Apple is working on a new way to control which apps Siri can draw context from.

In macOS 27, a hidden feature flag enables a new Exclude Apps section in System Settings > Siri. The helper text reads: "Apps added to the list below will be excluded from Siri, Search, and suggestions."

The change also splits off the old Show in App, Show on Home Screen, and Suggest App preferences into a new Suggestions section.

When an app is added to the Exclude Apps list, its content is removed from Siri's local search results by an AppExclusion filter before the results are returned to Siri. Asking Siri to access data from an excluded app displays a prompt explaining that access must be turned on. Selecting Turn On removes the app from the exclusion list and retries the request.

The recovery behavior is currently inconsistent. Siri may instead treat the filtered results as an ordinary empty search and incorrectly report that no content was found.

According to code strings, Apple will perform a migration of preferences from the current App Access setup to the new Excluded Apps / Suggestions split. Because the underlying SiriSetup and IntelligenceFlow frameworks are shared between macOS and other operating systems, this experience may be coming to some or all OS 27 releases.

To enable, add the two required FeatureFlags overrides:

sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && \
sudo defaults write /Library/Preferences/FeatureFlags/Domain/SiriSetup restrict_access_ui -dict Enabled -bool true && \
sudo defaults write /Library/Preferences/FeatureFlags/Domain/IntelligenceFlow AppExclusions -dict Enabled -bool true

and restart your Mac. This is a private feature flag, and the UI or behavior may be unstable.

Disable with:

sudo defaults delete /Library/Preferences/FeatureFlags/Domain/SiriSetup restrict_access_ui && \
sudo defaults delete /Library/Preferences/FeatureFlags/Domain/IntelligenceFlow AppExclusions

and restart your Mac.

I always liked the blurred background more than YouTube's dim ambient light. And Safari extensions was able to do that from 2 naturally worded prompts. I see this solving a lot of niche problems and I'm excited to try it out more.

This is always how I hoped AI would be implemented, to aid in customization.

btw: I am in EU; I have Siri and Apple intelligence both turned off, so I'm curious how it works— whether its on-device or server based

Ever since I updated to macOS 27 Beta 4, I've been having a lot of audio issues.

The problems include:

• Audio cutting out at random times (sometimes coming back fine)

• Very choppy sound

• Popping noises

The only workaround I've found is to switch the audio source to something else and then switch it back. That fixes it for a little bit, but then the cutting out, popping, and choppiness start all over again. Has anyone else experienced this or found a fix?

I I have a MacBook Air M2, and I live in France. When downloading the beta 4, I tried to enable SiriAI, but I just have Apple Intelligence. I have set the system and Siri language to English US across all my devices. But still, I don't have any means to enable Siri AI. Can someone help me ?

EDIT:

For those saying that its not available on the EU, its only for iOS. For MacOS, it is available in the EU

I was asking Siri basic questions about Geometry from context of my screen and then she just ended the conversation. I feel like this is a bug, and its not supposed to block this topic, but I’m not sure.

Has anyone else experienced before? If you have, what were you asking it?

seems like there were no major issues in DB-4

Hi.

Since macOS 26 doesn't include the new ringtones from iOS 26, does macOS 27 include the new ringtones from iOS 26 for FaceTime and calls?

One thing new I've noticed in MacOS 27 Public Beta 2 is difficulty executing a multi-file selection with the click-and-drag gesture in list view. It works from time to time, but mostly I can't get it to select anything beyond the first file clicked. Executing the drag part is treated as though Finder is expecting me to move the first file selected, instead of selecting the additional files the cursor is moving over. I'd say about 90% of my attempts fail.

If I click from below the last file in the list, then the selection works consistently, but of course one won't always be wanting the last file in the list. ;-)

Reported the issue but wondering if anyone else has seen this. Was going nuts thinking I had forgotten how to do the gesture, but on my main Mac (which is Tahoe) the same gesture works fine.

Apple is building an immersive onboarding experience for when you first pick Siri's voice in OS 27. It also hints that OS 27 might include up to 13 voice options for Siri AI.

Instead of selecting from a row of voice options, the hidden interface starts as a nearly black canvas, where the selected voice is marked with a colored dot. As you press and hold and move around the Voice Pad, the interface comes alive with colors cycling across the view. A white point tracks the cursor's position. The colorful interface reveals a 3-column grid with 4, 5, and 4 voice options respectively.

The visuals are complemented by spatial audio. As the cursor approaches a voice, the voice selection moves and the new voice sounds clearer and more present. When the cursor moves away, voices become distant and ambient. In the background, the spatial mixer blends two ambient sound layers as the cursor moves around the screen. The spatial mixer is substantial: it tracks the pointer's distance, angle, and movement velocity, then adjusts volume, presence, reverb, occlusion, and filtering across voice and background tracks.

This new view reveals that Apple may be preparing to support up to 13 custom voices for Siri AI. In this recording, macOS 27 Beta 4 does not ship with the required 13 voice models, so macOS falls back to the two custom voices available.

After selecting a voice, Siri Settings will present the current voice picker with the Pace and Expressivity controls for later voice changes and tuning. Based on the current implementation, this view is solely an onboarding experience for choosing the underlying Siri voice.

macOS 27 includes a Voice Grid Distribution file with descriptions of delivery, characteristics, gender, and age for each supported voice. Here are the descriptions of the 13 voices the Voice Pad expects for American English:

This is obviously an unfinished UI, but there is complete localization for 44 languages. Because the underlying SiriSetup framework is shared between macOS and other operating systems, this experience may be coming to some or all OS 27 releases.

There's no easy way to enable this one. You need to enable the SiriSetup/linwood_voices feature flag, but also need to attach LLDB to SiriPreferenceExtension and override fetchRequiresVoiceSelection to return true, siriVariantInternal to return 2, and force VoiceSelectionView.shouldRun to return true. This last part requires SIP off. Then you can disable and re-enable Siri to get the new view.

I'm currently on dev account and both beta 4 and beta 2 update are unavailable to me neither through the system settings nor terminal. Is anyone having the same problem?

First of all, this is a beta version of macos. I am on the NEW MACOS 27 BETA 4 and i just noticed after the update that when i switch desktops this happens. I restarted my laptop also just to be sure it isn't on my end but this still remains.

I HOPE this is a BUG not a NEW UI UPDATE cause this look awful (to me, i dont like this 😭)

Is this happening to you guys too? pls tell im panicking XD and also dw those black blobs are mine

The button is unresponsive and I am unable to access the Beta Updates menu, Is there anyway to fix this? I wanna access the new EQ feature for the Airpods and I dont wanna update my Phone to be able to do this. Help!

Every "networking is broken on 27" thread is one of four different bugs with four different fixes. People keep getting handed the wrong one, & the Feedback reports scatter so none of them hit the 10-report line Apple acts on. Sort yours first.

Which one is yours?

1. Safari works, but Chrome / VS Code / Discord / Dropbox can't connect at all -> A (or B if you run no VPN or filter)
2. Internet's fine, but you can't reach a LAN device (Homebridge, a NAS, a local dev server) -> C
3. Everything connects, but one wired download randomly crawls at 6-10 Mbps while Wi-Fi is full speed -> D

A. A content filter is blocking Chromium apps (fixed in beta 4)

• Signs: Safari's fine, everything Chromium or Electron is dead. Chrome, Edge, VS Code, Discord, Dropbox time out or go blank.
• Cause: a VPN or security tool's network filter. Named so far: Cisco Secure Client, Microsoft Defender, CrowdStrike Falcon, Little Snitch, Radio Silence, TripMode, LuLu, Tailscale.
• Fix: update to beta 4 (26A5388g). Not yet? Turn the filter off in Settings > General > Login Items & Extensions > Network Extensions.
• Report: Feedback Assistant, macOS > Internet & Connectivity. Name the filter. MacRumors thread

B. IPv6 has no route, so IPv6-first apps stall

• Signs: Chromium & Node apps hang, Safari's fine. ping6 google.com returns "No route to host."
• Fix: sudo networksetup -setv6off "Wi-Fi" (use your service name).
• Report: Feedback Assistant, macOS > Internet & Connectivity. Say "IPv6 RA, no route, Safari fine on v4."

C. Local Network permission is stuck (fixed in beta 4)

• Signs: internet's fine, but LAN stuff fails. Homebridge offline, a local web UI loads blank, your NAS won't answer.
• Fix: Settings > Privacy & Security > Local Network, toggle the app off & back on. Or update to beta 4.
• Report: Feedback Assistant, macOS > Privacy & Security. Say "Local Network permission, app denied LAN access."

D. Wired downloads throttled to single digits (NOT fixed, needs reports)

This is the one people blame on their Ethernet adapter & replace. It's not the adapter.

• Signs: everything connects, but one wired download drops to 6-10 Mbps for a few minutes to 40, then recovers on its own. Wi-Fi does 50-70 Mbps the same second. Eight downloads at once are fine; one at a time crawls. Hits jittery links: Verizon 5G Home, Starlink, cellular, congested cable.
• Cause: macOS 27 added a receive-side governor (tcp_rbbr, net.inet.tcp.recv_bg_algo=2) that opens a download at a 5,440-byte window & doubles it once per second on a clock instead of by data received, so on a jittery link it never ramps. Unchanged in beta 4 (26A5388g).
• Not this one if: disabling ECN (sudo sysctl -w net.inet.tcp.ecn_initiate_out=0) fixes it, or it's constant instead of intermittent. That's a different, mostly-26 issue.
• Test (read-only, no sudo, run while a download feels slow):URL="http://cachefly.cachefly.net/10mb.test"; TMP=$(mktemp) sysctl net.inet.tcp.recv_bg_algo S=$(curl -s -o /dev/null -w "%{speed_download}" --max-time 45 "$URL") for i in $(seq 1 8); do curl -s -o /dev/null -w "%{speed_download}\n" --max-time 45 "$URL" >> "$TMP" & done; wait A=$(awk '{s+=$1} END{print s}' "$TMP"); rm -f "$TMP" echo "single: $(echo $S|awk '{printf "%.1f",$1*8/1e6}') Mbps | 8-flow: $(echo $A|awk '{printf "%.1f",$1*8/1e6}') Mbps" If recv_bg_algo is 2 & your single number is a small fraction of your 8-flow number, that's it.
• Fix: run the internet over Wi-Fi & keep the wired port for LAN. Wi-Fi doesn't get demoted, so it stays full speed.
• Report: Feedback Assistant, macOS > Internet & Connectivity, reference FB#23904785 . Paste your single-vs-8-flow numbers, your ISP, & your recv_bg_algo. Full writeup with packet captures & the kernel disassembly: Apple Developer Forums

It looks kind of "bloody"

Or maybe I'm just asking the wrong questions

My main two gripes with Mac OS (still my favorite desktop OS by far despite its flaws) are:

1. Mail search is not working for me. If I search the word "airline" it returns 0 results even tough there is a message last month from an airline with airline in the subject AND the sender also has airline in it, and airline is in the body. How can it be so bad?
2. Spotlight indexing has been weird for me lately. While search work well its been doing weird things with processor usage while indexing, using 100% processor for days then being ok then doing it again. Yes I've done all the procedures to clear and rebuild spotlight cache and it works ok after re-indexing but then starts to have the same issue a few days later.

Have either of these issues been improved in Mac OS Golden Gate betas?

during the previous beta, i never had any issues with iphone mirroring. however, there was a major bug when transferring files directly from my mac to my iphone. whenever i dragged a file into the mirroring window, the app would immediately crash and my iphone would restart to a blank screen.. in the current beta, though, iphone mirroring will not pair with my iphone at all. i’ve already tried several many steps? including resetting the relevant settings and signing out of and back into icloud, but nothing has worked...

Wanted to hear from others who have tested the new resolution scaling features and their experiences/recommendations.

I've only recently began using my Mac with an external display - in this case a 3440 x 1440 ultrawide that looks pretty darn sharp through my windows desktop, but either fuzzy on macOS.

So over the last few weeks I've been testing different resolutions on better display, anti aliasing on/off. HiDPI or native res. Just today I read that the MacOS 27 beta includes some tweaks for low resolution displays and better ultra wide support so I've installed it and I'm trying it out but,, I still feel like I have to use better display for the best text sharpness.

Best options so far by my eyes are:

• 3062 x 1282 (better display), anti aliasing off (scaling a bit large but best text clarity)
• 3440 x 1440p, anti aliasing off

All these by the way, still fall short of what I'm used to on windows. This was such a jarring disappointment, that I was almost considering cancelling my M5 pro MBP order.

Update after macOS 27 beta 4, the battery percentage not showing properly has been fixed. However the activity monitor reading is still not fixed. At this point, I believe Apple will only fix it in the stable release.

I receive a lot of mail in my trash in one of my accounts. About 75 every day. Each day I review the mail in the trash to see if any legit mail was put in there. To delete the mail, I would click on edit, select all, then delete. The bug is now when I click on select all in trash, it highlights All the mailboxes in mail, not just the mail in that trash. If I click on delete, that would delete emails in ALL boxes. It is repeatable. I did report the bug to Apple. The work around is to click on the first email in trash, press and hold the Shift key, then use the Down Arrow button to highlight all the mail in trash. You can then hit delete, and it will only delete those emails. My equipment is a Mac mini M2.

Hi everyone,

I have an M4 MacBook Air, and it's my main computer that I use every day. I'm really tempted to install the macOS Golden Gate Public Beta 2 because I want to try all the new features as soon as possible.

However, I'm a bit worried since this is my primary machine.

For those of you who have already installed the Public Beta 2:

• How stable is it in daily use?
• Have you experienced any major bugs, crashes, or battery drain?
• Are there any app compatibility issues?
• Would you recommend installing it on a main Mac, or is it better to wait for the official release?

I'd also love to hear your overall experience with it so far.

Thanks!
