OK! Mac OS Tahoe has Very Slowly revealed All My Bookmarks

Patience paid off! I expected my year 2000 M1 MacBookAir became 'like a brick' after mistaking upgrade to Mac OS Tahoe. Not So, all my BookMarks were found after days of patient attempts to recover them. I'm not sure my M1 will continue well with Tahoe. So I'll buy a BackUp Device to Store Tahoe, then ReLoad the previous OS. That will ReCover the familiar management of my M1. Not Sure about the method to accomplish that M1 Return to the previous OS, but I've encountered several Guides to do so. I'll stick with the method I trust. Yeah, I was ready to purchase a M4 MacBookAir; but I'm biting the bullet these days after paying off all my Credit Cards and recovering a much better Credit Rating. I've had ENOUGH ALREADY of Credit Card interest costs! I'll post more after completing my Step Back to Mac OS Sequoia. Yeah, I know! I'm showing my inexperience with Operating Systems. I hope my remarks are useful to Apple Community Members.
