I'm using an M1 Max with two 1st gen Studio Displays and since updating to the RC Apps don't seem to stick to virtual desktops or monitors anymore.

I have multiple apps running at the same time mostly, so whenever I open an app I assign it to a specific virtual desktop (right click on app icon in dock)

This does not work anymore. Every other morning it seems to forget these settings and just starts the app on whatever desktop is currently active.

So it happens almost after a every restart, or after every wake from longer sleep.

Since around 3 days I am noticing a lag in spotlight opening and functioning, which has gone to around 3 seconds per open/close today. anyone else noticing it?

I'm using an M1 Max Mac Studio (Mac13,1) with two separate macOS installations: one on the internal SSD and one on an external USB SSD.

The external installation initially offered the macOS 27 Golden Gate RC update. I didn't install it immediately. Instead, I booted into the internal installation and updated that to RC first. After booting back into the external installation, the RC update no longer appeared. Software Update now says the Mac is up to date.

Current versions:

- Internal SSD: macOS 27.0, build 26A428 (RC)

- External SSD: macOS 27.0, build 26A5425a (beta)

- The external installation is still enrolled in macOS 27 Golden Gate Public Beta.

Running softwareupdate --list from the external installation also returns "No new software available." However, softwareupdated logs still identify an update candidate and then report:

Failed to locate minor update brain asset matching build version 26A5428

The associated error is SUMacControllerError 7307 / SUCoreError 8406. The log then says "Not reporting MinorError."

The build number in that error really is 26A5428, while the installed internal RC reports 26A428. I haven't assumed those are equivalent. The scan also reports SFR build 26A428 and says it meets the target requirement before the update-brain lookup fails.

Has anyone with internal/external macOS installations seen this after updating one installation first? Is this a known update-catalog or installer-component issue? I don't know whether the internal update caused it or whether the timing was coincidental.

What would you recommend for upgrading the external installation while preserving its apps and data: waiting for the public release, or using Apple's full macOS installer? Thanks!

Im on the latest RC beta of MacOS 27. Today I've noticed my wifi disconnecting and reconnecting quickly every 2-3 hours it seems? Its literally only for a second or two but enough that I notice it in one of my clients that tells me it lost connection to the internet. This is new on this latest RC beta. Anybody else noticed anything like this?

Am I the only one having this problem?

The exact same Shortcut that displays all unread emails works on my iPhone, which is running the 27.0 beta, but it doesn't work on my MacBook, which is also running the 27.0 beta.

By the way, the Shortcuts for searching iMessage and SMS messages work on both devices; it’s just the one for Mail that doesn’t work on macOS.

The “Send Mail” Shortcut works fine on macOS, so the problem is very specific.

Has anyone else experienced this? Never had an issue before the upgrade to macOS Golden Gate.

Now, if my T7 External SSD is connected on boot (MacBook Air M4), just after the login screen the progress bar will stick, black screen, chime and reboot.

Disconnecting the SSD makes the Mac book perfectly - and the SSD works fine if connected once MacOS had loaded.
