MacBook :: Reboots Again After Its Done Booting Up?
May 19, 2010
I have an old black MB 2.16 ghz C2D. At times, it locks up and randomly reboots. Sometimes, it gets crazy and reboots again after its done booting up. Sometimes, I get this gray screen that says I have to hold the power button as well. I don't really notice the laptop getting warm at all or the fans turning on that much. I just reinstalled the entire OS and Snow Leopard. I just got a new MBP, so I haven't really been using that one as much (or at all). So, it's hard to say if that fixed it. My applecare runs out on 5/29/2010. And if it's a hardware problem, I'd like to get it fixed prior to my warranty expiring.

I've been digging around for a couple weeks now for information on what may be happening to my MBP. I've tried numerous solutions, but don't seem to be able to get the computer to STAY ON. Here's my story:
A couple weeks ago, my room mate was using the computer. She closed it to put it to sleep, and left it on my bed. When I went to turn it on, the screen was completely black and the indicator light on the open button was a steady grey. The computer was so hot it was painful to the touch. I unplugged it, hard powered it off, and let it sit, thinking it was an overheating issue.
Since then, the damn thing won't stay on. Initially, it would intermittently just shut off. When that happened, sometimes I could boot it back up, and other times it would sound like something was whirring in the background, but the screen stayed black and the indicator light stayed solid grey. I installed SMCFan and istat to monitor/control the temp and fans.
I noticed somewhere along the way that there seemed to be some connection between episodes of shutting down and the power cord (as in, if it was jostled, the computer shut off)(I should note that my battery is at about 15% health with a full charge). Then, that power cord died (no green/amber indicator light and no connection detected). So I bought a new cable, and set about trying to fix the problem again.
Next phase, it seemed that if I moved the computer, it shut down. So I did some of the recommended fixes. I deleted the power management plist, I changed the settings to never put the computer or the display to sleep, and I turned off the quick-motion sensor that stops the hard drive. I also reset the SMC settings.
This seemed to improve the situation a little bit, insofar as now instead of getting a shut down, I am now getting complete reboots that only *sometimes* lead to the blank screen and steady grey indicator light. This does happen more frequently if I move the computer, but it can also happen if I simply leave it to run. In fact, if I send the computer into sleep-mode, and close the lid, I'm practically guaranteed a reboot.
So, then I reset the PRAM and did the hard-reboot (ctrl+opt+power) and reset the PRAM again. I am currently running Rember to test the RAM, but I'm not sure what to look out for when it finishes, or what I should do about it.

First couple of times this has taken place I thought I was making a mistake or possible a power setting somewhere but finally yesterday I realised after checking all settings that my MacBook is actually rebooting and closing all apps for some reason.
Typically occurs when left alone for a hour - not every time - but at least 5 times so far this month. Has anyone else experienced this or do I just have a defect problem with the hardware? What can I do to troubleshoot this? Are there any system logs in this OS that would give me some clues if this is applicaton or hardware related?

My new Macbook Air (bought one mounth ago) reboots automaticaly. It happens randomly, usually when I'm using Safari or Skype. It shuts down without any warning and log-out process, and it's keyboard keeps unresponsive about 1-2 minutes and then boots up automatically. I'm not using any "Disk cleaning app". I have reinstalled OS but unexpected reboots keeps happening.

Last week I bought a new model 15" MBP which spontaneous reboots every hour or so. Yesterday I returned it and received a new one (including new power supply etc). This one however does the same. Yesterday evening I started a Time Machine restore which was stopped in the middle because of a spontaneous reboot.
I resetted everything (SMC, PRAM, etc.) and tried again. Still reboots after apprx an hour. It doesn't run too hot (67C, 2100RPM). What can be wrong?

I just bought my new 2012 macbook pro a couple weeks ago, and so far it has crashed and rebooted by itself four times. Three of those four times, I had only been running a couple programs, such as Chrome and Mail, while all others were closed. the entire computer will freeze for about 6-7 seconds (no response to mouse movement/keyboard) and then shut down and reboot. Â
Is this a bug with OS X Lion? or the new macbook Pro? or my macbook pro specifically indicating there's some sort of defect?

Whenever my Macbook powers down to 0 battery life and reboots from a new charge, I loose all my software settings, including browser cache, adobe settings etc. It's really annoying. I have a brand new MacBook Pro 15" 2.2Ghz i7.I'm running OSX 10.6.8 on it (I reverted because I didn't like Lion).

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.

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.

I recently updated to snow and since then have had problems turning off mac. I've reset pram, tried unplugging externals, tried logging out, then shutting down, but every time I hit apple-shutdown it goes black, and reboots. I can put it the screen to sleep with hot corners, but never turns off unless I manually hold down power.

Is there an event log or something? I leave it on all the time, good airflow around it and it's on a ups. It didn't crash for the first year but now it's almost daily. I use this one for the house itunes server so it's extra frustrating. Any ideas on what to look for? I've made no mods at all, even the RAM was from apple (when I bought it).

Do you guys recall when one of the advantages of Mac OS X over Windows was that it required fewer reboots after software updates and installs?
I recall it being one of the selling points in maybe a few of their commercials and advertisements, way back when, along with "quicker boot times".
It seems that -- nowadays -- I'm required to reboot OS X almost every time their is a software update for the OS or value-added software, while my Windows box seems like it goes months between required reboots after Microsoft software/OS updates.

Mac Mini was running really slow. So we reformatted the hard drive and restored the computer using our restore disk and our Time Machine backup. After restoring our system, when it reboots, it reboots to a blue screen. It sits there and sits there.

I am having an issue with using bootcamp to install Windows onto a 25GB on my 2010 2.4GHZ MBP.
At the stage of installation when windows setup reboots the laptop, installation does not continue, instead a black screen appears for a while then the message press any key to boot from CD/DVD. Doing this then starts the setup again from the start.
I have partially remedied this problem by sitting at the laptop during installation and at the point of restart holding down the option key and selecting to boot the windows drive which then recommences installation.
However after a minute or so of 'finalising installation' (or something along those lines) the system completely freezes, the mouse does not move etc and it will sit there happily for 30 mins without doing anything until I turn it off.
This has been tried with 2 copies of Windows; a genuine copy of Windows Vista 32 bit and a perhaps not so legitimate (OEM edition) of Windows 7.
Both have the same problem of restarting to reload the disc from the start, although I have only tried my partial fix with the Windows 7 installation (will try on the Vista disc tomorrow).
The apple support on the issue is very vague and their guide essentially skips the whole installation of windows - goes from booting the setup disc to after installation install your macbook drivers >.>
Any suggestion on what the issue may be?
All help appreciated as I really want Windows on my system in the next few days before I go to university so I can use Microsoft Office on it (do not feel like buying a new version for mac).
Are there any other potential solutions for me to use my Windows Office on my mac? (I'm a complete newbie to mac, have only had the machine 3 weeks or so, I've heard about virtual drives and so on but don't know fully how they work and don't see them as the better option unless absolutely necessary)

I do not have AppleCare on this machine. I've got a 27" iMac that will randomly shut down, be it in the middle of playing music on iTunes, while I'm typing a document or while the machine is simply in screensaver mode doing nothing. Usually the machine tries to instantly reboot itself. All too often, it cannot be rebooted and I have to let sit for quite sometime before it will even power back on. Lately the problem has gotten worse, almost never reboots by itself.
Finally, in the last few days, it just won't turn back on. Nothing. My biggest concern is that I have an unreleased music album from an instantly recognizable major client on the iMac's hard drive, not due out for many more months and still unannounced. I can't simply take the computer into an Apple store for troubleshooting as those files are worth and could cost me exponentially more than even a new iMac outright ever would.

I had this issue before and posted about it here, but no one seemed to really have an answer for me.
I'm asking again because maybe something new has come up?
I've been having an issue running games in Windows for some time now. They run fine, but then sometimes it will freeze up, then my whole computer reboots. I don't really know why it does this, and it happens randomly. I could be playing for hours or minutes before it does this.
Does anyone know why this happens and how to fix it?

My machine: first generation intel iMac, 2 ghz processor, upgraded to 2 gigs of ram, circal summer of 2006. Using OS 10.5.6 and Windows XP pro, corporate edition.
The problem: Every time I try to log into windows, the machine reboots as soon as it reaches the desktop
When I first installed bootcamp/windows, I had some trouble but once I figured out the mistakes I was making during installation, it ran normally. That was a few months back. The other day, I go to use windows for the first time in a month or two ( I really only use it to play Fallout 3, and I've been too busy for it until now ). I try to log in, but my keyboard and mouse don't work. After multiple restarts it's clear that there's a problem, so I go online, research it, and find only two solutions: a repair install of windows, or a complete format and reinstall. After repeated attempts at the first, I ditched my scratched up windows disk and got a new one, and started with a fresh reinstall after I managed to back up my files by accessing the partition through OSX.
The reinstall went normally, and everything was fine until I went to restart the machine after installing the bootcamp drivers from my OSX dvd in Windows. Reboot, log in, and then about one full second after reaching the desktop, the machine reboots. It will automatically start in windows, unless I go back into OSX via holding option and selecting it, then reset my start up disk to OSX. Every time I try to get into XP, the same thing happens. I google it but find nothing, save the one point that disabling the automatic restart in case of error during startup function does not help. After multiple reinstalls from my own new copy of XP and a friend's different version, I get no changes.
Today, I downloaded an updated driver set from apple.com: I install XP again, install the drivers from my OSX dvd again, and then use the downloaded driver updater to update the drivers. Then I reboot, this time using F8 to disable the auto restart, just for kicks: surprisingly, the computer starts up and logs in normally, and I use windows for a few minutes to make sure it's not going to restart. I reboot into OSX, copy over the files I backed up, then attempt to go back into XP. And of course, the problem's back again. I wipe out the hard drive, and start over, thinking that maybe if I permanently disable the auto restart, it'll solve the problem. It doesn't: this time, it's back to how it was before, and I have yet to get another successful session out of it besides the one mentioned just above.

For the past month or so, I've started to have some really weird problems with my Mac Pro. Applications will suddenly stall out or freeze up (endless rainbow wheel), and Force Quit won't work to quit them. It happens most often with iTunes and Finder, but it's also happened with Firefox once or twice. The whole system doesn't freeze or stall - I can generally still use another application (i.e. if iTunes stalls and won't quit, I can still continue to use Firefox, etc.), but generally if I leave it this way too long another application with eventually freeze, forcing me to shut down by holding down the power button (Shut Down won't work in these cases).
Occasionally when this happens, I have left my computer alone, and sometimes it unfreezes or unstalls by itself, but this is usually hours later, and sometimes it doesn't do this even after hours of waiting. I ran a hardware test thinking that faulty RAM might be the issue, but the hardware test said everything was OK. I don't know if I should believe that or not. I've tried repairing permissions and verifying all disks, internal and external, and everything checked out OK. What is going on here? Why do things keep freezing/stalling and forcing reboots?
Here is what I've got:
2x2.8GHz Quad-Core Intel Xeon
2GB 800MHz DDR2 FB-DIMM
Running Mac OS X 10.5.8
I have really normal stuff installed - MS Office, Photoshop, Ableton, etc. No really weird third-party applications other than some really simple stuff. I'm not the type to overwhelm my computer with a bunch of crap.

So, back in the day, when my MacBook Pro's battery would die while asleep or on and you plug it back in, the laptop would essentially revive itself from your last used state. Its like waking from sleep, but takes longer because the computer has backup the memory state to the hard drive.
Its seems my MacBook Pro no longer does this. When the battery dies and I turn it on, it reboots. I am not sure if it is related, but I have modified my MacBook Pro by removing the optical drive and replacing it with an 80GB Intel SSD to compliment the 500GB 7200rpm Seagate. The SSD is the boot disk and is in the DVD Drive's old spot.

I have been running a Mac Mini OS X Server for last 3 months without a single error. I have 2 of them. Yesterday, I upgraded to 10.7.4 (from 10.7.3) and today, one of my servers has crashed twice. Both times, it has rebooted (no Monitor attached to Mac Mini). It is out of service for 10 mins or so. This concerns me, as it never rebooted before 10.7.4. Also, other Mac Mini OS X Server doesn't have an issue. I usually wait a few weeks before installing software updates on servers - but I decided to yesterday (Sunday), because I had some time, stupid me.

Sorry for misspelling on title line. It should be --lose not loose. So it used to work just fine. I obviously did something wrong. Retracing my steps as follows:
1. Cloned my original single drive with iTunes and iPhoto data already on it. Clone worked same as original-just fine.
2. Then took new SSD-formatted and partitioned and did clean/hybrid minimal OSX install plus transferred applications, library and home onto new boot drive-about 28GB.
3. Then took larger SSD formatted and made 2 partitions-one for iTunes 160GB and 2nd for iPhoto 80GB.
4. Used drives in external enclosures to test. Could not get any iPhoto picture data to show up after unmounting and iTunes has the content, but after unmounting iTunes (along with iPhoto since on same SSD) all database (album artwork, etc) disappears when I reboot and go back to either Application-iTunes or iPhoto. What did I do wrong?
