So I recently purchased one of the discontinued unibody MBPs from my local Apple reseller, got the warranty reset to the proper date, etc etc. However, I have had this thing randomly, without warning, restart on me. There's no real rhyme nor reason to these restarts. It has happened twice now. Once while I was opening World of Warcraft and another just while the computer was sitting idle. The only warning sign is that my USB mouse goes all wonky and jumps around then BAM restart. Currently I'm running the Apple Hardware Test on it and typing this from my iMac across the room, it hasn't failed anything yet, but then again it's only been running for a few minutes. Does anyone else know of a possible fix? Is this something I'm going to have to ship off for repairs? I'm a little unhappy that one of my speakers sounds as though it is failing as well, so I should probably just buck up and send it off anyway while it's still under warranty. Ran the Apple Hardware Test and it came up with nothing. I performed the extended test so as to be certain, no failures.
New owner of iMac 24" 2.8 since last March. Just recently I have noticed that when I take off for a few days, I shutdown the iMac and when I return home a few days later and hit the power button the iMac is already on in sleep mode. The only change I have made recently was to add Time Machine on a Guardian Maximus 1TB raid drive, but I usually power off that drive when I leave. I've checked and searched here and in the Apple discussions with no luck. Does anyone have any idea what might be happening?
my late 2006 macbook running 10.4.11 has been acting very strange since yesterday. first, it freezes while i'm recording something off of isight and i have to restart. works fine for 30 minutes until it randomly restarts (probably due to heat) and takes me two reboots and some time to fix it (i have to put an ice pack to keep it cool). then later in the night, it randomly restarts again and takes two reboots to get it back. then in the past hour, the screen has frozen, it went into a kernel panic and it randomly restarted again while i was trying to post this the first time. and also, it's been running very hot despite having no applications running.
I have some issue with my 2012 Macbook Pro Retina. The screen intermittently decides to just not work. Sometimes on startup i hear the start up noise but the screen doesn't turn on. I am able to remote into the computer when the screen doesn't work. I can't seem to find any rhyme or reason as to when it works and when it doesn't. I've reset the PRAM and SMC sometimes that will bring the screen back sometimes not.

I have experienced in the last few days a sudden shut down on my MacBook Pro. I've searched the web and found something about RSS (Random Sudden Shutdown) but I still can't find a solution.
My iMac ( late 2012, 27", 3.4 GHz i7, 16 GB RAM, 3TB Fusion Drive, OS X 10.10.1 ) has taken to randomly restarting for no reason that I can find. It seems to be mostly when I am not actually doing anything, but, as I say, it's random. It did it five times in about half an hour the other day, then it didn't do it for a day or so, but it just did it again, which prompted me to ask. I have run Tech Tool Pro 7, and everything has passed. I have repaired permissions ( there were lots ). What next?
Has anyone had the following problem? My Macbook Pro is 2.5 years old and has recently been shutting down for no apparent reason while plugged and unplugged into the power adapter. I went to the Apple store a few weeks ago for an issue where the Macbook Pro would not turn back on at all. They had to replace the logic board. But after that, I now have the problem of the shutdowns. I went to the Apple store and got a new power adapter because mine was broken. I thought that would be the problem, but it isn't. I also recently reinstalled my operating system and the problem is still occurring. Does anyone have any advice? My laptop is a 2.2 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM. My battery is in 'poor' condition, but according to the Apple experts, the battery has nothing to do with this issue.
I've been having an issue with my Macbook Pro, it keeps turning off while on battery power while I am playing a game (Starcraft II) despite having sufficent charge remaining. It won't turn back on until I plug it back in. Usually when I turn it back on the time and date are reset and the password to my wifi has to be rentered. The most recent time this happened after I plugged it back in the battery still had 79% charge remaining. I've tried recalibrating the battery and resetting the SMC both which did not solve the problem. The system report states that the battery's condition is normal and I ran a hardware test which also came back normal.

I have an iMac late 2012. Since upgrading the OS to Yosemite, I have had random drops in my wifi. I have already tried 'forgetting the network' and Deleting the system config stuff. I still get this random drop. My computer is unreliable. Dropping during an online exam is bs because it screws everything up.
I have never experienced Wifi drops in my life and I am starting to get annoyed with this.
My keyboard and mouse is using bluetooth... Does that have something to do with it? Should I just install and use Windows instead?
My iMac 27 late 2010 does not shut down when shut down in the normal way. I have to shut down with the push button. I have tried disconnecting all the usb connected hardware still no use. Can any body help.I have OS Lion 10.7.3?
My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?
My macbook sometimes reboots while I am using it. I may be running 2-3 programs and it randomly restarts but no other problems as far as I can see occur. Does anyone know why it randomly restarts? It does not happen that often but every once in a while.
I have a problem on a G5 tower. OSX 10.4.11, dual 2.3gh with 2.5 gb RAM. Every few minutes finder restarts. Even if nothing else is running, the finder window will just close. Other programs seem to run fine.
I've just upgraded to 10.6.1 from leopard. Whilst on leopard I had no problems at all with my Macbook Pro (Early 2008, 2.5Ghz) and for the most part snow leopard seems to work pretty well. However I'm having some issues with sleep. To start with my computer wouldn't even shut down properly after installing snow leopard; it would shut down for 3-4 seconds and then restart of it's own accord.
I've tried a few solutions that I've seen in forums for people with similar problems (such as reset PRAM, SMC, repairing permissions and deleting certain PLIST files) and now my mac will properly shut down, but still not sleep correctly. Now my mac will only sleep if it is on battery power and I activate sleep by closing the lid, if I activate it in the menu or if the power cord is connected (by any method of activating sleep) then my mac will sleep then 3 seconds later turn back on. As far as I'm aware I've got no programs that are causing this and I have turned all network and bluetooth 'wake' demands off. I also have nothing connected to my mac.
I used to work on Windows normally without any problem but recently when I press the switch button on the mac so I can choose the Windows HD my computer restarts, it tries to load windows but ends restarting, I thought that maybe the partition died or something but I can see that everything is still in it's place ( From mac I click on Windows HD and I still see it's content)
For the last few months, my MP has had a strange quirk. When I select Shutdown, the computer restarts instead. Then, at the login screen, I select shutdown and it will then turn off. I've tried disconnecting all USB and Firewire connections (except keyboard and mouse) with the same results. It does seem to be time related. For example, if I start up the computer, get to the desktop and then shutdown, it turns off no problem. However, after its been running for a bit it will do the restart thing instead.
My imac has been restarting while I'm away from it, as if instead of going to sleep it just does the restart. Nothing much has changed in terms of usage, i.e. no new software, etc.
iMac G5 Flat-Panel, MacOS 10.5.8: Computer will just stop, then restarts itself after about 10 minutes. Happens when on Entourage and on Facebook from Firefox.Recently noticed this iMac also now only boots when in a different room, on different wall-outlets???
I have never had a Mac Pro before, but I have owed 2 Imac's and a power mac and 2 MacBooks. The issue I am having is when I put the machine to sleep when I wake it back up it is like it does a restart. It does not start me back up where I was before.
i've been having some serious problem with my mac mini. Im trying to install a copy of leopard in my new hard drive and every time i try to boot the dvd holding the "c" key, the computer restart.
I installed Windows Vista on Bootcamp and left it running overnight last night in Windows and it appears the computer had restarted. I turned on the monitor and saw the login prompt for Mac OS. Any ideas on why it might be restarting? I'm guessing the computer went to sleep while I was in bed and had some issue there.
Every time I try to install the latest version of leopard when the computer restarts it's self and it starts to "Configure installation", it freezes. I really don't think it should take OVER 12 hours to STILL be "Configuring". I called Apple, and the representative told me that I might need to install safari, but, it won't let me. Heh, I don't know what the problem is. I have an iMac G5 with 57.21 GB on my it. Does anyone know of any solution for this issue?
I have an early 2008 MacPro-10GB memory. Recently switched out two of the drives and decided to try a mirrored RAID setup with 2 3TB Seagate Barracuda drives as the boot set (using Lion 10.7.2). Ever since, I have had random episodes where the finder quits, everything closes and then the finder comes back up and is ready to go but all my programs have been shut down in the process.It can happen as often as four times an hour. I don't lose more than a couple of minutes of work but if I'm iChatting, I suddenly lose the connection or scanning stops or printing stops. Should I not have tried to set up the RAID?
