Thank you for the follow-up, Clyde.  Since it started again after a restart, it must have been Apple's server which felt the need to sync.  I wonder what on earth it was doing.  I was worried that you were going to have 100,000 bookmarks.

Indeed, SafariDAVClient is being a very busy beaver.  With all that activity, I hope it's only talking to itself and not really doing anything with your bookmarks or other Safari data.

If those devices are iOS devices, then you need iCloud.

Hello Clyde,

BookMacster is supposed give up waiting for iCloud after a given timeout, which is 15 seconds when you initiate an export manually, the timeout is 15 seconds.  It appears to be using the other timeout of 20 minutes instead.  We'll get that fixed.

Now, on to the real issue you're having.  Please try this…

• Try the Export to One Client ▸ Safari again, and see if it works now.

If you still get Error 613902,

• Activate Finder.
• Click in the menu: Go ▸ Utilities.
• Launch the application named "Activity Monitor".

You will see a window showing all the processes running on your Mac.

• Into the Filter field at at the top right, type SafariDAV.

If you see a process named SafariDAVClient listed, this indicates that indeed iCloud is either syncing your bookmarks, or has gotten stuck, and this is the reason why BookMacster won't export.  Although you can quit or Force Quit SafariDAVClient in Activity Monitor by clicking the Quit Process button, and this will free up BookMacster, I wouldn't do that.  I would restart instead.  Probably the effect will be the same, but when playing with iCloud one should take every possible opportunity to be nice, lest it get upset and produce thousands of duplicate bookmarks, as some iCloud users have reported, for example, here…

If you get Error 613902 in BookMacster when SafariDAVClient is not listed (not running), I'm going to have to think real hard.

Let us know what you find.

Finally, if you are not using iCloud Bookmarks to sync multiple Macs or iOS devices, you should switch it off.  You do that in System Preferences ▸ iCloud.

Hi Jerry,

I have had trouble exporting to Safari.  BookMacster hangs with status bar message,
Writing Safari: Waiting for updates by iCloud.

Stop Workers & Agents is grayed out.

I let it run for quite a while (an hour). 
Sometimes I have to force quit BookMacster.

Any thoughts?

Thanks,

Clyde


PS. I am managing all my bookmarks in BookMacster these days adding all new bookmarks to my Bookmarkshelf.
Periodically I sort (command+J) then export (command+U) to Chrome & Safari.  (no agents set.  2 clients set: chrome & safari, export check boxes ticked)
