I sign in and when Safari opens, whilst Microsoft Messenger is downloading, the monitor screen vibrates between Safari and Messenger at a very, very, fast pace. Back and forth, back and forth, alternating between the two. When the booting process is completed the computer is fine. Everything is OK. Any know what is causing this, and what to do about it?

iMac, Mac OS X (10.5.8), 2.4 GHz Intel 2 Duo Pen
I've got a seagate 7200.4 500gb hdd, although it is fast. It vibrates a lot in my mbp. Has anyone else experienced this? I'm thinking of swapping to a 640gb 5400rpm hdd.
I recently bought a Seagate Momentus 7200.3 and built it in my white macbook.
The performance (opening aps etc.) of the macbook is significantly better and the 320 gig are also great.
The only problem is that the case vibrates constantly.
By pushing with only two fingers on the right side of the case (near the touchpad) the whole vibration stops.
When I boot I get a full black screen, and:
/etc/master.passwd: No such file or directory
/etc/master.passwd: No such file or directory
-sh-2.05b#
I have tried fsck -f and it runs, I get the response The volume Macintosh HD appears to be ok I type "reboot" and it starts rebooting again and I get the loop of:
/etc/master.passwd: No such file or directory
/etc/master.passwd: No such file or directory
-sh-2.05b#
Is there any way of fixing this problem? I am running OSX 10.3.9 on a 17" iMac.
I've had this 2.0 Ghz 1gb ram Macbook since September 2007 and this was the first time I've ever had any problemas with it. So let me start from the beginning.
It all started this year. One day I picked up my Macbook and turned it on and I noticed that the screen was blinking quite a lot... then it started to get worse to a point I got really worried and it started to annoy me. Sometimes I'd boot it and Leopard would be changing my wallpaper every second (it's supposed to change my wallpaper everyday according to what I've setup in system preferences). While blinking the colors would get messed up and when I closed the Macbook and let it on, sleeping, I'd open it and it would be on the blue screen as if I had just turned it on.
It's worth mentioning that I was running a version of Leopard I downloaded from a torrent and had installed it from an external hard drive. So I thought I should try to format the machine, erasing everything and installing a new and original version of Tiger. Once I installed AND got all updates installed as well it was running perfectly. The blinking had gone away.
Yesterday I installed some new updates, booted and used it fine. Today I turned it on and it won't go past the blue screen and the apple logo won't show up as well. My Macbook just won't boot... I've tried booting on safe mode, booting with the tiger dvd on, i've tried resetting the pram and everything else I could do. The apple logo won't seem to appear and the machine won't boot.
First the blinking screen and now it won't boot.
Any other suggestions besides taking it to a support store? It's worth mentioning as well that I live in Brazil and support to Apple computers isn't as great and cheap as it is in the US. I've had this Macbook for less than 1 and a half year.
When I turned my iMac on this morning (iMac G5 PPC 10.5.8) it went through all of the "normal" steps (gong, grey screen, apple logo, progress wheel, blue screen) and stopped at the blue screen. Thinking it was just a fluke, I shut the machine down and restarted, only to have it stop at the blue screen again.
After disconnecting everything going into the iMac except the keyboard and mouse, I attempted to boot into safe mode but it stopped at the blue screen again. I tried single user mode too but I didn't get any further than the blue screen.
Next, I flashed the PRAM (big gong, single quieter gong) and afterwards it came to the blue screen.
I reattached my external drive and selected to boot from a 2-day old backup. Using the backup I was able to log into both my regular account and my "test" account (without login items).
I have a two and a half year old mac book. It's not booting further than a white screen.
What has happened I think is that it was run flat. I have though charged the batteries up to two green lights on the battery.
It's making hard drive noises but sits on the white screen.
Any ideas. This is my main work machine and I rely on it.
A few times now, maybe once a month, I've restarted my (first generation, 2006) Macbook and gotten nothing but a black screen, while the computer seems to be continuing to boot in the background. The boot-up sound plays, and if I leave it to finish, the screen goes from black to a dull grey, and I'm able to shut it down by hitting the power button and pressing Enter, as if the shut-down dialogue screen has appeared. The pattern so far seems to be that if I shut down down mid-boot, by holding the power button, the next boot will still have a black screen; but when I let the boot finish and shut down from 'within' Mac OS X, the next boot works normally. I restart the computer once or twice a week, and this only happens occasionally--but it has been happening repeatedly.

I'm trying to boot a relatively new intel iMac. I can boot to a blue screen, in which all that happens is the music that happens with the welcome video of mac OS X.
I currently have no keyboard to do diagnostics with because I don't have the wireless keyboard that came with the mac, nor a wired keyboard. I'm planning on borrowing a simple wired keyboard to use to diagnose the mac in verbose mode and safe mode etc.
The owner of the mac has done a complete reinstall, hence the welcome video music, and that hasn't worked, as the screen shows no sign of anything other than blue.

I have a 2005 G5 PowerMac. It has been locking up lately. Tonight it will not boot. Everytime I turn it on I get to the apple screen and the circle keeps going round and round. I then followed the directions to reset the PMU and I disconnected the second hard drive. Now it will still not boot and gets to the apple screen, circles a couple of times then locks up. I have disconnected everything except the monitor, keyboard and mouse and still have the same problem. The largest issue is the CD drive will not open so I cannot attempt to reload the OS or anything else that requires the CD drive. I do not know if there is a manual way to open the drive. I have searched the help forums and only see the keyboard as an option. I have read many posts that the 9800 video card is a problem - we have an ATI 800 XT and I have not read anything hear about that card being an issue.

Yesterday I installed the latest security updates for my ibook via software update. I'm not sure if this is related to my problem, but I thought I might as well mention it. A few hours after installing the updates, I turned on my computer. Everything was running fine, however as I was listening to music and surfing the internet, my screen turned black. I checked the contrast and it was all the way up. The screen then turned completely off. Upon restarting the computer, my screen got to the loading page with the apple icon and the loading circle, and then turned black and flickered every so often with a screen of vertical multi-colored bars.
I held down the power button to turn the screen off, and the flickering increased, before becoming completely covered by the multi-colored bars and then shutting off. This morning I tried again and my computer actually booted up. However, after a few seconds the screen went black, paused for a few seconds, then went completely red, then green, then blue, then three shades of gray, and finally black again. It repeated this cycle twice before the screen turned itself off. Is this a virus, or hardware/software malfunctioning. I've had my ibook for two years.
I'm on Mac Pro os x 10.5.4 and having a problem with my computer waking up from sleep or as it is booting up.
As it wakes up from sleep, the screen becomes blank or shows weird, pixelated bars all over the screen. When I try to move the mouse or press something on keypad, the computer freezes after and I would have to force shutting it down by pressing the power. It doesn't always happen, but quite often these days.
Also, when it's booting up, it sometimes will freeze with a blank screen in the middle and won't show the desktop.
Everything worked fine until a few days ago, and i'm wondering what's suddenly causing this problem.
I have an MBP about 2 yrs. old. This morning when booting up, the computer made the chime sound and appeared to turn on but the screen stayed completely dark. I tilted it around and tried to see if the backlight was just dead, but there appears to be absolutely nothing on the screen. Furthermore, the little light that normally pulses while the computer is sleeping is on, though not pulsing, anyone know what's going on?
View 4 Replies View RelatedI just installed Snow Leopard on a white MacBook. Everything was fine until I went to Update the rest of the software on the computer. I hit "Install 11 Updates", it started installing, and then it just turned off. I powered up, hit the update button again, it began downloading and then powered off again. I plugged in power and powered up and now im stuck on a blue screen with the black spinning showing up and hiding repeatedly for 5-7 seconds at a time.

I got to the disk utility and it freezes. I am stuck using my bottom of the line laptop untill I can work around this.

View 3 Replies View RelatedI have a 10.4 iMac. Recently when using it the screen starts to pixelate with large random squares and effectively makes the computer useless. Either that or I get moving multicoloured flashing squares (very psychodelic)Also on booting up the grey screen with the apple logo has dark grey sqaures and then when it goes to the blue screen has a series of smaller squares top and bootom. The booting up stops at this point.
I have ran the disk doctor, but it doesn't seem to have made any difference.
When I try to boot my Mac G4 the light comes on the cd drive will open but nothing else happens. No chimes or screen image. I haven't used it for a couple of months but it was working then.
View 1 Replies View RelatedI just purchased Windows 7 to dual-boot on my brand new 2010 MBP. After I installed Windows 7, I inserted my MacOSX Snow Leopard install DVD so I could install the drivers. A message came up saying "This installation isn't compatible with this computer". So I restarted my computer and when it was booting up it gets stuck at the grey screen with the apple logo and rotating wheel. After a while a grey curtain comes down with a Power Icon in the background and a window saying "You must restart your computer" in a variety in languages. I tried restarting and the same screen comes up every time. I've tried all the boot key commands such as holding shift. But each time it doesn't recognize it and proceeds to the grey screen of death. I'm completely stuck here and need help ASAP. I would like to do a hard reset on my MBP, but I can't since I can't boot to MacOSX and when I boot to Windows 7, it runs for about 2 minutes and completely freezes, causing me to force restart.

I Upgrades to Lion last year. Two months ago, suddenly the screen of the iMac went black. I tried to boot but it didn´t. After waiting one day, it worked and i made a backup and I installed Lion again but this time not updating.It worked, never happened again till yesterday. The screen went black, I still could listen to the song that was playing on iTunes but after a while it crashed at all.Hours later could start the computer doing everything i read here: SMC, PRAM reset, start with D, with shift.... and i made the backup but when i was going to install Lion again it went black again and I couldn´t restart my iMac.I´m afraid it´s the NVIDIA card, but i can´t be withouth the computer some weeks. Is there anything i can do to fix it or to boot at least?

I had to shut down my Mac Pro Server to move it & when I turn it back on it came back up to the log in screen. I went back into the server closet to marry an iPod Touch to it & the Mac Pro was off. So I pushed the power button to turn it back on & now it doesn't get past the Apple screen.

My MBP was working fine and then froze while I was on the internet. I turned it off and on again by holding down the power button. It powered on and froze on the white/gray screen with the Apple logo with the spinning wheel underneath it. I restarted it again by holding down the power button. Now it freezes on an all white/gray screen. I've tried starting it with the disk in it and holding down the "C" key and starting it and holding down the shift key after I hear the start up tone. Neither have worked.

My macbook pro late 2009 (10.6.7) when i press the power button it turns on, then it turns off by itself and then on again and gets a black screen and nothing more no booting sound and i just hear the fans or the Hard Drive going...

I recently received a friend's iBook (G4 - not sure about other specs) and it isn't booting. The computer just hangs at the Apple logo when I try to boot from the hard drive.
So I decided the easiest way to fix it would be to simply take my retail leopard disc and install it on the machine (they don't need any data recovery). When I hold the option key the Leopard disc shows up fine, but after I select it and click the arrow to continue it just sits at the apple logo with a twirling loading icon. Anyone else had this issue? Any ideas?
Do I need to reset the system profile or something? Sorry I am an old-school mac newbie... my own machine is a MacBook and I'm much more familiar with it than this G4 iBook.
I recently purchased from a friend a Powermac G4. It was running Panther (i Think). Because it wasnt running all too well, I decided to give Leopard a go.
I had an extra copy of Leopard lying around, so I installed it. It booted up fine, and was working, until I restarted the computer. Now it doesn't boot up at all, and I get a grey screen with a folder with the mac symbol and a question mark on it. What have I done? And how to I fix it?
I know this has been somewhat covered before but.Should I be booting into 64-bit Snow Leopard?I have a 2008 Mac Pro with 16GB of memory.I mostly run Photoshop CS4, X-Plane, QuickTime 7 Pro, Compressor and FCP6.
I know you hold down the 6 and 4 keys but is anyone using either "Happy Cat", "K64Enabler 1.0.1", or "32- or 64-bit Kernel Startup Mode Selector 1.2.3" to enable 64-bit Snow Leopard?
I have mac osx 10.5 leopard. I shut my mac down to move upstairs, then when I went to boot up again it didnt start. So I got the leopard cd and hold "c" at start up and it still stays at the grey screen!
I remembred a few hours prior to shutting down Imoved some of the default os x applications into a sub folder in my applications folder ( isync, address book, capture, etc). But this doesnt seem like that could of caused it?
My ibookG4 is loading to a blue screen. It will not boot in safemode, so I am booting in single user made and running fsck. I have run fsck about 10 times, and it keeps saying that modifications have been made, but has not yet come back clean. I have also tried several other methods. All i've gotten is blue screen.
View 1 Replies View RelatedHere is the situation. I have a 12 in Powerbook G4 with OS X. About a week ago I downloaded a security update and once it was downloaded it asked to either restart or shut down the computer. I clicked restart. It shut down and then turned back on but only got to the Apple symbol with the small grey spinning wheel beneath and wouldn't finish booting up past that. I tried turning it on while holding down the option button and it went to the hard disk screen and clicked the right arrow but it still didn't get past that screen.
