Mac won't start - start up wheel is running and running. Any ideas?!?

I tried to install latest flash player. My mac hang up and did not install the programm. I had to show it down and then the mac came back. Only thing showing is the start up wheel... I need help :)

Please restart your Mac and hold the 'Option'-key to see your start-up discs. If you do not see any start-up discs it could be your hard disk cable that is faulty. This is a common problem with Macbooks, but I am not sure this issue has been fixed with the Retina models. I've had this problem with my 2012 Pro, and a new cable did the job. Very easy to do yourself!
You can also start Internet Recovery (need wifi or cable) and start up Disk Utilities to see if your hard disk shows up there.
Please let me know.

Hi Patrick,
Can you please mention the version of Adobe Acrobat that you are using and on what OS version. Also mention whether this problem has started recently and was running fine earlier or is it a fresh install and has never worked for you.
Have you tried uninstalling and reinstalling the product after you started facing this issue.

The 5 second timing is important to a successful reset.

Hey treasure hunter,
I found some help for when your computer won't turn on. Try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.MacBook Pro: How to remove or install memory
Reset the SMC.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).
Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

If it still does not work, Restart using your 10.5 Install DVD as the boot volume holding down C from chime sound to apple logo appearance, then after selecting your language from the menu bar go to Utilities > Disk Utilities, and run Repair Disk on your Mac's HDD. Afterwards, exit DU, exit Install, restart normally.

I Mac won't start -- we get apple logo with spinning wheel, question mark that disappears and then a blank blue screen

My daughter's old I Mac won't start. It is not backed up. We want to get some things off of it if we can.
When we turn it on, we get the Apple logo with spinning wheel for awhile, then a question mark briefly and then a sky blue blank screen. Is there any hope of getting this to work? This computer is out of warranty. Does it seem that if we reinstall the Operating System we might find old data?

First try restarting with the original install disc an run Disk Utility to repair the drive. If you have to re install the OS make sure you select archive and install or else everything will be lost.

Mac won't start (Kernel Panics)

Hello,
My mac won't start up. It turns on, gets as far as the spinning circle and apple logo then a dark screen comes down with a Kernel Panic message. This occurred roughly three months ago and I ended up taking the mac into the regent street store where it was fixed under apple care warranty. My care has now run out, and the 90 day repair warranty has expired but the problem is back so obviously hasn't been fixed properly. Is there anything that can be done about this?
Every time I boot up the computer the message appears, I have tried rebooting with the safe option as well as re installing OSX from the original disks. The install completes successfully but upon restart it pops up with the original kernel panic message.
Luckily I have everything backed up so am prepared to try anything to get it running.
Thanks.

Let us know, but since you obviously have another machine, have you tried Target Disk Mode and then Disk Utility?
use TDM to access Disk Utility.
1. Click the First Aid tab.
2. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
3. Select your Mac OS X volume.
4. Click Repair. Disk Utility checks and repairs the disk.
Please post back,

Have you just tried repairing with Disk Utility?
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

Your Mac won't start up in Mac OS X (Mac OS X 10.3.9 or earlier)

I just got off the phone with an AppleCare agent. My iBook OS 10.4 wouldn't start - it just went to a blue screen. I'm happy to say that the agent got everthing working again and said that she would email me an article that would help if it ever happens again. She emailed me "Your Mac won't start up in Mac OS X (Mac OS X 10.3.9 or earlier)" I have 10.4, is this article any use for me or was I emailed the wrong articel. Is there an article "Your Mac won't start up in Mac OS X (Mac OS X 10.4 or later)"????

Thank you for yoiur response. I'll click on that link and add my input..
Don't be put off by the title. The document's just as
valid for Tiger, especially if those are the same
steps that fixed your problem. The article was
revised Feb 2006 and someone forgot to update it to
mention Tiger. Go to
<http://docs.info.apple.com/article.html?artnum=106464
, click on the It's good, but... link and
tell them it should be updated to include a reference
to Tiger.

Mac won't start blinking folder with ?

Hello have a question, my mac won t start, it appears a folder with a ? Inside....can anybody help me.....

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

Mac won't start after failed OS upgrade

I attempted to upgrade from Leopard to Snow Leopard using an installation disc. The installion failed and now my mac won't start. It hangs on the apple logo screen for about 2 minutes then dies. I've tried booting from the disc and using the repair disk utility but I get an error saying the disk can't be repaired and instructing me to back up my files and erase the disk. Problem is, I can't get to my files because all I can do is boot from the disc drive. Can anyone suggest a way get the installion to work, or a way to back up my files?
iMac is 3 years old, 4 Gb ram and 2.66 Gh processor
Any help would be much appreciated.

Possibly we can save some of the files.
When booted from the Install Disc...
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
Hopefully you have another external drive and can Image the whole internal drive to an external.

Mac won't start up and shows grey screen
