OS 10.6.8 Upgrade causing wave pattern across screen

Just installed OS 10.6.8 upgrade on my MB Pro 15". On restart the display showed a wavy pattern of light and dark areas across the bottom of the screen. Re-booted again, and same pattern showed up. Rebooted a second time, but cleared the PRAM at the same time. On completion of reboot, screen turned black and keyboard lights came on. Computer completely locked up. Conducted a hard reboot holding the off/on key down - and computer rebooted clean, with no further problems of a wavy screen.

[this is me replying to my own post]
Just spoke to a very helpful person in Apple Support and am posting what I learned in case it helps others. The person I spoke to encouraged me to go to the Apple Genius Bar of a retail store in order to have the computer tested. Apparently there is a "known video issue" with some MacBook Pros that the OS 10.6.8 upgrade reveals. That is, the problem has been there all along but something about this upgrade makes it apparent. I'm scheduled for a Genius appointment later today and will post anything useful I learn.

Waves going across screen

When I have firefox open on my office computer (not the one I am using now) and visiting a webpage or even my bank account, there are distortion waves going across my screen. Sometimes only half the screen and then it will go to the entire screen. The waves go away for a few seconds when I change pages. If I use a different browser it does not do this. I tried uninstalling from add remove programs and re installed and it still does the same thing. I like Firefox but it is unuseable like this. I hope someone can help with this. Thanks

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

If this doesn't resolve it you most likely have a hardware failure. Fortunately, your phone is in warranty, so if you take it to an Apple store they will replace it.

HT4972 Why has this upgrade caused my data usage to go up?

Why has the iOS 5 update caused my data usage to increase so much?

I was wondering when the iOS 5.1 came out, not the new one that is out now. He did not say that downloading the upgrade caused the increase. He made it sound like new functions in the software caused it. Since Nov 2011 my data usage has increased from an average of around 30MB for the previous 7 months to an average of 136MB over the last 7 months. I have not changed the things that I do on my phone.

Why is os 6 upgrade causing my iphone battery to drain?

Why has the os 6 upgrade caused my iphone 4 battery to drain unusually fast?

when I use the computer usb port to charge the battery, I found something strange:
battery indicator is showing 100% from my iphone within a hour
battery indicator is still showing "charging" from iTunes after two hours.
After two and half hours, the battery indicator is showing "charged" from the itunes.
The battery indicator might make you think your iphone's battery is fully charged from the iphone but it doesn't.
I had same problem from my 4s after upgarded to iOS 6 but Charged the battery overnight or more than two or three hours and it works fine now.

Funny you should ask... At about the same time that the Xserve was discontinued, we also lost our channel rep of nearly 14 years. Right now we are not sure who our rep is. I have however, sent this to as many people in Apple that I could think of. And I plan on continuing to reach out to as many as possible.
The sad reality is that this decision is impacting customer deployments and the future of customer installations. Apple strives for market share and loves to tout those numbers. But the numbers we fought for over these last eight years are going to disappear.
As much as this impacts our business, we are making up for it in enterprise deployment of systems. We will survive and lead in our geographic area. I do not fear that. But OS X Server is a UNIX server and with it has come all of the benefits of a UNIX system, including legitimacy in a data center. The Intel Xserve cemented this reality because of its hardware configuration and form factor. Yes, we have G4 and G5s still in service. But those are mostly in all Mac shops that understand the benefits and can work around the buzz word limitations. But fortune 100/500 IT departments did not really get on board until the release of the Intel server.
Still beating the drum to raise awareness. Spread the word and talk to your Apple reps.
Also, ask about the direction that Apple's Enterprise team is going. If the news I hear is correct, then our fears about all things pro and enterprise going away are likely true.

Upgraded to Mavericks now iTunes screen is a negative. Background is black and titles etc. are white. How do I reverse it?

Upgraded to Mavericks now iTunes screen is a negative. Background is black and titles etc. are white. How do I reverse it?

Hello Tarpon471,
It sounds like your desktop is otherwise colored normally, but the colors in iTunes are inverted. I was thinking it is possible that a 3rd party plugin may be causing an issue with iTunes since the upgrade to Mavericks.

I have Aperture 2.1.4 on iMac OS X 10.4.1. I am getting a pattern across the entire image after clicking on a image in the browser in all projects.

Aperture 2.1.4 iMac OS X 10.4.1
Images look fine in Browser. When I click to enlarge I get a pattern across the entire image. This is true in all projects.
Out of curiosity when I sent the image via email w pattern showing on screen the email is fine-no pattern.

This may be an issue with the pde plugins. PDE stands for print dialog extension and are included with vendor drivers to provide access to printer features not supported by the core printing system. If you are using a Power PC driver (or sharing it from the G4 to the MacTel) then that may be a possible cause. See if HP offers a Universal Binary driver for your model.

Is my i7 MBP GPU malfunctioning? Strange pattern on screen?

Happens in the morning after the computer has been sleeping all night.
Diamond shape artifacting I guess?
Computer runs for about 3 minutes, then screen gets a strange pattern across it, then locks up.
Looks like this after the hard boot.

After I leave it on for a bit and let it warm up reset the power then it boots like this.
http://dl.dropbox.com/u/428893/Mbp/Movie%20Dec%2002%2C%209%2013%2043%20AM.mov
After it gets to the desktop things are really crashy and don't load properly, so a 3rd boot is needed.
After 3 reboots the problem goes away, so what ever it is I assume needs to warm up before it works right.
Its obviously hardware related, I suspect my logic board / GPU need to be replaced?
All this happens as soon as I move to Mexico where there are no Mac service places around!
Anyone know if mac will ship replacement parts for user serviceable components?

Unfortunately, this does have the look of a hardware problem, probably having to do with a graphics chip. Have you tried running the extended version of the Apple Hardware test? You might get an error code which would indicate where the problem is.
There is a way to contact Apple in Mexico--you might want to do that and see what options they can offer you:

Is it possible to upgrade my elitebook 8540w HD+ screen?

The one thing that has always bothered me about my laptop is the HD+ screen, I would love to have a FHD screen.
Is it possible to upgrade my screen to a dreamcolor2 version, and if not, is it possible to upgrade to a regular FHD screen?
One thing I've been able to find is the screen with part number: LP156WF3(SL)(B3)
This is an LG full hd screen, but I'm assuming it's not the dreamcolor.
Any help would be greatly appreciated.
edit: mod removed the part number thinking it was private information.

Hello KOL3N,
Your Elitebook is a Business model. Your issue would be best answered on the HP Enterprise Business Community Forums
Good luck!

After upgrade to iOS 8.3 screen reader in iBooks crashes

It happened on my iPhone 4S and iPad Air today After an upgrade.
When in iBooks, screen reader reads the page on the screen, finishes reading the text, turns the page but gives up (crashes?) immediately after. the reader "toolbar" simply disappears.
Before the upgrade it would turn the page and continue reading. Not anymore.
google doesn't seem to know anything about this.
Can anyone else confirm the behaviour? I tried it on several PDFs - the same behaviour.

Your observation is right. I am facing the same issue after upgrading to iOS 8.3. The trial and error was common with Microsoft .. it seems Apple is catching up with MS .
I hope they address this issue quickly.

When scrolling vertically there is an horizontal line which causes distorsion of the screen. I do not have noticed such concern on my iMac or on my macbook. What happen with the macpro ?

Photoshop CS6 selection, shape, and text is causing colored artifacts on screen

The Photoshop CS6 (13.0.4) selection, text, and shape tool causes colored artifacts on screen. I'm running on a retina Macbook Pro updated to the latest ML release. I have disabled GPU acceleration. I have also tried starting Photoshop with no plugins but this does not help.
I have created a video which shows the phenomena
http://www.youtube.com/watch?v=VG5ayC3WmKA

SOLVED. After two days of intense debugging I've identified the issue as an interaction between the ICC color profile, integrated GPU, and Photoshop. The ICC profile was created with an i1Display Pro using the i1Profiler software. The issue occurs when you create the color profile using the LUT setting. Creating a profile using the matrix setting seems to be ok. In summary, these are the specific conditions that cause the issue (for me):
1) Using a color profile created with the LUT setting with i1Profiler and i1Display Pro
2) Using the integrated GPU (discrete GPU is disabled in Photoshop Performance setting)
3) Running on Photoshop 13.0.4 (13.0+ all have the issue) on a 15" Macbook Pro with Retina display
Creating a new profile with the matrix setting OR enabling the discrete Nvidia GPU will also make the artifacts go away. The integrated GPU using the LUT based color profile does not seem to have any artifacts in any other photography and video editing software that I've tried so Photoshop is playing a role. The nature of the artifacts also change from Photoshop version 13.0 to 13.0.4. For example, in Photoshop 13.0 the Marquee Tool has no issues while 13.0.1+ has artifacts.

Just upgraded to Lion. My screen divider is no longer on my desktop. How can I get it back?

I saw that and almost replied, but I wasn't sure if it was the same problem because you referenced it happening when the "screen times out" and for me it was only when it was being activly used. Glad to hear I'm not the only one seeing this issue.
