer, or move the mouse slightly while clicking, it works. The trackpad works fine every time, and in windowed mode the mouse is fine too.

It's Safari only. Same mouse, same kind of click works in Chrome fullscreen and in the Apple TV app.

Setup: Mac mini M4, macOS 27.2 (26B5112a), Safari 27.2 (22625.2.8.11.6), Logitech MX Master 3S over Bluetooth. Works fine in Chrome 155.0.8059.80. Happens on YouTube and other sites.

What I've checked so far:

- Quit Logi Options+ and unloaded its agent, still happens

- No third-party apps intercepting input

- Logged the raw mouse events: every click arrives fine (down + up, no movement)

The interesting part is the difference in the events. Clicks that work always have a "mouse dragged" event in between, even a zero-pixel one. The trackpad always sends those, and so does a long press on the mouse. A quick, still click doesn't, and that's the one Safari ignores.

Running an iPad app (RTIPanel) used to work fine but on 27.2 it crashes. Something about tabbing, ChatGPT claims.

This is still I place in 27.1, but not the .2 beta. Is that known? Is there a workaround?

Correction: Command-Clicking... Not Control

After updating to macOS 27, the search dropdown in System Settings completely breaks out of the sidebar bounds. The menu overflows past the bottom edge of the window, making the bottom options look cut off.

I’m not sure if it is just me but I feel like performance overall has taken a massive hit on MacOS 27.2. I have a 14” MacBook Pro with M3 Pro and it has been struggling to perform tasks it has never struggled with before. Blender can’t load properly, Illustrator lags, Roblox can’t even get 60 fps at the lowest settings. Please tell me it’s not just me.

the AI stuff on 27 is spread across about a dozen settings now, some of them under screen time, and the models stay on disk anyway

so i made RemoveMacAI, it started as a cli and 1.0 is a proper app now

it goes through all of those settings for you and removes the models, and the block stays through updates since it's a configuration profile

if an update resets one of the other settings the app shows it as not applied and you can apply it again

you can keep any feature you actually use, and undo everything from the app

I fail to see any logic to it, but maybe there is one?

I upgraded from macOS Ventura (v13.x) to macOS Golden Gate recently because of a computer upgrade from an old intel Mac to an Apple Silicon Mac.

Alas, it looks like the native driver for my laser printer, Brother HL-5250DN is no longer supported on macOS Golden Gate, and instead the OS is needing to use a Generic PCL driver. I checked the Brother website, but because this laser printer (an emulation Postscript printer using Brother's own BR-Script) is from 2007, they no longer update the software for it.

The problem with the Generic PCL driver is that it doesn't know that the printer can print in 1200 dpi (or another similar dpi called HQ1200). As such, I'm investigating if there are other solutions such that the full features of this printer can be used by my computer running macOS 27.

You'll notice too that the driver is a PCL language driver rather than Postscript (or emulated Postscript), so that itself is already a limitation.

Any tips? What can I try? I'm not in the market for a new printer as we don't print as much these days. This laser printer has been with us since 2007 and still running well!
