During the boot-sequence the screen of my Imac 27" flashes green (once), then returns to normal. This does not happen when I boot my Windows (Bootcamp) partition, so I assume this is some kind of OSX driver error. This started to happen only after I installed the latest patch (10.9.3). How to get rid of it ?

iMac, OS X Mavericks (10.9.3)
Screen will go completely black for a second then back to normal display.Makes no difference what application I'm using. Within last 10 minutes went black for 4 times. Does not power down, just screen goes black.Contacted support via phone, they had me shut down, unplug power cord, then plug in and start. Appeared ok while I was on phone with support.Didn't use imac for 1 1/2 hours, now I notice it going black again.

Booting my iMac after a crash the other (leopard 10.5.6) day I came across the problem that the boot sequence would seem to hang. Visibly I would see the apple logo and the spinning bar and it would sit there. Thinking that it may be hardware related I booted up and ran the hardware diags but these showed there was no issues. I then booted off the boot cd and ran diskutil to check the os disk and that check said that the OS disk was fine. I was unable to boot into safe mode at all. I could get into single user without any problems and fsck'ing the root fs didn't highlight any errors. So with the fs ok I'm thinking that this maybe an os problem but when I boot with verbose on I see that when it hangs it gets ioerrors on the root disk rdisk0s2.
In order to prove that there was a physical problem I booted up into single user and ran a dd from the os disk and that proved it. After that preamble, I guess my question here is what should I do now ? Is there an equivilent of the Solaris format command where it could map out any bad blocks ? Or from a safety point of view should I get the disk replaced ? Or maybe I should just reformat the drive and reload the os? I'm a solaris SA by trade and on a dev box I would get format to read analyze the disk and map out any bad blocks but in production I would definitely get the disk swapped so I'm in a bit of a quandary. Also if I get the disk swapped, should apple swap it as I have had the iMac for less than 12 months?
The iMac G5 (17") doesn't want to boot up, when I press the I/O button it flashes with its white light, and then nothing happens. When I do that with the back-cover off light 1 is lit as long as the machine has power, but light 2 only flashes when I connect the pins that the powerbutton connects. I know that there was a problem with the powersupply, but the soldering I did should have fixed that.

This morning my MacBook Pro will not boot to the normal Lion screen. Pressing the Alt key during the start process I do get to the Macintosh HD, Recovery HD, Choose Network screen. The mouse moves around, the keyboard works, obviously the screen works, it appears to connect to the network.  I did notice when I double taped on the mouse pad it didn't work. What should I do next?

I created a ubuntu live disc and tried it in my iMac. So I went into system preference=> start up disc and changed the boot order in order to test the disc. Now when I booted my computer this morning it automatically went to booting from the disc even when the disc was not in the drive. I thought it should have just gone back to booting from the hard drive. Does anyone know what I have to do in order to put the boot order back to mac hd?

I tried installing Windows XP on to my MacBook running Leopard last November using an XP installment disk that came with a Dell Desktop. So that worked out well, until Boot Camp told me to print out an instruction sheet. Well, I don't have a printer connected to my MacBook, so I continued the installation without it.
The installation apparently 'finished' so I clicked "finish" but the whole installation process went back to the beginning, so I had to force quit the installation (my MacBook was running from just the disk, not 'Macintosh HD'). By the way, I went through the installation process a couple of times before I thought "this is just keep on repeating."
Well, whenever I go to boot up my MacBook now, a message comes up in a black background with white writing saying "No bootable disk, press any key to continue." Pressing any key doesn't work, so I have to hold down the power button (which I hate doing since it's apparently bad for the HDD) to turn it off, and I now have to hold down the alt/option key whenever I start up my Mac. By the way, the only disk that comes up is 'Macintosh HD', not the 'Windows HD' I partitioned earlier, which I have now deleted. My question is, what else can I do to completely erase this message I get at the start up?
I own a 17" g5 imac and today I was just browsing on Firefox and all of a sudden the screen became checkered with thin pink and white lines. It is most noticeable on the menu bar and anything that is grey or white in color. It is not checkered on the blue background behind my desktop photo. I have an external monitor plugged in as well and the same thing is happening to that monitor.

I am doing tech support for a family member, He is running OS X Mavericks 10.9.4 on a late-2009 27" iMac, and Time Machine is/was set up on a 2TB LaCie d2 Quadra V3 connected through FW800. He had noticed that Time Machine had not run in a while, so I opened it, and his former Time Machine drive could not be found. It wasn't showing up on the Desktop or in Finder, so I opened Disk Utility to see that it is unmounted. When I tried to mount it, it did nothing. I verified the LaCie drive and it returned no errors. I verified the disk, and it failed and returned "Underlying error: 8: POSIX reports: Exec format error". I tried to repair the disk and it returned the same thing. I am not sure if it has been working since he upgraded to Mavericks. It seems to me that the drive is dead, pre-reformat, but let me know if not. (I am not sure why it would have failed. He doesn't seem to turn off his computer, and I doubt he has unplugged the drive at any point. It may have been running for several years straight, though.) If it's dead, is the data likely recoverable?

New iMac at first of year has always locked up with green squares (1/4") randomly on the open window. I have to do a hard boot to unlock the screen. This may happen 5 or 6 times a day but I'm finding no pattern. It happens in any software, mail, internet browser, extra programs and only using what I need at the moment, including mail and internet, hasn't worked. I've run disk utility - repair disk and repair permissions multiple times to no avail. I've reinstalled the OS Mavericks and Adobe Creative Suite programs (Photoshop & Premiere Pro), no improvement. Â
I purchased a high-end iMac specifically to handle high-demand video editing needs. But this happens when checking email or browsing the internet too. Here's a listing of the system from a "Panic (system crashes) log" from the "Activity Report."Â

On my mid 2007 Aluminum 24" Intel Imac shows nothing but a white screen when powered on even though according to the diagnostic LED lights which are all powered on and green the logic board, video card, and everything else are speaking back and forth to each other perfectly fine. Does this mean the LED screen is bad or (from what I've read) is it a possibility the hard drive is bad? I know the optical drive is bad and will not spit out any discs. The #1 reinstallation disc for the OS is stuck inside right now. Before I order a new screen, inverter, and optical drive I figured I should ask in here to see if it is just bad hard drive or something else. Wouldn't the LED diagnostic lights tell me if the hard drive was bad?
View 5 Replies View RelatedI've been waiting for these Arrandale 15" MBPs since December '09, and in my excitement and haste I didn't assess all the options when I ordered my new laptop.I ordered the base 15" model with no changes to it, but I really need the high-res screen. 3 questions for you lovely people:1) Once I get the laptop, I could return it and change it for a one with the hi-res screen. How long does it usually take to return a Macbook Pro and get a new one back again?
2) If, once I recieve the laptop, I drove to my nearest Apple Store (about 60 miles away- I'm in UK), could I simply hand them my unopened laptop and ask for an exchange for one with a hi-res screen?
3) I noticed a hi-res, anti-glare option. Does anybody know if the anti-glare option still has that ugly grey surroun

View 1 Replies View RelatedOver the last few months there have begun to be hundreds of blue horizontal lines running across the screen and the sound fragmented, with the Mac crashing over 5 times a day. Normally, I would restart and the problem would be OK for a while.
However, now when I turn on hundreds of horizontal black/green lines appear in colums, the normal apple symbol comes up with the spinning loading item. Then a blue screen will appear and the normal log on profile selector doesn't appear. Then after a while the blue screen is covered the thousands of these black/green lines.
There have been a couple of discussions about third party retailer returns on bto iMacs and I was wanting to clear it up. I would like to get an i7 at macmall and use the $150 discount. I believe I still have to pay tax in il though. Anyways, if I get it and tere are a couple dead pixels next to each other in the center, I just have to send it into apple and have them repair it under the one year warranty right? The bad part about macmall is that I can't just exchange it out for a new one

So I brought it home turned it on, and it didnt chime but it booted to the gray screen with apple logo/ slashed circle/and folder with a "?" So I made a USB Mac OS x bootable drive (FLASH) held down alt (try using a windows keyboard its fun) was able to select option and install a fresh copy. all seemed well was running really hot so I poped of the screen. HOLY MOLY! this thing is CAKED with dust, and I am not kidding it has literally piles of dust. So I ran updates, and did firmware updates. Turned it off for the night. Â
The next morning I went to radio shack and got Dust remove spray, opened it up made sure I was carful taking off the screen, and blew the sucker out. now its NICE and CLEAN. then i made sure I plugged everything in and turned it on. Drive spun like normal, Optical checked for a CD, and fans are also running normally. but no chime, no nothing stays as silent as normal but doesnt budge, it is like it hangs. Â

there are two things that the macbook is doing to me. one is that sometimes when i move the screen up or down (the hinge is rather stiff) a white (thin) line flashes across the screen. but recently, while randomly browsing through the internet, the screen almost... i guess faded to a gray screen, but like gradually, and not like a kernel error, like the display just faded away. happened twice in a row, did a battery pull and now wont do it again.
