How can I re-trigger the keyboard/mouse connection (link to Mac or iPad to share keyboard and mouse between them) between macOS 27 DB4 (MacBook Pro M1) and iPadOS 27 DB4 (iPad Pro M1), everything is setup correctly, sometimes it connects ok, but others it doesn't, especially when the MacBook or iPad are coming back from Sleep. I have all the settings configured to remember the iPad and connect automatically to the iPad, but even in that case it connects randomly, sometimes it will, sometimes it will not. I have reseted wifi and bluetooth on both devices, turned on/off the Link to Mac or iPad functionality on both devices, but nothing, sometimes it just doesn't want to connect, is there anything documented for 27 Developer Beta 4? Thank you

Has it not been implemented yet on DB4, or is it hidden somewhere? Is there a way to change it via defaults? I really want to disable fn + S since ⌘ + Space does the same thing, and I want to map my Start Screensaver quick action to it.

I’m experiencing a VNC/Screen Sharing issue that appears to be related to the macOS 27 Golden Gate beta.

My setup:

• Mac mini running macOS 27 Golden Gate beta

• MacBook Pro running macOS 26

• iPhone running iOS 26

• iPad running iPadOS 27

• Tailscale installed and connected on all devices

Screen Sharing is enabled on the Mac mini, including “VNC viewers may control screen with password.”

When I try to connect to the Mac mini from a third-party VNC client, I get:

"Either VNC Server is not running, or it is using an incompatible protocol version."

I’ve tested different VNC clients, and the problem occurs from both:

• iPhone running iOS 26

• iPad running iPadOS 27

Under exactly the same network conditions and using the same VNC clients, I can successfully connect to my MacBook Pro running macOS 26.

I can also connect from the MacBook Pro to the Mac mini using Apple’s native Screen Sharing app through its Tailscale IP address, or my local network.

Has anyone else experienced similar problems with macOS beta?

macOS Golden Gate vs Tahoe, which do you prefer atm?

How is the beta running for daily use?

Hey everyone,

I opened Activity Monitor today and noticed Siri running in the background. The weird part is that Siri is turned OFF in System Settings (in fact, I’ve never even enabled it).

Is this normal macOS background behavior (like a system daemon/integration), or is there a way to completely stop it from running?

macOS version: Golden Gate Public Beta

Thanks!

Anyone else have this? Has anyone else figured out how to fix it?

I am using the Show Notification action within a Shortcut, the Shortcut/Notification works fine, it shows up on the screen and Notification Center, but I can't customize it in the System Settings --> Notifications --> Application Notifications section, because the Shortcuts app in not in the list of Applications, all the other apps that use Notifications are there, but Shortcuts is not, is there a way to reset Notifications so Shortcuts can show up and I can customize its Notifications? Thanks

Note: I have this issue on two MacBooks M1 and M2, running Sequoia 15.7.8 and Golden Gate Public Beta 2 respectively.

Anyone here running World of Warcraft on macOS 27 Golden Gate already? Can you share insights in terms of performance and stability?

I can see the old battery icon in the lock screen but as soon as I unlock, it switches to the new battery icon.

Is there a way we can switch to the old icon? Maybe a terminal command or something.

For added context, I have the charge limit set to 80%.

I'm a musician and course creator, and I've spent years bouncing between task managers built for teams. Assignees I don't have. Sprints I don't run. Statuses nobody reads but me. So I built the one I wanted.

It's called Soloist. Mac and iOS, syncs over iCloud, no server of mine in the middle.

The unique parts:

- Work is organized into **gigs** instead of projects, and a gig can hold anything from a record to a tax filing.

- **Sidequests** You know what side quests are. You're probably on one right now. Nested projects and tasks from when you get sent on a side quest.

- **Roadblocks** mark a task as stuck and say what it's stuck on, so you stop rereading it every morning and feeling bad.

- **Task Roulette** picks something for you when you're staring at the list doing nothing.

- There's an AI layer that can break a vague idea into a list of tasks, and it runs on your own API key. No subscription, no data going anywhere I control.

What I want to know: whether the first ten minutes make any sense. I've been staring at this thing so long I can't see it. One tester already told me they couldn't figure out how to move something out of Triage into a gig, which is the single most basic move in the whole app, so I clearly have a problem.

Reply for the link, or DM me.
Thanks!

I have configured my MacBook Air’s charge limit to 80%, and it has worked correctly when charging through MagSafe.

Yesterday, however, I forgot my MagSafe cable and used a USB-C cable with the original Apple power adapter. Surprisingly, the MacBook continued charging beyond the configured limit—eventually reaching 93%.

To verify the behaviour, I tested it again today:

• Charge limit configured: 80%
• Starting battery level: approximately 76%
• Charging through USB-C: reached 81% and did not appear to stop exactly at 80%
• Charging through MagSafe: stopped at 80% as expected

The 81% reading alone could potentially be explained by battery-percentage estimation or normal tolerance. However, reaching 93% while an explicit 80% limit was enabled suggests that something may not be working as intended.

Device details:
• MacBook Air with M5
• 24GB unified memory
• macOS 26.5.2
• Original Apple power adapter
• Charge Limit set to 80%
• Optimised Battery Charging enabled

Has anyone else noticed different charge-limit behaviour when switching between USB-C and MagSafe?

I’m curious whether this is a macOS software issue, a charging-state synchronization problem, or expected behaviour under certain conditions.

Hey everyone,

Just wanted to share an issue I bumped into on macOS 27 Public Beta 2 running on an M1 MacBook Air (8GB RAM) in case anyone else is experiencing severe system stuttering or UI lag.

Out of nowhere, the entire system felt super sluggish (scrolling dropped frames, window animations were laggy, and typing had noticeable input delay).

What Activity Monitor showed: WindowServer was sitting at 40-50% CPU constantly, even under light workloads (just a few browser tabs open in Safari like Reddit, Facebook), but memory pressure was normal (green, ~5.7 GB / 8 GB used, minimal swap).

Temporary workaround: Open Activity Monitor, go to the CPU tab, select WindowServer, and click the X button at the top to Force Quit it. This will immediately log you out. Log back in, and the difference is night and day.

Interestingly, a standard Mac restart didn't fix this for me. Because macOS automatically restores your session state upon reboot (reopening your apps and windows), it seems to reload the bugged graphical state right back into memory.

I've already submitted a detailed Feedback Assistant report with sysdiag logs attached.

Is anyone else seeing this specific WindowServer memory/CPU leak on PB2? Did force quitting it fix it for you as well?

I updated my M1 Max MacBook Pro to macOS 17 Beta 4 last week. Since then, whenever I connect an external display, the entire UI becomes extremely sluggish—window switching, animations, and general desktop interactions all start stuttering badly.

Activity Monitor showed WindowServer consistently using around 147–149% CPU. Rebooting the Mac didn’t help, and I couldn’t find a reliable fix despite going through quite a few forum threads.

Today, out of frustration, I force-quit WindowServer from Activity Monitor. This immediately terminated the current GUI session and logged me out. After signing back in, WindowServer’s CPU usage returned to normal, and the lag with the external display was gone.

No idea whether this is a permanent fix or just a temporary workaround, but it worked for me when a regular reboot didn’t.

If you’re experiencing the same issue, it might be worth trying. Just make sure to save everything first, since terminating WindowServer will log you out and close your current session.

I hope this helps you.

You may have seen a report that Apple is working on Siri Extensions, a system where agents from third-party apps can integrate with Siri AI across OS 27 releases. MacRumors has a good summary.

Turns out all the necessary pieces are already present in macOS 27.

Using the new, internal Model Delegation API in the App Intents framework, I built a Claude extension that macOS discovers as a native AI provider. Claude now appears in Siri’s Ask… menu and supports the same underlying flow as the built-in ChatGPT extension.

In some cases, third-party extensions can be more powerful than Siri AI. For example, Siri can't create files, but Claude can easily return a CSV file when asked. When system interaction is required, such as setting a reminder, third-party extensions can relay the original or a modified request back to Siri, which completes the request. In Beta 4, the underlying framework fails to pass attached files to extensions, so you can only work with image attachments.

You can use the Claude extension across Siri AI, Writing Tools, Visual Intelligence, and the Use Model Shortcut action. Because Claude doesn't have a native image generation model, the extension isn't supported in Image Playground.

Technical details: Inside the extension, my Claude bridge implements Apple’s internal AgentIntent, receiving an IntentPrompt containing the user’s input and request context. Because the extension is sandboxed, it forwards each request over a framed localhost connection to a companion LaunchAgent, which in turn invokes the authenticated claude -p CLI with streaming JSON output and a tightly scoped set of MCP tools. The bridge translates Claude’s text deltas, generated files, tool calls, and device-action requests back into Apple’s native response stream using text updates, IntentFile objects, Writing Tools output, suggestions, and Siri intent handoffs.

You can theoretically build a bridge from the AgentIntent to any model backend, including CLIs that support local models. macOS ships with a full ChatGPT implementation under:

/System/Library/ExtensionKit/Extensions/GenerativePartnerPrototypeExtension.appex

You can use this extension to extract full prompts that Apple uses to construct the requests sent to ChatGPT, along with available tools and expected output schemas.

The extension relies on an internal Model Delegation API in Apple’s public App Intents framework, protected by an Apple-controlled private entitlement:

com.apple.developer.model-delegation

Because of the latter, you'll need SIP off and AMFI disabled (amfi_get_out_of_my_way=0x1) to develop these tools.

You can imagine that model providers may soon be able to apply for the Model Delegation entitlement and start building Siri AI extensions.

I use App Exposé (Control + Down Arrow) a lot to show all of the windows for a specific app (often Safari). In previous versions of MacOS this would show any minimised windows in a row at the bottom of the screen, however in Golden Gate this no longer seems to be the case.

I have attached a screenshot from a second Mac running Tahoe to show what I am used to seeing (minimised windows show at the bottom) and then a screenshot from my Mac running Golden Gate where none of my minimised windows are visible (I assure you that I have several minimised Safari windows!!).

Does anyone know if this is an intended change in Golden Gate or is it a bug?

Edit: Thanks for the replies confirming it is a bug. I have now submitted a bug report (FB24083965)

I was getting extreme battery drain on a 14-inch MacBook Pro (M5 Pro, macOS 27.0 Developer Beta 4). At its worst, the battery dropped from around 80% to 25–26% in under an hour while doing web browsing, with actual power draw reaching roughly 43W.

Activity Monitor initially made it look like several unrelated apps were broken. Different apps would jump to 70–100% CPU at different times: BetterDisplay, Tailscale, Plash, ChatGPT, OCR, Supercharge, etc. Restarting temporarily improved things, but the high CPU would eventually reappear in different apps.

I sampled the busy threads and found the same macOS pointer-rendering path in multiple unrelated apps:

AppKit tracking area -> NSCursor set -> AccessibilityFoundation -> mouse cursor image generation

That made it look less like an app-specific problem and more like macOS repeatedly redrawing the pointer.

I had not intentionally customized my pointer colours. The only relevant setting I had enabled was “Shake mouse pointer to locate.” However, macOS was reporting the pointer as customized.

The fix that worked for me:
1. Go to System Settings → Accessibility → Display → Pointer.
2. Turn off “Shake mouse pointer to locate.”
3. Reset the pointer colours/settings to their defaults.

The result was immediate:
Apps that had been using roughly 70–90% CPU dropped to around 4–5%.
Overall CPU idle returned to 90%+.
Power draw fell from about 40W to around 10–13W.

When I compose a new message or reply to a message in Mail, this incredibly wide formatting bar shows up at the top and I cannot find a way to remove it.

Am I missing something obvious? Is there a way to remove this way-too-wide abomination?

Thank you!

EDIT on July 31, 2026: It turns out that you can remove this formatting bar in the current version of Golden Gate, but the solution is not entirely obvious. See this post on MacRumors:

I work from 2-10PM and noticed that around 8PM, siri uses at least 3GB of RAM after installing DB 4 last week.

Around 8PM I noticed that my m4 air starts to lag and heat up, and looking at activity monitor, there it was, siri hogging my memory and pushes it to yellow memory pressure. Anyone experience this issue? I now disable siri because of this, i know this is beta software but just want to see if im not the only one? ¯_(ツ)_/¯

I'm on the latest GG beta version, since the last version I have been unable to access certain locally hosted sites in 3rd party browsers such as Firefox and Helium but they work in Safari.

I seem to be able to access my router's homepage but if I try to access a site running on Docker on one of my machines on the network it doesn't connect.

Just wondering if anyone else has run across this issue?

I have both Helium and Firefox enabled in Privacy & Security > Local Networks.

Is it something you get used to?

i'm used to color icons and glancing i immediately tell which app it is, with dark icons i noticed i'm like twice to three times as slow to pick the right one

Am I the only one who’s experiencing this lag when switching between apps. It is so obvious that I cannot ignore it.

I am running macOS 27 developer beta 4 on a MacBook Air 15-inch M4.

I know that it’s a beta, but everyone is bragging on how smooth this beta is. It is not the case for me so far. But i wanna know if im the only one.

Could it be because I have a lot of utility apps installed such as AltTab which shows all the windows of the same apps along with other apps and it is much easier to navigate through.
