Have you dropped the iPad?
Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

HT201077 What causes videos not playing in photo stream?

Videos in my shared photo stream will not play they will load for a while then play for a second and stop. Anyone know how to fix this?

Welcome to the Apple Community.
Are they still uploading.

What causes videos to pause or freeze on You Tube?

I have Flash Player 10 ActiveX, Windows 7 and Internet Explorer (64 -bit). When I watch Fly Tieing videos on You Tube they will play 5 - 10 seconds then pause 15 - 20 seconds. This keeps repeating till the end of the video. Some videos will vary as to the time of playing and pausing but none will play continuously. I can restart the video and it will play without any pauses.
I was told to Uninstall Flash Player and download it again. I have Uninstalled, restarted, downloaded, and restarted twice and it didn't do any good. I was also told to go to where Flash Player is saved and start it from there and it would download properly. When I downloaded it both times the dialog box never appeared as to where to save it. I have checked my All Programs listings and it is not listed. The only place I can find it is on the Control Panel Uninstall list. I can't find where it is located.
I don't know very much about computers and would appreciate some help
It is sure aggravating when it takes 30 minutes to watch a 5 minute video.

Hi, thanks for the info. Do you know how to find the Flash folder? C:\Windows\SysWOW64\Macromed\Flash. Right click
on the Flash folder and post back all files listed there.
Also, Using IE, "View and Manage your Internet Explorer Add-ons", find All Add-ons. Look for Shockwave Flash Object...
ActiveX Control...Flash10e.ocx (this is the latest version 10.0.45.2) and make sure it is listed and enabled.
If you need direction to find the Flash folder, just post.
Thanks,

When using compressor voice is not sync with video. What causes this and how to fix it, please?

Although you say you have let the battery drain, was it for long enough? Since nothing else that you've tried so far has worked, I suggest that you leave the iPod unplugged for at least four days, preferably a week. That way, if something is stopping the iPod from turning the screen on, then whatever it is will drain the battrey. However, since the screen isn't on, that may take longer than if the screen was on.
Then, after that time, plug the iPod into a power source and leave it alone for at least thirty minutes. Only after thirty minutes will it show any signs of life, but you should leave it until it is fully charged before trying to use it.
If you get to this stage, the fact that the battery has drained will cause the iPod to reset when it springs back to life.
Let us know how you get on.

2012 macbook pro retina display artifacts on screen when using onboard video

2012 Macbook Pro Retina Display artifacts on screen when using onboard video.
About a month ago I've noticed these strange artifacts (blocky pixelated looking) running vertically down the screen. It first started when using Safari. Then it started to happen all the time. I turned off the auto switch video in preferences, which I'm assuming forces the computer to use the separate video card and the artifacts go away.
On top of that issue I also have had the ghosting issue.
Anyone else have this problem?

artifacts onscreen could mean a faulty gpu. You said by forcing it on inbuilt gpu you do not find this issue highlights that. Do take it in to apple for service and also tell them of your ghosting issue.
There are a few retina owners who have faulty gpus.

While using my imac the display just cuts off whats causing this

while using my imac the display just cuts off but the machine is still on and I have to push the power button a couple of times fir it to cut back on whats causing this?

Hi keithfromcapitol heights,
It sounds as if your iMac is going to sleep unexpectedly. Is this during use or after it has been left alone for a while (which can be normal if it is set that way?) If during use, I would suggest that you reset your System Management Controller, using the steps in this article -

No video displaying on my MBP

I bought my Macbook Pro last July. It's worked well since then. I had a minor run-in with Applecare because my battery was overheating and causing cracks in my top case. That same issue is happening again with my top case, and I'm not sure if it's related to this problem or not. I pray it's not because my warranty is almost up and I really do not want to go through those headaches..
Anyways, it started yesterday. After forcing shut-downs multiple times by pressing the power button till it shut off, the screen stopped displaying video. It started up again somehow and worked fine until this morning when I had closed the display to do things around the house. I came back and the video did not display. I get start-up chimes and that sort of thing but besides that, absolutely nothing.
Recent programs I installed were Blizzard's Wrath of the Lich King Alpha. An expansion pack in testing for World of Warcraft. The Alpha was crashing due to some Assertion error. Could that have corrupted software on my laptop and caused my display problem?
At the very least, could someone tell me what Apple Stores usually do in this situation? I am afraid to come in and have them tell me I won't be seeing my laptop for a month.

Try starting in Safe mode. If the problem is still there under a safe start, then it could be a hardware problem and you will have to get it fixed under AppleCare.

Update to OS 10.6.5 causing video problems with FCP

I stupidly updated to 10.6.5 this morning and ever since all video displayed in FCP appears to be underexposed by 5 or more stops. To give you an idea, it looks as if I applied 3-way color corrector and crushed the blacks 1/2 to 3/4 of the way down. This happens to all video in both the canvas and viewer window no matter what project I have opened. At first I thought maybe it was a problem with my graphics card but all of my qt files play fine. And if I go to the clips I am referencing in FCP they are fine when viewed through quicktime. I have tried the following:
move media to a different location and reference from there
install the combo version of OS 10.6.5
trashing my preferences in FCP
completely reinstalling FCP
none of these have worked.
I assume the other idea would be to reinstall my OS back to 10.6.4 but then I would have to wipe my hard drive right?
Very frustrating because I am in them middle of a project and now I can't work.

Someone will say "Restore your backup, the backup you made before you upgraded to 10.6.5." Just warning you.
I'm also using 10.6.5 but I've not seen what you're describing. Maybe something is that more specific to your setup is causing it. If you export a QuickTime movie is it also fine or is your video output fine? If it is then you can keep working, because you know that the problem isn't affecting your output.
Going back to 10.6.4 may be the thing to do, and yes you'll need to wipe your drive. So back up your system as it is now just in case the 10.6.4 reinstall fails spectacularly.

What causes a slow mouse/cursor response on a fast machine?

I have a system that has always displayed poor cursor redraw performance with certain adobe applications. All rendering and other effects are fast, but basic mouse selections and button knobs are extremely unresponsive. I have searched and searched and can not seem to find out what causes the mouse cursor speed issues. Does anyone have any ideas as to why my mouse would slow for such basic Interface interactions? Do I need to change my hardware, settings, displays, BIOS, etc?
Any insight into what the mouse redraw/refresh is called in terms of computing would help me search for a solution. And if you have a solution as to why my mouse cursor acts drunk and sluggish when interacting with the Adobe UI's in premiere and after effects and sometimes Photoshop I would greatly appreciate the help.
Thank You. I attached a screen shot of a very basic selection interaction that is dog slow. The selection box redraws like there is a lag in some process associated with the square box overlay.

It takes a long time to draw and redraw the pixels to the screen(s) with such large monitors.
We can mitigate this by making some changes in how our UI is drawn to the screen, and such changes are a rather high priority for use to work on for the near future.

Mac Mini (Mid 2011) display artifacts HDMI to DVI at native res

Hello,
I recently changed monitor configurations and in the process moved my Mac Mini (Mid 2011) to a HP LP2065 monitor. The connection is made through the stock supplised HDMI to DVI adapter.   The monitor and the DVI cable work successfully with other machines.
What occurs is only certain colors, usually black, result in the display being red and/or sparkling and/or static (like TV static) when the monitor is set at its native resolution of 1600x1200.
If I bump the resolution down to 1280x1024, or lower, the black color returns and I see no display glitches.   If I bring the resolution back up to 1600x1200, the display artifacts return.
A few google searches suggest I use a DisplayPort to DVI adapter instead as some monitors are "finicky".   Does anyone agree with that? It seems peculiar to me -- why would a digital signal have analog-looking glitches?
Any ideas welcome.. thanks for reading

Your monitor has a native pixel resolution of 1920x1200. There is no point in trying for 1080-p or -i.
I run two 1920x1200 monitors via HDMI (with passive cable adapters where necessary) and I use these choices:
...and they are both pixel-sharp, filling the screen, and yet menu bars totally visible!

What caused the iBook problem?

I'm writing this for my wife, as she's unable to use her iBook for more than a few minutes before it locks up.
I'm serving in the military overseas. My wife and I both use Apple products to chat, email, etc. When I spoke to her yesterday, she was frantic. Her iBook G4 apparently started making a strange noise and then stopped working altogether.
I asked her what she had tried, and she explained that she spent over an hour on the phone with Apple support (I knew AppleCare might come in handy). The first support person she spoke with was, for lack of a better term, an idiot. This was confirmed by the third support person she spoke with. I'll explain later.
The problem was that when she tapped her spacebar to wake up the computer, it didn't wake up completely. She got a grey screen, Apple logo, and that was it. I told her to be patient, that maybe it was reseting after an update (that was before I knew about the 10.4.6 update being available).
Her computer auto-updates every Monday.
I had her turn off the computer by holding down the power button. I then had her disconnect the power cord and remove the battery. I did this on a hunch (just in case the computer had a heat problem). She reconnected the power cord, pressed the power button, and it was back up and running - for about 5 minutes.
Then the computer began making a not-so-funny noise again, and the spinning-beach-ball-of-death reared it's ugly head and wouldn't go away.
The first support person had her use the install/boot disk that came with the computer. That was Panther. We're using Tiger. Bad idea.
When the boot/install disk did not appear to be working, the first support person had her abort, and she was prompted with little phrases like "are you sure you want to quit, doing so now may damage your files" or something like that.
He just had her keep clicking "OK" and eventually got tired of talking to her and told her the hard drive was bad and that she was SOL.
The second support person was apparently too busy to troubleshoot any further and cut directly to "sorry, you're SOL".
The third support person was a little more helpful in that he talked her through connecting the iBook to her G5 PowerPC iMac to attempt pulling the files over to the iMac (she had already resigned herself to the fact that the iBook hard drive was on it's last leg).
She had asked the first support person about doing this and he said that if the files were corrupt on the iBook, they might corrupt the iMac, and that it was a bad idea. Not a very bright guy, considering the files would be copied to a folder, and wouldn't overwrite the iMac's system files.
She started to transfer files and the iBook froze again. She repeated the steps I had her do earlier, managed to get a CD in the the drive, copied a few folder successfully to the CD, checked the CD to see if the files were there (success!) but then the iBook died before she could get the CD out. She's working on holding down the track pad button while rebooting to see if it'll spit out the CD as I type this.
So, in addition to wanting to know how to resolve the problem, I'd like to know what caused it.
What caused so many people to have alleged hard-drive problems within a day or two of each other?
Is this Apple's first virus?
Is this the work of a disgruntled Apple employee working in the updates department?
Is this an evil Apple plot to force us to by MacBook Pro's that won't run Virtual PC?
Will running the 10.4.6 hurt or help the situation?
Why is there such inconsistency in Apple support and aren't they supposed to log their trouble-shooting steps performed thus far?
My wife has been using Mac's for over 9 years. I've only been using them for 2 years. Up until now, I've had a lot of confidence in Apple to be a solid platform, even if not the fastest platform. This experience is not inspiring me to purchase another Apple computer.

Hi Robk64,

Do you have the Tiger Install Disc?
SOL?
Her files probably won't fit on a CD; unless she has less then 700Mb.
1."Is this Apple's first virus?"
Negative
2. "Is this the work of a disgruntled Apple employee working in the updates department?"
No, I don't think so. Apple tries these out to try and avoid problems with their updates. Things happen that are not expected. They wouldn't put anything out unless they thought it was ready.
3. "Is this an evil Apple plot to force us to by MacBook Pro's that won't run Virtual PC?"
First off, look at #1 and think about what platform is notorious for virus problems (Mac has had not had any virus out breaks so far). There have been some "malware/macro" software that was meant to mess with Apple Computers. The most recent that was was over exaggerated was nothing special; MacWorld worked pretty hard to get it to effect their machine. As long as you know what you are downloading and where you are getting it from, you should have no problem.
If you want VPC to work on a MacBook Pro; don't look to Apple. You should talk to Microsoft's Mac Department because Apple announced the Universal Binary switch a long time ago (with developer help) so that software companies could make the switch easier. If anyone is to blame; its Microsoft [they are busy working out their problems with Vista; I am guessing it will be awhile before you see VPC for MBP;) ]
"Will running the 10.4.6 hurt or help the situation?"
My opinion would to just reinstall Mac OS X after backing up the hard drive. That would probably fix your problem. Once OS X is installed; update the software.
"Why is there such inconsistency in Apple support and aren't they supposed to log their trouble-shooting steps performed thus far"
Once in a while Apple's personnel may make human errors. The second one you talked to may have seen her work-up and just reiterated what was said. They have resources we don't, but they can't really go beyond them because they can't see the product, and they are just call support. You may have to send it in.
So in 9 years, you have had this one problem. We can't really tell you what is wrong with the computer because we can't see it ourselves; we can only give suggestions/ideas. Tell them her story, explaining her situation (military etc) and then see if they can help. She may want to bring it into her local Apple Store/Reseller. She can make a reservation on the website or at the store. She can get better feedback in person.
Just some of my thoughts,
Jon

What causes BUFFER GETS and PHYSICAL READS in INSERT operation to be high?

Hi All,
Am performing a huge number of INSERTs to a newly installed Oracle XE 10.2.0.1.0 on Windows. There is no SELECT statement running, but just INSERTs one after the other of 550,000 in count. When I monitor the SESSION I/O from Home > Administration > Database Monitor > Sessions, I see the following stats:
BUFFER GETS = 1,550,560
CONSISTENT GETS = 512,036
PHYSICAL READS = 3,834
BLOCK CHANGES = 1,034,232
The presence of 2 stats confuses. Though the operation is just INSERT in database for this session, why should there be BUFFER GETS of this magnitude and why should there by PHYSICAL READS. Aren't these parameters for read operations? The BLOCK CHANGES value is clear as there are huge writes and the writes change these many blocks. Can any kind soul explain me what causes there parameters to show high value?
The total columns in the display table are as follows (from the link mentioned above)
1. Status
2. SID
3. Database Users
4. Command
5. Time
6. Block Gets
7. Consistent Gets
8. Physical Reads
9. Block Changes
10. Consistent Changes
What does CONSISTENT GETS and CONSISTENT CHANGES mean in a typical INSERT operation? And does someone know which all tables are involved in getting these values?
Thank,
...

Hans, gracias.
The table just have 2 columns, both of which are varchar2 (500). No constraints, no indexes, neither foreign key references are in place. The total size of RAM in system is 1GB, and yes, there are other GUI's going on like Firefox browser, notepad and command terminals.
But, what does these other applications have to do with Oracle BUFFER GETS, PHYSICAL READS etc.? Awaiting your reply.Total RAM is 1GB. If you let XE decide how much RAM is to be allocated to buffers, on startup that needs to be shared with any/all other applications. Let's say that leaves us with, say 400M for the SGA + PGA.
PGA is used for internal stuff, such as sorting, which is also used in determing the layout of secondary facets such as indexes and uniqueness. Total PGA usage varies in size based on the number of connections and required operations.
And then there's the SGA. That needs to cover the space requirement for the data dictionary, any/all stored procedures and SQL statements being run, user security and so on. As well as the buffer blocks which represent the tablespace of the database. Since it is rare that the entire tablespace will fit into memory, stuff needs to be swapped in and out.
So - put too much space pressure on the poor operating system before starting the database, and the SGA may be squeezed. Put that space pressure on the system and you may enbd up with swapping or paging.
This is one of the reasons Oracle professionals will argue for dedicated machines to handle Oracle software.
