Screen stripes after 10.9.4 upgrade

Hi everyone
Ever since the latest Mavericks upgrade a few days ago, I have had an intermittent, but disturbing, problem with my MacBook Pro 17" (early 2011, 2.3GHz 16GB RAM). The screen suddenly does something peculiar involving the whole image shifting sideways, or vertical stripes appearing, and I can only turn it off with the power key. On turning it back on (normally, with Cmd-S, with Cmd-C, or with Cmd-R, it doesn't matter), I generally get vertical black and red stripes, or they might be pink and pale blue. Repairing the start-up disk and restarting rarely helps, an the problem returns. Usually, while trying to reboot, the screen goes entirely black or grey, with no key response, involving a hard shut-down again. After several efforts like this, I eventually get it to come back.
I have tried reinstalling the system using the recovery partition, and resetting the NVRAM, but have had this problem three times in as many days. Anyone else had this and know how to fix it?
Thanks, Pal

Mac Hangs on Screen Saver after 10.4.4 Upgrade

I scanned the board looking for this particular problem, but could not find it.
I recently applied the 10.4.4 upgrade to my iMac G4 (details below), and the upgrade seemed to go off without a hitch. However, I immediately noticed that my machine would often (but not always) hang when the screen saver kicked on. When it does hang, it hangs hard, meaning that I have to power the machine off to regain control.
Before the upgrade, the machine was working perfectly with no hanging. I repaired permissions and repaired the disk from the boot DVD both before and after the installation. I've also cleared the Safari cache, which was suggested in another post discussing a slightly different problem.
Is there anyone else out there with the same problem, or preferably, with a solution?

It could just be the driver has data corruption within it.
Anytime you have to force shut down, check to make sure the directory is in OK condition:
http://docs.info.apple.com/article.html?artnum=106214
When Repair Disk finds things to repair, that's the most common type of data corruption that can happen. Other types of data corruption are more insideous and may require a reinstall of the operating system. Sometimes data corruption which can't be repaired by Repair Disk, but is noticed by it needs to be repaired by Alsoft Disk Warrior. Note, repairing the directory should only be done on a system t hat is backed up.
In the worst case scenario, you may need to replace the hard drive as it is beginning to die. Sometimes issues like you've been having spinnning beachball you really need to wait out at least half an hour to verify that the computer just hasn't become busy doing something from third party software installs. If we knew more about what's installed on your system we could tell if that might be one of the causes.

I think you are sailing in uncharted waters with those kind of modifications.
I am only guessing, but if you have not already done so, do a PRAM reset and then trash your FCP preferences.

I've also notice when I start the computer up, it stays on the grey screen longer than it did when I had the original card (512 mb).
My understanding is the Mac is doing a ram/hardware test during the grey screen, if the card you added had additional memory, then it is very likely the test will take longer - but I am no hardware expert.

While doing a non-iTunes upgrade to 8.02 my iPad froze on the apple screen. After hours of waiting I forced a power off. Froze in same place. Tried attaching to iTunes on PC from power off. Freezing in same place. Any ideas?

While doing a non-iTunes upgrade to 8.02 my iPad froze on the apple screen. After hours of waiting I forced a power off. Froze in same place. Tried attaching to iTunes on PC from power off. Freezing in same place. Any ideas on how to get past this so that I can at least run a restore?

I Don't know that recovery mode would work, but did you try it?
If you can't update or restore your iPhone, iPad, or iPod touch
IF that fails, have you considered erasing the device using Find my iPhone in iCloud.com? I'm not sure what good that would do either of the iPad continues to freeze, but if nothing else is working .....

Screen distortion after upgrading to mavericks os

I own a late 2011 MBP 13". Last week I upgraded to Mavericks and regret it ever since. Firstly, it's become unbelievably slow. Secondly, and most importantly my screen resolution is now distorted and completely messed up. Immediately I suspected if Mavericks had screwed some setting. So I looked up Google for screen distortion after upgrading to Mavericks. The results were surprising! There are many apple discussions going on about the same thing. After reading most of them, as suggested in almost all threads, I took my laptop to the service station. The initial response given to me was that they suspected a hardware issue. All threads had indicated what to expect so I was not surprised. I explained to them clearly that there are discussions revolving around this topic and many users have been affected because of this. I even showed / shared the links of the various discussions on this topic. The service station in India asked for more time to investigate further. In the mean time I contacted the Indian call centre to report this problem. The service station reverted after their investigation that my logic board was corrupted and needed replacement. Phew!!! The cost of replacement is as good as buying a new MBP. It's really amusing because my MBP is less that 2 years old and unfortunately I do not have extended warranty.
Has anyone facing the same issue been able to convince apple that this is a mavericks issue? Does even apple recognize this as an issue in the first place? Does apple expect people to blindly invest in hardware just because they have released a new OS?
These and many more questions....
Expecting answers!!!
Not a good start to 2014

The startup disk may need repairing ...
Restart your Mac while holding down the Command + R keys.
From there you should be able to access the built in utilities in OS X Recovery

Completely unsolvable: Cannot change screen brightness after I upgraded my ThinkPad's display.

I have a ThinkPad X240 which came with a 1366x768 TN panel, I hated it and so after a while I upgraded it to an IPS 1080p display. It works great and looks fantastic except it's stuck on max brightness inside of Windows 8.1. I cannot change the brightness inside of Intel HD graphics settings or inside of programs like Display Tuner. It doesn't work in Windows 10 either. The weird thing is, I can change the brightness just fine inside of Ubuntu. I've tried uninstalling the Intel HD drivers and reinstalling them, I've tried switching the drivers to the Microsoft Basic Display Adapter, and none has worked. I feel like I've installed every single version of Intel's Graphics Drivers and that I've done everything and it still won't change the bloody brightness. NOTHING has worked except to just use Ubuntu, which is not an adequate solution. I've even gone as far as to update my BIOS and reset it to defaults, I've even pulled the CMOS battery. I've tried the version of the Intel HD driver from Lenovo for the X240 and I've installed the monitor.ini files. I've also just learned that during the Windows Boot Logo, the FN keys WILL change the brightness, but as soon as Windows is done booting, it stops working. This, coupled with the fact that brightness control works in Ubuntu means that this must be something related to Windows right? Brightness control works in BIOS. I've even gone so far as to try and change the brightness through CMD using powercfg according to this post. http://superuser.com/questions/472081/can-i-force-a-greater-screen-brightness-from-windows-command-prompt I'm really starting to lose patience now as it has been like this for 3 weeks and I can't be using Ubuntu all of the time, I honestly do not know what to do, it seems like this problem is completely unsolvable. Edit: I even got so frustrated that I switched off the laptop, installed the old screen, booted up Windows, and the brightness worked. Then (I know this is a bad idea) WHILE IT WAS ON, I pulled the old display and put connected the new one. And lo and behold, the brightness **bleep**ING worked in windows on the new display.

First of all you need to get into safemode
for that press f8 or del key while starting the computer
then you will get many options there you must go to safemode
Secondly ,after getting to safemode go to 1.control panel ->2.Device Manager->3.Disable AMD HD Graphics
Thats all
then restart your computer to get into normal mode
May be if you upgrade your amd hd driver your black screen problem will be gone

Satellite U400-22n and Win7 - screen hangs after 5 min

Hi, This is my first post
Ive purchased a new U400 with Vista preinstalled, last week ; 2 days ago Ive upgraded to windows 7 32bit professional when I stared Installing it windows prompted me that it requires a full installation , so I done a normal full install, windows 7 installed normally .
Now my screen hangs after 5 min and windows gos black and reboots after 3-5 min, Ive downloaded all the drivers from the Toshiba site Ive used the auto detect, and installed the drivers one by one and tested if the reboot stops , Ive reinstalled windows now 4-5 time returned my copy to the shop and got a new copy of the windows DVD, its the same,
Please has some one any advice for me. As the shop Ive perched this from will not upgrade to windows 7 for me.

hi Mather,
any bluescreens visible?
win7 32bit i guess...
you have to install all the drivers for win7 provided by toshiba in the right order!
first chipset and patchfiles if available...
i think a clean install will do the job!
make sure that the hdd is error free!
you can upgrade from vista 32bit to win7 32bit
but no chance to upgrade to a win7 64bit when a vista 32bit is installed...

Only "Headphones" sound, no speaker sound after 4.2.1 upgrading

After I had finished upgrading 4.2.1 firmware for my iPad, the speaker's sound has gone.
I can hear the sound from my iPad only when I connected to any headphones or bluetooth devices.
I tried many methods to get the sound back, starting from:
1. trying to plug in and out my headphone - nothing changed
2. switch on and off from the mute button (former is lock button) but it only showed "Headphones" or "Mute" sign.
3. shut down and turn on my iPad - nothing changed
4. Hard Reset my iPad and Restore - Still no sound, but I had to re-install everything again
5. Ask everyone and search every "no sound from iPad" topics but found none like mine.
However, while I upgraded the firmware, I noticed that I "locked" the screen during the process and I heard someone in the internet told me that it might be the origin of my problem.
I tried to sync my iPad and find how to re-upgrading the firmware again with no "locked" the button but there is no way to.

I've been having this problem for several months and just found this thread. Unfortunately the solution isn't well spelled out, but I was able to resolve the issue.
To recap:
Problem: Many/most non-Apple Apps have no sound from the iPad internal speaker. Plugging headphones in provides sound from all apps. Apple Apps (youtube, music, video, safari, etc) continue to function and play sound out of internal speakers normally.
Resolution: This issue appears to be related to the 'mute' / screen orientation lock button. If your iPad mute switch was on mute when you switched it to orientation lock, 3rd party apps will remain muted via internal speakers no matter what you do. Luckily an easy fix: Go Settings -> General and switch from 'lock rotation' to mute. Slide the switch to the non-muted position. You can now switch back to 'lock rotation' and your apps will play sound from the internal speaker again!!!

Welcome to the HP Forums MillaMagia,
I see by your post that the USB isn't being recognized.
I can help you with this issue.
Are you using the same USB cable? (known good USB cable)
You want to use the normal USB slot 2.0 cable and not the latest USB 3.0.
USB 3.0 are supposed to be backwards compatible.
Try another USB port on the Laptop, some of the USB ports are more powered then others.
I have provided a document to see if the printer is partially recognized in the device manager, which is causing the printer not to be recognized again. (the uninstall from the CD should have removed the entry and the printer from the registry)
Leave the printer turned on and the USB cable connected directly to the computer and the printer's power cord directly into a wall outlet.
How do I get into Windows Device Manager?
Here is a document for Identifying problems in Windows Device Manager.
Check to see if there are any hardware driver conflicts, you might see a ! mark or a red x beside a device with a conflict or unknown device, look under universal serial bus controllers, look for USB printing support or mass storage device, delete the entry by right clicking and select uninstall, OK.
Let me know how it was listed. (screen shots welcome)
If this is a Laptop then check the power management settings.
Access the device manager. Windows 8-How do I access the Device Manager.
Select universal serial bus controllers from the list, for each USB root hub, right click and left click on properties, for power management remove the check mark for "Allow the computer to turn off this device to save power". It allows the computer to limit or turn off power for this device.
Disconnect the USB, run the full uninstall and reinstall the printer software again.
If you need further assistance, let me know.
Have a nice day!
Thank You.

All the information that I had input on Quicken is gone. I have to have the external hard drive that I use to back up to be able to use quicken now. It is as if it was erased from the laptop hardrive

Try repairing permissions. My favorite way is with a utility called AppleJack. Info and download here. It's free. It only works when you boot in Single User Mode. When restarting or booting, hold down the Command key and S keys.
You will get a very different startup screen that looks like the Terminal app has hijacked the screen. Just let the lines of text scroll by. When that happens you will get a text entry prompt. Type in "AppleJack" without the quotation marks.
A DOS looking menu will appear. Choose 1 or d to run Disk Repair. If you get a message that Disk Repair found and corrected errors, run it again. Repeat until you get the "your disk appears to be ok" message. This rarely happens with my experience, though. This does the same thing as as booting from an external drive and running Disk Utility's repair. Only, no external drive is required!
Next, choose 2 or p to repair disk permissions. This will take a little while. AppleJack warns that it will take up to an half hour to run repair permissions. It'n never taken more than about ten minutes for my MacBook Pro.
As permissions are repaired, you will see each repair scroll on the screen. When done, the menu returns, choose q to quit. Then at the prompt, enter "exit" without the quotes. Your MacBook Pro should restart into Mac OS normally after this.
Hope this helps.

My computer crashed after an attempt to upgrade to Yosemite. I can't quit the installer and my MacBook keeps on restarting

My computer crashed after an attempt to upgrade to Yosemite. I can't quit the installer and my MacBook keeps on restarting

I Have a 2008 Macbook Pro 15". It was running issue free until I upgraded to Yosemite. Now my logic board is fried and apple will not fix it. It started with mail accounts unable to send mail, just had to delete accounts and re- install to fix that. But, at the same time as the download, I started intermittently getting a green tint over the screen along with a snowy static like an old TV set. Fearing that my download was corrupt, I re- installed Yosemite over-writing the previous version . The green haze kept coming and going, but I also started getting strobe style white flashes in boxes in the 4 corners of my monitor. I had to do power button forced shutdowns because of pointer and keyboard function failure. Apple Genius desk told me it appeared to be a logic board failure but my computer was too old for them to work onand referred me to a Mac Specialist Center. I was told by both places that Apple installed defective logic boards back then due to changing solder formula. They extended product warranty by adding 1 yr but that still expired in 2012. I tried to post a warning on Mac Forums twice about Yosemite being a poison pill to certain platforms and my posts were pulled. The second attempt was responded to in my personal email account stating that if I don't stop posting derogatory comments, I will be blocked from forum. I am just trying to insert warnings in posts where I can. They haven't discovered that yet. Spread the word!
