HT1349 After installing windows 8, I have no sound on my mac desktop. Need help?

Hi,
I recently installed Windows 8 and after the installation there is no audio (sound) in my iMac. I can't hear youtube videos, mp3 files, no nothing.
Suggestions to solves this problem?

As you sure that you don't have system sounds muted? If you have sound in the music app, then system sounds are muted.
If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.
This support article from Apple explains how the side switch works.

Cannot install windows 8 because the disk is in MBR partition. Need help.

I am on a MacBook Pro 13" Early 2011. I am trying to install Windows 8(OEM) using bootcamp witht a USB. I made the USB bootable from the Windows Usb tool, and made the Bootcamp partition through bootcamp. I hold down the option key at startup and select the usb. It starts the setup, everything is fine untill I select advance option to install and select the BOOTCAMP partition. It says you need a GUID partition table to install but I have MBR. I have checked in disk utility and the partition map scheme is GUID partition table. Do i have to format the whole drive to fix this? That really isn't a problem. Also, FYI, this mac recently had its logic board replaced by apple. Could that have anything to do with it?
I have been stuck on the problem for days and it is getting really frustrating. Any help is appriciated. Thank you.

Hey there, I have the same problem as Noor440 discribed, just that I burned a dvd with Windows 8 and it doesnt work. I can boot it from the CD in EFI mode but then it happens the same as with Noor. I can't install it because of MBR and its asking for GPT.
The thing is that when I try to boot from the regular CD (not in EFI mode). My screen goes black and I can't do anything about it.
I read in different posts that to install WIN7 or XP I have to have my optical drive at the original place just that I removed it in order to install an additinal SSD.
Is there no other way than to open my macbook again put the SSD in the place of the original HD (at the moment it is in the slot of the optical drive) and then partition my SSD with bootcamp, install Win 8 and change the optical drive with the HD again. Last but not least I would need to redo the syslinks as well ...
would be nice if anybody has some good suggestions wether I can avoid that all ...
thanks a lot

could someone decipher these for me? do I have a keylogger?
thank you

It's best to describe the problem in as much relevant detail as possible, rather than what you think is causing it or how you think it should be solved.

Getting camcorder video on iTouch? I have a PC, not a Mac and need help

I am getting my wife the 32GB iTouch for XMAS and hope to be able to get some of our video footage of our 15 month old on her iTouch. The video was taken in AVCHD format (highest resolution) on my Canon HG10 camcorder. Video support for the camcorder is as follows:
VIDEO SUPPORT: H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; H.264 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Baseline Profile up to Level 3.0 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
I also have many JPEGs in 10 megapixel resolution taken with my Canon Powershot G7 camera.
Because i have a PC (Sony Vaio), will I be able to get the camcorder video and camera pics onto my wife's iTouch? I assume I may also need to downconvert the video resolution from the 1920 * 1080 HD high res fomrat. What software or conversion device will I need? Someone mentioned a free shareware converter called "Super" (just Google "super") which might help???
Any and all help will be much appreciated.
Happy Holidays and thank you,
John

Hi John,
It really is pretty easy. The Ipod touch won't take the highest resolution, which is why it needs conversion. I also have an XP machine, and the easiest way to get home movies into iTunes is to pull them up from "my documents" and open the file, selecting iTunes or QuickTime as the player. Either option will open your itunes library and put the file there. My computer allways complains for a minute when I do this, but it settles down and does it just fine. When it starts to play, stop the video and it will be in "movies" in your iTunes library. Now you're ready to click on the advanced tab and convert. For converting high def video, be aware this may take awhile. It is worth it though-I love watching my home movies on the touch. Good luck! Let me know how it goes!

After installing Windows 7 my desktop Adobe icons have change in appearance. How do I change them back?

After installing Windows 7 my desktop Adobe icons have change in appearance. How do I change them back?

The file icons is one on the change features MS removed from the Explorer options. Supposedly you can do the change with the registry, though I have not figured out that option. If you want to try, backup the registry first and then you might try the instructions at How to Change a File Type Icon in Windows 7 and Vista - The Winhelponline Blog. If the application icon is not correct, try to fix that before the approach above. Good luck and be careful (dealing with the registry can make your computer not work..

What DVDs are this ?
If it is OSX Snow Leopard Installation DVD then yes this disc contains the BootCamp Drivers version 3.x and is needed after the installation of Windows to install the BootCamp Drivers.
With OSX Lion BootCamp is at version 4.x and the BootCamp Drivers have to be downloaded during use of the BootCamp Assistant in OSX.

A lot of problems after installing Windows XP using Boot Camp on a Mac Book

I have been having a lot of problems after installing Windows XP Home Edition (2002).
For one, after installing Windows using Boot Camp with Mac OS X 10.5.1, I opened Windows on my Mac Book, inserted the Mac OS X Disk 1 as in the instructions and got the message: +"This package requires a newer version of the Windows installer. Do you want to update the version of the Windows Installer on your system?"+ When I clicked Yes (I had NO idea what it meant at the time), I got the message: "The required resource 'UPDATE' is missing" and the Installer quit.
How do I fix this problem?
Another problem I have is that there is no sound on the Windows XP, yet it works perfectly on Mac OS X. Is there any way to fix this problem?
A third problem I have is that I can't wirelessly connect to the internet using Window XP, yet I can on Mac OS X. I have no idea on how to fix this, and it's really messing with me. D:<
D: There are way too many problems, and I have a feeling there will be a lot more later on. Help....

Do I need to install boot camp on Windows 7 as well as on Lion? I already installed it some years ago on Leopard when installing Windows Vista on my Macbook Pro. But now after installing Windows 7, many things in windows doesn't work (sound etc.)

Do I need to install boot camp on Windows 7 as well as on Lion? I already installed it some years ago on Leopard when installing Windows Vista on my Macbook Pro. But now after installing Windows 7, many things in windows doesn't work (sound etc.). I made a clean installation because I needed to go from 32 bit to 64 bit.
Or should I just update bootcamp in Lion? (cause when I search for "boot camp" in Windows 7 there's no result)

How can I partition internal HDD after installing Windows 7 Professional via Boot Camp 4.0?

I recently purchased MacBook Pro 13" (Late 2011) model with OS X v10.7.2 Lion installed. I've upgraded to OS X v10.7.3 Lion and updated all other software.
I require Windows 7 for some Windows based softwares that do not support Mac OS X. Therefore, used Boot Camp 4.0 to install Windows 7 and then tried partitioning single internal HDD to have 3 partitions (4 total including BOOTCAMP partition). Disk Utility created a 648.5MB partition and then I was able to create 3 other partitions of custom sizes. After applying these changes, I got an error message that said selected volume size is too small. I resized this 648.5MB partion to a custom size and had total 4 partitions, including BOOTCAMP.
After reapplying these changes, BOOTCAMP partition was removed and I was left with only 3 partitions and empty space.
I've tried several different ways to partition the disk, all in vein. Is there a way I can partition my single internal HDD after installing Windows 7 Professional via Boot Camp 4.0?

You can't do what you want with GUI utilities, which will only allow a total of 4 partitions due to the limitation of MBR needed to support Windows. Those four partitions: EFI System (hidden), Mac OS, Recovery HD (hidden), Windows. So with Lion, you only get two visible partitions if you're going to use Windows with BootCamp. You can't make anymore with the included graphical tools.
If you need more partitions you'll need to use something like GPT fdisk (gdisk) to create the partitions in the GPT first. Then add the Windows partition only to the MBR and flag it as bootable. gdisk can be googled and downloaded for Mac OS X off sourceforge. It is not a GUI tool.

But when I restart the machine and choose to go into windows, it just can not boot, saying no bootable device. If I insert the installation disc into the drive, then I restart and go to windows, it can boot successfully.
Please Help.
Much appriciated.

While we all have MacBooks in this forum not all of us use BootCamp. There's a BootCamp Support Community where everybody uses BootCamp. You should also post this question there to increase your chances of getting an answer.

How Can you reinstall Photoshop Elements12 to a computer that its was there but loss it after installing windows 8.1

How Can you reinstall Photoshop Elements12 to a computer that its was there but loss it after installing windows 8.1

Reinstalling Mavericks depends on several factors:
if you erased your recovery partition
what OS originally came on your Mac.
I'll assume you don't have a backup available that you made before your mishap, because you didn't mention it.
That's really the take home message here: have a backup!
If you still have your recovery partition:
boot into the recovery partition (command R at restart)
use the recovery partition to reinstall Mavericks. see: OS X: About OS X Recovery
if you do not still have your recovery partition, then it depends on whether your Mac originally came with installer disks or not.
If it originally came with installer disks, you would boot from the installer disks, erase your HD, and then reinstall the OS that is on the installer disks, and then upgrade as necessary until you get to Mavericks.
If your mac did not originally come with installer disks, but you managed to erase your recovery partition, then you can try to boot into internet recovery (option-command-R at restart), and use internet recovery to erase your HD and reinstall the OS that originally came with your computer, and then upgrade to Mavericks if you need to. See: Hands on with Mountain Lion's OS X Recovery and Internet Recovery | Macworld
(the reference refers to ML but it applies just as well to Mavericks).
