Dec 7, 2014

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?

OS X :: Uninterruptible Power Supply (UPS) - IMac And Sleep Mode?

Jul 22, 2009

First, sorry for the longer post - I have to explain everything. I just bought a 24-inch iMac, Mac OS X 10.5.7, 2.66 GHz Intel Core 2 Duo, 4GB, 1067 MHz DDR3. I also just bought an uninterruptible power supply (UPS) from CyberPower. Everything's great, but I still have this one question which is bugging me. What happens when my iMac is in sleep mode and the power goes out? I have set the settings so that my iMac shuts down after 10 minutes of "battery" (UPS) usage, but I am not sure if it will do that when in sleep mode? The UPS is connected to my iMac via USB cable so that they communicate to each other in the case of the power outage, etc. This is what somebody wrote elsewhere on this topic: "Using the Deep Sleep widget, I've worked around this issue: I changed the default sleep behavior to Safe Sleep (hibernation+sleep).When I'm on the grid, my computer will now safe sleep after 3 hours of non-use. If I go off the grid and onto UPS while the MP is awake, the Energy Saver preferences will safe sleep after 1 minute. If for some reason this doesn't occur, Energy Saver will invoke a shut down after 5 minutes. If I go off the grid and onto UPS while the MP is safe sleeping, no big deal since contents are written to the HDD and RAM with this configuration."

I've downloaded the Deep Sleep widget and am using it now. Obviously, the user up there is using a MacPro, and not an iMac, but it should work the same. So, I am not concerned about losing data, and blah, blah, blah... what I am most concerned about is my iMac not working properly because it wasn't shut down properly. I know that there is a very low risk of this happening, but I've spent big bucks on this iMac and I want to make sure that it is shut down properly 100% of the time, if I can help it. If my iMac loses power when in deep sleep, will it be ok? Obviously, I am still using the UPS in deep sleep, but that UPS (battery) power will not last long and will shut down. I am going to turn my iMac off when I don't plan on using it for several days, but if I'm just out and about and the power goes out and my iMac is in deep sleep, will it be ok with the power going off? I contacted CyberPower and this is what they had to say after a long back-and-forth. "You will want to use the deepsleep tool. I had the belief that sleep was the same as windows hibernation where everything is saved to disk. Since deepsleep will save to the hard disk, you would not lose anything when the power is lost when the battery runs out." Despite all of this, I wanted to hear what everyone else thinks about this, especially those of you who might have experience with this kind of stuff. What do the rest of you do when it comes to UPS, etc.?

OS X :: Why Does My G-5 Shut Down My Computer In Sleep Mode

Nov 14, 2008

Could someone please explain to me why my computer is shutting down in sleep-mode. In addition, when it happens, the fan goes into hyperblow, which doesn't make sense because it would not be operating if the system were completely shut down. It acts like it is shut down but won't respond or wake up, etc. I re-loaded my system software per the Mac Store Genius' advice, but that didn't work. Is it possible that my power supply is going?

OS X Yosemite :: (10.10.1) IMac Locking Up Suddenly When Using Safari

Dec 10, 2014

I have a 4-year old Mac and have noticed lately that it freezes up when I am using Safari.  I'll be on a website and all of a sudden, it just freezes. The only way I can fix the problem is to manually turn off the computer and restart it again.  Nothing works - unable to use the force quit command or the dock to close Safari. Why this might be happening, or if there's another way to deal with it when it happens besides turning off the computer?

MacBook Pro :: Double Tap Restarting After Sleep Mode / Restart / Shut Down

Oct 23, 2010

so i've been having an issue with the double tap to hi-light any text i wish to copy. Such things as double tapping the URL bar to hi-light the whole url so i can just retype w/e site i want to go to. Every time i restart or turn off or my mbp goes to sleep and i reopen it, the double tap function resets. So i'm forced to go to the system preferences > trackpad> "double-click speed" to slowest in order to get my double tap to hi-light anything again. Is there something wrong with my mbp? Or is there a way i can save the settings when i put the double-click speed to slow so that it wont reset every time my mbp needs to be woken up or restarted?

MacBook :: Laptop Holds Charge Only In Sleep Mode / Shut Down

Jul 3, 2010

I tried SMC resets and everything. The Macbook takes a charge and charges normally when it is asleep, or off. It will charge to the max (96%). Battery has 349h load cycles. Charges when asleep or off. As soon as I power on the laptop or wake it up, it will stop charging. Battery holds the normal charge I usually get (3ish hours). Tried a few pram and smc zaps. Battery charger is a Hong Kong knockoff. Battery inside is genuine. 2008 Aluminum Macbook. Cleaned magsafe and port with q-tip and still to no avail.

When plugged in, it will run *off the battery* and the charger will show a green light and not trickle charge the battery. It will drain the battery, and then when it is drained it will run off the power. Check the screen shot. I am thinking that the charger is the culprit. Because it holds a charge when I let it charge while it is off. It will charge up just fine, in the two hours or whatever it takes to charge itself up. Battery usage is normal when it is running off the battery.

OS X Yosemite :: Title Bar In Full Screen Mode When Using Certain Apps

Dec 2, 2014

When using certain apps in fullscreen hovering the mouse over the top of the screen produces the menu bar, AND a title bar which is interfering with screen real estate. 

How do I remove it? 

The screenshot below is with a youtube video playing in fullscreen, and the menu bar popped down.

The title bar saying "Safari" and with the green button is the one I want removed. This title bar seems to pop down in Java and Flash apps, and it's particularly irritating when the pop-down steals screen real-estate (photoshop, bitwig, Flas-player, etc.). Ideally I would like to stop the menu bar from popping down as well but it doesn't seem possible.

MacBook :: Wakes From Sleep When Power Connected And Lid Shut?

Oct 3, 2009

My macbook has developed a problem where when the lid is shut and the power is connected it wakes up from sleep and then goes back to sleep and repeats this process every 30-60 seconds.

What's weird is it doesn't wake from sleep and get stuck in this loop when�the lid is open and the power is connected and I select sleep from the Apple menu�when the lid is shut and the power is NOT connected and is running from the battery

I recently updated my mac to Snow Leopard and put in a new HDD and since doing so the problem has been occurring.

OS X Yosemite :: Keyboard / Trackpad Stop Working After Sleep Mode?

Dec 3, 2014

After a few hours of uptime, certain keys on my keyboard stop working and I have to reboot: both command keys and the zero key. Sometimes, after the computer has been in sleep a long time, the keyboard and mouse don't respond at all. I can get the computer to wake up again by pressing the power key, but the mouse and keyboard don't respond, so I can't do anything except hard boot.  This problem first appeared after the update to 10.10.1. (I'm dealing with it right now, so I'm getting the '0' through the keyboard viewer, but there's no way to access that from the password screen.)

Power Mac G5 :: No Sleep Mode Running OS 10.4

Nov 23, 2007

My old G5 dual 1.6 will not go into sleep mode. I had upgraded to 10.5 but several of my photography programs would not run so I reverted back to 10.4 by reinstalling the operating system and not wiping the drive clean. I now must shut down everytime or the G5 will get to the point that all of the cooling fans are running full speed and it will not go into sleep mode automatically. Any suggestions other than a clean install?

OS X :: Power Mac - Installed Leopard - No Sleep Mode

Nov 9, 2007

after having installed Leopard, my Mac doesn't go to sleep anymore. When I activate the sleep mode, it begins to "shut down" and the fans begin to blow. Normally, shortly afterwards it would sleep, but now the fans blow and blow and blow and nothing more happens. Using the mouse wakes the Mac again.

Power Mac G5 :: Wake Up From Sleep Mode Causing Crashes

Oct 20, 2007

I've been fighting bad sleep crashes for over a year. Sometimes it would freeze when it started sleep, sometimes when trying to wake from a sleep. I've spent countless hours researching the problem, reading everything on the boards. I tried resetting the PMU, turning off Bluetooth, removing all USB, and all of the other suggestions. Nothing alleviated the problem. Last week I replaced the lithium battery on the mother board because it wasn't keeping the correct time. So far it is sleeping and waking perfectly for the first time in ages. No more freezes or jet engine fans. I have my fingers crossed. Power Mac G5 dual 2 GHz, purchased June, 2003

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. 

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. 

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.

Hardware :: Power Mac G5 Will Not Wake From Sleep / Fans Blowing Full Blast

Oct 9, 2005

I just bought a new dual 2.0 ghz power mac G5 about 2 weeks ago. I set everything up and dowloaded all the updates for everything, and then about a week into using it the problem started. I left for work and when I got home that evening after the computer had been asleep all day, it sounded like the computer was taking off from a runway. It would not respond at all to the keyboard or mouse so I had to shut it down by holding the power button on the front of the unit and then start it back up. I called tech support but they had me turn the option off that puts the harddrive to sleep when possible and then turn off my screensaver. Well it was fine again for about a week and then it happened agin yesterday, not once but twice. I looked on apple discussion boards and there is alot of this happening. Well I took one guy's advice that seemed to know what he was talking about. I restarted holding the command-option-o-f keys down, then prompted the computer to reset the v-ram, and two other things he suggested to reset that I cannot remember. Then I restarted, trashed the energy saver prefs and ran a repair disk permissions task inside OSX. Well that is where I am now, and it has not done it again, but I am still trying to find out what exactly is going on here. I just spent $2000 on a machine and it appears messed up and Mac has no answer.

IMac (Intel) :: Fan Runs Full Speed On Shut Down

Aug 27, 2014

My iMac runs perfectly fine; more or less as it did when it was new. In OS X, when I shut down the computer, the fan runs at full speed indefinitely, unless I unplug it or boot back up.  When running, the fan is perfectly normal (increases speed a bit when doing something taxing).  I've never heard it at full speed before until this started happening.  After following the SMC reset procedure with no luck (I'd like to add that the SMC reset only says it relates to fan problems when the computer is ON), I searched a bit and noticed there are one or two cases where a problem like mine was believed to be a motherboard issue, and therefore a costly fix. 

However, here's the fun part. When booted into Windows 8.1, shutting down the iMac does not cause this issue to occur.  It stays silent, as it should, even if I disconnect then reconnect the power.  This leads me to believe it's unlikely to be a motherboard issue.  However I've wiped, restored, and reinstalled fresh copies of Mountain Lion, Mavericks, and Windows 8.1, and the result is still the same: if I don't want to have to unplug it from the wall, then I have to use Windows to shut it down. 

So then, my questions are these:

-What is the difference between shutting down from OS X and shutting down from Windows?

-Is an operating system allowed/able to touch BIOS settings?

-Is it possible to still be a hardware problem, given this difference? 

My default OS is OS X, and it makes no difference if I change that to Windows.  I also did a PRAM reset, even though that has nothing to do with fans...

iMac, OS X Mavericks (10.9.4)

Software :: System Not Exiting Sleep Mode / Kicks Back Into Sleep Mode

Dec 29, 2009

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.

The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.

How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

MacBook :: Sleep Doesn't Work With Connected Power Adapter Under Yosemite 10.10.1

Nov 30, 2014

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: 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) 

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.
