• iMac froze on Start up on the Apple logo and the spinning wheel.

  Hello

  Can someone please help. My iMac started freezing when I clicked on any application or attempted to open anything. I turned it off the power and then turn it back on. Now I just get the apple logo with the spinning wheel down on white background. I tried to close again and reboot hold command + s, Ctrl + r, Ctrl + p + r, but nothing can get past the logo and the spinning wheel. I'm running snow leopard top and it worked fine until a couple of days. I can't on the utility disk or anythong at all. I'm not the most intelligent in the computers and it has me really stumped. Any kind soul can help with some info?

  KND regards,

  Before doing all this, what is your status of backup? You have Time Machine or a clone of your hard drive? If this isn't the case, it may be best to do nothing until you are able to see if you can find a way to save your data if things go from bad to worse.

  That said, assuming you are running OSX 10.5.8 (like on your profile) or Snow Leopard (according to the guidelines of this forum), have you tried starting restoring 1 gray disc that came with the Mac or the Snow Leopard installation disc? Insert the startup disk by holding down the c"" key. You may need to push the disc for the CD/DVD drive so that it can swallow the disk when you start if you can't get the Mac to accept the drive in its current state.

  If all goes well it will boot from the gray disk, although slowly. Once started go to the Menu utilities > disk utility. Launch disk utility, select Macintosh HD and click on "repair disk". If changes are made click on repair disk again and repeat until you get a clean pass. Once that is done, try to restart normally in the Apple menu.

• iMac 8.1 stuck on the apple logo

  Model: iMac8, 1

  2.66 GHz Intel Core 2 Duo

  At 2BG memory when the problem started

  Mountain Lion 10.8.5

  Is in trouble with occasional frosts. Would be closed and it should restart very well. About 2 weeks ago, the computer froze. I shut down the computer and restarted. The apple logo came with the spinning wheel, and then just the apple logo.

  I can start safe mode. Tried resetting the PRAM, reset of SCM. Tried to start with all peripherals except keyboard and mouse disconnected. Use the command R to start the computer and went into the disc utilities. Disc checked and it said disc looks OK. Verified permissions. Mistakes came for iTunes more a warning which was not repairable. Fixed permissions. None of these permits to start properly.

  Parle talked anyone computer repair who suggested to unplug the computer, hold the power button while up to one minute, plug the computer back in and pressing the Start button. It came in fine. A few days letter that the computer froze and I had to stop it. You press the Start button, got the spinning wheel, so only the apple logo and apple logo. Start the computer by pressing command + R and reinstalled Mountain Lion. Installation once it stuck at the apple logo again. Active disk. Drive seems to be OK. Permission verified. Permission with iTunes but issues no warning this time. Repaired permissions. Nada.

  Inserted the installation disk, turned on the computer while holding D key. A ran Apple Hardware tools (tests of short or long). This error message came up twice with different numbers of rpm: 4MOT/1/40000003: drive HARD-110. I know that it's the hard drive fan. Computer repair man came out. Thought problem may be because I only had 2 GB of memory and ran only to open the Lion of mountain with several programs. Upgrade to 4 GB memory, which is recognized by the computer. But the computer still does not start correctly. Tried the Single Mode and run/sbin/fsck - fy. Said it seemed OK, but changed the volume. Ran he says once again and everything seemed OK. Still will not start.

  When I start in the disc, part of the grey background Utilities is missing. If you move the cursor on the screen, the gray background fills.

  Also, when I try from normally I get startup chime, the apple logo and the spinning wheel. After that make a spin the wheel stops, there is sort of a Flash, then the wheel goes and remains the apple logo. I can hear the computer tries to do something, then the arrow cursor appears and can be moved around the screen. It's like that.

  Also installed Mountain Lion on a USB key, it made the startup disk and tried to start the computer normally. Still will not start.

  Any ideas or suggestions for what could be wrong or other things to try?

  1. the present proceedings is a diagnostic test. It doesn't change anything for the better or worse and therefore, by itself, will not solve the problem. But with the help of the results of the tests, the solution may take a few minutes, instead of hours or days.

  The test works on OS X 10.8 ("Mountain Lion") and later versions. I do not recommend running it on older versions of Mac OS X. It will do no harm, but it will not do not much good.

  Do not be put off by the complexity of these instructions. The process is much less complicated than the description. You make the tasks more complicated with the computer all the time.

  2. If you do not already have a current backup, please back up all the data before doing anything else. The backup is needed on the general principle, not because of what anyone in the test procedure. Backup is always a must, and when you encounter any kind of problems with the computer, you can be more than the usual loss of data, if you follow these instructions or risk not.

  There are ways to back up a computer that is not fully functional. Ask if you need advice.

  3 here is instructions to run a UNIX shell script, a type of program. As I wrote above, it doesn't change anything. It does not send or receive data over the network. There is no to generate a report on the State of the computer human readable. This report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents for me or someone else.

  You should ask yourself if you can believe me, and if it is safe to run a program at the request of a foreign national. In general, no, he's not sure, and I encourage it.

  In this case, however, there are ways for you to decide if the program is safe without having to trust me. First of all, you can read it. Unlike an application that download you and click to start, it is transparent, anyone familiar with the code can check what it does.

  You may not be able to understand the script yourself. But variations of it have been posted on this site several times over a period of years. One of the million registered users to have read the script and set off the alarm if it was dangerous. Then I wouldn't be here now, and you would not be reading this message. See, e.g., this discussion.

  However, if you cannot satisfy yourself that these instructions are safe, do not follow them. Ask other solutions.

  4. here is a general summary of what you need to do, if you decide to go forward:

  ☞ Copy text from a particular web page (not this one) to the Clipboard.

  ☞ Paste into the window to another application.

  ☞ Wait for the test to run. It usually takes a few minutes.

  ☞ Stick the results, which will be copied automatically, in a response on this page.

  These are not specific instructions; just a glimpse. The details are in parts 7 and 8 of this comment. The sequence is: copy, paste, wait and paste it again. You don't need to copy a second time.

  5. try to test in conditions that replicate the problem, to the extent possible. For example, if the computer is slow intermittently, run the test during a downturn.

  You may have started up in safe mode. If the system is now in safe mode and works pretty well in normal mode to test run, restart as usual before running it. If you can test only in safe mode, this.

  6. If you have more than one user and a user is affected by the problem, and the user is not an administrator, and then run the test twice: once under the affected user and one administrator. The results can be different. The user that is created automatically on a new computer, when you start it for the first time is an administrator. If you are unable to log in as an administrator, verify that the user concerned. More personal Mac have only one user, and in this case this section does not apply. Don't log in as root.

  7 load the linked web page (the site "Pastebin.") Press the combination of keys command + A to select all the text, then copy it to the Clipboard by pressing command-C.

  8. start the Terminal application integrated in one of the following ways:

  ☞ Enter the first letters of his name ("Terminal") in a Spotlight search. Select from the results (it should be at the top).

  ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

  ☞ Open LaunchPad and start typing the name.

  Click anywhere in the Terminal window to activate it. Paste from the Clipboard into the window by pressing Command + V, then press return. The text that you pasted should disappear immediately.

  9. If you logged in as an administrator, you will be prompted for your login password. Nothing displayed when you type. You won't see the usual points instead of the characters typed. Make sure that caps lock is turned off. Type carefully, and then press return. You can get a warning to be careful. If you make three unsuccessful attempts to enter the password, the test is still running, but it will produce less information. If you do not know the password, or if you prefer not to enter, just press back three times at the password prompt. Yet once again, the script will run.

  If the test takes much longer that usual to run because the computer is very slow, you can be prompted for your password a second time. The permission you grant by entering it will expire automatically after five minutes.

  If you are not logged as an administrator, you will be prompted for a password. The test will run. It just will not do anything that requires administrator privileges.

  10. the test may take a few minutes to run, depending on the number of files you have and the speed of the computer. A computer that is abnormally slow may take more time to run the test. During execution, a series of lines is displayed in the Terminal window like this:

      Test started

          Part 1 of 4 done at: … sec        …        Part 4 of 4 done at: … sec

      The test results are on the Clipboard.

      Please close this window.

  The intervals between the parties will not be exactly the same, but they give an approximate indication of progress.

  Wait for the final message "Please close this window" appear - again, usually within a few minutes. If you don't see this message in about 30 minutes, the test probably won't be completed within a reasonable time. In this case, press the Ctrl + C key combination or the point command to stop it. Then go to the next step. You will have incomplete results, but still something.

  In order to get results, the test should be allowed to perform or be stopped manually as shown above. If you close the window of the Terminal, while the test is still running, the partial results will not be saved.

  11. when the test is completed, or if you manually stopped, leaving the Terminal. The results have been saved to the Clipboard automatically. They do not appear in the Terminal window. Please do not copy from there. All you have to do is start a response to this comment and then paste it again by pressing Command-V.

  At the top of the results, there will be a line that begins with the words «Start time.» If you do not see that, but rather to see a mass of gibberish, you wait for the message "close this window". Please wait and try again.

  If personal information, such as your name or e-mail address, appear in the results, make anonymous before posting. Usually it will be not necessary.

  12. in the validation of the results, you see an error message on the web page: "you have included content in your post that is not allowed", or "the message contains invalid characters." It's a bug in the software which manages this website. Thanks for posting the results of the tests on Pastebin, then post here a link to the page you created.

  If you have an account on Pastebin, please do not select private in exposure menu to paste on the page, because no one else that you will be able to see it.

  13. When you are finished with the test, it is gone. There is nothing to uninstall or clean.

  14. This is a public forum and others can give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but all that you can not be. For others who choose to run it, I do not recommend that you view the results of test on this Web site unless I ask.

  15. the related UNIX shell script is a notice of copyright. ASC readers can copy for their personal use. The whole nor any part can be redistributed.

• I just ran the last update for my iPad and now it just continuously reboots to the black screen with the Apple Logo. Hard restarting does not help, neither do not connect the camera to MacBookPro. Any ideas?

  I just ran the last update for my iPad and now it just continuously reboots to the black screen with the Apple Logo. I left plugged in all night and still no change. Hard restarting does not help, neither do not connect the unit to aMacBookPro. When I do this, iTunes complains that it can not connect because the iPad 'expires '. Now it is disconnected, but I can't turn it off. Even close the lid will not extinguish it. Any ideas?

  Try the following. It seems yo may have to let the battery drain is completely:

  - iOS: do not respond or does not light

  -Also try DFU mode recovery mode post-test

  How to put iPod touch / iPhone in DFU "Karthik doodles."

  -If failed and that you cannot completely turn completely the iOS device, leave the battery to drain completely. After loading a hour repeat the foregoing.

  -Try a different cable

  -Try on another computer

  S ' there is still not successful that usually indicates a hardware problem and an appointment at an Apple store Genius Bar is in order.

• iPhone ran out of battery, now wont start black screen after the apple logo

• I put my date of 01/01/1970 and my iPod 6th Gen has not worked since. I tried to put it in DFU mode and it has reset, but remains on the apple logo.

  I put my date of January 1, 1970 and as soon as I rebooted my iPod (6th generation) he never returned to my home screen, but instead, he stayed on the apple logo. I tried to drain the battery, but he always did. I even connected it to my computer and put it in DFU mode to reset, but it froze at a very small percentage of loading and no progress has been made.

  Given that the DFU mode does not work, then

• by clicking on the apple logo, menus and check boxes do not work on the first click

  Strange behavior from El Capitan OS X 10.11.1.

  When I click on the Apple Logo, menus, and check boxes, the action does not stick.

  To open the Apple Logo, the menu appears quickly but then folds upwards, as if I had not clicked.  Pretty well, click on the third, the menu opens.

  In the Finder, when I click on a menu like file, edit, or display, the menu appears, and then restores upward. Again, after three clicks in opens.

  In Safari, on a page Web, clicking on a checkbox does not stick. I need to click three times.  I when in Safari settings to clear the cache, I also checked the box to request the site "don't follow me." And even in the actual application of Safari, the box wouldn't fit.  I clicked it three times before the box stuck.

  Installation program:

  iMac 24 - early 2008

  4 GB

  El Capitan 10.11.1

  I changed the mouse, and this has solved the problem.
