I can't set up my Google Accounts on my MacBook Pro. When adding my work (one step) or private (two-step) Google account in the internet accounts panel in system preferences, it doesn't go past this screen. When I select the apps to sync, I can click Done and then Done get's greyed out. I see the grey spinning wheel very shortly.
For the calendar, I tried this but without succes:
Can't enable Gmail calendar syncing
I've had this issue on Yosemite as well, but now also for el Capitan. Other sites suggest going on a different network would solve the issue. I tried wired, WiFi and a mobile hotspot I created with my phone without succes.
It seems that in the process I'm going one step further than this guy Internet Accounts – Login Issue with Google and iCloud. I'm running out of options and frustration is growing strongly. Thinking about doing a clean install.

This issue was plaguing me for a long-time and was really annoying.
I initially thought it was an issue with a random plist or other file hanging out in the Library/ folder and I tried deleting many of them to try and get to the bottom of this.
Eventually, I was tipped off to a Keychain issue by looking in Console, which with some Google'ing, led me to this post on Apple's forums.
Ultimately, I removed all of the following items in Keychain Access, retried adding the account in Internet Accounts, and everything worked well!
It sounds like it was only the com.apple.account.Google.oauth* tokens that had to be removed, but your mileage may vary.
