After a forced power down my iMAC won't boot again.
The machine simply powers off after the spinning gear on the gray start up screen spins for a few seconds.
I've tried booting in safe mode, doing a PRAM reset and inserting the Installer DVD but I don't even get to any of these steps and the machine turns off.

Problem: powers up, will not complete start up sequence What led to the problem: Ignorance, mostly. CD was stuck in vertical bay and I tried someone's suggestion to eject via terminal. If you are laughing (and/or groaning), you know what must have happened. Here are steps taken to rectify disk eject and start up problems, with the results. Note: iMac install disk one remains in the vertical bay, unable to be read or ejected. applejack, fsck -fy ... multiple times. Results: disk & permissions repaired and/or verified but OSX still will not start up. It starts with grey screen, goes to blue with grey window. Progress bar moves slowly from left to right and seems to reach 100%. Operation stalls at that point. Note: Any attempt to use diskutil stalls and commands such as list, mount do not execute. drutil eject gave these results: dyld library not loaded: /system/library/Frameworks/OpenGL.framework/versions/A/openGL referenced from: /system/library/frameworks/QuartzCore.framework/versions/A/Quartzcore reason: image not foundTrace/BPT trap
View 3 Replies View RelatedMy 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.

My Mini powers itself down before it finishes booting.
It's a 1.25Ghz G4 Mini, so it's a few years old. As of the last few days the computer turns itself off. So I push the power button and I get as far as the grey screen and I see the circle logo rotate and I can hear the disk heads seeking if I place my ear near the Mini. But before the OS boots, while the screen is still grey the Mini powers off. It does this with the recovery DVD in the drive too. Either way it never boots
Is there a way to diagnose this?
I've got a mac that powers up but just show a black screen? Any ideas?

I woke up to my MacBook fan going nuts. Had an error message on the screen that said something about a disk error. The machine wouldn't do anything (force quit, launch app) so I hard powered down. Now.....NOTHING. All I get is the white screen, followed by the flashing folder. Here is what I have tried so far.
I already booted from the restore cd that came with it and opened disk utility. The hard drive shows up as something like disk1 but not "Macintosh HD."Tried to repair permissions and got an error message. Thought then to do an archive and install......and the HDD isn't even a viable option to install the OS on.
I had the original (but smaller) HDD that came with my MacBook, so I put it back in and everything booted up just fine and is back up and running. (Thank God for MobleMe that had all my contacts, etc on it). But I still have some info on that other HDD that I need. I ordered a usb enclosure for the drive to maybe try some recovery, but it seems to me that the HDD failed or something. Is there anything else I can do?
Screen in complete black. Because is new maybe I am doing someting bad.

I experienced what I believe was a crash so after various attempts at doing a time machine restore, I performed an erase of the HDD and have been trying to install snow leopard from a disk I bought from the Apple store. I am not sure if the disk is the whole OS X or not as it was purchased to upgrade from the OS X that was on the machine. I am hoping to do a time machine backup to get my old programmes/software back afterwards but in the meantime just cannot seem to get snow leopard on my iMac.

I have an older MBP (1.83 Intel Core Duo) When I push the power button, I hear a little electric noise, then a fizzle noise. It won't turn on. However, if I close it almost all the way and turn it upside down, it powers up fine. Once it's running, no issues. Any idea where to start with trying to correct this problem? I don't know what part could be making this happen. And yes, it has to be both upside down and almost totally closed.
View 4 Replies View RelatedI have an '07 vintage (DVI) Mac Mini I use as a media center. I haven't used it in a few months & its been shut down during that time. I went to start it up today & the power light went on & I could hear the fan start up but no start-up chime & no video.
I did an PMU reset to no avail. I'm thinking the logic board is done (it's under warranty & I have an appt. with a "genius" tomorrow). Just wondering if there is anything else I should try before I bring it in.
Lately i've been coming home to find my imac on. I've been shutting it down due to all the thunderstorms in my area. Under the energy saver options, wake for ethernet... isn't checked off. I do run eye tv but i dont have anything scheduled. Is there anything else i should check? I have an external hard drive and printer connected to the usb ports. It's an intel imac, 5 months old, 1 gig of ram and running the latest version of leopard.

I have a 2009 macbook pro unibody, I just replaced the battery but my macbook pro 2009 powers off unexpectedly. Sometimes while its plugged in and other times when running on the battery, when it gets to 67% life left it powers down. What is causing this and how can I fix it. I have already had a brand new battery put in it. I am running Mavericks OS currently.

During Backup the sistem get stack and display into the "details window" Time machine was unable to complete the backup because unable to complete the backup folder.
This problem happens with USB and Fire Wire. The file backups.backupdb is excluded from virus scanning.
Also happens time to time that (without doing things) both the partitions of the external disk disappaire from the desk-top and a message "the disk must be ejected properly" is displayed.
This two problems are independent une to the other. I have change the backup disk but both the problems persist.

My first mini has a problem. It will power on with the light and then promptly turn off in about 3 seconds. The hard drive spins up but the fan does not turn on. No image on the screen or anything. the mini is open for diagnosis and will do the same thing if the CPU is not installed. Interesting question what will a mini do when it is powered on but doesn't have its CPU installed?

Every time that I put my laptop laptop to sleep while it is on battery, it sleeps fine for about an hour. After an hour or so, I hear the boot sound come from the laptop. When I open the screen at that point, the laptop is powered off. I have to power up the laptop. The laptop is not in hibernate mode, but has actually shut down (pressing other keys on the keyboard doesn't wake it up, I have to use the power button).
Applications start back up when I log in, however for example VMWare has rudely powered off (so I lose the state of my virtual machines), and any terminal programs that I was running (even if I just had a document open in 'vi') are also terminated.
I wonder, what causes this behavior? Is my system defective in some way, or is there an OS tweak in Mavericks to stop the computer from rudely powering off/force quitting all open apps in the process?
I've read that OS X now likes to hibernate laptops after an hour, but clearly hibernation isn't what's happening here.

My early 09 MBP just started having trouble with the USB port closest to the audio in/out. That port powers on my USB gadget, but it doesn't work. i.e. my mighty mouses laser turns on, but doesn't work. Anyone else having trouble with this?

Not sure how to go about closing these applications without being able to start the system? When I tried booting from the Macintosh HD I got a message that the boot cache partition was faulty? I have ran disk permissions etc all ok.

I'm trying to back up my new iMac to an older time capsule. But it just won't do it. The error reads: "Unable to complete backup. An error occurred while creating the backup folder".
View 2 Replies View RelatedOS X 10.4.3 IMAC Intel Core Duo. I backed up my HD on an external drive so I could upgrade to Snow Leopard. I wanted to test that I could boot from the external drive and selected it as my start up drive. When I did a restart I got the Apple and the turning gear and then suddenly a black screen with this on it:
"May 28 22:23:11 Launched:com.apple.nibindd:respawning too quickly throttling, exited system abnormally bad system call too many failures in succession I have no name!"
I tried several dozen times with no luck. I think when I made the copy of my HD on the external HD I may have neglected to make it "bootable" (moving too quickly). My internal CDROM is busted so I use an external CDROM. I can't boot from it at all with the proper start up buttons pushed. It keeps trying to boot from the external drive. If I turn the external drive off and try to boot from the external CD I just get the grey file with the ? in the middle of it.
I tried using another external HD I have with OS 10.4 on it, but it won't recognize it either with fan, alt, shift, delete pressed at start up. My internal drive (a Seagate 2 tarabite drive) works great, but how do I reset it as the start up drive when I'm stuck with this black screen. One more thing, when I try to reset PRAM I don't get a second gong.

I think i'm going to be investing in a SSD Boot drive for my 09 2.93-Octo MP. Have a few questions regarding the size needed for boot, and brand! Before I begin, I have my DL/User files on another drive already and I'm still right around 80GB in Apps, but I do have a lot of fonts and other little files Floating around that I'm sure could be moved to another drive. So
A. What size is common for boot drives SSD?
B. I'm reading better speeds in the OCZ Vertex than the Intel X25M, which drive do you trust?
Is there a drive out there with a 64m Chip thats 80g? Or do i need 120(128)to get the good chip. Also who is a good online or retail supplier for these drives? OWC?
I have started my imac today and it doesnt seem to be loading up it comes with a status bar at the bottom which gets stuch after a bit and then goes away and then nothing happens except it just keeps loading. you can see the screen I get below.
