Intel Mac :: Won't Boot Up From A Shutdown
Mar 29, 2012
Tried to start our iMac get the normal chime, then the gray screen with the gray apple......but then I get a narrow progress bar on the bottom of the screen. The progress bar in the screen gets about 1/8 filled and then it disappears and then I get a second bar ant it also gets about 1/8 filled and then the computer shuts off. I did try to do a reset of the pram ( only thing I could think of) ...did not work. Fortunately, I have Time Machine..

I have an issue with my 13" Macbook pro mid 2010 OSX 10.9.3. It won't boot after restart, but boots normaly after shutdown and start again.Â
Few months ago my primary sdd Corsair hard disk (I have 2 hdds. Replaced the original with the CD-rom) which I installed 2 years ago, stopped working. Gave the macbook to authorised service provider in my country and they said I need a new hdd and a new hard drive cable. The ssd was still under warranty, so Corsair replaced it with a new one. They gave me SATA3 instead of SATA2 (which at first I didn't noticed). Later they said they don't have SATA2 anymore. Also replaced the broken cabel.Â
Now it's working. If you start it after normal shutdown, it boots normally. But if you restart it it won't boot at all. The apple keep spinning and the forbidden sign appears. I tried PRAM and SMC reset. Nothing
What should I do? Can the use of SATA3 instead of SATA2 hdd lead to some issues with my macbook? I can try to find and buy new SATA2 sdd hdd but they are expensive and I'm not sure it will fix the restarting issue.

I am running Mavericks 10.9.3.
I always quit out of all apps before doing a shutdown. I make sure that nothing, except Finder, is running when i shutdown. And, I do a full shutdown, not just sleep. Â
Yet, occasionally, the apps that were running before I quit out of them will restart when I turn the MacBook back on.Â

iMac will not shut down when I use the "Shut Down" feature. My cursor just keeps spinning in the centre of the screen. I realize I can just power off with the button on the back of the screen but I don't think that is the best way to go about it.

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?

My iMac doesn't turn off in the normal way any more. The system shuts down and the screen becomes black, but the fan keeps on running. And it deosn't stop! The only way to completely shut down everything is to hold the powerbutton.
I already have reinstalled Lion, but the problem is still prensent. I've got this iMac for around 6 months now, but this problem occured around 2 weeks ago. Before everything has been all right.

My IMac does not shutdown through the normal operating procedures. I have to press the reset/shutdown button in the back. Plus it constantly freezes up. I have over 100GB of free space. Total capacity is approx 500GB

When I had just installed the Intel X25M (80 gb G2) shutdowns took merely 2 seconds. Now, after the dock minimizes adn hte icons disappear, the computer just hangs for 10-15 seconds, turns into a blue screen and hangs for maybe 10 seconds more before actually shutting down (black screen, everything off).
Does anyone know what is wrong? The drive is only 2-3 months old, and I still have 40 Gb free.
I was thinking it is some program that is running in the background that is having trouble quitting.

How does this work? If I have more than one user logged in, the power goes out and the computer decides (based on the settings I have selected for UPS) to shut down, will it be able to complete the shutdown? When I do it manually I have to log out the other users.

I have a 2011 iMac which i've loved using. I bought a Seagate goflex external harddrive so I could start using time machine. I've noticed that whenver I power my iMac down it will sit on the grey screen just before shutting off for a long time. In fact, it will not actually shut down until i unplug my external hard drive. As soon as I unplug my harddrive the mac starts thinking again and shuts down within seconds. Why it would do this. I now hard plug my harddrive in because of this, which is kinda of dumb since I bought it to work as a time machine.

Is there a way to manually lock an iMac screen? Like you can on Windows' PC's, I'm wanting to type or click a function to lock my screen and go to the log-in screen instead of waiting for the alloted time to run out.Â

Usually when I shut down the system using the software "shut down" command, the system shuts down. Lately, I have had to use the shut down button which resuts in an improper shut down when I restart the computer. So, there is a software glitch. Is there anyway to correct this?

My early Intel iMac (2006) won't shut down - gray spinning wheel and blue screen for more than 2 hours now. Can I safely turn it off with the power button? (I'm a little paranoid after a bad experience doing that with my MacBook Pro).what I should I do then?

My iMac is the latest model, however when I try to shut it down I get a grey screen with the apple loading spiral and it doesn't shutdown. I have version 10.7.4 OSX Lion, all updates have been downloaded. I have resorted to leaving it on. I do not want to hard shutdown because this could damage the system, my old iMac broke after the hard drive was damaged with the same style of issue.

I have a mid 2007 iMac that seems to, for no apparent reason at all, just randomly go to a blank screen, locking up my Mac requiring a hard shutdown. This happens sometimes right after I start it up or after I'm on for hours at a time. Or not at all, I simply don't get it. I reinstalled Lion (after I redownloaded it to be safe) and it didn't seem to work.

My mid 2010 iMac i7 will not boot past the apple logo? I'm running 10.7.3. I have tried restoring from TM backup from recovery mode (worked the last time this happened) however upon completion it returns to the recovery screen? I made a disk of Lion when I downloaded the first time (followed same instructions sourced from numerous websites) which does not seem to work when i set to start up from this disk, just gets to the grey screen and flicks between the apple logo, a folder icon with a question mark and the circle with line through? Now I can't eject the disk either, a message appears that system can't eject and to make sure all applications are closed? 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. Â

OS 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.

My iMac was working perfectly till two days ago, I shut it down normally, but haven't been able to start it since then. When I press the start button I can hear the HD and fans working, and also the USB ports are powered, but screen keeps black and no boot tone.Â
Since I have a bluetooth keyboard, I am not able to start in safe mode..

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?
