iMac to start speaker crackles
Hello
I have an imac 21.5 "mid 2011 with OS 10.11.3
is a few months to start the iMac, the speakers make a Crackle noise. It seems like an electrical interference independent of the volume of the speaker.
I'd like to understand what depends on it and how to fix it.
Thank you
Gianluca
Hello Karnhack,
Thank you for using communities Support from Apple!
I understand that you hear crackling sounds like possible interferences during start up your Mac. Did you just hear that noise at startup?
It is possible that this could be a sort of interference, but I would say that resetting the NVRAM on your Mac as a troubleshooting step.

See you soon!

My iMac, with 1 disk of merger to, was very quick to open the OS since multinational April 2015, then suddenly became very very slow to open recently. For example the Apple logo appears in a few seconds and the load in a few seconds more. Now the Apple logo minutes to load.
Latest version of the OS is 10.10.5. It's 3.1 GHz Intel Core I7 processor. The memory is 16 GB 1600 MHz DDR3.
No idea why the slow start happening? Any suggestion would be appreciated.

Does anyone else have an iMac that starts typing on its own?
I try to type a password and the computer just starts typing, indefinitely. I'll write an email and the computer hits back again and again and again. Then it starts to beep me - the beep that says: "has already hit this key! I have no control over what he types. My only recourse is to restart, which works most of the time. Until yesterday.
This goes on 5 months patiently trying a bunch of solutions, none worked. Of course, it produced intermittently, making it much more difficult. However I called and talked to a counselor while he was hoping it would help. Nope.
I went through 5-6 people from Apple for probably 7 + hours on the phone. Finally, they said make a genius bar appt and bring it in. Yes, I did. The whole darn 27 "thing. They gave me a new keyboard to try. Nope. They suggested I have reinstall the latest system. Yes, I did. Nope.
I'm getting pretty well supplied upward.
I will say, in all the conversations I've had, I'm pinned a rude woman. Each representative was pleasant and everyone has, according to me, tried very hard to make it work.
Unfortunately the last woman I spoke with, a Counsellor who gave me his phone number and extension, did not return either my emails, nor my phone messages.
So I'm screwed out of. When he arrives, of course, I can't use my machine $2000 +. Fortunately, I have a laptop or I would scream bloody murder. Maybe I need to start screaming bloody murder. I want that they fix it or give me a new. 5 months is enough.
Someone else has a computer that writes on its own? Of course, I'd advice anyone can offer.
I've had this happen a couple of weeks - except that it was on my end 2012, Mac Mini, on which I had just done a clean install of El Capitan. The Mac Mini was using the Apple bluetooth - like the iMac keyboard.
I've only had the question on the login screen - it would just start repeatedly typing in the password field. To solve - and to see if was indeed a problem with the keyboard - I went to a wired keyboard - and the problem stopped. This little told me it was the keyboard. To troubleshoot further - I happened to have a spare identical keyboard - so I have the bluetooth of the iMac keyboard odd and not matched the keyboard problem of the Mac Mini. I paired the keyboard blue tooth with the Mac Mini iMac and paired the bluetooth problem with the iMac keyboard. I did a reset SMC, PRAM/NVRAM reset and start secure on the iMac and Mac Mini (precaution). The problem never happened again. I was not yet the keyboards of return - and it has been a few weeks. If you do not have a wired keyboard or bluetooth spare parts - you could try the following:
1 turn off your iMac keyboard pairing.
2. join your iMac keyboard
3 stop the iMac
4 perform a SMC reset (iMac, you delete all the devices to the iMac - unplug the power cord at the back of the iMac.) Wait at least 15 seconds. Reattach the power cord to the iMac. Wait at least 5 seconds. Press the button.
5. when the iMac restarts - stop it again.
6 reset the PRAM (memory NVRAM) - by simultaneously pressing the keys CMD OPTION P and R, after hearing the boot chime. Keep hold the keys until you hear the chime again. Then keep hold the keys down until you hear one more chime. Release the keys - let the iMac start.
7 judgment of the iMac, once again.
8. perform a startup by holding down the left SHIFT key when you hear the boot chime. Now keep the left SHIFT key until you see the progress during the start bar. On the login screen - it should be a message from Red starting at the top right of the screen. Allow the iMac to sit at the display of connection for 5 minutes. Connect to iMac - (it will be slower than normal). Allow the iMac to sit to the desktop for about 5 minutes - do not run all the apps. After 5 minutes - stop the iMac.
9 start the iMac and Note If the keyboard is no longer slap on its own.

iMac slow start caused by the spotlight?
For some reason, my iMac i5 2013 end has always been slow to start (at least as long as I can remember). its quick access through the actual boot process but, once I connect to my profile, there are about 5-7 minutes to load and become usable.
- I tried to make another profile and started in to confirm that it was my profile. It is exclusive to my profile. very good start.
- I reformatted my mac and reinstalled OS X and recreated my profile. Problem comes back in a month or two.
- Took a look in the system log and found that his 'looks like' spotlight is very slow on this topic for some reason any. I turn off the projector and the question is basically gone! This feels like dressing difficulty however, no idea what continues?
Here is the log from BEFORE I turned off the projector: it won't let me post the log because of his characters... but here is a screenshot of the suspicious party...

Equium L10-273: speaker crackling
Hello
one of the speakers on my laptop doesn't work very well anymore. When its at full volume, it makes a horrible crackling noise and distorts everything. Im having to use the other speaker.
It can be replaced?Thank you. Jennifer
Hi Jennifer
If some of the material is defective, it can be replaced. I put t know which model of laptop, you have exactly, but the fact is that the sound quality on all models of laptops is certainly not the same. On some laptops small budget speakers are not one that suits and the sound quality is also very good. You can see especially if you set the volume to the maximum level.
Now the question: which model of laptop you have exactly?

New 1 day old phone and the speaker is crackling during the speakerphone mode or when you adjust the volume level of notification. In addition the audio level of voice calls is barely audible. It's exactly like my old Z10. Come on blackberry? !!! You guys are really all QA before packinging your products or is - this new Bond is a repackaging of exccess and components of the Z10? It's my 3rd 10 blackberry device. I'm running out of excuses to continue to support the guy.
I returned my jump today and bought another classic. In addition to the problems I mentioned, I also found this mixture will connect to jump at all. With this new specific classic speaker working, no sound of cracklng. Everthing works. 10.3.1.1865 firmware version

Speaker crackling sound with media player on satellite
I have a problem with my speakers, everytime I go to use media player, all I hear is a crackling sound to them, any ideas.
Hello
What is the crackling appear since the first day?
It happens if you play the CD or watch movies?
Maybe some codex are missing.Have you tried to update the audio driver? If this isn't the case, in order to check it out.
However, I also read that sometimes, a new installation of the OS could solve these problems.
I don't know why, but maybe some files on the HARD disk may be damage. -

When I turn on my machine, I have a small circle in the middle with a picture on and my wife below name.
My wife passed away on January 8 this year and I have managed to change his pic, but I would like to change the name under my own name
How it's done anyone?
The easiest way is to turn off FileVault in the Security & privacy preferences window, wait for it to finish the decryption (usually a few hours), then turn it back on if you wish. Back up all the data first.

I want my music back. Most of it I ripped from my CD collection, lots of it, I downloaded P2P, and the rest came from the iTunes store. What is happening with this?
Can anyone help?
Thank you
If you would allow him to synchronize, you would have a backup on your computer.
Everything you bought from iTunes can be downloaded again free of charge. (Good luck to remember all the titles of the songs.) The CD RIP are probably history.

Sound crackling of the new Satellite L500-1XC right speaker
Hello
I bought a new Toshiba laptop yesterday and started from today afternoon, but since then, I have my speaker crackling noise right I want to know if there is any problem or it s due to moisture.
It is not easy to say what the problem is here, but if you have this crackling definitely maybe is there a serious problem with the speaker.
Try to contact your dealer as soon as possible and ask for replacement. In my opinion, he should take the computer laptop back and give you new product. -
Acer Aspire E11 constant crackling sound
Today, I got my laptop, and as soon as I started, there was this crackling noise (which is really annoying). It sounds like the speaker crackling, but it is still there after I cut the laptop. I don't know if this is normal or not, it would be nice if she could go far.
Thought it would be a laptop quiet nice, given one of its selling points was no fan.
This is what it sounds like this? (increase volume)
