I just bought a iMac M5521 from a friend and it won't boot. It looks like it's about to start up and then it goes to a gray screen and tells me to press the reset button or hold the power button, and it says that in like 3 diff. languages. What do I do? I'm a PC guy and know nothing about Macs.
View 3 Repliesmy dual 2.3 ghz G5 power mac with 3.5 gig memory running 10.4.11 started crashing (grey screen "you must restart your computer...) and soon stopped booting. suspecting the hard drive as it had been noisy for some time I ran "repair disk" in disk utility from my mac book (connected by firewire, G5 booted as target) and it booted again but soon crashed again and after a couple more crashes it would not boot and attempts to repair failed. I installed a brand new hard drive, installed osx 10.5 and updated it to 10.5.8 and it seemed to install and boot fine but while trying to burn a .dmg dvd with toast (10.0.5) I got the grey screen anain and repeated attempts to burn a disc with the same .dmg resulted in a crash every time. it has also crashed while downloading, playing back itunes hd video, and using an "eye tv hybrid" tv tuner as a dvr. below is the most recent crash log - note that most of them have referenced cpu 0 although the most recent it's cpu 1 -THANX & PLEASE HELPInterval Since Last Panic Report: 0 sec Panics Since Last Report: Anonymous 4A58CF1E-844-409F-8BF3-65A3A3CD2E79.......
View 2 Replies View RelatedI'm frequently getting the problem that: many times the screen goes grey and a message box appears telling me that I have to restart. Often this is preceded by the fans gradually increasing in speed until they are runing at maximum speed. BUT the fans behaving that way is NOT due to overheating. I have to use the restart button to make the Mac restart. I have used reset button to reset the motherboard but that did not cure the problem. Anyone have any ideas about how to cure this problem? I'm running 10.4.9. The mac is a dual 1.8 (June 2004). 1.5GB RAM, two SATA internal HD�s (Maxtor), two external firewire HD�s (Seagate). All the HD�s are less than a year old.

I started up my iBook today and it took me all the way through sign-in to my desktop before giving me a grey overlay with a little box saying that I need to restart. So I did and then it took me to my desktop again before scrolling code across the screen in a very messy, un-mac-like way. I tried getting into safe boot (restarting and pressing shift from after the tone until the apple and wheel show up) and it just ran the apple and wheel grey start-up screen for a while before kicking back into a normal restart and giving me the earlier results. So I went and got myself into single-user mode and ran the fsck -yf command. It told me this: Checking Catalog file Invalid extent entry (4, 190) Volume check failed Is there any way to fix this, to save my computer? I don't know anything about code or computers. My general mode of operation has been "I bought a /mac/. I shouldn't ever have to look at code."

I 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.

View 24 Replies View RelatedAfter installing updates, I restarted my Mac and it ends up with a matte gray (cloth-like appearance) with a gray Apple logo, but does not get to the desktop. I can open/close the DVD tray, and have cursor control, but nothing else seems to work. Short of reinstallation of Snow Leopard, what are my alternatives. I did the Lion update online but do not have a system disk, hence reversion to Snow Leopard is my only option.Â

Im new to these forums. I have just (5 months) purchased a new Macbook pro. I have upgraded the RAM to 4GB, but only recently since ive been in Canada (1 month) experienced this problem. The screen goes grey once a day and the computer asks me to restart the system. I believe its called a Kernal Panic. Ive read on other places that it might be caused by recently installed apps. But i have got rid of these and now nothing has changed! I havnt got my Install CD on me therefore cannot run a reboot. Im not sure if the issues are related but the Mac also kicks me out and makes me log in again. this doesnt happen as frequently but is still concerning and rather frustrating.

A friend of mine brought over his 14" iBook G4, 1.33GHz, 60GB HDD and 1.25 GB RAM. The problem with it is that upon start-up, the grey screen with the apple/turning gear comes up, then after a few moments a blue screen will appear, though no box showing the start-up process. I've run a few basic diagnostics on this, including the lovely disk utility (which did nothing), I've run fsck, zapped the PRAM, etc, no success as of yet. At one point, I received a screen with alternating folders, one showing the smiley mac face, the other folder with a flashing "?". I cannot replicate this for the life of me. I have attempted to acquire files via TDM, though am not able to see the hard drive despite using 2 different laptops. Possibly the firewire cable itself is spent, though it's brand new! Here is where I become increasingly frustrated: I ask my friend for the boot disks as the ones for my own 12" iBook don't work (for whatever reason). He tells me that he loaded Leopard this summer (currently running 10.5.2, no updates loaded since), then proceeds to bring over boot discs for a MacBook...:headdesk: To begin with, it seemed like the HDD was fried, however, after running disk utility (and not hearing any negative sounds), it does appear that the HDD is fine. I'm thinking a kernel panic, though not sure how to resolve these.
View 11 Replies View RelatedThis started happening around the beginning of this year. I contacted Apple Support and they worked with me on-line and over the phone. It happened again the next day. After it happened about 20 more times, I took it into the Apple Store and they decided to reinstall the OS. Since then, it has happened about 10 more times. Â
This has happened with and without attached devices or flash drives. It has happened on different wi-fi networks. It generally happens when I am navigating with the track pad or with a mouse. I don't recall ever leaving the room and returning to find the gray screen. In other words, it happens shortly after I have moved the cursor. I've noticed the pinwheel usually appears before the gray screen.Â

In fact I'm getting a grey screen when I just try to restart. Have run Disk Utility (which always finds Permissions errors - even though it appears to make repairs. Also, after erasing my hard disk and recovering my user data from Time Capsule). When I restart I don't get beyond a grey screen (with moving cursor). I can't install the update as obviously I need to restart in order to start the install process.

I turned up one day to teach using the Mac Pro and the message on the screen said I had to restart my computer. After many times I gave up. I wrongly thought the hard disk failed as one of the pupils saw some water underneath the Mac from the leaking roof. I checked and formatted the hard drive inside a pc and put Windows on it. After inserting the hard drive and the OSX into the dvd drive proceeded to re-install the software, only to find exactly the same problem as before. What to check next before trying to find someone to fix it.

so i restart and now i have a blue screen, with nothing on it, i'd let it sit for about 15mins then it goes to a black screen that has my computer name and asks for login and password info.
So last night, my Macbook started to show a folder icon with a question mark on it when I tried to boot it up. I tried to restart a couple different ways, using the Install disc, and when nothing worked, decided to reinstall OS X entirely.
Well, after the first disk finished installing, it said to restart the computer and be prepared with disc 2. Unfortunately, after the restart, I just get a blank gray screen, while my optical drive makes short repetitive noises.
Any advice on how to get the reinstall to work right?
