Double authentication upon wake from long sleep

Hello - When my MacBook Pro (details below) sleeps for more than 12 hours or so, it goes into some kind of deep sleep. I authenticate, it gives a little progress bar at the bottom of the screen as if it is resuming OS X or something, then I get the same authentication screen again to log into my computer. But the second screen is not active for quite a while, maybe 2 minutes or so (I cannot type, the trackpad does not register any movements, etc.). Then finally I can start using the computer.
I changed the hibernate settings to traditional sleep mode (suspend to RAM), but that did not do anything that I can tell to solve the problem. Can anyone help me with ideas about how to fix this terrible situation? My older iMac does not exhibit this behavior at all.
MacBook Pro (13-inch, Mid 2012) 2.9 GHz Intel Core i7 running 10.10.3

I am really not convinced that this is a "display" problem in and of itself now since I have seen scores of posts throughout the Apple Forums with various Macs and Displays that complain of the same symptom.
I have been chasing this problem now for 3 months (looks like it started for some people going back to at least September 2009). I have (3) identical SONY 23" CRTs connected to my Mac Pro via two PCI video cards, but I am having trouble with only ONE monitor so far (doing the same thing you describe in previous posts - won't wake up from a long sleep - a few hours).
• First I purchased a new monitor cable for the monitor in question - no change
• Next, I purchased a new VGA to DVI Apple Adapter - no change
• Next, after talking to AppleCare Tech support and trying SMC reset, PRAM reset, etc. they sent me a NEW ATI 2600 video card - installed new card - no change
• Tried swapping suspect monitor to connection on other card (known good card) - same monitor would not wake up!!!
• Purchased new GT-120 video card to replace the new ATI-2600 - same problem.
This leads me to believe that it is either a problem with the OS somehow or perhaps some monitors just need a stronger signal to wake up??? Maybe my 3rd monitor is just getting tired compared to the other two and need a bigger kick to wake up?? Maybe some of these new flat screen LCD/LEDs need that extra kick out of the box?.
All I know is that I have seen scores of complaints on this issue all over these forums with different Macs, Different types of displays (new and old) and various video cards - the only common denominator I can find is the OS.

  • Since Lion, primary monitor doesn't wake from long sleeps

    Since installing Lion, my iMac doesn't wake properly from sleep when it's been off for a while.
    I have two monitors and the second one wakes fine, but the main one - the iMac itself - doesn't return unless I reboot.
    Any thoughts?
    Thanks

    Try turning off hibernation mode - run the following in terminal:
    pmset -a hibernatemode 0
    You'll likely need to do that from an admin account using sudo.  The reason why this happens, I think, is that you close the lid and sleep the machine while the system is in the middle of doing something (updating the hibernate sleepimage, locking the screen, etc...).  then when you open the lid, the system is still going through the close-down process and the monitor wake call gets lost in the shuffle.  turn off hibernate mode to speed things up, only turn it back on when you need it (like when you're in a situation where you'll need to switch batteries without a power cord). 

  • Wireless connection lost upon wake from sleep

    I recently joined the 21st century and purchased broadband internet for my home. I am connecting via wireless ethernet using an original Airport card and flying-saucer type base station. All I did was connect the base station to the cable modem with an ethernet cable, plug it in, and restart my eMac. The network showed up right away and I was connected. Unfortunately, after my Mac went to sleep and I woke it up, not only was there not a connection, but there was no sign of the network.
    Airport status showed it was still on, but in the spot where the networks show there was nothing. Restarting corrected the problem, but I assume only until it sleeps again. I can change the settings to make it monitor-only sleep, but I would like a more permanent solution.
    What might help to fix the problem, and was there something I needed to do besides just turn my machine off and on to set up this network?
    Thanks.

    If you pose this problem over in the Airport or Tiger networking forums, you'll find you've stumbled into a morass of conflicting reports. There have been a disturbing number of reports of Airport connections lost in Tiger after wake from system sleep, usually not reconnected until after a restart. Some people have some success checking the box to put the Airport icon in the menubar ans using that to turn Airport off, wait a few minutes, and turn it back on, yet others have reported that only works part of the time and others report it doesn't work at all. Some have reported improvement after downloading and running the full OS X Update Combo 10.4.10 (PPC) on top of an OS updated via Software Update. And the large majority of Airport users never report any problems at all using Tiger. It really sounds like there's no one cause and no one fix.
    There is a workaround: don't let the Mac go into system sleep. Use the Energy Saver system preference to set system sleep to Never, uncheck the 'put hard drives to sleep when possible' box, and set the display-only sleep to say 20 minutes. If the eMac is in a bedroom and the sleepers are sensitive to fan noise or power LED lights, that will be a problem, but likely less aggravating than losing your broadband connection.

  • My iMac 24" late 2006 refuses to wake from deep sleep,

    My iMac is refusing to wake from deep sleep or from a shutdown, will start if I persist in either using safe mode or command mode (cmd + s)but can take many attempts, have repaired permissions and verified disk, on permissions it is constantly changing the permissions on preference panes as listed below, but this is a shortened view, there are 23 lines like this.
    permissions differ on "SystemLibrary/PreferencePanes/Displays.prefPane/Contents/Resources/sk.lproj/Di splaysPref.nib" should be drwxr-xr-x they are -rw-r- -r- -
    Would it be ok to trash the Preference Pane folder and let it rebuild ???
    Any help welcome

    Helio, you can mostly ignore repeated Permission Repairs.
    To remove Prefpanes, right click on one & nchoose Remove.
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • 890FXA-GD70 Will Not Wake From S3 Sleep

    890FXA-GD70 will not wake from S3 sleep; the power comes back on and the fans run but the video never returns and the system hard locks with a POST code of 22 or 24. Other than this issue the system is rock solid.
    Windows 7 Ultimate 64
    AMD Phenom II X4 955 Processor
    Sapphire 5870 Graphics
    Crucial M4 SSD
    Corsair DDR3
    No overclock
    I have reproduced the issue on two 890FXA-GD70s motherboards and I am convinced that this is not a result of a failed motherboard. I also was able to move my fully installed SSD hard drive, processor, memory and graphics card to an Asus 890FX board and successfully wake from S3 sleep proving that my OS and driver installation are working correctly.
    I know how to properly set the BIOS as I have installed many 890GXM-G65 motherboards for S3 sleep without issue. The problem seems unique to the 890FXA-GD70.
    Is there a fix for this?

    I have identified the cause. The "Extra RAID/IDE Controller" must be "Enabled" to use S3; otherwise the system will hang on the wake event. This is true even if the "Extra RAID/IDE Controller" goes unused. The "Extra RAID/IDE Controller" must be set to "Enabled" for S3 sleep to wake.
    This would seem to me to be a bug since none of the other MSI boards I have used require the optional IDE controller to be enabled in order for S3 to function properly.

  • Macboor air 13 late 2010 freezes when wake from deep sleep

    Hi. I have had this problem for a few months and still havent found a solution. This macbook air freezes and is totally unresponsive for five or six seconds when it wakes from deep sleep. I have tried:
    1 Apple hardware test, which came up negative. No hardware problem detected
    2 reset the SMC several times. No fix.
    3 repaired permissions in disk utility, and also verified and repaired disk. Still no results.
    4 restarted many times.
    5 tried booting in safe mode, but it made the machine hang.
    The only thing I havent tried yet is resetting the PRAM. in the event that that doesnt work, does anyone have any ideas. I only found thre

    I think it might just depend on how often your machine does this. My MBA 13 has done what you are describing one or twice, but its a rare event. I'm not too worried about it, but you might want to contact AppleCare and see if they have any more information...

  • MBP (early 2009) won't wake from Display Sleep

    My MBP has started to not wake from Display Sleep (the machine is not sleeping, only the display). The only way to get it back is to force power off by holding the power button down.
    The weird thing is, when I power it on, it shows the 'loading RAM from disk' progress bar down the bottom of the all grey screen, as if the battery ran out. But I have it connected to a power source. Once it loads the RAM, the screen goes blank and it hangs. Another force restart and it boots to the login screen as per normal.
    One thing I have noticed is that when this all happens (ie, when I try to wake it and nothing happens) the fans are on about medium speed and its very warm, as if there is some process thats causing high CPU usage and preventing the display waking. I usually have a few browsers open, iTunes, etc, nothing out of the ordinary.
    I might try connecting via screen sharing next this happens to see if its responsive over the network -- i'll post my findings here.
    I have screen saver with password protection turned on, and its connected to an external apple display.
    Has anyone else experienced this?

    Try a SMC reset.

  • Launch application upon wake from sleep

    Is there an automator that will launch an application when the computer wakes from sleep? I do video chats w/ my elderly mother via iChat. I can wake her computer from my home using WakeOnLan. However, she sometimes quits iChat so it is not always running. I would like to have some sort of automator set to launch iChat everytime the computer wakes from sleep. I assume if iChat is already running, it would not matter.
    If anyone knows how to do this or if it is even possible, please let me know.
    Thanks,
    Randy

    Gary,
    Thanks for pointing me in the right direction. I ended up using DisplayWatcher as it also has the ability to run an automator application upon waking from sleep. There were some other apps that were too complicated for me -- had to enter Unix commands/code and I did not understand how to do this.
    Thanks again,
    Randy

  • Time Machine "preparing backup" eternally upon wake from sleep

    at a bit of a loss here...
    iMac 24" (version which offered 7300GT as BTO option)
    10.5.5 with all updates applied
    LaCie 500 gig USB 2.0 drive directly attached.
    Up until about two months ago, Time machine functioned fined. Then for some reason, the following started to happen. (no known reason, no software update related etc, that I know of)
    scenario... Time Machine functions correctly EXCEPT when waking from sleep. If iMac wakes from sleep and attempts a backup immediately (e.g. more than one hour has passed), it gets stuck "preparing backup" forever. I've let it run overnight (actually as long as about 30 hours), it never stops. Finder and other programs become extremely non-responsive, machine is almost unusable. Literally, the only way out is to manually shut down external drive, with attendant warnings/errors.
    What I've done:
    1) deleted the time machine .plist file
    2) erased, repartioned (as a single partition) external drive
    3) started brand new time machine backup (takes about three hours)
    At this point, time machine will backup up fine... I can force a successful backup, if I leave the machine running, at one hour it does a successful backup.
    BUT, as soon as it goes to sleep, time machine is hosed.
    The only workable method for using time machine is to turn the external drive and time machine off when not using it, and turn the whole shootin' match on to do what essentially becomes manual backups. These backup are fairly lengthy, as time machine also does lengthy "preparing backup", but they complete in about 30 minutes to one hour.
    Given that time machine doesn't give mountable/cloneable backup, I'm probably going to go back to Carbon Copy Cloner. Still, I like the ease/regularity of Time Machine, and would use it if it works.
    Any ideas?
    thanks

    It could be a number of things. There are lots of things that Time Machine does in order to "manage" backups -- apart from just copying data to the backup drive.
    It has to manage the transition of hourly backups into daily backups and must also transition daily backups into weekly backups. Each time it does this it has to move a lot of data around. It also has to maintain indexes of everything so you can quickly find backups should you want to perform a restore.
    I've also noticed that there are circumstances that can cause TM to question whether it can trust it's existing backup database... I've caught Time Machine saying that it needs to do a "deep traversal" of the backup (basically it wants to check and see what it really has) and this can take a very long time.
    Still... 30 hours is an extremely long amount of time. I'm almost wondering if there's a problem with either your USB bus or your drive when they wake up such that you may be getting a huge number of retries on something that should have happened quickly.
    I'd suggest you start the "Console" utility, select "All Messages" at the left, and then watch the messages being written to your log file. Not only does Time Machine log all of it's progress messages to the system.log (in more detail than you'd see in the Time Machine UI), but so do lots of other system processes. If you're getting USB bus problems the error messages would likely show up in the same log. I'm especially suspicious about non-TM related causes since you said you've already blown away your TM backups & preferences and started from scratch and you're still getting the problem.
    Try re-creating your problem with the Console log messages being displayed and see if you can't see something in the log that would let you get a little closer to the root cause.

    Tim

  • Screen blinks/flashes upon wake from sleep. is this normal?

    I just got my Macbook a few days ago and started to notice that my screen flashes or blinks when it wakes from sleep. I have searched on Google and haven't seen any one post about it so I'm guessing this is normal. This is not the flicker of brightness that other people are talking about.
    What happens is: I press a key or open the lid to wake it from sleep, and then very briefly for a second I will see the screen flash on (sometimes you can see a small image of the desktop), then it is black for a second, then the screen comes on normally. The delay of the screen coming back on after the blink seems to be getting longer so I was starting to worry this might be a problem. (granted the delay of the screen coming on is maybe like 2 seconds, but its noticeable) I had a Thinkpad previously and never noticed the screen acting like this.
    If anyone can tell me if I need to bring this in to the nearest store or if it is normal I would appreciate it. I don't want to overreact as this is my first Mac and I don't have any problems so far. But I want to be safe if this is an indicator of future screen problems. Thanks!!
    Macbook   Mac OS X (10.4.8)  

    Take it to your local Apple store and they will send it off for repair. Or call Apple and they will send you a box to mail it in for repair.
    I took my MacBook to the Apple store for the infamous screen flicker problem and they had the logic board and the LCD replaced. Problem is gone and the screen is better than before!

  • Creaking sound upon wake from Sleep

    I have only had my MBP (very first mac) last 1/25 and for a few days would wake from sleep totally silent.  In the last couple of days occasionally it wil make a creaking sound for a couple of seconds after I raise the lid sounds kinda like gears. Not very loud tho.  But since this is a refurbished (june 2012) unit I was just wondering if this is normal.  My old toshiba would always make creaky gear sounding noises at wake from sleep for much longer.  But since it is silent it is silent most times I was wondering if this was normal or a known problem?

  • Alert beep upon wake from sleep

    Hello,
    I seem to have a strange alert beep that occurs when waking from sleep.
    It only just appeared after I applied the 10.4.8 software update.
    I wouldn't be concerned but today when I booted-up my machine immediately kernal paniced and told me to restart.
    It seems independent of what software is open.
    I can't seem to find any start-up items that could be to blame.
    Any thoughts on trouble shooting this?
    Thanks in advance,
    Andrew

    I just repeated the beep on wake from sleep.
    Here is the console system log from before and after the sleep session.

  • Black screen upon wake from sleep when I change power state while in sleep

    Hi,
    I'm having this problem where my MacbookPro won't always wake from sleep.
    OSX is 10.6.3 and fully updated.
    I've done a lot of troubleshooting, and I can now replicate the issue 100%:
    1 - Put the MacbookPro to sleep by closing lid
    2 - Change power source (from plugged-in to battery or vice versa)
    3 - open lid - MacbookPro will wake, but stays at black screen and is unresponsive.
    Only if I change power state while sleeping will this issue show. Anyone else experincing this issue, and anygot got a clue on what to do?
    regards,
    Lasse

    I've seen the same issue after upgrading to 10.6.3. I have a one year old MacBook Pro. I would have the screen be black after coming back from sleep or hibernate (tried both).
    The workaround I found is to close the lid -almost- all the way and then immediately open it back up again, like I am catching the Mac going back to sleep and then changing my mind. For whatever reason, this has been reliably solving my issue for the last couple weeks reliably.
    Only other oddity I noticed is that immediately after upgrading OS X told me that my one year old battery needed to go in for servicing...
    Anyway, now all looks right with the world assuming you don't mind a quick close/open cycle.. Lovely...

  • Airport issue upon wake from sleep

    When my mac pro wakes from sleep it connects to my preffered wireless network but it has some serious issues and doesn't work. When it restarts the airport icon shows connected, but mysteriously shows a weak signal and when I try to do anything that needs to talk to the network it fails. The only way to fix the issue is turn airport off then on again and hey presto I'm back on a full signal and can surf n stuff.
    I'm using a 1st gen Airport Express N basestation, which works fine as I have 5 other macs in the house (non a mac pro) that don't have the issue.
    Looking in my logs i see a few interesting things, it looks like when the system is woken up it sets the country code to X3 and then fails to get a proper link. When I restart airport it sees the network uses GB as the country.
    I can't be the only person with this problem.
