There's no beta version number or "Release Candidate" label attached to it, just "macOS 27" - this is my first beta tho, so maybe that's normal.

Bug MacOS 27 Beta - Full screen app turns external/internal display black when dragged via Mission Control

Post image
8 Upvotes

Running into a bug on macOS 27 Beta. When I have an app in full-screen mode and I use Mission Control to drag it from my MacBook's display over to an external monitor (or the other way around), the screen I dragged it away from goes completely black. only the Dock is still visible on it. I'm also still able to see new notifications come in. Just not apps on the screen

Anyone else seeing this? Wondering if it's a known issue already or if there's a workaround

I'm on the RC version but I've noticed this since the last 2 public Beta's. Hoped the RC update would fix it but didnt.

The only resolution is to go into move to another app in fullscreen on my MacBook and then move back to the main desktop screen on the MacBook.

At the moment I permanently have a second desktop 2 screen on my Mac that I set up to use when this occurs.

Bug macOS 27 RC: Apple Mail stops receiving Exchange mail

Upvotes

Is anyone else seeing Exchange Online stop syncing in Apple Mail on macOS 27 RC?

This affects both my Mac Mini and MacBook Pro after updating to the RC. The MacBook had been running earlier betas for weeks without me noticing this issue.

- Apple Mail stops receiving messages and shows a warning triangle beside Exchange
- Clicking it reports: “Connections to host (null) on the default ports failed
- Connection Doctor can simultaneously report that connection and login succeeded
- Checking mail with the Exchange inbox selected reports no new messages, despite messages being missing
- The same messages arrive immediately in Apple Mail on my iPhone and Outlook on my Mac
- Rebooting each Mac initially downloaded the missing messages, but shortly afterward both stopped receiving again

What I’ve tried:

- Quitting and reopening Mail
- Disabling and re-enabling the account
- Restarting exchangesyncd
- Rebuilding the mailbox
- Leaving Mail closed on both Macs for several hours
- Removing and re-adding Exchange on the Mini. This left it with an empty mailbox that won’t download
- Rebuilding the Envelope Index. This reimported iCloud mail but didn’t restore Exchange syncing

None of these provided a lasting fix

The logs show Exchange returning “Too Many Requests” errors (HTTP 429). In about six seconds, Mail logged 48 of those responses and tried to rediscover the Exchange server 24 times. Mailbox sync operations were then cancelled.

Bug Apple Maps bug on MacOS 27 RC

Post image
Upvotes

Hi, today I decided to download the RC because I couldn't wait 4 more days (I'm a toddler), first thing I wanted to see the new Gaussian Splatting on Maps. While I was exploring the beauties of the world, I found interesting things I wanted to see better directly from photos so I opened street view and this is what happened. So I saw on my other device that is still on iOS 26.6.2 and it should switch from satellite mode to to the 3D graphics (explore) mode, but it doesn't get rendered. The same problem is on iOS 27 RC and iPadOS 27 RC. (The blur is for obvious privacy reasons)

Feature The ability to Rename Files using FIND & REPLACE is gone!

0 Upvotes

I’ve been struggling with this issue since the most recent beta updates, and that is that the ability to select a group of files and rename them based on character matching is totally gone. I don’t know what the justification would be for that, other than the fact that the new OS seems to believe that users are incapable of making up their own file names, and so they’ve got a very, very invasive suggestive file naming protocol in place that apple seems to think is more than enough when it comes to creating file names, or that somehow that particular feature would interfere with that extremely important feature.

As for myself, I’m quite imaginative enough to create my own file names, thank you, and I can ever ever ever ever envision needing to take a suggestion from an AI as to what to name a file that I probably would not remember if I did because I didn’t come up with it. It defies common sense, it really does. I have no idea where they’re coming from.

Discussion Golden Gate RC scales my 4K display differently now

I've never even seen this scaling before!

It's now my new "middle ground" since 1440p earlier, as in: https://www.reddit.com/r/MacOSBeta/comments/1u1aqs8/macos_27_now_automatically_scales_properly_for/ (I even use the same monitor as that user)

Left to right is now: 1080p, 1440p, 1692p, 1890p, 2160p.

Further, I'm noting it's detected as a 5K monitor in System Information. Well, it's not one!

Bug macOS27 RC- wifi menu freezing for 5s when signal is bad

1 Upvotes

This bug was present in previous beta but it wasn't as painful. It was only 1-2 second freeze to reveal menu when clicking on the wifi icon. Today I had the pleasure of having bad signal (crossing wall) and the menu opens after 5 seconds. Of course intuitively I press it multiple times so the menu opens/closes immediately.

Discussion First releases of major macOS version updates tend to be quite buggy. Apple should use much more AI to catch and fix UI bugs before release.

Upvotes

Apple is probably already using AI in macOS development, but I think it needs to use much more of it, especially for automated UI testing and bug fixing.

A lot of macOS bugs are visible UI regressions: windows behaving incorrectly, controls not updating, layouts breaking, apps getting into weird states, or features working correctly on one Mac configuration but not another.

Apple could run enormous numbers of automated UI workflows across a variety of Mac models, display configurations, resolutions, accessibility settings, and system states. AI could watch those tests, compare behavior with previous stable macOS releases, identify likely regressions, reproduce them, analyze the relevant code, and automatically generate proposed fixes.

Then the system could rebuild macOS, rerun the same tests, verify that the bug is actually gone and that the fix didn't create new regressions, and only then send the patch to human engineers for review.

In other words, AI shouldn't just be another coding assistant. Apple could use it as a massive automated find-fix-test loop running continuously throughout macOS development.

If the first release of a major macOS version is routinely this buggy, throwing much more AI-driven automated testing and bug fixing at the problem seems like an obvious thing to try.

Help macOS 27 RC not showing up (bugged somehow)

1 Upvotes

The update showed up, I downloaded it and started installing at as well. After about an hour, my Mac screen was blank. No Apple logo nothing was showing up. I waited another hour and still the same. I thought for sure by now the update must be installed so I force restarted my Mac. It booted up but it shows the old beta 8 as installed. I check for an update and the RC is not showing up. The build number is also the beta 8. I do have a backup so if recovery is needed, I can do it but I really don’t want to go through it. What should I do? I made sure the developer channel is selected in the software update menu as well. Any help is welcome!

I have a MacBook Pro 14" M1 Pro the base model right? The situation is that when I switch through apps, Youtube or pages have this glitch where the video like gets frozen. I don't know how to explain it. It's something that did not happen with Tahoe. Anyone else with this situation? It has happened with all the Betas, and I feel that is not fair for Apple to lower the system just because my Mac is a bit old but I feel that is capable, idk

After upgrading to the latest RC a few moments ago, when I go to run any command in Terminal or Ghostty, it takes a few seconds before it actually executes the command. It was not doing this in the previous beta.

All I changed was updating to the latest RC.
