why did my iMac quit reading cd's?

Zap the PRAM and Reset the SMC, then try reading a CD/DVD again.

    why has my iMac quit showing videos?

    Thank you for the idea but I have downloaded Flash three times within the last hour and still no video.  I have tried youtube, FoxNews, and CNN news.
    Could I have some settings wrong?  If so whitch settings?

    Why did my iMac fan come on very noisy after 1 hour of use ? I had to turn it off to stop it

    Just updated details - os x 10.8.5 .....
    found an answer that could have been problem with CPU and a runaway application (possibly Bin Weevils) which my son was running at the time.  I shall check the activity monitor next time to see what percentage cpu is being used..

  • Why Did My iMac Hard Drive FAIL?

    I am majorly upset right now.
    My iMac 2009, 21.5"  (4GB Ram, 500GB Hard drive) computer that was practically unused since it was in storage for 2 years in my basement while I went out of town on business- suddenly had a Hard Drive Failure for no reason! Since the Warranty was expired on Apple Care, I took it in a Mac store - only to be told by the repair man that the hard drive needed a replacement. He did quick testing, and these were the results:
    Ran MRI and everything passed
    Reset pram and SMC
    Ran storage diagnostics
    Proposed Resolution: Replace hard drive
    Total cost: A WHOPPING $229.00 plus tax for the hard drive plus labor costs. When I asked if I could just upgrade to a 1TB Hard drive since I was shelling out money anyways, Apple flat-out REFUSED- saying they couldn't put a warranty on a new hard drive, just the replaced one. Sounds like complete BS to me!
    Further more, I would like to know how the **** this happened! A few times when the iMac was on the table and running, I lifted it up and clunked it back down a bit rough to readjust it- but it continued to work for a few more days. I doubt that would ruin a hard drive. I own a Macbook 13" that I clunk around all the time, the hard drive has never failed. Suddenly my hardly-used iMac that worked out the box when I first started using it again suddenly has a random hard drive malfunction a week in??? And now I'm out $250.00. I just feel jipped. I thought Apple products are meant to last. Apparently not. The guy said "Well it's a four year-old computer". Yeah but I only used it one year and then it was in storage! So whose to say THIS hard drive won't fail as well?
    Why did this happen?

    Hard Drive Warning (all makes and models)
    Ironically but logical, new hard drives are far more fragile than one that has been working for several months or a couple years. So beware in your thinking that a new hard drive translates into “extremely reliable”!
    Hard drives suffer from high rates of what has been termed "infant mortality". Essentially this means new drives have their highest likelihood of failing in the first few months of usage. This is because of very minor manufacturing defects or HD platter balancing, or head and armature geometry being less than perfect; and this is not immediately obvious and can quickly manifest itself once the drive is put to work.
    Hard drives that survive the first few months of use without failing are likely to remain healthy for a number of years.
    Generally HD are highly prone to death or corruption for a few months, then work fine for a few years, then spike in mortality starting at 3-4 years and certainly should be considered end-of-life at 5-7+ years even if still working well. Drives written to once and stored away have the highest risk of data corruption due to not being read/written to on a regular basis. Rotate older working HD into low-risk use.
    The implication of this is that you should not trust a new hard drive completely (really never completely!) until it has been working perfectly for several months.
    Given the second law of thermodynamics, any and all current mfg. HD will, under perfect storage conditions tend themselves to depolarization and a point will be reached, even if the HD mechanism is perfect, that the ferromagnetic read/write surface of the platter inside the HD will entropy to the point of no viable return for data extraction. HD life varies, but barring mechanical failure, 3-8 years typically.
    Data redundancy (copies) makes all HD crashes inconsequential, an irrelevancy.
    There are only two kinds of hard drives, those that have failed, and those that will fail, regardless of quality of manufacture.
    Any Macbook or desktop should be idealized as a working platform computer system, containing all your applications, documents, and weekly-use necessary files; and all media files such as ‘big-data’ (music/PDF collections/video/pictures), unless directly needed in the near future, should be kept off the computer and on external storage USB or likewise bare hard drives.
    Never consider any computer a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device. Anyone who thinks data is safe on any computer, even copied upon multiple partitions is making a mistake that will, without fail, strike.
    Never backup your data exclusively upon magnetic hard drives or flash storage, nor consider same since magnetic storage degrades over time, roughly 3-8 years, even under ideal storage conditions.

  • Why does  the iMac quit after 90 minuets when listening to iTunes on Apple TV

    RSS

    I have this same issue, even after new iTunes (12.01.26) and upgrading to Yosemite – iTunes plays nicely for about an hour, then stops and the iMac reverts to the log-in page. Under Energy Saver, Computer Sleep (Never) and Display Sleep (1HR). I have changed the last setting to different times but no joy. Does anyone have a good suggestion for this anomaly?
    Found this text in the help file:
    Prevent computer from sleeping automatically when the display is off
    Select this option if you want your display to sleep and your computer to stay awake.
    HOWEVER, this option does not show up under the Energy Saver on my iMac (27in. Mid-2011)
    Anyone?

  • Why did Photoshop CS5 quit opening .pic files?

    I have Photoshop CS5 installed on an iMac 10.6.5. I opened a .pic file. A few minutes later I installed the optional plugins. I restarted Photoshop CS5 but it will no longer open .pic files. If I change the name of the file by adding a t, .pict, it opens. What happened?

    Maybe so.  But ten years ago, extensions were not critical on the Mac at all.  Even files without extension suffixes opened without further ado.
    Also, at what point did Apple stop looking at the creator of the files?  That has been another headache—which could make a difference in your case.
    Some folks come here looking for help, others come here looking to learn, yet others come here looking to argue, complain, rant or vent.
    Keep in mind that we're all users and volunteers, including top Adobe engineers like Mr. Chris Cox, who generously come here on their own time and dime to contribute, teach us and help us out.

  • Why did my iMac data usage recently increase dramatically?

    I have a Hughesnet internet data use limit of 15Gb per month which typically for my family is sufficient.  As of last Thursday April 10 around 7AM my data use shot up and continued consistently high every hour.  It started at 200 - 300 Mb / hour, jumped to ~550Mb / hour at 2AM 4/11/14, jumped again to 1 - 2 Gb / hour 7AM 4/11/14 and continued until all the data had been used ~9AM 4/12/14.  I am using the Hughesnet utility to show what was used (after the fact) and I use Activity Monitor to what real time data use.  I think it would be helpful to have  a way of graphing the data use by process realtime if that exists so I can see what exact process is causing the data use.  I do not have any virus software running.
    As of Sunday 4/13/14 having no data left I contacted Hughesnet and began to troubleshoot the problem.  I disconnected everything from the internet and shut down my wireless modem.  All that has been connected since then (today is 4/16/14) is my iMac which is directly connected to my Hughesnet modem.  I was given an additional 2Gb for troubleshooting.  I left my iMac alone for 2 days.  Very little data was used and almost no programs were running when I started using it again around 11:30AM 4/15/14. Unfortunatly, as my wife started using the iMac for a few hours that data use went up again and used up all the data.  One thing i noticed was that the data use coincided with iMail being on.
    How can i identify the problem and stop it?

  • Why did my iMac arbitrarily delete files on my hard drive?

    Sometime in the early hours of 1/17/14, my iMac deleted files arbitrarily from my hard drive, mostly some data files and files that were in my download folder. At least that is all I have found thus far. Fortunately, Time Machine backups are available to re-copy them back, and I can tell it happened after the last back-up of 1/16. What would make these files diaappear on their own? In my Data files folder, it eliminated some but not all the files (no seeming rhyme or reason). The first "bad" back-up on 1/17 (with the missing files) would have occured at night when the hard drive and monitor are asleep. I am running Mavericks 10.9.1 on new iMac

  • Why did my iMac wired keyboard keys 4, 5, 6 (number pad), +, and up-arrow, (right)shift keys suddenly stopped working?

    I have already tried restarting my computer and keys will just not work and I have seen many other people have EXACTLY same problem with EXACTLY same keys as I do, but I have found any answer.
    Currently I have Mac OS X 10.8.5

    You have noticed they are all in a row.   This normally happens where a spillage has taken place.   Has the keyboard had liquid contact?

  • Why did Apple raise its prices overnight by $200 on the iMac, including refurbished models.

    Other than greed and trying to narrow the spread between the price of the old iMacs and the just-announced new iMac, why did Apple raise its prices overnight by $200 on the iMac, including refurbished models? Their existing product component costs didn't increase overnight.

    I was "literal" because I quoted the ToU. Did you read the ToU you agreed to when you established an account? Available here:

  • Why must I force quit (double press home and slide off) Mail on both my iPad and iPhone in order to have Mail access on my iMac on the same wifi network. Fetch is set to manual and my ISP is Charter.

    Why must I force quit (double press home and slide off) Mail on both my iPad and iPhone in order to have Mail access on my iMac on the same wifi network. Fetch is set to manual and my ISP is Charter.

    I don't know about the "3" but it's a POP account. I've always suspected that Charter isn't letting go using their mobile apps for iOS. Puzzling that it doesn't block the other way. That is if Mail is open on the iMac it doesn't block access to Mail on either the iPad or iPhone. I'm guessing it's their mobile apps that are the problem but they won't admit it to me.
