MacBook Pro :: Mid-2012 Turns Itself On And Off Repeatedly?
Sep 2, 2014
I went to boot up my MacBook Pro and during the startup it turned itself off. Before I could try to turn it on again, it was rebooting itself and then instantly turned off. This now happens repeatedly, with the boot up sometimes reaching the grey loading screen and sometimes not, but it continuously shuts down and reboots until I hold down the power button for an extended period of time.Â
2.- I tried to turned on pressing the turn on/off button and it did not do anything.
3.- I disconected the computer form the wall and wait for some minutes, and it did no do anything.
4.- After about 20 minutes i tried again and turned on by pessing the on and off button.
5.- The imac turned off again and disconected form the wall and conected to another electrical contact at the wall, adn it did not turned on. i wait for some minutes and turned on again, but after about five minutes it turned off again.
6.- I left the imac connected to the wall for a couple hours and i tried to turned onn by pessing the on/off button and it did not turned on.
7.- I left all night connected form the wall and tried to turn it on this morning and it did not turn on.
8.- This time, I only disconnected the imac cord form the back of the computer and left it for a couple of hours, then I concected and turned on
9.- All the times that the computer turned on it started like a restart and no announce or windows appear telling me about an error or something like that.
10.- One of the times I touched the computer at the back and felt it hot, not too hot, but I do not how normal is.
11.- I can feel some very, very little air at the back form the vent.
What do I hve to do? What kind of tests can I do to know if the computer's an is working ok?
i am a teacher in a school where we have been told that every student must shut down each MacBook or iMac when finished. It is not unusual for 6-8 classes a day to do this. I have said putting the MacBooks to sleep would be better for them. Some of the laptops are taking 5 minutes to restart. Can't find data from Apple to support my concerns.
I'm using Mac OS X 10.6.8. I was just using skype an hour ago but now it keeps quitting unexpectedly. My internet hung so I forced shut it down, restarted in Safe Mode, exited it and started it on the normal mode. I opened skype in safe mode and it was fine! but after that, when i exited safe mode, the error message that skype is quitting unexpectedly keeps showing up! ive tried everything - deleted the files in the skype folder, reinstalled skype but nothing works! I have an anti-virus installed on my mac so I've scanned skype and nothing seems to be infected really desperate now because I use Skype on a daily basis.Â
I have a late 2007 black macbook that I loved. I didn't use it much for a year but since my other computer is dying, im using the macbook alot more now. I am starting to hate it. The main reason is because I can't listen to any music peacefully. I would go to youtube or a artist's myspace page to check out some of their songs. When I would play the song, it would repeatedly freeze and I would have to pause it for a couple of seconds. Then when I pressed play again it rewinded a couple of seconds. It would work for another ten seconds then freeze again, then play and freeze repeatedly. It is so aggravating. My second complaint is that it takes forever to load a webpage. The beachball would replace the mouse pointer several times. I can't ever go to a webpage without the beachball showing up. I do live on a college campus but it hadn't done that the first couple of weeks when I started using it here. I feel like there is a real problem and I can't peacefully listen or sample any music online or in iTunes. Another thing, I once mistyped [URL] by typing and it brought me to a dark grey screen saying warning! malicious software on this site and has the buttons saying "go back" or "continue". I clicked the back arrow button and pop up brought up saying they needed to resend info again so I cancelled and then x'ed out of safari just to be safe. I hope that malware didn't hit me at all. Let me know about my situations.
Mac is running latest OSX Mavericks software.... But lately, my Mac is crashing repeatedly when I attempt to use iTunes or iBooks, both also the latest releases. Syncing with either iTunes or iBooks is nearly impossible. No disk repair or verification errors. I am thinking that there is some rogue software glitch that has me. I am thinking that I need to do a factory reset followed by a time machine data recovery.Â
I just purchased a 15" MacBookPro (July 2010). I am not used to laptop keyboards so I was able to purchase a bluetooth Apple Keyboard with the Numeric keys. This bluetooth external keyboard was made by Apple and a local company had these brand new for $60. I was told they were the model that came with iMacs. Apple support told me that they should work fine but did not offer an effective solution. So at any rate about 70% of the time this Bluetooth keyboard works great.
But sometimes when you go to type something it starts repeating whatever key you hit so it you were to type and "a" an example the MacBookPro displays "aaaaaaaaaaaaaaa". Sometime just a few of the same character and sometimes it does not stop. I correct this by turning the power switch off on the Apple Bluetooth keyboard and then turn it back on and all is fine, for a while. Sometimes for a week or so then it will do it a lot for a while or just intermittently. The keyboard built into MacBookPro does not do this. I think it may be the Apple Bluetooth keyboard not the MacBookPro or its OS.
I am having an issue installing Snow Leopard on my computer. Every time I start the installation process, the process makes it to the first restart, and then crashes. I am running Mac OS X 10.5.8 and using a early 2008 Macbook. I have tried verifying the disk, but Disk Utility says the disk is fine with no issues. The hard drive was recently replaced so I doubt that their is a problem there...does anyone have any advice on how I should install Snow Leopard?
I'm facing an issue with safari. Every time I try to start the app safari - alert window pops up, and I cannot really close it because when I do, it shows again and again.
I had it repaired at the mac store and iphoto and imovie are missing, probably along with some other applications. I've tried looking for the install cd for it but I can't find it, now I'm starting to wonder if it even had one. If it doesn't, can I go back to the apple store and have them re-install my programs?
So I just bought my first Mac and I bought it as a open box. When i turned it on the Word was in spanish but everything else in English, and whoever had this laptop before me still has it registered to them (I'm guessing). I need to know how to reset it. I want it to be like i bought it brand new and not have anything that the person before me had on it.
I bought my Mac a little over a month ago and I'm really not impressed with it. I keep seeing the little rainbow wheel all the time. When I try to load a YouTube video the whole machine just stops working and becomes unresponsive for about 4-5 seconds. Also, when flicking between tabs on Safari it intimitantly becomes unresponsive. I don't do any heavy power consuming things on my mac. It's basically just for college and recently all I've been doing is using Safari, Spotify and Bittorent. I don't know what I should do. Whether to take it back to Apple or just deal with it. My old Acer laptop was fine dealing with this sort of stuff so I'm really unsure. I feel quite let down although I am a total apple fanboy. Â
I'm using VNC onto windows PC that has an application requiring me to use the PRTSC to start a recorder , but I can't find a combination of keys for PRTSC. I'm using a MacBookPro 2012 and REALVNC onto a windows 2008 server using a recording package. To start the recorder I need to hit PRTSC - How do this on my Mac so it hits a PRTSC on the remote PC? ?

I have a 13" Macbook Pro (mid-2010). I know that the RAM can be upgraded by just adding RAM to it. How about other hardwares like processor, harddrive, or battery? Can I upgrade it through Apple?
I recently just got a new MacBook Pro and I had my Sims 3 game from when it first came out.However, the game isn't being recognized by the computer. The case shows that the game is compatible with Windows and Mac. I heard if you install to Windows you can't install to Mac right?
I am between two laptops, the MBP 15 with retina display and i7 2.7ghz(third generation) and a dell precission m4600 with 2.7(second generation).Same other specs. 8gb ram, ssd, the difference are the gpu, geforce 650M, and the precission has a quadro2000.I will use windows almost the hole time, cause of CAD, and other win programs. But I will be only using 2d cad drawings mainly, so I believe I dont need a quadro. In addition, I want to be able to play some games, like wow or diablo3.So I will need bootcamp. The performance of windows on bootcamp, will be the same as a windows pc native? I read some issues with the wifi, is it true are there other issues? I believe i will have two partition of 512/2 gb for each OS
I want to buy a MacBook Pro (new 2012 model) and am thinking that buying the 13" 750GB 5400-rpm HHD model and then upgrading it to SSD myself will be a far cheaper way to go? Â
I recently purchased a mid-2012 MacBook Pro (15-inch, 2.3 GHz, non-retina) and I have been receiving Kernel Panic error messages. The screen goes black with white text in multiple languages warning me to shut down my computer and the computer freezes. I have called Apple customer service multiple times. We tried multiple things, including wipe the hard drive and reinstall OS X Lion, but I still get Kernel Panics. One thing I did notice in the "send to Apple" report is that it mentions Google Chrome. It seems whenever I do get a Kernel Panic I am using Chrome. Here are the applications I have installed (besides the default Apple ones):Coda 2Final Cut Pro XTwitterGoogle Chrome Right now, as suggested by the second Apple associate, I uninstalled Google Chrome, to see if that was the cause. She says that it could be related to that or from a software update (which I doubt considering I have yet to install any updates since I reinstalled Lion).Â
I purchased the Toshiba Dynadock U3 - which ran well with Win 7- hoping there would be drivers for the Mac OS. Anyone have any ideas how I can accomplish this configuration? If not, then what is the next best configuration where I do not have to keep connecting and disconnecting wires fron my MBA. Just want to connect one wire (e.g. - USB cable) that that's it. Is this wishful thinking?Â
Info: MacBook Air (11-inch, Mid 2012), Mac OS X (10.7.4)
Is the port layout on the new Macbook Pro (June 2012) the same as the late 2011 version? i.e. will the new Macbook Pro be compatible with a byte-dock docking station?
I have been using the same exact setup with the 2011 MBA but the new one won't work with my projector. I have a Acer X1161P 3D-DLP Projector and the proper cables since this has previously been working. I saw that in the first update there was something about external monitors.Â
Info: MacBook Air (13-inch, Mid 2012), Mac OS X (10.7.4)
My Macbook Air 2012 is showing CPU temps of over 100 degrees celcius when encoding video/playing games. This seems like it's WAY too hot.. is it normal?
Upgraded the 750GB Toshiba HD to a 512GB Crucial SSD and wow what a performance difference. I also have a 15" Retina to compare it against and the 13 read/write access if faster than the quad core retina. Sure the quad will be better with alot of simultaneous programs running but one off or two programs the 13 with the HD update outperformed.Â
On the 13" my startup time was 42-45 seconds after the apple logo appeared. Now with the SSD, 8 seconds. The program launching and performance improved 50%+. I would recommend updating to SSD if you are able.Â
