How can I restore macOS Tahoe to the version of macOS Sequoia ?
My Experience with Tahoe:
1. Spotlight : Incomplete search, low efficiency, compared to the previous version
2. Safari : The Personal-collection-folder hierarchy is too deep. If there are folders, you need to click many times, which is extremely inefficient.
3. Some software windows are responding rather slowly.

Reverting to Sequoia is not simple. You need to boot into Recovery OS, erase your internal drive, then install the older macOS, then restore from a backup made prior to the Tahoe upgrade. Even then, the firmware on the Mac may have been updated, meaning potential conflicts and a possible need for DFU mode and a Configurator revive/restore, which would need to be done via another Mac connected to yours. If that sounds complicated and risky, then you're assessing the situation correctly.

Regarding the points you mentioned..
1) Rebuild the Spotlight index on your Mac - Apple Support
2) I see you point if using Show All Bookmarks, personally I just use the Bookmarks menu (in the menu bar) and drill down that way, which I find fast and requires no clicks
3) Specifics would help there.
Thank you sincerely for your reply. Listening to it is indeed both complicated and risky. So we can only hope for the new version. However, this current version really hinders our work efficiency. I hope Apple can improve and release the latest version as soon as possible.
Thank you for your information. I updated from Sequoia yesterday and have discovered that Tahoe has filled most of the available disc space on my Mac mini (M4), with no obvious way of recovering it. It looks as though I will have to live with the peculiarities of the new system. I will look forward to the next update...

Reducing System/Volume/Data is a common question.

There are two effective ways to remedy this issue:
1. Quick Fix Actions:
For Apple Silicon computers, use Disk Utility to erase a Mac.
Always make a Time Machine backup before proceeding.
Migrate only the user account, not the entire system.
Reinstall only the necessary applications from the Apple App Store or directly from the developers.
2 - Generally
When the user discovers this issue, it’s likely because the computer’s internal drive capacity is small, such as 256 GB or 512 GB. Unfortunately, the user’s storage needs may have increased since the computer was purchased. To future-proof the computer, consider spending extra money upfront on a larger drive capacity and adding more unified RAM.
Note - On Apple Silicon and newer computers. The SSD Drive and the Unified RAM are Soldered to the Logicboard and can not be upgraded.
