OS X Yosemite :: Power Reset Required After Sleep
Dec 9, 2014
Often when I put my iMac to sleep in the evening I find the system unresponsive when I come to use it the next day. I can see instantly that the system has an issue because I see that the screen backlight is on. The system does not react to any mouse or keyboard input and requires a power off reset to restart.Â
I thought that the issue may involve Parallels which is often running when I have this issue , however, I have spoken with Parallels support who recommended removing parallels, repairing the disk permissions and reinstalling Parallels which appears to have had no effect.Â
The iMac is very new and was purchased in November 2014 and is configured with a 3.5GHz i7 processor, 16GB or RAM 3TB HD and NVIDEA 980 graphics card.Â
Info:
iMac (27-inch, Late 2013), OS X Yosemite (10.10.1)

My MacBook Pro 13" (Mid 2010) doesn't go to sleep, when I close the lid or when I try to activate sleep under the Apple menu. I haven't changed nothing in the system preferences. I already tried the following:Â unplugged all USB devices plugged and unplugged external display closed all applications (except of Finder of course) resetted all energy saving preferences deactivated bluetooth checked share options (everything is deactivated)Â
Then I unplugged it from the power supply and after I closed the lid, it went to sleep. Then plugged in power supply again and sleep didn't work.

iMac 27 locking up after sleep mode requiring full power shut down and rebooting in safe mode then shutting down and rebooting normally.. Permissions and this check show no errors, the only error sleep mode failure. Boot up is very slow as well as wake up when possible is slow. Yosemite seems to need a new release in order to correct the boot problems. System operates more like a Windows machine than Apple machine what's going on?

It's happened twice this month - my CPU fans will suddenly rev up to 4,000 RPM, and iStatPro will show the CPU temperature as "--". The first time it happened, I was worried that the machine got too hot. The second time, I had just sat down at the computer in the morning... the top of it was hardly even warm.
Both times, after shutting down and rebooting the fans went back to normal, but the computer performed poorly in graphical tasks such as rendering and gaming until I do an SMC reset, which brings it back to normal.

I have the problem that I need to frequently power cycle (shut off and on) my dsl modem to maintain a reasonable speed with my internet connection. It is making the internet experience pretty user unfriendly. Does any one know whether there is a way to optimize my internet connection such that this is not required so frequently (couple times a day)? I am on my second dsl modem, and the same problem has occurred with each of them. ATT simply advises me that my solution is to power cycle the modem to sync the system, whatever that means.

I can't figure out why my MPB frezzes up all the time. It's currently running worse then my Win XP. I counldn't even finish this thread before it frooze up again. I tried to run a disk check, that also made it frezze. The only way i can get it to life again is a hard reset.

I had hooked up the MBA SuperDrive and wanted to see, just for fun, whether the machine could boot from a Knoppix DVD. (Knoppix is a Linux distribution that can run straight off the DVD without touching the harddisk.)
I tried and it seemed to work fine, until I got stuck on a blank screen. Oh well.
I switched off the MBA by holding the power button for >4 secs and it shut down. Rebooted, and noticed that the SuperDrive didn't make any noise. Once in OS X, I didn't get an icon for the DVD. Hmm. Hitting 'eject' didn't do anything.

MacPro 12 Core is going into sleep mode (so it seems) and becomes unresponsive requiring a hard reboot by holding the power button. Did this on a new user account I created, then it did it in Recovery Mode while using Disk Utility to repair the drives. I was about to try reinstalling OS X but it seems that this maybe a hardware problem if it happened in Recovery mode. Is my thinking right, or could it still be software? Trying to run Hardware test (D on startup) but can't get it to work so far.

I keep getting a small triangle next to my e-mail inbox that indicates that I can't receive e-mail unless I accept an insecure authentication, checked in advanced in mail preferences. This problem seems to have arrived with my upgrade to Yosemite and it is causing e-mail from my family to be rejected and returned.

a MacBook Pro, Retina, mid 2012 running Yosemite 10.10.1...I've noticed that since upgrading to Yosemite, if I close the lid on my computer to put it to sleep and then leave it overnight, it is completely drained by morning. It used to burn through, MAYBE 5% overnight. All the power settings are set for no power usage, i.e., no power nap, no wake for network, etc. If I look in the system log, I see something that happens every hour while it's asleep. I've included an excerpt below.Â

I made a change to my spam setting (move spam to spam folder) and since then my mail quits everytime I start it up. I'm even able to get to the preference for it but it just quits.
The resolutions offered here are complicated.
Is there a way to just RESET mail? Or even re-install the OS?

I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.Unfortunately my cats like to touch the keyboard, thus waking up my Mac.Is it possible to wake the mac only by pressing the power button?

I was working on my computer last night and stepped away. The battery ended up draining all the way. I pluged it back in and couldnot get it to restart. So I left it plugged in all night to recharge the battery. Woke up this morning to a full battery tried to turn it on but nothing happens except the sleep mode light turns on. Black screen and no functions. Pulled the battery to reset it still nothing. Put in a cd to see if it would wake up still nothing.

I'm running OS X 10.10.1 on a 2010 Mac Pro with a Bose Companion 5 USB sound system. Everything works great and as expected except when I restart the Mac Pro. The sound settings switch off the Bose speakers and reverts back to the internal speakers of the computer. I have to go in everytime and reset it back to the Bose sound system. I never had this problem using Mavericks.Â

Starting a couple of days ago, my 2009 iMac won't sleep. I created another user and when that user is logged in sleep is working fine. This leads me to suspect that some of the user settings are clobbered and I need to reset them to get things normal again without having to reload the system. Can someone tell me what files I need to trash to get my user settings wiped out? Alternatively I could always do a fresh reload of the system and then just recover my last Time Machine backup of my applications but NOT recover my settings.

Today I noticed that my mid 2010 MBP is not automatically sleeping. I ran Apple's extended hardware test, along with TechTools Pro 5 from AppleCare disk. Both passed. Reset the SMC and PRAM. I'm still not able to auto sleep. Is there a way to see what exactly is causing my computer to not automatically sleep? Console messages or something?

When I run my macbook pros Battery down, there comes the low battery warning. After a while the system just goes down without suspending anything to my harddisk. When I restart my computer it does a normal start and after logging in I'm experiencing a lot messages due to the reset time. I correct my system-time and restart my mac and the system is back to normal.
Usually I'd say: Replace your CMOS-Battery (I know I have an EFI-Firmware), but where is it?. Or in other words: Is there a "System"-Battery, that would prevent my mac from forgetting the time?
Since I'm not running down my battery to 0 very often I only experience this issue from time to time and never took time to do anything about it.
iStats battery-Status says: Health:83%, Cycles:333, charge 50%...

I have tried two different brands of blank CDR in my drive and both times, they fail to mount and in Disk Utility, show up as Sony DVDs (neither of them is a Sony or a DVD), but not writable. I have no problem with media that already has content. I've tried resetting PRAM, but nothing else yet.

On my old iMac with OS X 10.4.11 I forgot my admin password. I have the installation DVD, but it doesn't work like the Mac Support instructions seem to indicate. When I install the Mac OSX 10.4 DVD and choose utilities to change password, the only change password option is for the DVD itself...no icon for the associated iMac hard drive. I believe I'd be changing/using a root password rather than the Account Admin Password that I need to change. How can I get out of this situation and identify a replacement for the forgotten admin password on my Admin Account?

I've checked with the seller to confirm the password and I'm sure of caps and spelling.Â
Can I reset the passworde without an install DVD?Â

My macbook pro keeps going to sleep and sometimes it won't wake up.. or the screen flicker between sleep and awake. I've done all the hardware tests and it says everything is in working condition. Sometimes it works perfectly all day and sometimes it doesn't.. I've reset the PRAM and NVRAM and that doesn't seem to fix the issue.. (I have a video I filmed with my iphone of the problem but I can't add it). My MacBook Pro is barely a year old. Â

I have this iMac for slightly over two years and when I forst got it I thought it would be a good idea to have it start up a 6:55am each weeday. After about a week I changed my mind and went back into Power Saver and turned off the settings. Since then, I can't tget the machine to quit auto-starting at 6:55, 7:55 and even sometime 8:55. I have called Apple, taken it in to an Apple store, they even claim to have replaced the computer

My date and time resets each time my mac sleeps or is reset or if I open date and time options. It keeps sending emails of my old reminders from 2008/2009 from ical and my to-do list emails me its reminders. This happens every time I open my comp or even just open date and time options. I also get the ical reminder notification that pops up freezes on my screen. Not sure how this happened, but can anyone help?
