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 have dual ACD's. How do I make it so that both screens have the same brightness? If I adjust the brightness in the display settings it adjusts the main screen, but then not the other one. How do I make them the same?

I have an older e-mac that I use and the display suddenly became distorted and stretched. I can't see all of the words in finder or even the apple icon to shut down the computer...it has stretched far off of the display.I tried the display settings in system preferences and tried to adjust settings in geometry I can adjust the height but not the width.

Am I the only one having this bug? I have a 2009 24" iMac Radeon 4850 and after installing the 10.5.8 combo every time the machine boots the brightness is set to maximum.
I tried zapping the PRAM and that didn't help.
The other problem I noticed is that my startup network shares, even though checked to "hide" pop up finder windows at boot time. It never did this before (even without hide being checked).

Purchased my iMac 27" back in October 2011. It was fine up until around February this year until my screen brightness started flickering automatically. I have the ambient/auto brightness setting switched off and after many discussions with apple care on the phone I have been advised to bring my iMac back in to the store.Â
1) is this a common problem a lot of people have experienced with iMacs?
2) Do you think it will be repaired or replaced?
3) Does this happen with the macbook airs as I was planning to purchase one for university in September, however if this problem occurs with their laptop range then I will opt for windows.Â

After every reboot, the brightness of my iMac's screen changes to 100% brightness, which is slightly annoying. Does anyone know why this happens? By the way, I'd say it does it since 10.5.8.

I have a Rev A (Aug 2007) alum iMac (20") and ever since I installed 10.5.8, the screen has been set on full brightness on every startup. I'm currently running Snow Leopard and the problem persists. I erased and installed during the procedure so I don't think it can really be a corrupted system file or something.

The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.

My iMac's screen brightness started to fluctuate a few days ago, dimming / getting brighter. There's no ambient light sensor (as far as I can tell) on the iMac.

All of a sudden, every time I reboot, my screen's brightness is all the way up. So, I go to 'Preferences' and bring it down to only happen again the next time I reboot. Not a terrible problem, I hope, but not sure why the settings of this doesn't remain as I left it last. Perhaps I have picked up something OR I have a fault which could get worse?Anyone seen anything like this?

I know this has been discussed before, but I cannot stand that there is no option to shut off the screen. I know the Shift-ctrl-eject (not sure if I got this right, I'm at work now) works to turn off the screen, but I'm facing another issue.
At night, I frequently record shows on Eye-TV and export them to iPhone, so I can watch them during the morning commute. When the show begins, iMac's screen wakes up. When the export to iTunes begins, the screen wakes up. I tried few utilities where the brightness dims 100%, but it's not the same as turning it completely off.
Has anyone found a solution where you can turn off the display completely? Since my iMac is in my bedroom, this is a huge problem for me. I miss my Mac Mini....

My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.

I was using my mac the other day and the screen went to static real quick then gave some code to shut down. SO I did HUGE mistake I am guessing. I have only 1 user with a password. When I enter my user password it goes to a blue screen for a minute then comes back and ask for my password again. Before I crashed it was asking for permission to use fonts from my external hard drive ??? not sure why.But I figured I would just reinstall my os x and be ok... not really worried about my info on the computer everything is backed up. However when i restarted and held down the c key while it started with the os disc inserted... I came back 9 hours later and it was still the white screen with the spinning sun thingie.... like it was still loading

I have an Intel Imac G5 2.66 gHz 2 core duo running 10.6.3. I am unable to get it shut down or sleep. Choosing either results in the display blacking out, the fans run for about 1 second and then everything come back on as if nothing has happened. I've reset the Pram and Vram, disconnected all USB and Firewire devices, tried it with and without file sharing and Airport operating. A 'hard' shutdown with the power button works fine. I have checked for any firmware updates but mine is fine. This happened once before and clearing out some files from deleted apps cured the problem but it's back now.

My iMac runs perfectly fine; more or less as it did when it was new. In OS X, when I shut down the computer, the fan runs at full speed indefinitely, unless I unplug it or boot back up. When running, the fan is perfectly normal (increases speed a bit when doing something taxing). I've never heard it at full speed before until this started happening. After following the SMC reset procedure with no luck (I'd like to add that the SMC reset only says it relates to fan problems when the computer is ON), I searched a bit and noticed there are one or two cases where a problem like mine was believed to be a motherboard issue, and therefore a costly fix.Â
However, here's the fun part. When booted into Windows 8.1, shutting down the iMac does not cause this issue to occur. It stays silent, as it should, even if I disconnect then reconnect the power. This leads me to believe it's unlikely to be a motherboard issue. However I've wiped, restored, and reinstalled fresh copies of Mountain Lion, Mavericks, and Windows 8.1, and the result is still the same: if I don't want to have to unplug it from the wall, then I have to use Windows to shut it down.Â
So then, my questions are these:
-What is the difference between shutting down from OS X and shutting down from Windows?
-Is an operating system allowed/able to touch BIOS settings?
-Is it possible to still be a hardware problem, given this difference?Â
My default OS is OS X, and it makes no difference if I change that to Windows. I also did a PRAM reset, even though that has nothing to do with fans...

My mac is 6 months old has the latest OS. When I leave it playing music either in Itunes or on u tube. It shuts down to login after 15 minutes. If I am using it it does not. I have disabled all energy saving options and all "never shut down" options selected. But everytime I leave it religiously shuts down after 15 minutes.

Just recently (this night,) whenever I would unplug my main USB hub, my iMac (Late 2006) would turn off (that is, instantly shut down as if the power had been disconnected). I don't know why this happened, but it turned on immediately afterward so I shrugged it off. The last time this happened, (the 4th time,) the iMac wouldn't turn back on at all.
It responds to power button presses, and you can hear the harddrive spinning up and the CD drive whirring and fans spinning. The sleep light in front stays on, but the display stays black, and it doesn't make the characteristic chime when it "turns on". In addition, it doesn't seem to be delivering power to USB devices, so there's no way that I can boot up from a startup disc or anything to see what's going on.
What do you guys think could be wrong with my computer? I doubt my non-existant applecare would cover anything of this sort, and I'm pretty sure that i'm SOL for hopes of a computer that just works. In addition, one other question. I was working on a VERY important school assignment at the time, (cliche, I know,) so is there any way I can connect another computer to my iMac so I can get my school assignment off of it?

I have a 20" intel-based dual core Mac which i have had for about since early 2006, i haven't had any big issues with it until a few days ago when it suddenly shut itself down and refused to power back up. I ran through the checklist that Apple Support provides, including resetting the SMC by unplugging everything and waiting 15 seconds or so but none of it worked. Eventually I just left the power cord unplugged overnight and in the morning I plugged it back in.
After having the power cord plugged in for a few hours and the machine turned off, i tried pressing the power button again and to my amazement it powered back on! Immediately i ran the TechTool Deluxe software that came with my extended protection plan (now expired) and everything was fine. Later that night however, I had left my computer on for a few hours before returning to it and realizing it had shut itself off again. Now I am back to where I started, going through the checklist provided by Apple and am really starting to get concerned. Does anyone know of anything else I can do, short of taking it in to an Apple store? Or is something needed to be replaced?
