First, my MacPro did not accept my password. Earlier, our building had three power drops in a row, seconds apart. I don't know if this affected my computer accepting my password.Since then, my computer starts to boot up then suddenly shuts down. Is there some way I can boot up and get to admin controls?

2 or 3 months ago my charger broke, I havnt used my macbook pro since then, until recently when I got a new charger. Now my Mac wont start up.Or, it starts up then shuts itself down again.
View 3 Replies View RelatedAll of a sudden I was restarting my Air and now, it just has the spinning wheel for a few seconds and then goes blank and shuts down. I have tried everything the 'guide trouble shoots' but nothing has worked. Even was able to test the hard drive and it came back with no trouble. I tried to 'return to factory setting' but no luck and also tried resetting the Parameter RAM.

I recently upgraded to Yosemite. Had problems with connecting to the Exchange server so I did a restore from my time machine from the day before I did the upgrade. Now the machine starts to turn on, then shuts down. The iMac does not have a CD drive.
View 1 Replies View RelatedMy iMac will chime, then hang on the grey apple screen with the spinning gear. After a few minutes, it shuts off. Tried resetting Pram and all... Did not work. I troubleshooted using another website, and found it to be an I/O Error. The issue is I need to reinstall the OS, however, when I boot the install CD it hangs the minute I click the mouse or keyboard.

I went into my office, saw that there was a Safari update and decided to let it do its thing. When I came back 30 minutes later, my machine was off. I turned my machine back on, got the gray Apple screen with the spinning cog and the progress indicator for the update. A little over 10% through, the progress indicator reset. No biggie, I figured. Second time it got to the same point, it just shut down. Nada. When I restart, it does the same thing.

Purchased this notebook used, but very nicely cared for, excellent condition. I ran the Apple Hardware Test and everything passed including the logic board.
The battery has 500+cycles. The problem is laptop shuts down at 50% or less of battery. Clock is wrong at startup but is correct a few seconds later.
Runs forever and very nicely on ac power.
I am having trouble starting my 21" iMac running Snow Leopard after I had shared the HD with my MB-Pro. I had removed the "everyone - Read Only" rights on the HD (on the iMac) and opened sharing so my MB could attach to it. Grey Apple Logo and progress circle upon startup now.Can changing these rights cause the system to not boot? I can go into single user mode but I am not sure what to do then.

My best guess is the problem is not specifically hard-drive related since all the 'normal' fixes just won't work. The only way i've managed to keep the Macbook Pro on for longer than a minute is through target drive, where it seems to work just fine - i can access everything. To sum up everything:
1 - I tried resetting the PRAM
2 - I tried to go in to safe mode, it shut off before i could type the password
3 - I tried fsck -fy command from single user mode, sometimes i can get to actually typing it but mostly it shuts off before
4 - I tried to repair disk via target drive - success, no problems detected
5 - I reinstalled OS Mavericks.
The Macbook Pro previously had some problems with the power-button not working properly (a mac-cunning friend of mine had to open up the mac and start it by swiping to metal pins on a specific (battery/power?) part inside it.

I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware)
So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button.
I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.
on startup, macbook pro showed flashing gray folder with question mark, but no startup. After several retries, now shows circle with diagonal diameter, and still no startup. worked fine yesterday.

6 month old MBP 15", been running 100% fine, plugged it into a projector the other day and it auto changed the screen resolution. I unplugged the device, went into settings and changed my screen resolution back to it's factory size as well as command & the minus key to make sure I wasn't zoomed in on anything.
I then did a system update for the following; Airport utility, Safari, Ricoh Printer, Digital Camera Raw, java, Itunes.
Restarted the computer as the updates had finished, then when turning back on the loading screen with the grey background, apple symbol and rotating loading symbol was zoomed in as much as the resolution would allow. So i restarted a couple more times, still the same thing - every time i turn the computer on the loading screen is massivly zoomed in, once it's done loading and moves to the log in screen it is fine.
I've tried plugging into the projecter again and editing my settings, that did nothing. It's like because i updated while the settings where wonky it's saved it somehow?

My brother's iBook G4 (I think it's a 2003 model) has a problem with the screen. When the computer is turned on, the screen stays black, although the backlight is on (the apple glows). Sometimes, on start up, the screen works normally for a random amount of time before going fuzzy and then black again.
Any ideas on how to fix this? Is it likely to be a problem with the hardware in the actual computer, or just the screen? Or is it a software thing?
I'm considering buying a used MacBook Pro (early 2008) from a seller on eBay. The seller disclosed "Sometimes the machine shuts down after startup" but adds that he does not know why.
Does this sound like something anyone has encountered and if so, was it serious?
My Mac Pro display shuts down on me and goes into a kind of sleep mode but will not wake up, the monitor says there is no connection. This happens during playing video games or browsing the internet on both the mac and pc side. I thought it was the video card (gt 8800) so I bought a new card through apple (ati 4870), after installing the new card yesterday the problem came up again.

My iMac (21.5") turn off by itself and it doesn't turn on until I unplug the AC from the back and let it rest for at least half hour!!! If I try to turn it on I only get fan and drive noise but no screen at all... The longest time I let it rest, the more time that I can use it. I already reset PRAM. I'm runing 10.6.3 and the biggest software I use is ArchiCAD 13...
Does anybody have a similar issue with his/her iMac?
PS. Sorry, I don't speak/write good English but I did my best...
whenever i use my dvd the i mac shuts down, like i pulled the plug. No report, no evidence of somthing crashing. Either burning a DVD or copying the files to the desktop causes the same problem. I just re istalled mac osx the problem insists.
View 1 Replies View RelatedMy computer started to shut itself down without warning at around 10% battery power when my battery was bad. I bought a new battery, which works fine, but the problem persists. The computer does never tell me that battery is low or anything; it simply shuts down at 10% without warning and I can't seem to be able to do anything about it.

Starting today my Powermac has shut off suddenly a few times in ~15-20 minute intervals. When I have many applications open simultaneously the computer is especially prone to this.
I have never had this happen before in the 3+ years of using this Powermac, and the only differences I can see are that I've switched to a different ISP (I switched from earthlink DSL to Comcast cable), and I now have 4 computers wired in to my 4 port switch router. After turning on my computer I also noticed that my router requires a reset and the internet doesn't work until I do that.

View 6 Replies View RelatedI have a G4 Power Mac. It's the "digital audio" model that has been upgraded with a 1.2Ghz G4 processor. It works well except for one thing. It shuts down randomly and suddenly. Then after 5 or 10 minutes it turns itself back on, reboots and runs fine. (It is set to re-boot after a power failure.)I suspect what is happing is the power supply is turnning itself off due to some kind of a thermal, self protection switch. The fan seems to work but the PS gets warm.What's the cure? Replace the power supply? If so where to get a new(er) one?
View 1 Replies View RelatedI hadn't been using sleep mode on my iMac G5 for a while (but it always worked previously to me setting it to "never"), and now yesterday when I turned the sleep mode back on, it has decided it wants to shut down instead of sleep. But it's not a nice shutdown...it just powers itself off, as if it was unplugged. It always boots back up with no problems.

My MacBook suddenly shuts down in the middle of my work. Shut down as in a sudden shut down, as if the battery was removed. There is no shutdown process, the whole screen just goes black. I've realized that this happens more recently when watching youtube videos, playing flash games etc.
Example : Computer dies in 10 minutes when watching videos/playing games. Computer dies in a few hours or NEVER when just typing, surfing.
It doesn't seem to be a battery problem. I've removed the battery and had my Macbook run on the Charger before, and it still died on me...

I have a power pc and recently installed some new RAM. All worked fine for a few weeks then the computer randomly shut down. I would turn it back on and it would chime but shut down again before it was finished booting. Thinking this was the new RAM I took it out and rebooted. All was fine. To cut a long story short, I now get this problem with any configuration of old RAM and/or new RAM and to allow the computer to boot successfully I have to at least take out a RAM card and then put it back where it came from...
It seems though the new RAM did trigger something but this now happens no matter what RAM is in there. Also, taking RAM out seems to reset something that makes it start up OK. Any ideas what could could causing this..?
