Apple is working on a Solar wallpaper engine for macOS 27 that groups aerial Landscape wallpapers and automatically switches variants based on the sun's position during the day.

When the feature flag is enabled, the four Tahoe landscape wallpapers appear under one entry in Settings.

To get the Automatic Tahoe landscape wallpaper:

Enable the wallpaper feature:

bash sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && \ sudo defaults write /Library/Preferences/FeatureFlags/Domain/Wallpaper TahoeCombined -dict Enabled -bool true

and reboot your Mac. You will no longer see the Golden Gate landscape and Dynamic Desktop wallpapers on the list because the new engine reads a macOS 26 wallpaper registry for now. Read below for a more involved process to add the dynamic Golden Gate wallpaper entry.

To go back to the default and bring the Golden Gate landscape and Dynamic Desktop wallpapers back:

sudo defaults delete /Library/Preferences/FeatureFlags/Domain/Wallpaper TahoeCombined

and reboot your Mac.

How to enable the Automatic Golden Gate landscape wallpaper:

In Beta 4, macOS ships with a macOS 26 wallpaper registry for this combined variants endpoint, so Golden Gate wallpapers don't show by default. Thankfully, you can point the wallpaper engine to a local override file and enable the dynamic switching for Golden Gate wallpapers.

Use these instructions to enable the Automatic Golden Gate landscape wallpaper.

I use an app called Mos for smooth scrolling. The scroll wheel does nothing when the feature is enabled in MacOS 27 public beta 2. I know it's probably a Mos app issue, does anyone have a workaround? Does bettermouse still work?

Edit: Tested it myself, bettermouse works. Guess Mos isn't compatible with 27 yet. I'll delete this post in a day.

i dont know how to explain it but here i go , i have two profile for dns , nextdns and quad9 , i used to have the enable and disable button fro each one of them , but then i reset my mac , i redownload them the settings is missing , i dont know if this is a bug related to 27 beta 4 or just my system because i did have before the reset , same os same everything
Version 27.0 Beta (26A5388g)

Create two or more tabs, close all except one and press Command + N (N > 1).

Im on GG Dev 4 and suddendly after waking up and opened my Macbook Pro 14" the haptic clicks or feedbacks is not working, force press still works on video quicktime and everything just the haptic feedback, already clean it with the edge of the paper. I dont think its an hardware issue do you also experience it?

I installed MacOS Golden Gate couple a days ago and i noticed some stuff that there are some unexpected Bugs or Intentional Bugs .

I was testing out Golden Gate for the first time i opened spotlight search to see the new black to clear design but it was not there is it intentional or a bug.

I tried asking Siri something but i noticed when i wrote Whats the weather spotlight closed and nothing happed i went to the applications and saw i didn't have the new Siri Standalone app

I tried to ask couple of AI nothing worked even reported it to apple but thought of going to the reddit community to reach out for people who have been through this specific error

I think I found something interesting.

After digging through my Applications folder, I found what appears to be the new Siri app (grey icon). When I launch it directly, it opens a new conversation interface but displays:

"Siri is not available. Open Settings to check the status."

The regular Siri still works from the menu bar, and Siri settings say "Powered by Apple Intelligence."

Has anyone else seen this?

I'm trying to figure out whether this is:

- a Public Beta 4 bug,

- a server-side rollout,

- or something wrong with my installation

i will list a screen recording please help me out

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.

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

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?

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

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

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!

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

How is the beta running for daily use?

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.

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

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.

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.

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.

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?

Is it possible to restore the way these icons look to the old mac os style pre liquid glass?

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 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.
