any fix for iMac not loading....have tried reboot and cleaned discs...all ok but have to reload osx to start iMac up everytime..
iMac
Can you be more explicit about what you have done? Then please explain exactly what happens when you startup.
hi Kappy...well have looked at thread/answers relating to osx problem loading at 50 percent then just stops...advised power off disconnet wifi and power on control space bar R then options to cleand hard disc reload osx etc have done this but still have problems restarting..
OK, if I got it all, you have erased the startup volume and reinstalled OS X, but what happens at startup? Does it restart immediately and produce a black screen with white type message lines? Does it always get to the Apple logo with the progress bar, but never finishes? When you did the clean erase and install of OS X, did it exhibit the same problem from the very first startup or not until you restored your data?
If this is happening from the very beginning of your reinstallation, then my guess is you have a failing disk. I would then consider making an appointment at the Apple Retail Store - Genius Bar and take it in for service. If you are not in the USA or cannot set up an appointment this way, then contact your local Apple Store directly.
Hi Kappy I read that it might be failing disk,however iMac is up and running now....I have actioned repair permissions and noted that HD has 695gb left . I just know that if I power off then I will have the same scenario again. As I recall I had a black screen on startup.....Are there any actions I can take whilst its behaving now...? Im running 10.11.3 El Capitan.............
If you have good backups, then you might try erasing the drive and reinstalling the OS X version that came with the computer pre-installed when new. This may involve using installation DVDs that came with the computer. If the computer came originally with Lion or later pre-installed, then you would do this:
Install OS X Using Network Recovery
Be sure you have backed up your files because the following procedure will remove everything from the hard drive.
Boot to the Network Recovery Server:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Reinstall OS X: Select Reinstall OS X and click on the Continue button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.
If the drive is failing (check the SMART status reported in Disk Utility or with a third-party utility.) If that does not show the drive as "Verified," then there is a good chance it is failing. However, SMART may report a drive as verified when it is actually failing. It is not highly reliable.
The best thing to do is as suggested above - take it in for service - if you cannot get it back to normal.
