MacBook Pro :: Spontaneously Reboots - System First Freezes For Roughly 30 Seconds
Dec 1, 2014
I have a mid-2010 Macbook Pro with a 2.53 GHz Core i5 processor and 8 GB of RAM, running OS X 10.10.1. For the last few weeks, at apparently-random intervals, the machine has been rebooting while I've been using it. I can't tie this to anything in particular that I'm doing. It may go a couple of days before a restart, or it could be like today, where it's happened five times in the last four hours. I've tried resetting the PRAM and the SMC without apparent effect.Â
When the reboot happens, the system first freezes for roughly 30 seconds--the mouse pointer won't move, it's unresponsive to keyboard input, etc. The system then appears to power down--the screen and external monitor go dark, fans stop, keyboard backlight goes out. A few seconds later, it powers up, gives the boot chime, and goes through the normal boot sequence. At no point does it give the "your computer was restarted because of a problem" message, and I don't see anything in the Console app that looks like a kernel panic.Â
About two years ago, the logic board was replaced to address a somewhat-similar issue--the system had been freezing and could only be recovered by a hard power off (holding down the power button for several seconds). Â
I'm not sure where to start looking for the cause of this problem, since I can't figure out anything in common with the circumstances surrounding the reboots.

MacBook Pro (15-inch Mid 2010), OS X Yosemite (10.10.1)
So my Macbook pro started to stall for 10 seconds or so every few minutes beginning yesterday. Like I am just surfing the net, and it freezes completely for 10 seconds, than everything is back to normal. I don't know what to do to remedy the problem. I have Applecare so I could send it in, but wondering first if anyone has had this problem and knows a quick fix before I send it in.
My MacBook was working perfectly until a couple days ago, when it suddenly started hanging every time I booted it up. I gave it a day, and managed to complete some software updates the next time I logged in, after which it started working fine again. Now, however, it KEEPS freezing every ten seconds no matter what I'm doing. The worst part is, it freezes for about five seconds (the pointer becomes a pinwheel, which keeps rotating, as if my laptop's processing something), and then it starts working again. I ran a virus scan to no avail, and have rebooted my MacBook countless times. I don't know what's wrong with my laptop
On my 1st Gen Mac Pro, I suddenly get a strange blue screen out of no where. Everything on the screen freezes for a few seconds then the screen flashes blue for another few seconds. After the screen comes back from the blue, everything works perfectly again. Even when listening to music, music pauses for a few seconds and then comes back. This happens a couple times a week and its getting on my nerves. Sometimes it lasts for a long time and requires a hard restart.
I have tried reinstalling Leopard/tried hardware test/upgraded to the 8800GT video card and the 3870/I cleaned the whole inside of the box with compressed air. I even took her into the apple store and had a genius look at it over night. They told me everything is working perfectly. Ofcourse it started doing it again after I got home with it. The apple store suggested that I could always replace the logic board but they want over $1000.00 for that and I dont know if its worth it.
My MBP (2007 intel) freezes or spontaneously shuts down and crackling comes from the speakers. Sometimes this happens together all at once? It happens with and without peripherals.It does not seem to be linked to a specific program or peripheral use.Â
I need the thoughts and advice from your seasoned Mac people - I have 2 MBP's - 1 15" aluminum, one last years model 17" Unibody (with Black around screen). The 15 has run great since day one. The 17" was ok, but now is locking up and causing me to reboot, fans seem to run on high all the time, and it is very slow to react while using the OS, it gets worse until it locks up. I have upgrade to Snow Leopard thinking that that might fix it, but it has not.
When I got it, I restored from the back up of my 15" using carbon copy cloner. I only imported users and data such as pictures and music. Do you guys think that this is a hardware issue or a or should I back all my stuff up and then blow everything away and reinstall from the ground up with a fresh SL install?
When I called apple they tried to sell me apple care and told me that it was out of the full warranty and if I send it I would to pay for what was not under warranty. SO I am hoping that someone has seen this and has a fix that I can do without having to take it in.
When I am using Google image search in Safari, my MacBook freezes for about 20-30 seconds before it shows the results. It just shows me grey boxes in the beginning and loads for a long time. I had the same issue with my old MBPro, but also with my beand-new one.

I am a total newbie to MAC's and made the plunge and got a MacBook Pro 15 inch with built in camera...
I am trying to run Skype or iChat and the video in preview mode freezes after it initially starts in both programs. I tried to reboot but the same result is happening...
its a PC and i know this is a mac only forum but i dont have the time to sign up for another forum. anyways, i boot the pc, it brings me to a menu where it has the options to boot in safe mode, boot normally, etc. i choose boot windows normally and it starts to load windows, however, it freezes about 5-10 seconds into the loading screen and it brings me back to the same boot menu. idk what to do!
I have an Early 2008 Mac Pro 3.2 GHz dual CPU (8 Cores in total) one day I started the system as usual and the system start till the Apple Gray Logo appears and then it reboots and keep doing this in (loop)
I started the Apple Hardware Diagnose and it hangs in the middle! the Apple Authorized shop/repair people told me (after the tried to fix it) it is mostly the Logic Board
Can it be the RAM or the CPUs? my mac is out of warranty and the cost to fix it is crazy! so I was thinking I can buy the parts and replace it my self.
Recently my macbook (running snow leopard) has started disconnecting from wifi after about half an hour, this is getting really frustrating, how can i stop it?
I recently took the plunge and installed Lion after being content with Snow Leopard....well now I have quite a few issues. When I open system preferences for some reason it automatically opens to Network...why I'm not sure. When I click show all, then click sharing, I can't make any changes in the Sharing preferences without my entire system locking up. I can't force quit or anything. I can still use the mouse but all I have is the rainbow wheel!
I have searched and searched and haven't been able to fix it. I have tried booting into the Guest account and the same problem happens there. I have trashed all the plist files everyone says to try. I have tried repairing permissions etc. I feel like I have tried everything. Is there anything else that I can do without have to do a clean re-install. I'm hearing if I do this that I won't be able to migrate my files from by backups due to permission problems?
I also took a look at my system log and it is full of this! Jul 3 22:24:26 jessica-imac com.apple.launchd[1] (com.apple.Kerberos.digest-service[1307]): Exited with code: 1 Jul 3 22:24:26 jessica-imac com.apple.launchd[1] (com.apple.Kerberos.digest-service): Throttling respawn: Will start in 10 seconds .....
I just realized today that there are entries made in System.log (visible in Console) every 10 seconds. They are trying to run a MOTULauncher, which is probably some type of driver for a recording device I installed at one point but no longer use. Here are the entries in the log (the same repeats every 10 seconds):
4/22/09 1:14:53 AM com.apple.launchd[68] (com.motu.MOTULauncher[7164]) posix_spawnp("/System/Library/Extensions/MOTUFireWireAudio.kext/Contents/MacOS/MOTUFireWireConsoleLauncher.app/Contents/MacOS/MOTUFireWireConsoleLauncher", ...): No such file or directory 4/22/09 1:14:53 AM com.apple.launchd[68] (com.motu.MOTULauncher[7164]) Exited with exit code: 1 4/22/09 1:14:53 AM com.apple.launchd[68] (com.motu.MOTULauncher) Throttling respawn: Will start in 10 seconds 4/22/09 1:15:03 AM com.apple.launchd[68] (com.motu.MOTULauncher[7165]) posix_spawnp("/System/Library/Extensions/MOTUFireWireAudio.kext/Contents/MacOS/MOTUFireWireConsoleLauncher.app/Contents/MacOS/MOTUFireWireConsoleLauncher", ...): No such file or directory 4/22/09 1:15:03 AM com.apple.launchd[68] (com.motu.MOTULauncher[7165]) Exited with exit code: 1 4/22/09 1:15:03 AM com.apple.launchd[68] (com.motu.MOTULauncher) Throttling respawn: Will start in 10 seconds
How to go about stopping this? I've been searching on my computer trying to find a configuration file or something, but I can't seem to find where this is being called.
I have a Lyon Server and I see on the system log every 10 seconds a crash of a process I cannot (yet) identify.I would like to upload a log but I do not see any upload possibility - so I pasted this here below. Furthermore the computer does not witch into the sleep mode.. [code]

Say an app has crashed and I then bring up the force quit dialog. I then select the app I want to kill, and press the force quit button. Now as the little popup that says "Are you sure you want to force quit" is coming down, my machine freezes. This has happened 3 times exactly the same way. Other than that, the machine is smooth as clockwork. I'm kinda thinking there is some sort of GFX card bug or something?
During the first months of owning my new 15-inch MBP, I had at least three freezes. I remember there being a huge thread about this, which I can't find now. Happily though, my MBP no longer freezes, but I haven't done anything to it (other than software updates). So, was it a software glitch? Everyone were shouting about some sort of controller chip or something before, if I remember correctly...
My dads MacBook Pro started acting weird first the screen would freeze up and the cursor could still move but there would be about an inch wide black line that would follow on top of the cursor wherever you moved it.
We thought it was a software problem so we booted it up off an external drive and it did the same thing after a few seconds of loading the finder, now it won't even boot, it loads the white screen with the apple, then it stops at the blue screen where it usually shows the loading of everything, once in a while it will get past that but it freezes with black lines over the cursor.
I've tried zapping the pram and i've held the power button down till it beeps i've also reset the pmu, so im out of ideas.
My MacBook Pro freezes when attempting to access System Preferences. I am able to Force Quit but that's it. Screen went black for about 30 seconds earlier tonight. Never had a problem before a previous update.

recently my mac pro has been randomly freezing then all 3 of my screens go blue for 5 seconds, then everything is back to normal. This happened 2 months ago, and eventually my graphic card died. I dont know whats causing this, I have tried different cards so i no its not hardware. Anyone have this happen? Any fixes?
i bought a wireless myghty mouse froma friend for 15 dllsi was alsmot new he only used once or twice he even gave the box with the cd's which i dont need right? i have leopard 10.5.6 with the newest updates and a umb and for some reason sometimes when i close my macbook and turn off the mouse an try to open my laptop he macbook freezes and the screen wont even turn on and i close it and i see the little light turn on and off and open and nothing i have to turn it off the hard way a then i turn it on and says i dont have the bluetooth adaptor or hardware and i have to turn it off 2 times
I am having some trouble with my MBP early 2011. It's currently running 10.7.3. I have been trying to open system preferences to modify some things, but it freezes whenever I enable editing. System Preferences has been crashing at any point that I have to enter an Admin password. I noticed that this just started happening recently, and I would really not like to reinstall Lion, as my internet will take it 3-4 days to download.
I noticed that this problem arose after I tried to remove MySQL Community Server for Mac, and I removed the App, and all of the pertaining folders/files with Terminal. It could also be a virus, but I am almost positive it is something to do with MySQL. Any way that I can somehow stop System Preferences from freezing. I have already used multiple anti-virus programs to try to get rid of malicious files, and I have tried to repair system permissions numerous times.
I have two identities on my MacBook Air. In the main identity, System Preferences is frozen so I can't access it to make any changes. I want to migrate my files to the other identity and delete the original one, as everything works fine in the second identity.
ive had a look around an only found bits an pieces relating to this but nothing really specific.i have an imac 3.06ghz, 4gb memory. less than a year old its been making some noises recently (like a downloading sound for afew seconds every so often) which happens every 30 seconds or so. this happens even when theres no programs open and im not connected to the internet!!! ive only really noticed it doing this the last month or so to be honest.
the computer has also been re-formated about a month ago as it was passed onto me from a family member, an im wondering if its got anything to do with that?is this a normal thing for macs an maybe i just havent noticed it before, or does it sound like something is wrong??
I've begun to notice a ring, roughly three inches in diameter, in the middle of my Air, Rev C, Screen. It is a white ring, a couple of millimeters thick,that I can see best behind an all white screen, i.e. a blank page of a word processing document.
Anyone seen anything like this before. I can actually see part of it right on the white of the page I am typing in this thread.
so heres what happend. my macbook has been acting strange. freezing and sound not working at times. system preferemces quitting etc. and i just got it back from its thrid repair. THREE REPAIRS IN LESS THAN 3 MONTHS> so i was downloading a game for my psp when i went to go get a bagel in the kitchen. i left for no less than a minute and when i came back the screen was black. i thought it just dimmed itself but no. i moved the trackpad clicked on all buttons click the mouse button everything. i noticed the light wasnt throbbing so im sure it wasnt sleeping. the light was just pure white(the sleep light) so i waited like 3 minutes than shut it down. do u know whats happening. i know now i will be getting it replaced but until then im trying to keep it working well enough that i can watch a ********** vid on youtube.
I bought a MacBook Pro 13" in August 2011. A few days ago, I started to get a triple alarm sound (beep, plus battery indicator light flashes three times) and the system freezes (no keyboard or trackpad input, screen stays on). The triple beep continues until I shut it off through the power button.
