Downgrade from Catalina to High Sierra

[saadat]

Hi,
I have an old MacBook Air 2012 model. I upgraded to Catalina, which made the system very slow, to the point, that it not at all usable. So, I decided to downgrade to High Sierra. I clean installed High Sierra. However, I faced issues with Safari history, which was not restored from iCloud. I had taken a TimeMachine backup as well, which I used to restore the History.db file and I still did not have my history. Then I deleted the restored History.db and started Safari again, a new History.db file was created; again, empty. Basically, I've tried Turning Safari off and on in iCloud settings, used the debug menu to force sync history and used a TimeMachine copy of History.db. Nothing worked!

I suspect that the issue is because of incompatibility of newer version of History.db file. Apple to known to prevent backward compatibility, like the user files in iWork Suite. Can anybody please suggest if there is a way to restore my history? Thanks.

P.S. I have my entire history on my iPhone and its not having any issues. Thanks.

Many Thanks,
Saadat

Try turning on Safari iCloud history on both your iPhone and your Mac and see if that does the trick.

No, it was already on for both the devices. I turned it off and on, on iOS. Then tried syncing from the Debug menu on MacOS Safari. Still not working.

Since iOS 13/macOS 10.15 iCloud bookmarks are end-to-end encrypted, so I suppose there is no way to get at the data without syncing it properly through iCloud. Make sure that you are using the latest version of Safari; maybe you can try the Safari Technology Preview.

Other than that, you will likely have to start over or upgrade to Catalina to access and export them from there.

Syncing does not work. I tried multiple ways for that. Is there a way that I could export my history from iPhone Safari? Once its integrated, it won't be a problem later on.

In the past it was possible to sync bookmarks via iTunes (now presumably Finder). I do not know if this is still an option however, as you’d have to turn off iCloud sync of bookmarks. I have no experience with third-party tools that undoubtedly exist.
