I am still suffering from this. I tried a lot of ways. For instance, I removed the login KeyChain and created a new one. But it can't hold new items inside except I secured WiFi network. All the rest passwords can't be saved here.

all the rest content can't be saved here

I recently updated to the latest macOS Sierra. Though I am not completely sure whether this is the cause, my "login keychain" was totally ruined since then.

Every time I restart my Mac, I got a popup alert like this:

The system was unable to unlock your login keychan (Please ignore the scar on my screen)

And when I opened the KeyChain App, I got this:

readonly

It says it's "Read Only".

Now I have to re-enter every password again (like check my email, log in my StackOverflow account, log in my facebook/twitter). And this happens every time I restart my Mac. It's so annoying. What should I do to fix this?

Thanks!

  • Let me know if you get an answer, same thing here. I created a new keychain to get rid of the error, but I had hundreds of seldom used sites stored in there that I no clue what the passwords are anymore. – Keith Samuels Oct 7 '16 at 14:41
  • Try creating a new user account on the same mac and see if it happens there too. – orkoden Oct 19 '16 at 8:57
  • Issues such as this are common if you 'upgrade' the OS over a well used older operating system. You effectively end up with a hybrid and a preference folder full of garbage. Always back-off your Mac to a remote drive (twice), wipe the primary drive clean (or better install a new one) and install your new OS clean. The re-install your software and import your data back onto the Mac. Takes longer but works every time. – Applefanboy Oct 31 '16 at 11:36
  • I have huge files on my mac and if I backup every time it's like a nightmare. I'd rather stay at the old ways :( – AGamePlayer Oct 31 '16 at 12:15
  • Did you try this: open your keychain, click on the lock symbol to unlock (enter password), then quit keychain leaving the lock open. – not2savvy Jun 28 '17 at 10:41
