I have a Mac Pro and when I put it to sleep, it randomly starts itself back up-sometimes after 2 minutes and sometimes after 3 hours. I've tried repairing permissions, maintenance, etc. and have no clue as to what might be causing this.

I'm having a problem with my PowerBook G4 where is goes into sleep mode at random times. Mostly when I am streaming video..or at times the fan comes on, it sounds super high then boom. sleep mode again. After hitting the space bar, it comes back on, but it'll happen again shortly after. I've played with the sleep settings
View 5 Replies View RelatedAs 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.
I have a G4 533 and up till 3 weeks ago it worked wonderful for a mail server. I have 1.5gb and a 300gb hard drive which has been working wonderful with no conflicts. When restarting after a software update, I noticed on the start up screen that it restarted in "safe mode". I checked for a stuck shift key and of course they were just fine. I thought it might be a heat problem because the next day I started it back up and it started normally so I ran disk utility to make sure. The next time I started, no matter if it was cool or warm, it went straight to "safe mode" just for grins, I backed up all my information onto an external drive and attempted to re-install the 10.4 disk and it went straight to the black "kernel panic" screen. "OK" I said, so I took out the 300gb hard drive all together, installed a freshly "zeroed out" 120gb hard drive that I had and then tried to start it up and it went straight back to the "kernel panic" screen. Next, I not only unplugged the cord but also took out the battery which only then would it start up alright. So now that is the only way that I can get the machine to start up in anything other than "safe mode". At this point, it is a pain in the ass but so far it is working. Does anyone have any idea what I have overlooked or what is wrong? I would really like to use the box but it is just a pain in the a$$ to do this.

Everytime I start up my iMac (2011, 27 inch, OS X 10.7.4 Lion) it starts on what seems to be safe mode. After starting up on safe mode, I restart (not shut down, just restart) again, then it comes back normally.

Every few months, my iMac will start up from sleep mode on its own. Why does it do this, and is it something to be worried about? i am not touching the mouse or keyboard or using any remotely connected devices when this occurs.

After installation update Mac OS Lion 10.7.3, my macbook pro starts allways en safe mode. How can I resolve this ?

A few days ago I updated to Lion 10.7 with which I have had no problem. A day later I installed Moneywiz, Skydrive for mac and did some updates of various software. Since then, if starting from cold, my imac starts in safe mode. I get the start-up sound; then the white screen with Apple logo; then the spinning sun; then the progress bar; then the grey screen with "safe mode" in the top right and user log-in (although I don't have log-in set in my options). Once running in safe mode I can shut-down and re-start; or just re-start and it will load properly. I have tried starting with mouse/keyboard on/off. Is this a Lion thing or what.

My MacBook is making the startup sound but goes straight to a black/dark grey screen. In other words you can see the screen switching on but it's blank. It's in charge mode, has no other external peripherals attached and it's updated to most recent OSX Yosemite.
I only purchased it in May of this year (refurbished). I have tried booting in to safe mode but again the screen remains the same. Â
I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

Second time since yesterday-My MacBook (White-2007) has been stuck in the sleep mode and the only way for me to get out of it was to force shutdown. (Pressed the power button for ~5 seconds.)
The white sleep light had stalled and was not blinking-Is this an indication of software problems, or that my harddrive is about to fail?
My parents just bought a new Imac (3.4 Ghz/I7) which is running 10.6.8. and we cannot figure out why it won't go to sleep automatically. In System Preferences/Engergy Saver we have set both the "computer sleep" and "display sleep" to about 5 minutes, but no matter what we do it keeps showig the screen saver and never goes to sleep. The "put hd to sleep" is checked, and the start screen saver is set to roughly the same amount... I have tried adjusting these settings, to no avail.

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?

I sometimes forgotten to unplug the device before closing the lid. Such as when I'm in a hurry and close the lid of the MBP, only then realize that my iPhone is still attached.
I don't want to put unnecessary stress on the harddrive by it going to sleep, waking up, then sleep again just because that unplugging an USB device woke it up. I notice that this does not happend on my Windows laptop.
And I can hear my Mac Pro waking itself up from sleep every so often. What does this mean?

Whenever I close the lid to my MacBook it'll go to sleep by turning off the harddisk and the light is blinking. But when I go to pick it up or even move it the Superdrive makes a noise as if its searching for a disk and the apple on the lid/monitor blinks on and off. Basically the computer never really stays in sleep mode.
View 24 Replies View RelatedThis is the second time this has happened. I shut my macbook expecting it to go to sleep. I then put it in its booq sleeve and put it in my back pack. About 40 minutes late I pull it out of the case and it is WAY hot and the fan is going like crazy. I open it up and I cant do anything, I think because it is over heated. What is the deal?
