If you'\re going to restore everything from a TM backup, then you'll end up exactly as you are now.
Got a tip for us?

Hi,
I didn’t quite get a clear answer, so let me ask in a different way.
Based on your experience, does performing a clean installation of macOS and then restoring my data from Time Machine typically result in a faster system compared to simply updating from the beta version to the final public release?
I’m interested in your real-world experience rather than a theoretical answer.

Every time I've used Time Machine for any kind of restore, I've had to sort some files manually.
I update using the full installers (and IPSW files on my iPhone).

Your "clear answer", based on my experience and knowledge of Apple's implementation of uts OS system, since High-Seirra with the advent of the signed and sealed OS system that cannot be edited, or otherwise changed at all, is there is absolutely no difference in the speed at which the OS can operate on any particular hardware. Zero.
Change the hardware, for example ditch using an M1 MacBook Air and use a maxed out M4 Max MacBook Pro and you will see an increase in the speed at which the system operates.
If your Time machine backup contains items that slow down the operation of a system, it is obvious that the speed may be affected, and the question of if it is noticeable or not depends on the individual running the system.
Some people have had issues with TM and some swear by it. I personally use CarbonCopyCloner, and do not have a TM backup.

No. Restoring from Time Machine leaves the reinstalled system in the same state as it was before the reinstall.
If you really want a clean install, back up all your files, apps, and whatnot to somewhere external, erase and reinstall, sign in to iCloud, but set up as new, then drop your filters and apps where they belong. It takes a bit more time, but it works.
All the junk you’re trying to escape is backed up in Time Machine, and is just rolled back into place.
[source: have used both options myself over the last 20 years]
You want a clear answer? A Time Machine restore ALSO restores the settings. In other words, a clean install will have nothing at all set… which is ruined by restoring from Time Machine. Would this make a difference? Eh. Depends on what is being restored. But there’s no real point to do a clean install if you are just going to put those settings right back.
If you have a Time Machine backup from BEFORE the beta, it might be arguable that it might help since you are restoring to before the beta clutter. But a manual restore by putting things back by hand (as the other commenter stated) is the only thing that would maintain the ‘clean’ state that you want.

If you want the cleanest, fastest, most optimal-running Mac, then do a complete erase and install.
That being said, it doesn't yield the same results that it did years ago before Apple started locking down the system. You simply can't screw up your system as easily as you used to. Doing a clean install back then yielded stunning results with regard to speed. Nowadays, the difference is usually barely perceptible.
Doing a simple upgrade will still (as it always has) bring old propblems with it, such as corrupted preferences and cache files, etc. But those are generally easy to fix.
I used to do an erase and clean install with every major upgrade, but I skipped it once or twice and noticed that i was still seeing speed increases due to the new system – but it's probably because I didn't have any issues to begin with. I haven't done an erase and install in years.

If they keep the two-week cadence going, you can expect it on Monday.
I'm running Parallels on public beta 2 on a Mini M4 without issues (so far). It's a Win11 ARM VM that I use primarily to run an ancient version of Quicken (2001) which remarkably still works, along with MS Office and Steam.

Like the person above you said, if you restore from Time Machine, you're going to be right back where you were. That's the whole point of Time Machine. It *restores* your system to where you were

For me clean installations are a PITA but that is what I do oppose to a TM restoration as that operation will no doubt put you right back to where your problem started.
A clean installation gives me a vanilla system so to speak, the next step I do is run 'First Aid' in 'Disk Utility' on all the volumes to see any errors. That is a ritual I perform without fail after seeing many errors from a TM restoration in the past.
The only bind is installing all your programmes once more but for me as a retired person, time is not a problem for me in that aspect.

Yeah, me too, but now on Apple Silicon… how do you do such a clean install? Booting into the restore partition and then erasing the whole drive? Then, how do you install the operating system?
What happens if you just delete the AI package? I don't know where the AI system is stored or how to check the size as other people have been doing, but if I find the directory, can I just delete it?

Yes! A clean install of macOS will ALWAYS be faster than an in-place upgrade from one version to another.
Regarding restoring from a Time Machine backup: If you restore *everything*, you end up with the same files back. However, you can back everything up but restore only your personal user account files—skipping the system files and settings.
You can customize this process to suit your needs. I’ve been doing this since Catalina, and every year my Macs run faster and feel brand new.

Considering the volume with the OS is locked, how are you managing to degrade your system such that it slows down compared to having exactly the same software and data after a clean install?
Edit: Genuine question, as I'll also do a clean install if it definitely speeds things up!
