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 PPC :: G4 Won't Startup - How To Restart It

Apr 16, 2012

I have a 2003 17" flatpanel imac (1 GHz)I've been using it for the specific purpose of running some old OS9 software.It's the only way I have to get to some old files.It's been working fine.Then, after a shut down, I cannot get it to restart.Push the power button. Nothing. No sound. Nothing.I've uplugged it for 30 seconds and replugged and tried to restart.Nothing.Is there any other type of power management restart I can try?I have several other newer macs, all running 10.6 or 10.7, which I use for 90% of my work. But this one machine is my only link to these old (OS 9) files which I still need to access.

IMac :: Mouse Freezes After Few Minutes Of Startup

Sep 25, 2010

This is my first Mac user problem posting going back to my original SE! Power PC based imac running leopard 10.5.8 starts up but then mouse freezes after a few mins. Managed to change sleep mode to 15mins - same problem. Can't boot from Disk as same problem, also command+option and shift all still have mouse unmoved! Obvious change of keyboard and mouse have no effect. Could this be related to offspring's addition of ipad plugged into usb a few weeks back? He tends to unplug the device without ejecting!

IMac :: Replaced HD But System Freezes On Startup

Nov 10, 2009

I have a early 09 iMac 2.93Ghz with 6GB of ram. About a month ago it kept freezing at the grey startup screen. I took it to Apple and two trips to Apple later my hard drive was replaced. One month later here I am and the problem is happening again, the same exact problem. I turn on the iMac it goes to the grey screen, the beach ball "like" thing starts spinning and then it freezes in the middle of it and I have to do a hard power off(hold down the power button). Any ideas!? I already scheduled a appointment with Apple tomorrow afternoon but its a royal pain in the a** to keep shuffling my iMac between home and the Apple store. This will be my 4th trip in for the same problem, btw.

IMac (Intel) :: Freezes At White Screen During Startup?

Jun 2, 2014

I was off of my iMac for an hour or two so my screen saver when on.  I went to wake the computer and it was frozen.  I tried using the keyboard and mouse to wake up the computer from the screen saver, but it would not work, so I powered the iMac down manually from the button on the back.  I let it sit for 15 minutes, then I tried to start the computer up again.  Now at start up, I get to a blank white screen with the spinning moving pin wheel, and that is it.

IMac (Intel) :: OS Won't Start But Windows Bootcamp Still Working Fine

Nov 30, 2014

My imac is around 4 years old and has been running both windows bootcamp and os x snow leopard for at least 3 years without any problems. My default operating system is mac and when I tried to turn it on this morning it gets stuck on the white screen with the grey apple icon and the loading icon spinning. Also a bar appears below this that I have never seen before.  I have tried opening the mac in recovery mode but it does not respond and goes to the same logo screen.  

I have tried holding the 'D' key down while the mac comes on and doing the apple hardware test but once the window pops up it does not complete the probing and appears to freeze just before its completion.  I have also tried booting in safemode but the script stops at these commands:

-launch tl: Please convert the following to launchd: etc/mach_init.d/dashboardadvisory.plist

-launch_msg(): socket is not connected 

However, the windows bootcamp is working fine and I can access my mac files from there.Also worth mentioning is that it is not a grey screen that appears on start up it is just the normal apple icon screen.

What does this error message mean? I have had my MBA since Feb, and never had this error. I get the error, in several languages, and the computer is frozen at that point. A restart gets me back up and running until it happens again, usually within; an hour or so. Always while using Safari.

MacBook Pro :: Yosemite Freezes And Restart OS?

Dec 5, 2014

Before two weeks I have done a clean install of OS Yosemite in my MBP retina. 

But unfortunately I have noticed some bugs such as: 

- When I press Shut down the dock stays the half freezed, not completely disappeared and then the system shut down.

- Its a grey screen when I switch on from sleep

- It has completely freezed 3 times and restarts itself

- The wifi signal has been lost 2 times, in my home using my router wlan.

- The continuity doesn't work with my iPhone 6+.

- I don't know but I think that Mavericks were faster.. 

I have done PRAM and SMC reset but nothing.

OS X :: Mac Freezes And Stuck On White Screen On Restart

Jan 2, 2010

I got my IMac 3 years ago just recently started running slower in the past couple months, nothing too bad though. However just yesterday it became unbearable to use. 10 min to start up, once it was on took forever to open up any files etc. So I did some research online and I decided my best option was to reinstall the OS with my startup disk. I did that and erased all my harddrive (nothing important on it.) After doing that it ran great like brand new. Today I turn it on, it continues to work great for a few hours then it freezes in me. I held down the power button to restart. Turned back on and it was stuck on the white apple startup screen. After 15 min I decided to power it off and let it rest a while. After resting it still won't start up.

OS X :: MacBook Pro Screen Freaked Out - Freezes On Restart

Jun 26, 2010

Yesterday I was working away at it when suddenly the screen freaked out, there was blocks of color everywhere and the mouse was acting strange (jerky, up was down, down was up etc etc) I had to hold down power to repair it. When it started loading it froze the little circle in the middle stopped spinning and I had to restart it. Then the same thing happened again froze. So I started it in safe mode then restarted again. This time everything was back to normal. But today again I was just using the computer when everything went all glitchy again and same thing, this time when I went in safe mode the screen darkened and a box in the middle said something was wrong and to restart my computer.

MacBook Pro :: Hot CPU Freezes Its Forcing Hard Restart

Jun 20, 2012

My MacBook Pro early 2011 13" freezes, requiring a hard restart when the CPU temperature stays in the 195 F (as measured by iStat nano) range for more than a few minutes. The fans run appropriately. I am running 16 GB of RAM, most of which is not being used during these 'hot' episodes (according to Activity Monitor). Typically they happen when Mail is trying to connect to iCloud and can't seem to do it. Then the spinning beach ball. Can't force quit or restart from the Apple menu. I'm using 10.7.4 on a dual core i7, 2.7 GHz unit.

MacBook Pro :: Cannot Restart - Freezes On Blank Desktop Background

May 20, 2010

I have a base 15" mbp 2010 model. I wanted to restart my laptop several times and this happened about twice now. I had to force shutdown by holding the power button, but this can't be healthy for it. Here's what happens, I go to apple>restart and then my desktop icons and taskbar, finder bar goes all away so that only my desktop background is showing, and it stays there. I can still move the cursor with my trackpad but me being new to macs, i don't know any keyboard shortcuts to bring up the activity monitor and stuff. Is something wrong with my macbook pro?

OS X :: Macbook Pro Freezes With Msg Restart Computer By Pressing Power Button

Apr 8, 2009

I have a macbook pro, bought it May last year(2008). I don't know much about computers, but I loved the transition between pc and mac, had no trouble with it, loved to work with it, until now. I had noticed it became slower like 3 weeks ago, and a week ago, it started to freeze up on me followed by a message that said please restart your computer by pressing the power button and the screen becomes dark. When I try to restart it again, it takes a while because it shuts down again and again, until the 10th time it works. The store told me to clean intall, which I did yesterday, it seemed to have worked, it was faster for sure, but today it happened again, 3 times! Has this happened to anyone? Does somebody know what to do?

system info:
Dual 1.8GHz PowerPC G5
OS 10.5.6

My computer is 4.5 years old. And every winter for the past 3 years it's had troubles starting up in the cold mornings. Gradually getting worse each winter.

Today wasn't too bad.. it started up on the 2nd try. But on a particularly frosty day it might take 3 goes.

It freezes anywhere between the grey screen to the loading wheel to the desktops appearance.

Sometimes it freezes and gives the message to switch it off by the power button.

On occasion it freezes and shows me this: [URL]

PowerPC :: G5 Freezes During Startup Fan Speeds Up?

Aug 21, 2008

My computer crashed today and hasn't been able to boot back up since. It gets to the grey screen with the Apple logo and stops. The fan then ramps itself up to overdrive.

I've started it up in target disk mode and repaired it using Diskwarrior on my macbook. It had to repair quite a bit and then it showed up on the desktop of the laptop. I can read, write and pull from it. I then ejected the powermac and started it up again to find the same problem persisting.
