Hi, clara_from_brazi.
Thank you for visiting Apple Support Communities.
Here are some troubleshooting steps that I would recommend when experiencing this issue. Also, test connecting the external storage device to the computer with another cable as this can be the issue.

Everytime i try and send a message to my boyfriend through imessage on my ipad, it says "Message send failure" but all of the messages are coming in through my email, i hate texting my boyfriend through my email. So can someone help me, please.
"iMessage allows users to send texts, photos, videos, contact information, and group messages over Wi-Fi or 3G to other iOS 5 users, thus providing an alternative to standard SMS messaging for all users with devices running iOS 5."
This is what it is and what it does. You both have to have iOS 5 installed on your supported device. If that's not what your setup is, then that's your answer. -
I have been hearing about the "heartbleed vulnerability" and told to change all my passwords. Does this apply to Macs? I thought they could not get viruses and this was one of the reasons I got one.

Hi, i have a canon 60d and i have been importing videos from it onto my mac for months but suddenly when i go on image capture or iphoto it no longer allows me to import them help!!!
Have you launched and tired Image Capture? When it's launched with the iPad connected the photos will display in the window. Select those you want to upload and use the Import to: menu and select Other. Navigate to the Desktop and select the folder you created to hold those photos.

I am unable to update my apps... in my purchases page it appears as "update", then a message tells me to log on with the Apple ID I purchased the app with... Well I have tried my two different accounts and neither one will work, can someone help ??
And is there any way to sync all my purchases and accounts to just have one... It is a bit stupid that you dont even get a list of something of what account you may of used, or some kind of hint, so you could log on to the right account. I am really stuck ...
Please Advise......You can't merge accounts. But you can check your purchase history:

I have an Iphone 5S and used to sync it to my computer in the past without any problem, but now I can't, and appears the message "usb device not recognized", and the cable is good and so the USB port. Do you have any idea what's the problem?
Try leaving it plugged in and then restart the computer.
If you are on Windows this link may help but it is a bit old.

does any one have any idea what i should do it has been jailbroken for 3 months now i downloaded android lock and it started doing thisThat happens sometimnes with jailbreaking.
Jailbreaking voids the Apple warranty and also means that you will not get any support from Apple, including from this Apple forum. Jailbreaking can't be discussed in this Apple forum.
Unauthorized modification of iOS has been a major source of instability, disruption of services, and other issues -
I cant figure out how to authorize my office computer to download songs that I have purchased. A message saying I cant do it, but gives me no link to make it happen. Frustrating.Can someone help?
If you're running iTunes 11 and you don't see the menus, press Control-B or go to the small icon with the arrow at the extreme upper left and select "Show Menu Bar":
Apple for some inexplicable reason elected to hide the menus by default in the Windows version of iTunes 11.
I doubt that this will address a download problem, though. You'll need to provide more details about that; what device you're attempting the download on, the exact error message, and other such pertinent information.

I tried watching videos using various apps such as meta tube etc.. But after 10 secs instead of video "Q" water mark comes and sound goes on. Can someone help?
The only app you specifically mention is meta tube. No way to tell from the description on the app page where they source the material (I suspect primarily YouTube), and no reviews as of yet. You might want to contact the vendor.
If you are getting the same results from established streaming apps, such as YouTube or Jasmine, I would say you have a connection speed issue (keeping the stream from properly buffering). Hard to say.
Try a rest: Simultaneously hold down the Home and On buttons until the iPad shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the iPad back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset. -
hey guys ive got issues with my macbook pro that i bought not a year ago, and for the last week its just randomly restarting especially when im watching a video or using finalcut pro x can someone help me?
What do you mean "Leave them my laptop again"? do you mean you have had it worked on before? for the same problem or a different one?
You need to take it in to Apple ASAP. No matter how long they have it, you want it fixed and fixed correctly.

I have a Mac mini (bought in 2013) and the LG 20EN33 screen. I tried filing with the monitor's settings as well as the ones in display but the screen is stretched and the font is quite big. I saw a thread about Switch Res X so downloaded the app, but have no idea where to start to use it to correct issue. can someone help me please?
You monitor is
1600 x 900
and only have VGA input
http://www.lg.com/africa_en/monitors/lg-20EN33/technical-specifications
With Switch-X you want to change the resolution to match your monitor's resolution.
You have an old monitor and it may be best to get a new one that support the the now standard 1080p (1920X1080) resolution.
I have not ideal how Switch-X works since I use the free version of Display Menu fro the Mac App Store -
while trying to install latest itunes version i get this message "Older version of Bonjour can not be removed" and the download gets interrupted and doesnt finish. Can someone help?????
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any Bonjour entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?
