Macbook pro intel core duo. My macbook is turned off, when I press the power button the light goes on and the computer starts making sounds of turning on for about half a second and than shuts off. I tried removing the battery and putting it again, I tried to hold the power button (the light flickers at one point and eventually shuts off as well after 2 seconds), and tried turning it on with the adapter plugged in and unplugged.
My computer won't turn on. Earlier today while playin music it just paused itself. I minute later it resumed. Then tonight it just shut off instead of sleeping and now it won't start. All I can get if I'm lucky is the start up chime and a super quick flash of a white screen.
So jar launcher wasn't working for me so I decided to restart my computer but when I did there was a loading bar under the apple logo and it goes half way then freezes I am running os x yosemite 10.10 I found like a download of this online and no it wasn't torrent. So I turned it off again and tried it again and something happened what do I do right now its turned off.
Info: MacBook Pro, OS X Mavericks (10.9.3), 10.10 yosemite new mac version
My wife did an improper shut down by holding the power key while something was working on it. She is running mavericks on the system. Now it will start to boot and shut down when progress bar gets half way. Disk utility says it can not fix problems, and when I try to reinstall mavericks from disk utility, it either says hd is locked, or it won't show me hd.
I have a late 2010 MacBook Air.Unfortunately, I'm in a country without an Apple store or any kind of official Apple support (no phone number to call).
2 days ago, I plugged in a little USB modem device (wireless is rare here) and my laptop shut down suddenly. It refused to restart at all until I did an SMC reset and then it was working fine (including with the USB modem plugged in).
However, the next day, the same shut-down occurred (when I plugged in the modem again) and now SMC reset is not doing anything. I've held down the start button for a very long time and there aren't any signs of life. The light on the charger shows that it is charging when I plug it in.
Recently my macbook pro battery stopped working, i took it to the apple service and battery has to be replaced which they will do so soon. They told me i can still use it on the power cord. However when i started it up the screen has a spinning wheel and a loading bar underneath the apple logo, which it never had before, and when the bar is 1/3 done the computer just shuts down every single time at the exact same place.
When the computer is turned on the grey startup screen is full size then goes to half size for normal operation. I have already reinstalled the OS and zapped the pram. When I open the display window of the system preferences it shows the main display as 640x480 with no other options and a second display window with 1920x1080 and no options even though there is no other display hooked up. It seems like the main display is stuck in 640x480 which is why it is so small. Running OS 10.2
Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.
I was trying to install windows on my pro, and i had bootcamp chop the hard disk in half, but then my disk drive didnt read the cd so i had to download and install some file. and after i restarted i could no longer access the windows side, it just disappeared.....plus i cannot reset my hard disk, cant erase it, and i cant reinstall OS X because there is no memory left..
I have a MacBook Pro with the 9600gt in it. Since updating to 10.6.4 this morning 2 times while playing java games i've had the bottom half of my screen go black and most of the top half flicker. I've had to hold in the power button and reset both times. The second time I closed the screen and reopened it, the screen was black but no mouse and nothing moved.
Any advice? Would this be something to do with my graphics card or possibly some error in 10.6.4?Edit:: This is software related to 10.6.4 update and only happens when I open up a java game in a browser.
I've got a strange issue with my PowerMac dual 1.8GhZ and I can't figure out where it's coming from.Last Saturday I experienced a Kernell Panic while using Safari and the Dictionary (MacOS 10.5.1).Since then, whenever I try to start my computer, it shuts itself down while the grey screen with the Apple logo is on screen. However, this isn't always the case:I can use my computer 'normally' if I press the option key at start-up and manually choose my startup disk.
I can boot from a Panther or Tiger installation disk, but not Leopard.If I try the hardware test the computer shuts itself down in the middle of the test.TechTool works and didn't find any issues with my computer. Nor did Disk Utility.I tried to erase both my internal hard-drives and do a clean install of Tiger, but the problem is still there (I have to press option at startup).I tried to reset the PRAM and Cuda/PMA. Doesn't resolve the issue.When I tick 'Restart automatically after power failure' in Energy Saver my Mac will indeed restart, meaning it thinks there was a power failure.Any idea what it might be? And why it only happens in certain situations?Do you think it's a hardware or a software issue?
Information: PowerMac G5 dual 1.8GhZ Mac OS X (10.5.1)
My comp. has worked perfectly, Then I installed some updates, Itunes i think? And the comp. Shut down, and when it restarts it works for a min or two, then freezes, and i get the beach ball, that just spins around and around forever.
if I don't try to open anything, or do anything when i restart it, it will just shut down, and restart, then when it comes to the Grey screen with the apple and the little circle below it, the circle looks all pixilated, and just freezes
that is the version its on (Taken two days ago, and sent to a buddy for other reasons completely)
This has been a great computer - bought new in 2004. Recently started to click "off" as it was just powering up. I thought there was a bug - so did a clean and install for OS X - but still does it. The only way to start computer is to hold the Options & Alt key and P and R key at start up until I hear 6 dinging noises of start up (why six is the magic number I don't know. But it is the only combo that works!). Once it is up and running no problems.
My Mac attempts to start up and automatically shuts down on it's own. It continues to start and stop for several minutes and finally boots up. Once it's up it works OK. I've had it in to the Mac store and they tell me it's probably the power supply, but after leaving it on all weekend it seemed to work OK so they didn't do anything. After I brought it home it is still acting in the same way. It's only on trying to start up that it cycles through the start - stop action. Once I turn it off it's the same problem on trying to start again. Does this sound like a power supply problem?
when i start my imac it shows the apple logo, then the circle starts spinning and after a couple minutes it just shuts off. BTW i have windows on it as well so when i hold option it lets me open windows but not os
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
At the beginning of last year I bought a 3.2GHz 27" iMac. About a month ago I noticed that, within about 5 minutes of starting my computer back up from sleep the left half of the screen would flick and become darker than the lower half (about 4 clicks of the light button lower). Sometimes the screen will flick to become even darker than this (but usually it returns to the 4 clicks darker after a short while), and sometimes it returns to normal only to go darker again.
I started up iTunes, checked my email, and looked up to see the top half of my display drop about 15 shades darker than the bottom half! I called Apple Care who told me they had never heard of something like this before and advised me to call the nearest Apple Store. I did, and like Apple Care, they had never heard of this happening.
I have a white macbook that has been starting to act a little slow. I put avast on it and found some old files that were windows files received in emails that had never been deleted (i.e. so these weren't issues and so viruses were not the problem).
I did a repair disk permissions and it gave the usual long list of java changes. I did a verify disk, and it found errors. So I put the CD that came with the macbook into the drive in order to start from it and run disk utility.
The macbook will not boot from the cd. The drive is fine and the computer boots up fine using the HDD. I did try running the hardware test but it said the version is not compatible (maybe these aren't the disks that came with the macbook??) So I booted up normally and tried even to run disk utility from the CD and it said it was the wrong version as well.
I researched the internet and saw target disk mode but this old white macbook doesn't have a firewire port. So I just hooked up a carbon copy clone of my desktop from a USB harddrive and was able to boot from that and run disk utility to fix the errors. So the disk errors are fixed and disk verify shows no errors.
However, my only outstanding issue is that I cannot boot from the CD drive. If I'm on the road and don't have the usb drive and have trouble with regular boot I will not be able to boot until I get home. I have upgraded the OS since I purchased the macbook but only to 10.6. Do I need a 10.6 startup CD as opposed to the one that originally came with the mac?
I have an older style MBP, 2.2, running 10.4.3, and the other day after using it about an hour I put it to sleep. After another hour or so I opened it to use it again. Usually just opening it will wake it from sleep. It didnt so I tried pressing any buttons, no luck. Held the power button til it turned off. Tried to boot up but the screen stayed black and the sleep light went on, but did not pulsate. Tried that a few times with the same result. I also tried hooking up an external monitor, just got "no signal".
