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.Â
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.Â

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 need to complete forms on a website that requires adobe reader, when I go to the website it prompts me to download adobe reader & then click here to complete forms. I have downloaded adobe reader 3 times & restarted my computer twice & the website still keeps telling me I need to download adobe reader!Â

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.

iMAC with OSX10.9.4 ; 8GB ram ; two partitions external disk formatted MAC jurnaled ; connected via Fire Wire or USB2 .
During Backup the sistem get stack and display into the "details window"Â 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 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

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.

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?
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.

imac powers on. You come to the gray screen with the apple & the circle below it just keeps spooling around. imac at that point not making much of a sound. I have powered on & off a bunch of times. Just stuck & not booting up.

i have an old iMac8,1 running 10.5. i've been trying to run other OSes off the bootcamp partition, but i can't get it to boot off any bootable media. so far i've tried Windows XP DVDs, Ubuntu DVDs, bootable live CDs on USB drives, and even 'dd'ing a live cd to the bootcamp partition. all of these result in the same outcome: a blinking cursor on a black screen. i thought it was just slow, so i left it for a whole day waiting a couple of times, after all that it was still the same blinking cursorÂ
i also tried rEFIt, which works fine, but apparently it doesn't make a difference. both the rEFIt and the original mac bootloader won't boot anything but what's on the hard drive. oddly enough, if i boot off something that's not bootable, i do get an error saying no system found, so at least that is workingÂ

I've just bought a 27" iMac with the SSD and 1TB drive. The problem is that when i boot the machine it asks if i want to from Macintosh HD or Recovery HD.

A year ago I acquired a used G3 B&W Rev. B that had a defective hard drive. The mac will boot from an OSX 10.1.2 disc just fine, and a 40 GB Western Digital drive (WD 400) that I installed (as master) shows up and appears to format normally. However, after everything goes off without a hitch and the OS begins to install, the installation halts about two-thirds of the way through and I'm treated to a message that says the installation has failed because it couldn't "write files to disk".
- So far, I've tried this installation 4 times
- My copy of Mac OS originally came with an iBook, and I'm not sure if that's a possible issue or not, even though it's listed as compatible with my computer
- It's got a single stick of RAM (PC100 128 MB) installed in the last of four slots moving inward towards the motherboard
- I know for a fact that the hard drive I'm using is functional ( I pulled it out of an old gateway I'd been using as a music server until a month ago)
- I know that with older macs ( and computers in general) having the right firmware updates and compatible hardware installed is crucial, but I don't where I went wrong
can you boot DOS on an intel mac? Not dosbox, not a emulation of some sort, but actually boot DOS from a flash drive/ cd rom?
View 21 Replies View RelatedI have a 2009 Mac Mini 2ghz that I was trying to install Leopard Server on. I have tried by booting from DVD, a second partition with the ISO burned to it, and even an external USB drive that has a full install of Leopard Server on it that successfully boots up a 2007 iMac. I have also tried to boot from 10.5 DVDs without any luck. The symptom is consistent - it attempts to boot and then reboots about 10 seconds later. This happens regardless of whether it is a physical DVD or an external USB drive. All DVD drives and USB drives are capable of booting the iMac.
I've reset PRAM, held down option keys to select boot drives, etc. I can't try target disk mode as I don't have a firewire cable handy. Booting into diagnostic mode detects no problems for both the short or long test. The machine is just out of warranty but did have a weird problem with network where it wouldn't recognize the network connected to a Netgear 716GS switch, no matter which port. 10 other computers connected to the switch without problem. I had brought it to the genius bar who couldn't determine any hardware problems and it worked with their network just fine.
I bought this Seagate hard drive go Flex from Costco and backup my HD using Carbon copy cloner. At the time of my backup the lion version is 10.7. I am now at 10.7.2 at my internal HD although the external remains at 10.7. When I choose the Seagate HD from system preference as the start up disk you will hear the dong sound and the screen would appear but then it will shut down and the external drive would go into low energy mood. In other words the computer recognizes the external HD as having an OS but would not go through with the boot.

My iMac will not start up when shut down, or awake from sleep.To get it to start i must turn off the power, and turn it back on, then it starts up and runs fine.If i Restart it, it switches off, and will not power back on. The machine still works great but is begining to be a pain in the back-side cycling the power every morning.I have done an SMC Reset, and that did not change it.
I have also added a new user, and when i logged in as the new user, it did restart a couple of times (cannot remember the exact amount) and then when i switched back to my normal account it restarted fine... i assumed it was fixed... but after that it's gone back to it's old painful self..

I recently partitioned my internal drive with an 80 gig partition to run Ubuntu , removed Ubuntu and now can not resize hd to recover the 80 gig that I used , there was a program with this Ubuntu install called rEFIt that was installed for the dual boot , My problem is that Itunes keeps crashing and I have spent somewhere around 8 hours trying to fix this issue and in the process I discovered that I now can not boot from the osx disc but I can boot from the Ubuntu disc , what can I do to correct this issue or is there anything that I can do to correct this and recover the 80 gig that I used ?

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..

My 24" iMac had some graphical glitches and froze up, so I ran MemTest86 on it and got a number of errors reported on my RAM.Â
I had upgraded from 2x1gb to 2x2gb and kept the old RAM, so I gave that a try. This time MemTest86 itself came up with graphical glitches and reported problems on this RAM as well.Â
I gave up for the night and the following morning when trying to boot, all I get is the monitor powering up and the Mac boot sound. The system then reboots immediately and does the same thing over and over. Screen powers on (stays black though) and sound plays. I never get to a gray screen at all nor does the Apple logo ever appear.Â
Trying to boot to safe mode, off cd, single user mode are all unsuccessful, I never get out of the boot sound loop.Â
NVRAM/PRAM reset attempted, likely unsuccessful.Â
I've tried booting with 1 DIMM and 2 DIMM across the different RAM I have, but the same thing always occurs. Only time I get different behaviour is when booting with no RAM, and then I just get a beeping tone.Â
I have a probleme since i got my Imac 27 Mid 2010. It just dont boot when a usb Drive is plugged in. I had i Firewire hard drive in the past and i had no problems to boot up on it. Turn the mac on, holding option key and bang ! BUT usb just dont work, it stay on gray screen and after a while (10 mins) it boot on my regular internal drive.Â
I tried several usb drives and it's always the same. It look's that im not the only one that have this problem.

Odd problem that just started with my 2008-ish iMac. Probably not related, but iTunes did it's typical thing of hard freezing my entire system. I hard rebooted my iMac, and it rebooted with no video. It chimed, but the screen remained black. I searched for the problem and found an old Apple article that suggested resetting the PRAM. Not really believing it would work, I tried it anyway and, still no video.
I let it boot for what I believed was a reasonable amount of time to get to the log in screen. Then I hit the F-buttons for volume and received the chirp letting me know that I was changing the volume. I hit the F-buttons for brightness, but did not get anything from the screen. I was working, so I shut it down again, let it sit, and started it up later. Video! It started up just fine. I know it probably needs to go to the Apple Store, but I am not going to be able to get down there for a day or two.
