installed MacBook Pro 2.0 update, and many problems exist!! Mac OS X now continuously asks for "login" keychain permissions; DVDs refuse to eject after pressing the eject button and/or click eject both in DVD player and Finder; the MBP itself seems slow!

tried repairing keychanin and reparing permission but got no luck.... ive been dealing with this bug for a week now 😟 can you please Apple fix this issue ASAP!!!!!!

I'm also experiencing hangs when it tries to come out of sleep. I'll see the cursor flash quickly against a black background and then the display turns off. About 5 seconds later, it repeats.

This forces me to force the power off and reboot, thus enhancing my overall frustration with Apple Quality Assurance and Dev teams on this one.

I found also another awful bug: holding command-r on boot always starts internet recovery! To access my recovery patition I pressed option key. Now I'm restoring from TM to avoid this insane update.

now Im facing new issue here.... not sure if you guys have encountered the same but when my LCD is at sleep, then pressing any key to wakeup the screen will just give you a blink from the screen, pressing any keys will do the same (blink the screen even keyboard lights) goes back to black screen so totaly I cant use it anymore unlesss I long press the power button to do force restart =< it will give me wierd sound of hy hard drive when forcing the laptop shutdown... oh dear I hope that my HDD wont be affected!

I've been having this login keychain password request and all of my email passwords too every 30 seconds or so

Found a link on another forum suggesting repair disk permissions using Disk Utility. Then Reboot. It found and repaired a whole bunch of broken permissions and then once I rebooted It asked for the passwords once again for messages and facetime and when I opened mail.app I rebooted again and havent seen the problem for a couple of hours now. Fingers crossed.

been doing same reparing disk permission and reparing key chain but problem still persist.... 😠

Hello all!

I've a MBpro 13" 2,7ghz 8gb ram mid 2012 and encountered the same login password problem.
Once when I put my screen to sleep, I woke it up again and the screen was just blinking and again sleep, I could not wake it up and the solution was to force it to shut down. But than it did not make that problem again.
Another thing could be the light sensor, which sometimes does not work and I've to wake it up somehow: changing a bit the brightness and changing the light conditions until it starts to work again.
I did not see any lower-performance issue, but the login to keycan-stuff is really annoying!
But since I repaired the permission the mac is asking the login password not so often at before.
Hope this helps to you but overall to Apple for making us a good update! 😉

I am having same issue with blinking screen when my MBP is at sleep and waking up.... and my only resolution to fix this issue is to force shutdown (kills my HDD!)😢

Comiserating with everyone. My MBP Retina is doing the same things.

• 1 second blink when attempting to wake from sleep.
• I haven't had a master keychain issue, but email logins and messages apps loose passwords and then don't accept known good passwords until a restart.
• Slight sluggishness.

I have tried the following.

• Restart
• SMC Reset
• PRAM Reset
• Repaired Permissions
• (Not enough time to evaluate this one yet) Reinstalled 2.0 update from Apple website download.

I've had same issues as afore mentioned on my 13" MBP. What bothers me is that Apple hasn't responded to this feedback yet its really taking a toll on time and productivity!!!

I'm attempting to reinstall the update.

If reinstalling helps, please post back.

Reinstalling won't help if you also install this update. Either roll back using a Time Machine backup, or re-install the OS and don't install this update.

I myself have reverted back to a Time Machine backup taken on Friday evening. All is well again.

I experienced the login keychain notifications. Mail wasn't even usable - I have 6 mail accounts added and it was an exercise in futility keeping the thing open.

Also experienced the DVD drive wouldn't eject discs. I have an external drive attached to USB hub which is connected to my Retina MacBook Pro.

The Mac wasn't sluggish, but I performed an SMC and PRAM reset after applying the patch, so perhaps that helped?

No screen flickers that I noticed.

I usually don't bother with the Messages app unless someone is trying to reach me.

Before I went back to a certain backup in Time Machine, the 2.0 update did:

• annoying 'login keychain' notification
• Messages app failed to work
  • app didnt recognize my email signed in
  • failed to send / receive messages
• a very sluggish response of the Mac
• DVD driver wont eject CD/DVD
• random screen flickers

I reinstalled the update. It seems that my issues with a flickering screen after resuming from hibernation have stopped. I also have no issues with keychain and messages as well.
