(fans?) randomly get very noisy - not sure why
Hi,
A few days ago my mac pro started randomly getting very noisy from time to time. it sounds like it rev's up to medium-high speed; not the full blast it can do but enough where it is annoying and clearly not normal. It happens every 10 to 20 minutes, goes on for a few, and then quiets down again. I can only assume it is a fan making the noise but dont know for sure.
I really don't know what could be causing it because not only has it not happened before until a week ago but I am not running any intensive apps at all yet it still happens.
I'm not really sure if anyone can help, but would appreciate it if anyone had suggestions on any tests i can run to check if something is wrong or if there is anything I can do about it.
Thanks
The first thing I would do is open the case and blow out all the dust. If there is a lot of buildup, esp on the heatsink ribbing on the procs and video card, it could easily cause your increased fan activity.

I received a text today while at work about iCloud keychain verification code. I have not signed up for it or anything that uses it. I work out of the city with limited internet access so not sure why I would be getting this. I only got this number about a month ago. Apparently someone else had the number before because I get texts from his family members wondering whats going on. I got one yesterday and the person didn't seem to thrilled that the number was cutoff and today I got 2 texts about iCloud Keychain which I don't even know what it is. Seems suspicious to me. If the person who use to own the number is doing it he should know it is not his number anymore because he obviously didn't pay his bills. I'm not too sure about iCloud Keychain so just want to know my info safe?? It says it can store credit card numbers which is what gets me worried. Frankly I think it's pretty stupid to save that kind if information with any kind of app. But I don't want some random person trying to access my personal information because they are bitter they lost their number. Please let me know as soon as possible so I can change passwords or anything that is needed.
thanksIf it were me, I would go to my carrier and get a new number. Since you have only had it for a month, the inconvenience would be minimal.

Photos from the Internet will not load correctly. I get white boxes with blue question marks inside. This has only been happening for the past 3 weeks so I'm not sure why it is happening.
Yes - email & text work fine but when I use something like Google Images or search a blog with imbedded photos I get the empty white boxes with question marks. If I click the question mark it opens the photo but I can't possibly do that for EVERY image on EVERY page I search!?!?! I've rebooted the iPad & my wireless card several times but neither action helped. Have any clue what I should do now?

My iphone5 crashed Wed May 29 and I am not sure why.. I had to do a restore and have been trying to slowly get everything back on the phone... Yesterday June 6 it blacked out once and I don't have everything on the phone as before.... Is it damaged and should I try to get a new one?
Thank you again for all of your help!! I really appreciate it!
I think I am following -- I was able to upload to my iPhoto and all photos and videos are there that is a plus! I tried to create an Event in my iPhoto and put all of my photos in that event but for some reason, now my iTunes it not recognizing that Event in my iPhoto. It is not allowing me to import just that event at the moment but I may be doing something wrong. At least all of my pics and vids are in iPhoto so that is a plus and I know they are at least saved somewhere. Just for some reason, my iTunes it not locating the event that I created with only those photos.
Thank you for letting me know about my contacts! How do I know if I have the contacts app?
Also, I had no clue that my iCloud could be backed up via cellular data! However, is this a new feature with the most updated iOS?? Unforutnatly I am like 2 iOS updates behind because I don't have enough storage on my phone. I still get the notification that my phone needs to be plugged in and connected to wifi in order to back up to the cloud :-(
How can I sync using USB? Right now when i click on the info tab for my iPhone in my iTunes this is the answer that I get -- I am a little unclear as to what it means.

I am not able to convert movies, keep getting this message The document “The Walking Dead Trailer - YouTube-2.mp4” could not be opened. The movie's file format isn't recognized. not sure why, anybody know
Sounds like someone ripped the movie off of YouTube and it got corrupted in the process. Try getting the movie file again, or try using an alternative movie player such as VLC: http://www.videolan.org

Have you tried resetting your PRAM?
Shut the Mac down.
Holding the Cmd+Opt+P+R keys, press the power button.
Listen for the "startup chime" to sound three times and release the keys.
It should run better after it finishes booting up. -
also say explorer not reading SWF files and I have to reload them? Not sure what that is either,
Thanks

I am walking through Apples tutorial getting started with iOS development. I am at the storyboard area and can't seem to drag the cancel button to the green exit. I am not sure why the exit button doesn't except it. Is anyone else having this issue? Is there a work around? I have done this app twice and still cant get the exit to except the Cancel or Done bar buttons
Yes I checked it. As far as I can see I did everything Apple said to do. I took some screen shot so you can see how the screens are connected and what and where the code is, and what it does when I drag the cancel and done bar buttons to the exit

Audio in iMovie files is now Gone :-(!! Not sure why?
I have been using iMovie for a few years and love it. Recently none of my video files have any audio. Not sure why and if I did something wrong.
in Final Cut Pro X (I hate it!) the video is fine, also fine in Quicktime.
Anyone have any suggestions as to what I may have done wrong or any suggestions?Thx Much AppleMan,
I appreciate the quick help.
Nothing has changed since I started using iMovie '09 2-3 years ago. Something is very wrong. All the videos in my iMovie had audio, now many do not.
I have a hunch I have clicked something I should not of....
Wish someone could help with why I no longer get audio when importing to iMovie, when all worked perfectly in the past. -
Can't get ACD working not sure what's wrong
First off can users with SNR or shared extensions work with ACD? I'm following the guide but can't get anything to work.
I made a basic ACD called 515 as the pilot number with all basic settings and put 2 of my extensions as members. I then put on my autoattendant that pressing 1 goes to the ACD.
If I call the auto attendant and press 1, it says connected, then just hangs up.
I also don't know how to tell if I'm logged in to the ACD or how to log out. It says in the help that you use the HLog key to log in and out, and I do have that key on my 7970 and 7960 but its grayed out on the 7970 and on both phones just says That key is not active here. So not sure what's wrong, it seems like it's just not working in general based on it just hanging up when the AA transfers a call to it. If I try to dial the pilot number I get a busy signal but I think it has to come from the AA from what the guide said.
Not sure what's going on or how to troubleshoot this, any suggestions?Okay good to know because the help pages on setting up hunt groups say the extensions can't be shared ones so thought maybe that's why. It seems to be something though because I made a new normal extension, removed the shared ones from the ACD members list and added just the normal one. Now when I press HLog on the phone it logs in and out it says.
However calling the ACD does the same thing, just hangs up.
Is Shared extension not what I'm supposed to use if I want to have say extension 300 show on a physical phone and IP communicator? Since normal only lets you add it to one device, I assume share is the right option? Just seems like it causes issues with ACD.
Not sure how to run that command you said above, I'm just following the built in help which seems straightforward just not sure why it won't work. -

Hello, What does Kruler Klash mean? Not sure why an error in posting occured.
I ended up figuring out a solution, but I'll get to that in a sec.
To answer your question, I converted the .wmv file in a program called Media Converter (available in the App store), and converted it to an h.264 file (then later to a .mov file, and then to an .mpg). I could view the file, and work with it in projects, but any project I tried to output with any version of said file, would result in the afor mentioned message, with the same results in FCPX (and Compressor 4 as well). I tried multiple frame rates, resolutions, files types, re-converting the file, all with no luck. My impression from said experiments, and reading other discussions was that it was a corrupt file.
Then I got frisky...and a little desperate. I brought the converted file (the .wmv to .mov) into Motion 4... and an export worked first try. So I exported a pro-res file from Motion 4, and used that file in the already built Motion 5 project, and voila!
So, who knows what that means in real terms, as for the whats and whys. -
