I have ran into exactly the same issue on my end. It's really annoying albeit I guess it, quite benign. Anyhow, precautions and directions should be in place, so even if you only boot up the Mac once per day, the 10-second flat beach balling is one too many.
- Starting up in safe mode didn't solve it for me.
- Neither did deleting Finder preferences.
- Isolating the Mac from the (wired) Network… nada.
This occurs only once after booting the Mac. It could be a right klick on the desktop or just a klick in the finder menu bar.
Do you mean the whole OS X menu bar or maybe ONLY the "File" item in the menu bar? On my Mac, the issue shows up when clicking on the "File" menu, so my suspicions were toward Finder tags as I am a heavy user of those. So far Edit, View, Go, Window… those don't trigger the beachball. Just "File" does.
So, upon this, I short-listed the suspects, namely:
- FindePop (residuals) I had FinderPop installed on Yosemite. And it's known to be incompatible with El Capitan so it is longer gone. So after running EasyFind I stumbled upon and deleted remaining files associated with FinderPop. While this didn't do the trick, I won something like 100 KB on HD space.
- MailTags, (Mail Plug-in) Remember when I wrote I was a heavy tags user? Well, this is it. Besides adding tags and a helluva of Finder/Spotlight comments to most files I "own," I do the same with e-mails. So it occurred to me that maybe it was too much for the Finder to deal with. So with the help of the Mail Plugin Manager app, I disabled the Mail plug-ins I had running on my Mac, (Mail Tags and Send It Later) but alas, this didn't help either. In all honest, I should clarify that I thought deactivating these was the key to solve the issue as the beach-balling on start-up/restart did show up again… until today. So there it goes what I had foresaw as my savior.
Also, quite interesting fact: if I go to
Menu > About this Mac…
Overview, Display, Memory… those panes respond to a mouse click promptly, BUT, Storage? the 1st time you click on it, it takes 10 seconds (geez, how coincident can get it!) to the pane to react. I should point out that there is a Boot Camp partition with Windows 10. And that the burner is kind of present there, as it is on the Apple menu and the contextual menu… however I fail to see the burner leading to this no matter how much it's been depreciated by Apple.

That's all I can think of right now… more to come.
