Within the last hour, I noticed that my older MacBook Pro, while I was using iTunes, lost contrast on the screen. I am sorry, but I did not take exact notes on this event. Around the same time, I did do a back up, uploaded Apple software, etc.
I'm using two MacPros simultaniously, the old one for iTunes, and the new one for the other things. My new one has no problems, so am wondering if there is an easy way to correct the older MacPro's contrast problems. The computer is over three years old, and I'm wondering also if this failure is an aging sign. (I also have other problems, such as a noisy DVD drive, which is part of the reason I bought a new MacBook Pro.)

Is the older MBP a pre-Unibody model from early 2008? If so, it could be having this problem:

If so, you would be entitled to a free repair.
The lost contrast could be considered distorted video.
Do you have an external monitor? If the external shows the same lost contrast, the graphics chip is likely the culprit. If the external is OK, then you probably have an issue with the built in display or possibly with its connections.
You may also want to check in Universal Access to see if the contrast bar is set in its normal position (all the way to the left).
Apple has a special test they can run to diagnose the NVIDIA issue, so if you have access to an Apple Store, make an appointment at the genius bar to have it run.
Good luck!

I have updated Adobe flash plug-in but it continues to crash. It has crashed on me over 3 times in the last hour; why is that? Is it firefox?

I have updated Adobe flash plug-in more than once, but it continues to crash. It always does it right in the middle of a game or something I'm playing. Now, I pay real money to play these games so that I can purchase certain things, so this is now frustrating me. If it's firefox that keeps adobe crashing please let me know so that I can go back to using internet explorer.'''bold text'''

James j,
You have a different problem. Your screenshot shows "The Adobe Flash plugin has crashed".
See [[Plugin crash reports]] and [[The adobe Flash plugin has crashed]]. If you need more help you should [[ask a question|ask a new question]] (start a new thread).

Which was the last version of Firefox that Supported Java Platform 6 ?

I want to know the the last version of Firefox that Supported Java Platform 6 update 45 (Java SE Runtime Environment 6u45) ?
In other words which version of firefox started support for Java 7 ?

Please also give links to the problem pages if they are public so that we and others may test them. You could also consider contacting the sites concerned directly yourself.
Using Java can raise security concerns,and especially so using outdated versions.

Firefox is hanging and must be shut down very frequently. Over the last hour, it happened 15 times at a wide variety of sites (gmail, wikipedia...)

Firefox is hanging up very frequently (15 times in the last hour). When it hangs, the page stops loading (spinning icon on tab stops) and all windows of Firefox are non-responsive.
It seems to be random sites from gmail to wikipedia to some forums. I have tried everything mentioned on the "Firefox Hangs" page. I am sure that more information will be required. Can Firefox do a memory dump when it hangs?
== This happened ==
Every time Firefox opened
== only a couple time last week, today it it much more frequent

hi again, thanks for the further reply. i have had a look at the website you suggested and the repairs look okay to do. just one more development/question
the day after my original post, the problems seemed to have gone away. but yesterday it started again.
the new thing even with the adapter plugged in, the battery says 0% and shuts down soon as i unplug the adapter.
so looking at the computer info, it says:
AC Charger (Watts): 0
Connected: Yes
Charging: No
and above that:
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 4310
Remaining Capacity (mAh): 8
Amperage (mA): 0
Voltage (mV): 10932
Cycle C*ount: 7*
*AC adapter cannot charge battery: Yes*
do you know why it wont charge the battery? is this linked to the same solutions you suggested?
thanks again for your help! I really appreciate it

I have spent the last hour trying to upgrade my Iphone using ITunes. Now, my phone will not work at all. I think the backup is on my computrer, but it appears now to upload. What to do?

I have spent the last hour trying to upgrade my IPhone to IOS 7 using ITUnes. Now, my phone wil not work at all. I think it is backed up on my computer, but I am unable to get it to download to the phone. What to do?

Thanks, as it still will not work, I assume it is damaged and needs to be sent in for repairs.

As a new Macbook Pro user I was saddened to find that the feature of using keywords in iPhoto '11 does not allow showing same under each photo. I understand this was available in earlier versions. Any comments?

Against TOU which you "agreed" to in order to post in these user to user forums. If you want to "suggest" something to Apple, do so in the Product Feedback area.

Instead of getting annoyed, read the User's Guide and try basic troubleshooting.

Is it possible to put the photos on my iPhone 5 onto my MacBook Pro? The photos that I am trying to do this with we're not taken from the phone. They were imported from a computer.

i got an iphone 5c last saturday. i noticed that after merely 5minutes of using facebook, my phone got warmer than the usual. i know that phones will get warm if being used but getting a warm phone after just 5minutes of surfing with 3G seems not normal. compared it with iphone 5 and 5s and they are not getting warm like that. is it a software or hadware issue?

My eyes just glazed over...Please in the future break down each of your issues with paragraphs separated by two carriage returns. It would be much easier when trying to address your issues.
Go to Apple menu -> System Preferences -> Keyboard and Mouse -> Mouse
And edit your mouse settings to do what you want it to do.
Secondly, this is not the place to vent. If you have a complaint, there is:
http://www.apple.com/feedback/
or http://www.apple.com/contact/
We are just end users here helping other end users.
Third, from my understanding, it would appear you are concerned about the noise the hard drive makes when it falls asleep? Why not put your machine in screen saver mode instead? Apple menu -> System Preferences -> Energy Saver turn off all Energy Saver settings, or set them to run Never.
Fourth, if your machine was purchased just a few days ago, you may still be able to get an exchange from the store, quicker than you can get a repair done. You may want to look into that possibility.
Fifth, it does appear you found the Logic forum. I would persist in asking there how to solve your technical issue with Logic regarding the audio. It may be you don't have to do anything special to the hard drive. Remember audio can be transmitted by wire, avoiding ambient sounds.
Good luck!

My iPhone 4S will not update it will start and at the last hour it says error what can I do

Everytime I try and update my iPhone 4S to ios7 it will start to download and at the last hour it will say error update failed i have tried everyday for the last week

You either need to go somewhere with a MUCH stronger and faster WiFi signal or do the update using your computer and iTunes.
On my PC the download took 10 minutes,

Averaging over the last hour and last eight hours.

This is fairly simple but I'm not sure what a "good" approach is. Basically I need to track how many times a user has performed an action over the last hour and last eight hours. I'll receive a notification of some sort when they perform this action and could get the current time, but I'm not sure what a fast way of determining how many times this has occurred in a given time period is.
I was thinking perhaps an array with the time of each in milliseconds and just find the first index that was < 8 hours or < 1 hour ago and then subtract the index from the current size. I think that would be problematic though. To keep the array from continuously growing I'd have to shift everything over to the left which means an expensive arraycopy. Perhaps if I only did the resizing when there were > 20 or elements I no longer care about or something would help, but then I'd have to iterate over 20 elements I don't care about everytime it's calculated, which is once a second.
Any algorithms that will solve this?

Here is a method with a granularity of a minute (i.e.
it only updates the average value every minute - you
can change it to give whatever granularity you want)
Keep an array with 60 elements in it. The array
counts the number of times that the user performed
the action each minute.
The array in indexed modulo real time, and you make
entries based on actual time of day. So when a user
performs an action at 8:38:45 you increment slot 38.
Each slot counts the number of actions that took
place in that particular minute. When the next minute
rolls around, you move to the next slot, set the
value to zero (thus throwing out the events that
happened over an hour ago, and prepare to count the
new events)
The sum of the entire array is of course the total
number of events that have taken place in the last
hour.
You do not need to actually run through the array and
total the events every time you want to calculate the
average. You can use the fact that you increase the
total by one every time you get a new event and you
decrease the total by X everytime you zero out a slot
that had X for its event count.
So you can just keep a single value, Total, along
with your array that goes up by one on every event
and then drops back a little every minute, when you
throw out the hour old events.That is probably a good solution to the question I posed, but I realize now I was not thorough or accurate enough in describing the context and requirements. I don't think that will work without a lot of unnecessary memory, but maybe I'm wrong.
The user action is actually the successful completion of entering a form, a bill to be more precise. I expect this to happen 100-300 times an hour to give an idea of the frequency. Given a period of time, if they've been at it for that period of time or longer I need to find the number of bills completed in that most recent period of time. Otherwise, I need to use what is available to predict what they will reach in that period of time. In other words, if the time period is an hour I need to figure out how many bills were completed in the last hour, but if they've been going for only five minutes I need to predict what they will have completed in an hour including those last five minutes. Then I need to do the same thing for seven hours, using the last seven hours or less of data.
I guess I'd just have to use a granularity of a minute or less and calculate how many bills over how many minutes and make a prediction on that? I suppose I was hoping for something more precise, but now that I think about it that will probably suffice.
How would you implement it though? Create a "minute" array of size 60 initially, then when reaching the end of that array adding the total for that array to an "hourly" array (keeps track of bills in that hour) and then start over? I guess then you'd just have to add each from the hourly array to the current total and calculate based upon that. At any given time I'd have the number of bills processed in the last x hours and y minutes, which is enough to calculate how much can be completed at that rate in a given hour or seven hour day.
I'll try this tomorrow when I get to work, thank you very much I was needlessly complicating it with timestamps. In fact, this inadvertently (or perhaps purposefully?) solves an issue with not calculating time when a user is at lunch or on break. At least I think it does.

I have a 16GB iPhone 3GS. Tried synching my phone through iTunes (11.0.1 I think... on a 2009 Macbook Pro). Now when I connect to iTunes, it says it does not recognise the content on my phone. Is this because my phone (and laptop) are too old?

Also, when I tried to Restore the settings, an Error Message pops up that says " The iPhone software update server could not be contacted. The requested resource was not found.
I'm trying to free up space on my phone by removing [literally] thousands of old photos which were originally synched to the phone, because I had forgotten to uncheck the photos button when I synched it ages ago.
I have also tried synching it on my 24" iMac (running OSX Snow Leopard). But again, when I try restoring the phone through itunes, it says the file is corrupted. It sggests unplugging the device, and then plugging it in again. I have done this numerous times with no success.
I'm guessing it must be because my phone (and versions of iTunes, and OSX) are all too old.
Please can anybody help.
Cheers,
Dan_nz.

There are multiple reasons that lead to issue. You should read the troubleshooting guide to get the right solution to solve the issue: iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support

I have a MacBook pro that has power issues and will not start but the hardrive is fine. I do not want to lose all of my files so I was wondering if it's possible to transfer my hardrive from a older Macbook pro to a new one if I were to purchase a new one? Also, the software is not updated as the computer hasn't worked for about 2 months.
Also, if it is possible to transfer the hardrive, would my iTunes music transfer as well? It is not saved in the cloud.
Thanks for your help, it is much appreciated.

You computer is probably perfectly repairable, but if you want a new one anyway, it is perfectly possible to transfer the data from the faulty one.
But it would be a mistake to simply put the old HD in the new computer.
These are the steps:
Remove Hard drive from faulty computer. (very easy on Unibody MBPs, do-able but not so easy on older MBPs)
Put it in a cheap enclosure
Connect it the new computer
Boot up new computer.
If the new computer has never been run before the Setup Assistant will ask if you want to import your apps, data, settings etc from either another mac, another HD connected to the Mac or a Time Machine back up.
Obviously chose the second option (another HD connected to this Mac) and follow prompts.
If the new computer has already been run (so Setup Assistant doesn't run when you boot it up), you will need to use Migration Assistant...or run the installer again so that Setup Assistant runs again.

Within the last hour, I noticed that my older MacBook Pro, while I was playing it in iTunes, lost contrast on the screen. I am sorry, but I did not take exact notes on this event. Around the same time, I did do a back up, uploaded software, etc.
