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..

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

Why did I lose my apps on my iPhone after I update to IOS 6?

Why did I lose my apps on my iPhone after I update to IOS 6?

I would guess that it is because you failed to make sure that they were all on your computer before you updated.

I have an iphone 4. I recently updated to IOS 7. Now when I am talking on a call, the mute or speaker button will activate. Very frustrating...help. How do I turn it off?

My iPhone 4 has the same problem. Other people I know have similar issues. Other threads in the forum have commented that there could be a problem with the screen proximity sensor that is triggered by your ear being near or touching the on-screen mute or speaker button. They claim that an external case or a screen protector could cause the proximity sensor to malfunction, or possibly the screen needs to be cleaned. I tried putting a non-conductive thin cover over the phone, and it did not help. In my opinion, the phone works as designed. Other than switching to another brand phone or Apple fixing it with a functional iOS update versus a pretty iOS update, I've only found one solution, which is to use a headphone/microphone or a hands-free device. Of course, using a headphone/microphone is often inconvenient.

It says I can drag Pages documents from iMac to iCloud. But nothing shows up. Using latest with all turned on. How do I get Pages up to iCloud? The little wheel like action menu does not appear.

Why is it asking for my billing info but the app is free how do I turn this off?

Why is it asking for my billing info but the app is free how do I turn this off?

possibly to verify age or perhaps the app has "add on" features that cost and they would need to know where to bill these to if you wanted them
I know you can store your billing details, even a credit card number, securely within your iTunes account to prevent you from getting this prompt for future apps

Runninig 10.6.8 on new iMac. The last wo weeks I keep loosing internet and have to turn airport off and on to restore service. It is not the router as my two laptops do not have this problem. I read that in 2008 MMP's had a similar issue.Any thoughts?

Go to /Library/Preferences/System Configuration
Move all the files from the System Configuration folder to the Trash.
Restart your Mac. See if that made a difference.

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.

24" iMac - fan comes on, Mac won't sleep

Sometimes when I try to "sleep" my Mac, the fan comes on, the screen blanks, and then immediately it comes to life. Other times the fan comes on, even though I don't think it's overheating, and then maybe I can sleep it, and maybe I can't.
Anyone else seen this problem? It's not the end of the world, but it's pretty annoying!!

I spent 25 minutes on the phone with AppleCare and we did a lot of things like resetting the PMU, the PRAM, reparing the hard drive, trying to do the same with another user account. It turns out it's a hardware problem and I need to send the computer to a service center...
Basically: no solution we can find on our own.
My iMac is 20 days old so that makes me quite unhappy...

Why did my isight camera come on by itself

My isight camera came on by itself. I admit that skype was running, but I was not talking to anyone.
The next day the isight cameara came on for less than a second and went off.
Why would this happen?

ArisB wrote: ... Why would this happen?
Because either:
(1) you (or someone else) have added software that turns the camera on and off automatically, or
(2) something is wrong with your Mac's hardware or software.
If you did not do the first and have given others access to your Mac, you can eliminate (1).
Here is how I would work the second possibility: Uninstall (follow Skype's uninstall instructions) Skype. Then restart Mac, use Disk Utility to repair permissions, and then test your camera again. Follow the suggestions inApple's http://support.apple.com/kb/HT2090 article.
If the camera works correctly now, reinstall the latest Skype that is compatible with your Mac. If the problem returns when you install Skype and goes away whenever you uninstall it, Skype must be causing a conflict that results in your camera's unexpected behavior. Search or post in Skype's dedicated support pages for help for this Skype-specific problem.
If the problem continues even when Skype is properly uninstalled, post back with as much info as you can provide on the latest behavior. Confirm that you have used the proper SMC/PMU reset from the Troubleshooting article, and tell us which (if any) apps and user accounts work properly and which do not. We will offer more specific suggestions based on the details in your reply.

If your machine was made after 2009 you probably installed th wrong HD. Beginning in 2009 Apple began using HD's that had an integrated fan sensor. If you did not use one of these drives then that is the problem. You should contact OWC (www.macsales.com) or visit your local AASP and they will help you select the correct HD to use.

Why did all of my dashes "-" change to "&ndash" after my client made in browser edits and I accepted

I created a site in Muse. Published out to Business Catalyst and all was good. My client made several hundered edits from the Biz Cat dashboard. They then asked me to make some more substantial edits to the design so when I opened Muse, I accepted the edits they had made. On each page there is a column for Customer quotes. Each quote is signed of with a name.... such as "- Judy Miller." I noticed, after accepting the inbrowser eidts that all dahses before the names now had "&ndash Judy Miller." I tested in preview and sure enough, it was there still. So I then did a preview in browser forcing the page to load through the server and unfortunately the &ndash was still in front of the name. So I opened my browser and pulled up the site to make sure it still had the correct dash and it did as I had not published from Muse since accepting the inbrowser edits.
Why did that happen?
How can I prevent it from happening in the future?
Right now I am stuck in limbo as I can not publish out in fear of populating the site with dash replacements. I can go in and change everyone and then make the changes I was supoosed to make for the client but who is to say it won't happen again and again?
Thanks for any info you can shed on this. I have been on chat support for over an hour now and still have not gotten a hold of a support agent at Adobe. That clearly sucks and they should employ more people to handle the problems when they occur.
Wes

Hi Wes,
You've encountered a bug that has been reported by at least one other user, but one that we haven't been able to reproduce internally. To help us investigate this, could you determine which browser/platform (inlcuding versions) you client had used to make the edits?
Also, if you could send your Muse file to [email protected] (with a link to this forum post), I can look at fixing it, reverting all "&ndash" instances to "–". Sorry for the inconvenience.
Thanks,
Abhishek

Why did some applications have to rebuild their database after a Time Machine rollback?

Recently my system (10.8) got totally borked, so I booted into recovery mode and rewrote the entire disk from a two day old Time Machine backup. When I started back up, I found that:
Spotlight needed to reindex the entire disk.
Dropbox didn't recognize my computer, and after I logged back in it re-downloaded everything in my dropbox folder (even files that hadn't changed in the last two days).
Microsoft Office needed to rebuild the user database before I could use Outlook.
If my system was restored to the exact state it was in two days ago, why did all this happen? What made these applications behave differently from how they would have if I'd just left the computer off for two days?
I'd also be interested if anyone could point me to a list of things that are lost, reset, or rebuilt after restoring from Time Machine. Many thanks.

If this is on your Apple Mac, you might like to ask in an Apple forum ??

Why did I lose all my Verizon ring tones after updating to new software?

Why did. I lose all my Verizon ring tones after updating to new software? Always worked before, now they are gone! Contacted Verizon, who could not explain.

I was having a similar problem and here's what solved it for me: Under Settings>Notes the default account was changed from iCloud to another account for no apparent reason when I upgraded to iOS 7. When I changed it back to iCloud, my notes started appearing on all devices again. You might also want to check the Accounts setting under the Notes app to make sure All Notes is checked to retreive notes from all accounts. Similarly, Settings>Mail,Contacts,Calendars has a default account that should match as well. Good luck.

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?

Please read the warranty paperwork that came w/your computer.
You have 14 days to return the computer w/no questions asked.
You have 90 days of FREE phone tech support on top of your standard 1 year warranty unless you also purchased AppleCare which gives you an additional 2 years of coverage plus FREE phone support.
Strongly suggest that you take FULL advantage of the above before it runs out. Let Apple deal w/the problems.
If you DIY and mess up, your warranty will be VOIDED!
