Tv out in windows 7 on Macbook Scanlines issue

While booting up to windows 7 on a "boot camped" Macbook, everything works fine except tv out on my tv. The picture get scanlines over the screen which makes it very choppy in high motion video. Probably caused by different the hertz set on the tv and output, though thats not the case because changing it doesn't change the problem except making them scan faster or slower over the screen. That also change with different resolution strangely enough. It works flawlessly in OS X so the hardware shouldn't be an issue either. Tried different nvidia settings but I'm out of options now. It's also updated till this day so it's not old drivers either.
Anyone having a clue?
Thanks in advanced!

Did you download and then install the Windows Support Software, in Boot Camp. (Page 1)

You may have to see about using the Recovery HD partition to attempt to erase and restore useful function of the capacity lost to the former Windows installation.
And you may have to backup your contents outside the computer to do it. Disk Utility on the Mac OS X historically has not been able to touch a BootCamp created partition; so if BootCamp cannot remove it, then you have to see how to do the equivalent of a reformat of the entire drive (less Recovery partition?) then reinstall your OS X. Maybe from internet recovery, then get your applications, etc from the Mac App store, etc.
A complete system clone of your OS X on an external HDD would be another method to restore after reformat, of the portion you want whole again, not necessarily the space where Recovery may live.
There may be (an)other way(s).
Perhaps someone with recent experience
in this matter can reply & discuss options.
With my antiques, they almost know what I want before I tell them.
Hopefully yours will after you talk to it awhile.
Good luck & happy computing!

My macbook froze up. Finger gestures work, but I cant close out of any windows. How do I close out the windows without using the track pad?

My macbook froze up. Finger gestures work, but I can't close out of any windows by clicking on the red "X". How do I close out the windows without using the track pad?

Command + W will close a window. Command + Q will quit a program.

Bootcamp assistant doesn't restarts to the Windows installer. Macbook pro 13" (early 2015)

I'm trying to install windows 8.1 on my new macbook pro 2015, things are good until I got to the point after I chose the size of partition then mac restarts. It supposed to reboot to windows installer as described in step 4 below, but it boots into mac.
I was able to install the windows to my macbook air before without a problem, hope someone could suggest what I did wrong here.
Followed exact steps from here - How to install Windows using Boot Camp - Apple Support
1. Check System Requirements
Some versions of Windows require a certain processor, and more hard drive space and memory (RAM) than others. Check the documentation that came with your copy of Windows to find out what you need. Then use System Information to see what your Mac currently has.
2. Create a disk image of your Windows disc
When you purchase Windows, it either comes as a disk image file (ISO) or as an installation disc. If your copy of Windows came on a DVD, you should create a disk image of your installation disc.
3. Open Boot Camp Assistant
Boot Camp Assistant walks you through installing Windows on your Mac. Open this app from the Utilities folder in the Applications folder and follow the onscreen instructions to automatically repartition your startup disk and download related software drivers for Windows. When prompted, connect your USB flash drive.
4. Format your Windows partition
When you complete the assistant, your Mac restarts to the Windows installer. When you're asked where you want to install Windows, select the BOOTCAMP partition, then click Format.
5. Install Windows
Follow the onscreen prompts to finish your Windows installation.
6. Restart your computer
After Windows is installed, you can switch between OS X and Windows. Use the Startup Disk preference pane in OS X, or the Boot Camp system tray item in Windows to select your startup disk, then restart your computer

Ok, I finally got the problem solved. It didn't mention anywhere that I have to restart and holding down the 'option' key, then go to EFI boot... hope it'll help someone with the same issue.
Cheers!

Install windows on my MacBook Pro7,1 (Version 10.6) **doesn't have an optical drive**

I recently replaced my HDD for a 1 GB SSD. Then I took out my optical drive and installed a HDD. I wanted the extra space to store videos and pic and such. I also upgraded the RAM.
I want to use bootcamp to install windows on my macbook pro. However, when I go to Boot Camp Assistant, its says "You need an optical drive to install Windows."
***I removed my optical drive and now have a HDD. I want to use a USB.***
SO, after I click continue... it gives me two options. Option 1 says Download the Windows support software for this Mac. Option 2 says I have the Mac OS X installation disc that came with my Mac or I have already downloaded the Windows support software for this Mac to a CD, DVD, or external disk.
My question is, HOW DO I INSTALL WINDOWS on my Macbook pro?
do I have to have an optical drive? that means, I have to take out my HDD and put my optical drive back in. Or can I just use a USB? if so , HOW?
Can I install Windows (7, 8.1) to a USB? Or download the Windows support software to a USB? and click on Boot Camp Assistant and click option 2? so when it asks me to put in the CD, I can just plug in the USB and install the Windows support software? and then put the codes in to install windows?
I hope I'm making sense. I saw several videos on Youtube and i just need some help.
Thank You.

So basically, I have trying to install windows on my mbp using a usb drive. However bootcamp wont allow me to do so since I have a optical drive on the laptop. I have been searching for a long time and eventually came across this solution and I would like to share this so u guys dont have to google all over the place again .
The solutions given before by changing info.plist is correct except that now Bootcamp crashes everytime you change it in OSX 10.9.
Full solution:
1. Add your Boot Rom Version(from system info) under DARequiredROMVersions.
2. Add Model Identifier(from system info) under PreUSBBootSupportedModels
3. Delete "Pre" from "PreUSBBootSupportedModels", so you have "USBBootSupportedModels"
The first 3 steps are same as before and if its not clear you can easily google solutions with screenshots.
The next step is only for OSX 10.9, as it employs some kind of code signature to prevent you from changing info.plist and cause bootcamp to crash.
4. Open your terminal, use the following command
sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app
Sudo means using administrator privilege and u need to enter your mac password. And the command resigns the bootcamp application so that it runs with the new info.plist file and not crash.
5. Continue on with your installation....
Cheers.
P.S. back up info.plist before u change anything.

How to get clamshell mode with Windows 7 on Macbook Pro?

Hi,
I am running Windows 7 on Macbook Pro using bootcamp. In OS-X, I can use this cool clamshell feature wherein after putting the MBP to sleep by closing the lid, as soon as I connect an external keyboard, mouse & monitor, I get the display on the monitor and immediately start using the keyboard & mouse too, converting the laptop instantaneously to a desktop.
I am trying to do the same thing on Windows 7, close the lid of the laptop to put it to sleep, connect my external monitor, mouse & keyboard, but however the laptop never wakes up (even after moving the mouse & pressing keys in the keyboard). I tried several things in Windows 7. Under Power Options, Disabled "selective Suspend of USB", but that did not help. Next, in the "Device Manager", for the "Root USB Hub" & "Generic USB Hub", I tried to set "Allow this device to wake up the computer", under Properties -> Power Management, but that option is grayed out. I tried to experimented with Sleep types like S1, S2, S3, but except for S3, the other two are shown as "not supported by firmware" (using powercfg option in command line). Countless hours wasted on google search to get this working with no success
I would greatly appreciate any help on this issue.
Thanks,
Sri

@mkultraviolent,
Thanks for the quick reply.
That seems to be a useful workaround, but I do not find the option mentioned in Display/ Nvidia control panel. However, I find an option in the "Power Options" which has a "Do Nothing" option in the combo box to select what "Closing the Lid" does. Is that what u are referring to?
Also, one problem in this approach is, if we do not sleep when the display is closed, that will keep the internal display (laptop's display) running in clamshell mode even after the lid is closed? (which will heat up the laptop badly).
The exact option I am looking for is, while the laptop is in sleep & lid closed state, connecting the external keyboard/mouse/monitor and pressing a key in the keyboard or moving the mouse should wake the computer from sleep. If this happens, the internal display won't be running. I am able to achieve this in OS-X.
In Windows7, I have a workaround by which I can almost achieve this result, wherein, while the laptop is in lid-closed, sleeping state, after connecting the external devices (keyboard/mouse/monitor), I open the laptop's lid for a fraction of second, quickly move my finger over the touchpad & close the lid again. This wakes up the laptop, & while it is waking up, Windows realizes that the lid is closed and that external devices are connected and gets into clamshell mode (I have verified that in this state, the internal display is not running).
This workaround was fine so far, but I got this hengedocks docking station for my macbook, and I am no longer able to use the workaround, because, after plugging my macbook into the docking station, I cannot open the lid. So, the only option is to make Windows7 realize that external devices are connected & wake up on external keyboard stimuli (Hence the question).
If my question is not clear, this video kind of explains what I want to achieve:

Installed windows 7 on macbook but im having a few problems...

I decided to install windows on my macbook since i want to play games and it is restricted in macbook...
So i installed windows 7 ultimate 32 bit, but i can't open the games i installed because of some directx problem, it literally says that i should install directx 9 which is required for the game. The problem is that i have directx 11 which is up to date and as far as i'm concerned if i have directx 11 i also have directx 9.
I googled the situation and saw that it might be related with some kind of "driver problem". It says that i need to update some of my drivers or something.
Im not an expert about these kind of stuff so i would really appreciate it if someone helped me!
I really tried hard to find a solution but i think i lack of some info, and i can't go any forward, so please help me out!

1 That's a Windows problem, not a Mac problem. You might get better help on a Windows forum.
2 You might have been better served to have installed Win7 64 than 32.
3 If the game wants DirectX 9 and won't work with DirectX 11, it might be a good idea to contact the game's vendor. Also, you might try downloading DirectX 9 from sites such as <http://www.softwarepatch.com/windows/directx.html>. (Note: download Windows drivers at your own risk. I have not downloaded anything from that site. I do not have any connection to that site other than knowing that it allegedly has DirectX 9 available for download. Use at your own risk. I'd back up before installing, but YMMV.)
Which game is this? What are the system requirements? Hint: some games which run in WinXP will NOT run in Vista or Win7. What are the hardware requirements?

Having Trouble installing Windows XP on Macbook

Hi! I've been trying to install Windows XP Service Pack 2 for the past 2 weeks now (first via VM ware fusion then with boot camp) but i keep getting the same stop error message with both:
"A problem has been detected and Windows has been shut down to prevent damage to your computer.
SESSION3INITIALIZATIONFAILED
If this is the first time you've seen this Stop error screen,
restart your computer. If this screen appears again, follow
these steps:
Check to make sure and new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any Windows updates you might need.
If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use Safe Mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.
Technical information:
* STOP: 0x0000006F (0xc0000020, 0x00000000, 0x00000000, 0x00000000)
After spending hours searching the web for a solution, I found out from the website below that it may be an issue with the original windows xp install disk so i did exactly what it says-- i made a copy using disk utility and burned it to a new disk but i still get the same error message. i did this numerous times. however the past few times, i couldn't even create a disk image because it kept giving me an "input/output error."
http://forum.onmac.net//showthread.php?t=837&page=2
Also, many times when i reboot with the install disk, the Macbook would spit out the disk on its own. Could it be an issue with my Macbook's optical drive?
I was so happy to get rid of the IBM Thinkpad that my college gave me so i can finally return to the world of Mac when I bought my Macbook after graduation, but now my job is requiring me to use software that is only compatible with windows so i need to windows xp running. my mother might get a new laptop to replace her ibook. i wanted her to get a macbook as well but she offered me the alternative of buying a PC so i can use that for work (i work from home). I don't want to do that unless its absolutely necessary, mainly because it is so much more conveniant to have windows on my macbook.
Any help would be appreciated. Windows has always driven me crazy!!!!!!!

Hi Anthony Kraljic,
This error is perhaps because your disk (HDD) has an error, Try to recreate the partition by deleting it first.(Also format it as NTFS during the windows install)
I hope this helps.

Installing Windows on a MacBook Pro

I want to use Boot Camp to install Windows on my macbook pro, is Windows 8 a good option?

Hello all,
I just bought a Macbook air 13 inch 2012, now trying to install Window 7. Since I'm more familiar with Windows, I have no idea of OSX and have a hard time to figure out things
I have tried Boot Camp, but doesn't have a Window 7 or ISO image,
Where can I download it?
Please help me
Thank you

Airport Extreme network with Ubuntu Linux (7.10), Windows (XP) and MacBook

Hi all.
My problem is that I cannot get Ubuntu to connect to Airport Extreme, see the hard disk(s) connected on it and print through it.
Airport extreme is connected to my adsl modem and I have an Ubuntu PC, Windows PC and a MacBook connected to airport extreme. Windows PC and MacBook work as expected. From the Ubuntu machine I can only connect to the Internet but I can't see the hard disks and printers. I think this is because I provided the modem's IP address to connect to (I chose Static IP in Network Settings and provided the modem's IP as a gateway). When I provide airport extreme's IP address as a gateway I am disconnected from the Internet.
To use airport extreme on Windows and macbook I used the installation CD, but it will not work on ubuntu. I installed airport-utils but it won't help, perhaps I am doing something wrong.
Any suggestions?

I suspect you have already found this out so this reply may simply be for my own memory recall in the future when I have forgotten it.
To connect to the network drives you need to open the file browser. Then from the Go menu select Network. You will likely see the AirPort Extreme Base Station show up as a cryptic name. Double click on it and you should see the shares.
For the printer I can't help as of yet since I haven't tried it yet.

STILL can't get Videos into 5G iPod , Ready to throw it out the window

I'm ready to throw this iPod out the window , I spent all day yesterday over 10 hours , trying to get videos onto my iPod , my iPod software and iTunes are up tp date , first I just drag and dropped them as MPEG no luck iTunes recognized and played them but wouldn't let me drag and drop them to the iPod then I used iSquint , it converted them to MPEG 4 , they transferd into iTunes and played but not the iPod I got an error that they weren't transferable and not recognized by the iPod .
I called Appe this morning and they were no help since I didn't get the Vid's from the appple store and since you only get one free service call ,and wouldn't tell me the format for the videos I didn't want to waste it . They suggested I buy Quicktime Pro .
Then I tried , Movies For My iPod . I used the transfer for iPod option , it converted them to .mp4.m4v . I drag and dropped them directly to the iPod no luck , they're there but wont play or show up in the iPod then I opened up iTunes and drag and droppped them into iTunes again played in iTunes not transfered to the iPod although it said it was updating .
Then ,I tried the custom settings file format MP4 , video format , MPEG-4 Improved , Image Size 320 X 240 QVGA , again I tried to drag and drop them onto the iPod still not there , now I tried to drag and drop unto iTunes , again they're there and play but won't show up on the iPod . I've pretty much had it .
In the Movies For MY iPod they're are some custom settings . File Format MP4(ISMA) In the Video there is an MPEG-4 Improved setting with a bit rate of 256 kbits/sec Image size 320x 240 QVGA frame rate 30 plus alot of other settings which I have no idea what they are .
Today I have 6 hours of frustration into this still no luck . I'm really disappointed with Apple ,I started out with the first iMac a Bondi Blue and have been working my way up , I have an iBook , an iMac Graphite , a G4 iMac a 15G 3G iPod now the 5G iPod . Apple should have included Quick Time pro in the G5 , and only one support call, come on , even Dell gives you a year of support .
And to top it all off the Black is beautiful but scratches easily , I'm a chef , my nails very short and allready it's scratched to bits by the wheel, I keep it in a case when I'm playing it , you can hardly touch it . I'm not very happy with Apple and this iPod , they rushed it out for the holiday , so if your in the jacksonville Florida area look for a flying iPod .

Lets run down a list of possibilities:
1) You are using iTunes 6 here, correct?
2) You did not say whether or not you are running in auto-sync, manual management, or "Enable Disk" mode. If you left it in the default mode as installed (auto-sync), then after dropping your movies into iTunes (or adding them to the Library), simply connect your iPod and allow it to auto-sync (mirror) the current contents of iTunes. (You can also try "Update iPod" option under the File menu, but I have found it unreliable -- possibly owing to "sleeping" iPod.)
3) Not sure if your reference to "dropping the movie on the iPod" is a reference to the iPod desk icon in manua/disk enabled mode or the iPod "Source" reference/associaed contents list in iTunes. Could you clarify where you are attempting to "drag 'n drop" and/or the selected sync mode of operation in your iPod Preferences.
4) As to conversion to iPod compatible formats, recommend you stick with MoviesForMyPod and/or iSquint if you are restricted to QT Pro 6 and not sure what settings to use for MPEG4 preset collection/QuickTime Movie full manual mode.

Cannot boot from usb flash to install Windows 8 on Macbook Pro 13"

Hi! All
I have a 2011 Macbook Pro 13" and I want to install Windows 8 on it. I use bootable USB stick, which I can boot fine from on my PC, so I assume it's not the USB stick that is a problem. First of all Bootcamp didn't recognise it. Fine, I partitioned the laptop's hard drive myself. Then while rebooting I held the Option key to manually select the USB drive, but it did not appear on the list. As someone suggested on the internet I even replugged USB stick to another slot during while on that screen, but it didn't help too.

Welcome to Apple Support Communities
You can install Windows from a USB drive in one of these Macs:
- MacBook Pro with Retina display.
- Mac mini (Mid 2010 and newer).
- MacBook Air.
- iMac (Late 2012).
You don't have any of these computers, so you can't install Windows through a USB disk. Its firmware doesn't allow you to start up from your Windows installation disk.
You have to buy Windows 8 on a DVD. You need a System Builder version, which you can buy at Amazon or NewEgg. Follow Apple's steps to install Windows on the MacBook Pro > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf
