OS X :: Imac Freezes After Sleep

Nov 5, 2009

I recently had a hard drive failure in my imac which i replaced with the the samsung drive listed below and a fresh install of snow leopard. Now i am experiencing a problem when waking my mac from sleep. about 50% of the time when it wakes it will immediately freeze which can only be resolved by a reboot. Could this be caused by this new drive being a "green" drive that conserves more energy when asleep by going into a slower state than a typical drive or is this a software issue?

MacBook Pro :: (2009) Freezes When Trying To Wake From Sleep

Aug 9, 2009

Since the 10.5.8 update my Macbook wont wake from sleep (black screen) and i have restart it with the power button. The Macbook is totally frozen: the keyboard doesnt respond (caps button light wont go on and etc.) and my external monitor wont come on either.What I've tried:

-Install combo update 10.5.8 (i did normal update first time)
-Started up with all the magic keys combos (PRAM and SCM or whatever)
-Tried the fix where you need to (re)enable the ethernet port
-Set sleephibernate mode to 0
- Repaired permissions and disk aid etc.

OS X :: MacBook Freezes Upon Waking Up From Sleep Mode

Feb 2, 2010

Whenever I close my computer to put it to sleep and then open it up later, the computer freezes and I am unable to type in my password to unlock my computer and am forced to hold down the power button until it turns off and then reboot it. This has become a major pain and has only started today but has happened 3 times already. I have an Apple Bluetooth Keyboard and a Magic Mouse connected to my computer and am running 10.6.2 if that helps. I'd rather not have to shut down my computer all the time and I'm no longer covered by any protection.

MacBook Pro :: Freezes After Extended Sleep Time?

Aug 14, 2010

I've been having my MacBook Pro freeze up on me after sleeping for around 20-30 minutes or longer. I open the lid, and it looks fine, then as soon as I try and do something I get the spinning beach ball of death. Then, I click something else, and it instantly gets the beach ball. Eventually I try the dock, which comes up, but then freezes and hangs as well, partially expanded.

Control+Option+Delete does nothing. Nothing at all. Not a single button does anything, the only thing that is responsive at any level is the mouse (now a beach ball), and it only moves. And that's it.

I have no peripherals hooked up, nor is my Safe Sleep mode activated (mode=0).

Power Mac G5 :: Fan Runs On High And Won't Wake From Sleep - It Freezes?

Dec 10, 2007

I have a G5 (Power PC, g5, Dual 1.8 GHZ with 1.25 GB SDRAM, and Mac OS X 10.4.10-phew!) and I recently: added more USB ports using a PCI card, and purchased a non-Apple 22" widescreen display.

Prior to adding USB ports, I was using a hub that ran off its own power source, and used a Samsung 19" monitor.

My situation now: everything starts up fine, but ultimately the fan will kick in at SUPER HIGH and won't stop. I can put my Mac to sleep--which stops the fan noise--but then it won't wake up.

I have run the Apple Hardware test and everything checks out OK. I've also reset the SMU according to directions from this forum; AND I've vacuumed out all the dust bunnies.

The fan runs so loud and so high it sounds like it's an airplane that's about to take off.

Short of bringing in my Mac to a technician, can you recommend anything? My Mac has been glitch free up until now.

OS X :: System Freezes Up While Update / Hard Drive Disapears After Sleep?

Dec 20, 2009

So, I just had the original 300 GB hard drive fail in my aluminum 24" inch Mac running the latest update of Leopard. I wasn't able to save it using diskwarrior (diskwarrior said it was some sort of mechanical failure) but I was able to recover most of the data from it by booting from an external hard-drive.

So I went out and purchased a brand new Western Digital Caviar Black 1TB drive. The install went fine, it found the drive partitioned it and installed Leopard successful. Then is crashed and disappeared when I left it alone to run all the software updates. I came back and the computer was stuck on "Restart Required" after downloading all the updates.

I went to hit restart now, and the system just hanged, wouldn't do anything. So I hard powered down the system and restarted it. It came up with nothing, just stuck on the White Screen of Death. So I plugged the external drive back in and booted from it. Mac OSX couldn't find the drive and diskwarrior would crash if I tried to run it. I tried to boot up from the OSX start-up disk and it couldn't find the drive either.

So I took the case apart and made sure all the connections were solid and the drive was mounted correctly. Everything looked fine so I plugged it in and it started up fine. Finished the updates and the iMac ran great. So I thought maybe it was overheating, so I've installed smcfancontrol and started to monitor the temp of the drive. I also took the mac apart again and sucked out any dust in the fans or vents. The drive never goes over a 105 F, so it doesn't seem to be overheating.

However, this is where the problem is consistent: everytime the iMac goes into sleep mode, it crashes and the iMac is unable to find the hard-drive again. Unless I unplug it completely for 5 minutes or so. Once I unplug it, it finds the drive and operates like a champ.

MacBook Pro :: Freezes Randomly And Beeps When Coming Out Of Power Down Sleep

Jun 27, 2014

So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3.  

The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.

I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests. 

At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower).

IMac :: IMac Freezes When Connecting External Monitor?

Apr 8, 2008

I have a newer iMac 24" bought in 11/2007. I have the mini-dvi to vga converter and when I connect it to a external tv capable of 1024x768, the iMac freezes and does nothing. I disconnect and the screen turns blue and the flickers back on and everything works. I have made the connection then booted up, and I have tried every resolution all the way down to 640x480, same thing it just locks up the screen, but again as soon as I unplug the mini-dvi to vga cable from the iMac it flicks to a blue screen and everything comes back. I have reviewed dmesg nothing, and revieiw /var/log/messages. Is there any troubleshooting I can do. I am old school unix/linux guy just converted my family to Apple and would like to use the display on my tv to watch my iTunes movies.

MacBook Pro :: Mouse "freezes" After Sleep/reboot

May 21, 2012

After putting my MacBook Pro to sleep or rebooting, the mouse does not work anymore. I can move the mouse pointer, but can't left-click.

It seems as OS X senses a "left mouse button pressed" condition the whole time, when I wake the MacBook an move the pointer, I continuously draw selections on the screen, as if I pressed the left button and moved the pointer.

The only thing that helps is a Cmd + alt + P + R reboot, then the funtionality is fully restored, but after putting it to sleep or rebooting normally, the problem's back everytime. It's not a trackpad issue, connecting a USB mouse results in the same symptoms. I also did an SMC reset (removed battery and pressed power button 5 sec) I travel a lot with my MAcBook and have to do a hard reboot everytime when using it.

IMac :: New 27" Imac Takes Ages To Go To Sleep?

Aug 15, 2010

just purchased a new 27" Quad core i5 and it takes about 5 seconds for it to go to sleep, and then makes a loud noise after.

My hard drive is also noisy, it whines and drums constantly.

I also have got yellow tint on all sides of the screen.

I live in NZ so if i will not get a new replacement, instead it will be sent away to apple which will take forever

by the way it is the older 27" (late 2009) version.

OS X :: IMac Freezes On Restart

Jan 6, 2011

I have a 3.06 Intel Core 2 Duo iMac with Snow Leopard. It is completely up-to-date and has always ran beautifully. I have not installed any new programs lately. Recently, when I go to APPLE > Restart (maybe after an update or just because I like to restart my computer on occasion) the bar at the top disappears, my dock stays up on the screen, and the computer just sits there and freezes up on me. I am forced to hold down the button on the back to get my computer back. Here are the things I have tried:Re-install of the latest update using Combo Update Reset PRAM Repaired Permissions Booted from disk and ran a Repair Disk Complete zero-out of the HD, clean install of Snow Leopard, and reinstallation of everything from a Time Machine backup Nothing has worked...The other problem is that it only happens when my computer is on for several days. If I restart daily, it doesn't happen. So, it makes it hard for me to log-in as a different user for that long to initiate the problem. I think it has something to do with a program that I may open and close throughout the week but I have no way to pinpoint what program it is.

IMac Freezes When Do A Shut Down

Mar 23, 2012

My iMac won't shut down completely any more.It gets to a white screen and then freezes, and I have to hold down the power button to get it to shut down.I have also been getting intermittent kernel panics, maybe one every 3 or 4 days.I went through all of the troubleshooting steps to try and figure out the cause, with no luck.Did a new install of Lion and everything seemed OK for a few days, and then started having problems with programs not responding, not being able to shut down, and now getting kernel panics again.Considering completly formatting the drive and starting fresh with everything, but not sure if that would solve the problem either.

IMac :: Intel Freezes Up Constantly

Feb 6, 2009

Having some trouble with my iMac5,1 - Intel Core 2 Duo - 2.16 GHz. It's about 2yrs old. Symptoms include: 1 - freezing when I open, close or move windows too quickly, open too many windows and/or when I multi-task in general. Anything processor intensive is unreliable. 2 - apple mouse cursor shoots off to the side of the screen for no apparent reason and scroll button is unreliable. 3 - lines across the screen that resemble pixel drop-outs - they come and go. I'm still running 10.4. I've wiped out my hard drive twice in the last 2 months and started over from scratch. When I re-install 10.4.0, it seems to run fine. until I run the system updates. That's when my trouble begins again. I've also cleared out my caches and histories repeatedly. I've run the Disk Utility repeatedly. This is getting serious. My PC at work is WAY more reliable than my Mac. I'm considering switching back! I owned a G4 for 7 years and was very happy with it. Was the switch to Intel a bad idea?

IMac :: Not Freezes - Wifi Related?

Apr 26, 2009

So I've had my iMac about a week now. I started a thread about not having any freezes. Well this weekend I experienced two. Both of which occurred while using iTunes (once while importing my old library into iTunes from an external USB drive, and once just having iTunes open). Not much rhyme or reason to the freezes nothing in the crash logs. This is slightly depressing, since the replacements people are getting seem to freeze as well. I still don't think this is Wi-Fi related. I just think there's a serious conflict between the ATI 4850 chip and the rest of the hardware. This is pretty much unacceptable for a new machine.

Right now I'm saving for the 20" model (2.66). Would The 20" 2.66 iMac Freeze Like The 4850 Issue? Will it freeze like the upper model with wi-fi on? Making sure before I invest in an iMac.

IMac :: Freezes After 15 Minutes Of Being On - Overheating?

Aug 21, 2009

My Imac freezes up a lot, usually after 10 to 15 minutes of being on. I suspect it has something to do with overheating. I have to get my data off of the drive before I take it into the Apple store for fear that they will will just replace the drive and all will be lost. I have a fan blowing on it now in the back and am copying data onto an external drive little by little until it freezes up.

I bought it last fall and have a 3 year warranty on it and this will be my second time bringing it in for repair. The first time it was a problem right out of the box when I brought it home and it was replaced. It's a 3.06 processor, 24 inch screen. I am not impressed by the hardware reliability and the all in one system. I am regretting buying the imac after being a PC user for so long and I am using my Windows PC to write this. I suspect the cooling system could be better on my IMAC given the compressed footprint.

OS X :: Intel Imac Won't Boot Up And Is Freezes When It Does?

Jan 7, 2010

I was working with logic pro 8 on a project when the APP crashed. Then, the whole computer became real slow. I couldn't open anything without getting the spiraling rainbow circle for at least 3+min and even then the app wouldn't launch. So I shut down normally, which took a while.

After I left it off for about a min or so, I tried to boot again just to get stuck on the gray screen with the apple logo. I did some research on my phone (since I currently don't have internet because I'm moving this week) and found out how to reset the pram. I tried it, and this time it got all the way to the blue screen where it got stuck. I tried resetting the pram a second time to finally get to the log in screen but everything was going very very slow. Unusable type of slow. Opening a new finder window took at least 2 mins and everytime I ran my mouse across the idock, it would freeze.
