sorry about the delay.
I don't currently have a manual, but the following Settings will probably give you a reasonable start:

@SweetP I would say it's better. I'm not keeping track of time Safari is up front but sometimes I just leave the Safari screen up for an hour or two yet nothing is saved. So it's unpredictable but, yes, I AM getting occasional saves, which is probably sufficient.

Perhaps when a screen saver kicks in Safari no longer is seen as active?

I’m hoping v2.6.9 fixes this

This should be fixed in v2.6.8

@Pilou Thats not currently possible unfortunately

@sonata31
Session Data is saved to the following location:

@EMPF1969 woah, that is certainly not normal 😬
do you have a large number of sessions saved?

have you tried restarting Safari, SessionRestore and your computer?

@themainaccount as long as yore not deleting SessionRestores container folder, it should be ok.

you could export all your sessions first just in case
🙂

@nelly I am experiencing same issue on macOS 11.6.2

It's become so unpredictable that I had to stop using it. After some time I decided to seek support and found your post here. Rather than creating a new post I'd like to vote on this.

@joe-l there are no APIs from Apple to get data on tab groups... When (If) Apple adds support for this, then I'll also update with tab group support...

sorry I don't have any better news
😞

@sweetp Thank's a lot!!! Great Support!!!

SessionRestore doesn't support importing from Tabs Saver.
If you post a link to the extension.
I could install it and take a look at its export format, to see if I can make SessionRestore compatible

I don't think its possible,
support for the functions SessionRestore needs in Safari wasn't added to Safari until v12., macOS 10.14.4

Hello Russel, thanks for the update today. I have again trouble synchronizing the two Macs. While streaming the logs in Console, I got errors like this one:

error: CoreData+CloudKit: -NSCloudKitMirroringDelegate recoverFromError:: <NSCloudKitMirroringDelegate: 0x600003118000> - Attempting recovery from error: <CKError 0x6000004ff7e0: "Partial Failure" (2/1011); "Failed to modify some records"; uuid = F52CA680-FE76-4CA7-846B-B9BB86D27264; container ID = "iCloud.com.sweetpproductions.SessionRestore"; partial errors: {

I hope it's somewhat helpful.
