MacBook :: Starting Up But Not Booting?
Apr 17, 2010
so I have read most of the start up problems, and mine is different. Whenever I shut down and try to start my computer again, I am not able to get my computer to turn back on. I hit the power button, and hear the computer humming, but not the typical hum-hum that usually occurs. My screen remains black with no activity. After 5 to 10 attempts at this, the computer starts up fine, and I have no problems with it running. I do not have this problem when I use the restart function, say after I download a software update. This problem is driving me nuts as I am afraid I can not shut off my computer!

Yesterday my MBP suddenly froze while starting Google Sketch. Not just the program, but the entire computer. After a few seconds the screen started flashing like crazy. I waited a minute or so before I forced it to shut down.
After doing so I turned it back on and now it will not start up. I can turn it on, but then I will only see the turning wheel thing you always see. After a few minutes of turning wheel the wheel will freeze.
Talked to my local macstore and they told me to try and reinstall my entire system before sending it to a repair guy. And here is my problem.
It will not boot from a Cd or en usb with Lion on it. Not when holding "C", shift or any of the other keys down.
This morning I managed to boot from the system CD and erase my harddrive and start installation but, then it froze for an hour andIi had to shut it down again. Now I am back to not being able to boot from my system CD. Â Â
Is it a hardware error or what. My Mac is pretty old. It is the one just before the current MBP design came out. But have another computer, but I use this one a lot, so it is really frustrating that this should happen just before a possible new Mbp design.. Â

On starting up, my macbook pro shuts down after 25 seconds of booting up. The time bar comes on for a while before it simply goes blank and switches off without any notification. Battery appears charged. Could it be a virus?

I've had Last fm for a while, and whenever I plug in my iPhone or iPad, it will randomly start on its own, even after I force quit the app, it keeps doing it, and it drives me insane, it'll start up in the most inconvenient times, and I have to quit it at least three times before it finally stops starting itself. Is there a way to fix this, or do I just need to uninstall it and be done with last fm ?

"You need to restart your computer. Hold down the power button for several seconds or press the Restart button."
I get this message everytime I turn on my MacBook Air and cannot get past it.
When i turn the power off, it hang for quite a long time and this screen appears,
Macbook Air OS x 10.5.
Before this happened, i went on skype and firefox. But then it hanged, so i had to hold the power button to shut it down. I meant to restart it back but then i couldnt. This problem appears.
Just before it happened, i dont have any start up application. But before, they were adium, skype and transmission. And my 'HUAWEI mobile connect broadband internet' connect automatically. and i dont use time machine.

When i try to start my macbook pro 13" (early 2011) I get a black screen and it beeps three times. Based on internet research it appears to be a RAM problem. The closest store is 2 hours away and I don't want to send it away.Â

It seems like my MacBook Pro starts up pretty slow, about 20 to 30 seconds. I don't think this was the case before, I have the HD almost full but it has been like this for a while and just a few weeks back started to do this slow start behavior.

I recently upgraded the RAM and Hard Drive in my Macbook Pro 2012. I know that the first time it boots up it is suppose to boot up slower, but what about the times after. I upgraded the RAM to Corsair 8gb 1333 MHz DDR3 and the Hard Drive to the Seagate Momentus XT 500gb.

I have a Mid 2007 MacBook (Core 2 Duo, 2.20 GHz, 2GB, OS X 10.6.8 Snow Leopard) and I am having a problem with iTunes. I have a fresh install and was going to sell the computer to a client when I realized that iTunes had a serious problem. Whenever I go to launch iTunes, I click on the dock icon. It bounces multiple times on the first attempt, but the program never launches by showing "iTunes" in the top menu. The little light never comes on beneath the icon either. Also note that on each attempt afterwards the icon only bounces once and then stops.

I upgraded my MacBook's ram tonight and now when I turn it on the Apple logo an spinning thing come up then after a bit the screen dims and it says, "you need to restart your computer. Hold down the power button untill it turns off, then press the power button again." I had two 1gb sticks and I put in a 2gb so I'll have three. I put the new one in the top slot but accidentally poped up the bottom one too. I've tryed about four times and put the original one in and get the same results. Could it be that I didn't push it in enough. If I can't get it to work tonight can I take it to the Apple store for them to see, and will I still be covered, I know they don't cover the new ram.

I bought my 13" Macbook Sept 2007 and I've cleared it off and reinstalled everything once since I bought it just to keep it clean.
I haven't had any problems until yesterday (June 28, '09), I tried to start it and it won't go past the gray screen with the logo and spinning disc.
I've tried these suggestions:

None of these have worked. Tried the PRAM, taking out the batter and adapter and holding down the power key etc.

I have a G5 powerpc that is flashing a question mark. Whenever this has happened in my life with previous Macs i have pulled out my trusty install disc and fixed the problem, however i have lost the install disc.
I do have an intel MacBook Pro. Is there anyway i can wipe and install OSX on my PowerPC via my MacBook Pro without buying an OSX install disc?
Also, i had read that i could boot in safe mode by holding down shift but this has no effect. Does anyone know why?

I'm so worried. I turned off my MBP as usual yesterday and when I tried to turned it on today I get a white screen with the Apple Sign and a loading bar which never ends up loading. Nothing like this has ever happened and I haven't made any hardware or software modifications on my MBP. I thought the days of my computer crashing were behind once I switched to Apple. Ugh I don't/can't afford to lose all my files. I also tried booting from the OS X disk and trying to repair the disk but it tells me it can't be done.

I have a mid-2010 15 inch Macbook Pro. After putting it off for some time, I went to install the 10.9.3 update. However, after installing the update, the computer won't start! A progress bar appears under the Mac Logo during start-up, but it only gets about 1/5th of the way through, when the bar disappears and then the mac shuts down. I've attempted this at least 5 times and it always does the same thing. I held option during start-up to boot into the Recovery disk, and tried to repair the partition (I also have a bootcamp partition), but it said it was unable to repair.

I have a Macbook Pro 13in. from I believe 2008. Last night I was watching Netflix, with no other applications open, and within 2 minutes my computer shut down. I thought it was due to the fact that my computer was believe 7% battery life, but because I had it plugged in, I tried to reboot. It turned on for a few seconds but then shut off again. I tried a few times more later through the evening, but nothing worked and the same thing happened. Throughout the night my Macbook would turn on by itself (with the start up noise) and then shut down by itself continuously. It would repeatedly do it 3-4 times, give it a break, then do it again. I have been able to log on twice fully to my personal log on page, but it shuts down after a few minutes. I have tried resetting the SMC, PRAM, etc, but nothing works. I'm hoping I just have a bad battery because I have used the same battery since I purchased the computer.

My mid 2010 MBP 15" crashes while starting up. At first, it crashed while I was using it. Then when trying to start it again, it crashed when the log in screen showed up. Then when I restarted it a couple of more times, I got a screen with a loading bar, like an update was going on. When the loading bar is full, it crashes, before the log in screen shows up. I have OS X Mavericks, I think. Â
