IMac (Intel) :: White Screen And Thunderbolt Icon
Sep 7, 2014
I have a new MBP. I was trying to transfer stuff from my iMac to the new MBP using a thunderbolt cable and pressing down the 'T' key while restarting my iMac.
Long story short, there was not enough room on my MBP so I just continued on without transferring anything. Disconnected the thunderbolt and my iMac is still on a white screen with a floating thunderbolt. How do I proceed?

I was off of my iMac for an hour or two so my screen saver when on. I went to wake the computer and it was frozen. I tried using the keyboard and mouse to wake up the computer from the screen saver, but it would not work, so I powered the iMac down manually from the button on the back. I let it sit for 15 minutes, then I tried to start the computer up again. Now at start up, I get to a blank white screen with the spinning moving pin wheel, and that is it.

So my 20" 2.4 Imac crashed on me twice tonight. A box popped up telling me to hold down the restart button for several seconds to restat. The second time I did this it just sits with a white screen and give three loud beeps over and over. Is there a fix for this? Is it my ram? I'm at a loss.

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?

Why is my Snow Leopard OSX 10.6.8 IMac screen all white when I turn it on? There is no spiral and no Apple logo and the desktop does not appear. The screen is just white.
Prior to this, we had a wind storm in our area with some power glitches today. After one of them, the dock items disappeared and just the wallpaper was there. The colored spinner began going around when I clicked on the mouse but nothing was happening. I unplugged it to try to reset it, but now the screen comes up all white, there's no apple logo that appears at start up and that's it. Now what should I do?

Macbook Pro 15". Product #: Z0GG
Backstory: Sunday the updates window popped up so I let it run and reboot. Boot screen is stuck on the white screen with apple logo and spinning icon. None of the typical hotkeys were working like the Shift key to go to Safe Mode. I decided to resinstall Snow Leopard which went perfectly fine since I was able to boot off of the Install DVD. Everything seemed fine after the install and I had all of my previous programs and files.
It worked fine all day yesterday until I shut the lid to leave work. I got home, opened the lid and the spinning mouse icon was continuously spinning. I could move the mouse but couldn't click anything. I shut it down using the power button. Upon booting it up I did not hear the boot up sound but a white screen displayed and didn't do anything from there. I rebooted it again, inserted the Snow Leopard DVD to try and boot off of that and it won't even boot off of the DVD. None of the typical hotkeys work either, not even to eject the DVD. I do hear the DVD spinning up but it doesn't do anything; just a white screen.
I did reset the PRAM which forced it to reboot and I got the startup sound back but it still only shows a white screen. Any ideas? I forgot to purchase Apple Care last month before my 1 year warranty ran out so I'm 1.5 months out of that.

I have a 21.5" late 2009 iMac with thunderbolt 3.06 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3, Nvidia GeForce 9400 256MB, running OS X 10.8.5
Brought a new 4TB thunderbolt G-Drive. And, my iMac doesn't see it and the hard drive doesn't even power up. Tested at Apple before I brought it home.

I have a new iMac purchased in Q1 2014 and connect my G-Grive to it via an Apple Thunderbolt to Firewire 800 adapter. My iMac runs 24x7 and this FireWire 800 hard drive connection drops out on a regular basis - I'd say maybe once every week or so leading to a dismounted drive and an unavailable iTunes library. I have a slightly newer USB3 G-Drive which is connected by the USB socket next to the TB socket on my iMac. This one doesn't drop out/dismount. I cannot tell if it is a software issue or a physical (cable movement issue), the plug has never been out and I can't deliberately disconnect it at will by wobbling the cable/plug.
So, evidence and experimentation suggests the physical connection is not the issue. This problem has only come about after switching from a physical FW800 connection (my old iMac) to working via a TB adaptor (my new iMac). I'd rather not replace with more USB3 G-Drives (lack of free ports) and I'm not sure if I want to invest in a TB drive if the connections cannot be relied upon. I've seen lots of complaints of TB-FW800 connections dropping on MacBooks but did not see a specific solution. .

This is perplexing me: I've only had my iMac 21.5" for a week. I posted here about the white screen issue after the 1st s/w update. Now, on every restart I get the same *but only when* my USB ext HDD is plugged in; unplug it & it starts fine, plug HDD in and it mounts, checked external HDD with disk utility - AOK. Never had this problem with my old 20" iMac! It's still in DoA period so is it best to get it swapped out?

I ran software update and got (iPhoto, itunes, Security patch) so I ran it and downloaded everything except the Intel Security Patch. So I restarted and decided to try again. Restart didn't work as it got stuck and I had to reach around and restart by holding down the power button. When it came back up, I got the white screen with the grey apple logo and the spinning clock like icon..... spinning and that is where I am stuck, left it off all night and tried it in the morning, same thing.
I did try:
-resetting pram (nothing happened)
-restart in safe mode, holding down shift key (nothing, stuck on screen)
I would try to start up from the OSX disk except I have a DVD in the machine. I am thinking it was that security update that didn't download fully that is doing this but how do I get the imac, "unstuck"? or how do I manually eject that DVD to put in a OSX start up disk?

Three times in the last week or so my iMac's screen has just turned white (once with almost a ribbed pattern with thin grey vertical stripes evenly interspersed) and become completely unresponsive, with the only option being a hard reset. It's happened under a variety of conditions: while surfing in Safari, while working in Aperture, and once without doing anything (I was on the phone sitting by my computer). Each time I've restarted it everything seems to work fine for a couple days, but then it happens again. I've never seen anything like this and I figured after the third time it's time to ask for help. Does anyone have any ideas?

I've been researching for a while on upgrading my white intel iMac from a "Core Duo" processor to a "Core 2 Duo" processor. The processor I would like to use is a Intel Core 2 Duo Mobile T5750 processor, which would give me 2 additional cores as well as a small speed bump from 1.83 ghz to 2.0 ghz. I figured compatibility should be fine considering the FSB speed (667 Mhz) is the same. Has anyone tried this? Can anyone tell me if this will work for sure?
