Hi everyone,

I'm currently running the latest macOS 27 beta. With each new beta release, I've noticed that app compatibility and overall stability have improved, which is great.

However, I still have the feeling that the operating system itself has gradually become slower. Right now, it feels noticeably sluggish at times, even though I'm using a MacBook Air M3 with 24 GB of RAM.

Once the final version of macOS 27 is released, I'm thinking about doing a completely clean installation:

* boot into Recovery,
* erase the internal drive,
* install a fresh copy of macOS 27,
* then restore all my data, apps, and settings from a Time Machine backup.

Since I shouldn't lose any data, do you think this is worth doing? Has anyone experienced a noticeable improvement in performance or overall system responsiveness after a clean install followed by a Time Machine restore, compared to simply updating from the beta to the final release?

I'd really appreciate hearing your experiences and recommendations. Thanks!
I do a complete wipe and fresh install on all my Apple devices every year when the new OSs are released. Only difference is that I don’t restore from a backup - I “set up as new” then log into iCloud and let my data resync. It’s actually a quick process - installing a fresh OS is much quicker than upgrading. I do have to re-install my apps manually, but again this doesn’t take long and it’s a good opportunity to just install the stuff you use regularly and forget those apps you never use. My personal opinion is that most of the issues I read about on these forums would be solved with a wipe and fresh install 😂

This has been precisely my strategy from the start!

It honestly removes so many problems others report. It serves as 'spring cleaning' as well, as by the time a year runs through my phone is packed with apps I've tested and don't use, and my laptop is packed with experiments that start to grow fur =)

There's a new Shortcut action in macOS 27 that lets you integrate Describe a Shortcut into other shortcuts, producing a new shortcut as an action output. The generated shortcut will also appear in your gallery.

Generate Shortcut

Generates a new shortcut from a text description using Apple Intelligence.

Description

A natural language description of what the shortcut should do

Result

Shortcut

Shortcut link with Generate Shortcut action

It's currently hidden from the actions drawer, but you can copy it from the shared shortcut linked above. Discovered via the Shortcuts/gen_shortcut_prototype feature flag in macOS 27.


Two more feature flags (use_model_sampling_mode_parameter and use_model_thinking_effort_parameter) hint that we may see additional options for the Use Model action in Shortcuts. No sampling or reasoning parameters show up right now when the flags are enabled.

By the way, thanks for digging up all these new things. I appreciate your posts.
 
In macOS 27, AirPlay can finally start off in windowed mode instead of taking over your Mac's full screen.
