Never pressed the button "Update" faster than today, when I updated to 27.0.1.
Sad truth is, majority of the problems with mission control are still there, if not worse. Anyone experiencing the same?

There have been many issues reported with Mission Control and Spaces on macOS 27 Golden Gate, especially regarding the way Full Screen apps and app switching are handled. Some have been resolved by identifying and removing incompatible 3rd party extensions, others are bona fide bugs. The minor point update, macOS 27.0.1, did not appear to address the more significant issues.
See if the problem is present when you boot in safe mode. That process performs some system cleanup and clears caches, and also disables 3rd party extensions that may cause problems.

Personally, Mission Control is working fine for my use cases on my 16" M4 Pro MBP running 27.0.1. I have many Spaces and open windows, but I don't use full screen apps and I don't have my apps grouped, both of which are associated with reported issues.
I did notice one fix in 27.0.1 along these lines, but only a partial fix, for App Expose (Force Click on an app icon int he Dock). In Tahoe, doing so shows active windows of that app (across all Spaces) as large Mission Control-style panes and minimized windows of that app as small thumbnails along the bottom. I presume that is the expected behavior. On 27.0, Force Clicking on a Dock app icon did nothing, and in 27.0.1 it shows the large panes for active windows of the app, but minimized still windows do not show up. Baby steps...

This update patched a security flaw involving a zero day exploit that Apple suspected was being used in the wild.
That's it. Nothing else was "fixed". We will be seeing more and more of these frequent patches because AI is being used by both the good guys and the bad guys to find flaws. Finding them and fixing them is a race with AI involved now.
The 27.0.1 sub-update stated what it was intended to fix, and there were also a number of undocumented fixes behind the scenes that Apple never documents. If you have a specific issue with Mission Control, then by all means do not assume that Apple is clairvoyant and send direct feedback to the macOS Product team. They will not read posts in these public communities…
If the issue is known by Apple, then see if it is resolved in 27.1 or 27.2 when they are released.

Consider that the macOS 27 (Golden Gate) developer beta was released on June 8, 2026, followed by the public beta on July 13, 2026, before the full software officially launched on September 14, 2026. That's three months of developer testing and two months of public testing, both across several iterative beta versions. And of course, plenty of testing internally before Apple released the first developer beta.
In general, MAJOR issues are going to be found and fixed before the full release. What is left that impacts the general public mainly falls into three categories:
By far, the majority of issues fall into that last category.

If I’m wrong, please do give your opinions.
I also think you're wrong, but for a different reason.
Tahoe has proven unstable even at later build versions. The idea that any particular .n version is going to be more stable than a .n-1 version is no longer true. Later versions can, and do, introduce new bugs. Developers simply don't do "major versions" and "bug fixes" anymore. Instead, it's a constantly rolling assembly line of changes. Some changes fix some bug, but introduce new bugs. And I want to make an important point. These new bugs often aren't surprising or unanticipated. It is standard procedure to knowingly introduce breaking changes.
And that's another important plot point. Concepts like "unstable" and "breaking" aren't binary. Just because a particular OS version works for one person does not mean it will work for everyone else. In the past, we would typically attribute these different kinds of experiences to 3rd party system modifications. That certainly still happens, but it isn't required. I have personally experienced significantly impactful bugs in Apple software that could not be attributable to 3rd party modifications, but also did not occur for other people.
As the operating system has grown increasingly complicated, these kinds of experiences are getting more and more common. There is a beta test cycle, but the bar for those releases is very low. A bug would have to impact a significant majority of all users in a significant way before it would impact the release schedule. The schedule is king - bugs, changes, user experience are all secondary.
There are always bugs in a new major macOS upgrade. Most are eventually resolved by point updates, but some point updates create new bugs. I typically update my personal Mac, iPad and iPhone immediately, and I hold off on updating my work Mac until the x.1 or x.2 update.
Personally, I've never experienced significant issues with macOS or iOS upgrades. Minor annoyances yes, but nothing that has meaningfully impacted my workflows. For example, once in a while on macOS 27.0.1 the screensaver setting will change itself from my usual selection (an album in my Photos Library) to the macOS Golden Gate screensaver. I change it back, it sticks for a day or two then switches. A minor annoyance, not meaningful to me. I reported the bug to Apple, as usual. At some point, it will be fixed.
Wait what? On your M4? Then it’s definitely software-wise and not your hardware OR my hardware, I thought it was because of my 8GB of memory on my M1 Air, I recommend you wait for at least a week after updating to golden gate so your Mac can properly index the update, when first updating, you’ll definitely notice slow downs, and battery drain as your Mac is working overtime to index the new major update, If you’ve already did that, then I’m sorry, I definitely relate to this, and it’s very frustrating, I was thinking of getting an M4 air but your response has kind of held me back and made me question my choices, how is it on the M4?
It’s not really that difficult, but in order to do it, You HAVE TO reset your mac clean first, You can look for tutorials, I really don’t know how to explain properly, I hope you can understand
Yes, Please do, I personally wait until 27.5 but please do note that all updates or versions have bugs, no matter what, it kind of varies though, but yes, stay on 26.7
This is what I do, I’ll stay on version 26 across all Apple operating systems until Apple reaches Apple software versions 27.5 or 27.6, Updating when an update is first released is risky in my opinions, you really risk bugs, issues and problems that were not in v26 in most cases.

You should start your own thread rather than hijack this thread.
Hopefully you did this prior to giving away your Mac:

After all this time, you expected otherwise?

M1 MacBook Air is sluggish after macOS Ta… - Apple Community
If the issues on the computer are presently occurring on macOS 26 Tahoe
The user would be better off resolving those issues before upGrading to macOS 27.xx of any point upgrade
Just an educated opinion
User Risk Assessment: macOS Downgrade Procedure
Before initiating any downgrade from macOS 26 (Tahoe) to an earlier version such as macOS Sequoia, assess the user’s tolerance for potential risks. The following checklist must be completed before proceeding.
Primary System Dependency
Determine whether the affected Mac is the user’s primary or only computer.
If the user cannot function without this system for several days in the event of a failed downgrade, the risk level is high.
The downgrade should be postponed or avoided until proper contingency measures are established.
Availability of a Secondary macOS System
Confirm that the user has access to another Apple computer currently running macOS 27 or macOS 26 (Tahoe).
This secondary system must be capable of performing a Revive or Restore operation on the target Mac’s firmware if required.
Lack of a secondary Mac significantly reduces the ability to recover from firmware corruption or boot failures.
Firmware Compatibility and Secure Enclave Risks
Be aware that upgrading to macOS 26 (Tahoe) likely includes a firmware update affecting the logic board and Secure Enclave Processor (SEP).
Downgrading to an earlier version (e.g., Sequoia) may or may not introduce firmware mismatch issues, leading to instability or loss of functionality.
Backup Integrity and Recovery Preparedness
Verify that the user has at least three complete backups created before the macOS 26 (Tahoe) upgrade.
Implement the 3-2-1 Backup Strategy:
3 total copies of essential data
2 different backup methods or storage media
1 copy stored offsite (for protection against natural or human-caused disasters)
Each backup should reside on a dedicated, single-purpose external drive.
For enhanced backup and cloning capabilities beyond Time Machine, refer to:
Recommendation Summary
If the user answers NO to any of the above questions:
Downgrading the Mac is not recommended.
Proceeding without proper contingency plans, verified backups, and recovery tools may result in:
Data loss
Firmware corruption
Secure Enclave failure
Complete system inoperability

They are happening on Tahoe! I just don’t think this is the right time to update to golden gate, I had to downgrade to sequoia to get back my Mac’s stability
There isn’t any inherent instability in either Tahoe or Golden Gate. If you had to go back to Sequoia, you likely have installed a third-party system modification that is not compatible with either.
What did macos 27.0.1 actually solve? 😅
