I can connect my macbook pro to my tv with a VGA cable no problem. When I try to connect it to my tv with and HDMI it does not work, any solutions? It flickers once when first connect it, looking like it recognizes it, then it doesn't.

I am having trouble getting my macbook to connect to my tv. When I connect my mac to the tv via VGA I have no problem. It detects it right away. I just purchased a HDMI cable because I didn't want to have to use speakers when connect to my TV and it will not detect the computer. The HDMI is a good cable because it connects our apple tv to the tv, so I know it works.
When I connect the HDMI cable to the tv and my computer, the screen on my tv flickers once and it seems like it is connected. It then flickers one more time about 5 seconds after like it disconnects.
When I use my VGA it gives me an arrangement tab in the displays, I do not get that when I plug my HDMI in. I get nothing. Is there something else I could do?

Never mind, I solved it. Didn't know the converter needed a power source to operate (duh!) Now I have that, it works just fine.......

I want to change the settings (brightness, contrast, gamma) for my internal cam on Macbook pro. I find having to but a third party software (iglasses, webcam settings) to control basic settings as unnecessary and exploitative. Does anyone have a solution?

It is not about payment of $19.95 (Igalsses) or $7.99(webcam settings). This is a very basic setting that should be available in the system settings. The automatic setting of the internal cam does not work great on low lighting as everyone is aware.
i am just amazed how users take in lying down and suggest solutions such as paying for a 3rd party paid app or improving the lighting in your room.

Thank you I tried the reset again did not fix- I think I am down to calling Apple and paying for a tech - phone company says it is a software problem. I just updated to 8.1.3 - I thought the update might fix it.

Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
I have had this working previously but at the minute it seems to not be playing ball....any thoughts
Thanks
Dan

BUMP

Thank you for your help and time.

If you didn't back up the phone to iCloud or iTunes (on your computer) BEFORE attempting the update, the data will be lost.

You must have connected the Time Capsule with a router that does not work with my direct cable from my ISP

I tried to answer in your other post.. please stick to one thread ..
What method of internet do you have.. is this fibre install.. if so the TC should just plug in and use dhcp in router mode.. press and hold the reset and it will go back to router mode by default.

Hello there, TempestBelcher.
It seems you've covered all the bases, but feel free to review the iPhone Troubleshooting Assistant for connectivity here:
Apple - Support - iPhone - Calls Troubleshooting Assistant
http://www.apple.com/support/iphone/assistant/calls/#section_0
If you've followed all the instructions then there are a few good recommendations for what to do next in the last step.
Thanks for reaching out to Apple Support Communities.

Hello, the 'Save As' dialog box used to allow the backspace button to go up one level in the directory when the focus is in the folder contents box but it does not work any more, please help.

Hello, the 'Save As' dialog box used to allow the backspace button to go up one level in the directory when the focus is in the folder contents box but it does not work any more, please help. BTW the same 'Save As' dialog in other applications still allow the backspace button to go up one level in the directory.

cor-el,
I kept forgetting and procrastinating about following your instructions, since I have internet access only for limited amounts of time and usually I am busy with important tasks when I am.
Out of the blue, the problem corrected itself (the Save As box started to open full screen, then shrunk down to a normal size and the edges can now be dragged to a custom size).
Even the copy and paste problem in the filenaming area seems to have been less troublesome lately even though there have been no updates to Firefox in a few weeks.
Even though I marked the solution as not helpful, the problem has in fact been resolved. I will save the solution instructions in case the issue returns.

I keep upgrading and it still does not work - call me with a solution - now !!

I just need to take a few pages to take out of a document and create a new doc. I had the software and now it does not work. So i keep buying what I am told, by Adobe, will work, twice. Is this a continual scam to keep buying ??????????????????????????????????????
I need a solution now. If you can not help do not contact me, if you do not contact me I am going to discontinue the services I have. You have 24 hours. Today is 11/10/2014 6:34 EST.

Hi Paul,
I'm sorry for your frustration. You have an ExportPDF subscription, which you can use to convert PDF files to Word format. It does not allow you to remove pages from as PDF and create a new PDF. It looks like you may have placed an order for an Acrobat subscription today, but it has not processed. Once it does, you can download and install Acrobat, and then use it to extract pages from a PDF (choose Extract from the Pages pane on the Tools panel).
Best,
Sara

Try a hard reset and go from there. You might try a manual install (using DFU Mode), as outlined in the link below.

I'm going to assume that since you deleted your hard drive and all its files, you had a backup, yes? If the backup has an OS (bootable clone), then you can boot into it by holding down the option key when you start up you iMac and choose the backup drive. Then use Carbon Copy Cloner or Super Duper to copy the files back to your iMac.

Activation issues are almost always the result of a device that has been hacked or jailbroken. If that is the case, no support can be provided here.

How can you start up your ipod if holding the hold and home button does not work?

Remi,
How long did you hold these buttons for? Did you try more than once? Have you tried letting it charge for a bit and trying again?
