Hi Leon Ellenport,
It seems I have the same issue with my iMac, and I am thinking about my plan of action. Did you ever fixed this issue? If yes, how?
Thank you very much in advance, and sorry for bothering.

Why does my printer print different colours than are displayed on the screen, in Photoshop Elements 10

My printer has begun to print greens as browns. This only occurs with photographs.
Is there a solution to this.
I have checked and I have the latest drivers and the test sheet colours are fine.

I found another thread finally about this issue which effects many. There is a 3rd party that makes drivers that I installed and cut my "sending to printer" time from 10 minutes per page to instantly!
Google: gutenprint or go direct to the Apple page at:
http://gimp-print.sourceforge.net/MacOSX.php
and download Gutenprint 5.2.8-pre1 and install the drivers (there's an uninstall in case you need to)
Then go to: System Prefs > Print & Fax > Options & Supplies... > Driver > Print Using:
Select the driver that looks most like yours. In my case I have a "HP Lasterjet 1200" and Gutenprint's driver substitute is: "HP LaserJet 1200 - CUPS+Gutenprint v5.2.8-pre1"
After selecting your substitue driver, click OK and click out of the Sytstem Prefs and try printing.
I was stunned at the difference in time. It was immediate as opposed to 10+ minutues per page.
The one thing though.. is when I was using the HP Driver and it took so long, the printer icon was in my dock the whole time and if I clicked it and launched the interface, there was an "Advanced" button and clicking that gave me a bunch of configurations that I'd never seen before being that I never got this into printing before. But from memory there was which language to choose: Language 2 or 3 and then, stuff like cleaning up background and others I can't remember now.
But now that the new driver prints instantly the printer icon is in the doc all of 1 second and so I can't launch it to get to options. I remember experiementing but unfortunately can't tell you all what I tried since I can't picture what all the config options were/are.
So.. I'm not 100% sure if the speed I'm enjoying now is partly because of the Advanced configuration changes I was trying. Sorry...
If someone knows how to get to these Advanced options, please post them in this thread?
Thanks,
S

TouchSmart monitor showing vertical coloured lines

My touchsmart is showing vertical colourful lines when I try to boot the computer. I called HP and they said I need a new computer. Does anyone have a solution to the problem?

Model number would help a grat deal...
The IQ7xx units are prone to a certain kind of failure that looks like this, it is gnerally not something the average person would repair with a 3 generation old PC.

Vertical blue line is displaying on the screen.

In my iphone4 the vertical blue line is displaying on the screen.please provide the solution.
the running ios is 6.1.3.

If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5s. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:

You need to plug the iPad into your computer that has iTunes installed on it, and activate it.

Stuffed my iMac monitor - shows vertical coloured lines

Hello,
I was trying to configure an external monitor and failed. I changed some resolutions and now get lots of bright, vertical, coloured lines as the Mac starts up.
The startup screen is fine, I can access single user mode or open-firmware.
I've reset the pram (which fixed the screen perspective back to normal on startup - but the vertical lines continue to appear.
If anyone has any ideas I would greatly appreciate it.
Thanks
Greg

I'm not sure if removing it would have worked, since it had changed my monitor resolutions elsewhere.
Anyway, Stephane (who wrote the app) told me how to resolve...
Firstly: I had already zapped the PRAM, and NVRAM.
Secondly: I could restart in single user mode (start holding Apple-S). To make the filesystem writeable I mounted it "/sbin/mount -uw /"
These fixed the start up resolution, but still gave me the vertical lines after startup.
Then, Stephane wrote:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The best solution finally would be to delete the custom resolutions
completely from the system preferences.
These custom res are stored in /System/Library/Displays/Overrides.
What exact file it is, is depending on your system: sort all the directories/files by date, the one that was modified recently (yesterday or so) corresponds to your added custom resolutions.
Remove this file, and start again: you'll be back at the starting point.
I hope this helps,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I actually went to that directory, found that file (which was also a directory), opened that directory, sorted it, and rm'd the newest file. All is now well.
Thank you for responding, and to anyone who has been thinking about how to help...

Why does iCal now show just 2 lines of info?

Since updating to Yosemite, my iCal sometimes shows only 2 lines of info even though there's space in the box for more lines. Here's examples:
There's room for the rest of the phone number and more, but instead it gave me dot, dot, dot and nothing below. Sometimes expanding the time slot and then retracting it again resets it like this example:
This time-slot box is even smaller than the one above, yet it currently shows 4 lines of type under the (unnecessary) time stamp. When I first typed it in, originally it just showed 2 lines, but then I grabbed the bottom arrow, pulled down till it was a much longer time slot, then slid back up till it was just 1 hour slot, and all 4 lines appeared. Tried the same thing with the top example, but the next line never appeared. Very wanky. Forces me to double click the event to see the full description in the editing pane, but there's no reason why 3 or 4 lines shouldn't show up in the main iCal display...there's plenty of room. What the?

Go to Gmail (on the web) look in the folder named All Mail, they will be there, delete what you want.

Why does my iMac show 3 shared iMacs?

after updating to yosemite my iMac shows that I have 3 shared iMacs? what does this mean? how do I remove the 2nd and 3rd instance of my iMac?

Known bug. One thing you can try is to go to System Preferences/Sharing and un-check all the boxes.
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Or you can use your Apple ID to register with this site and go the Apple BugReporter. Supposedly you will get an answer if you submit feedback.

Why does my maximised app window appear a different size to the screen resolution?

First: I'm a beginner with windows programming, fumbling my way through visual studio and C# (my background is C with console applications)... sorry if this is a naive question!
Short story: When I create a window of the same size as the screen resolution. My app window is ~20% larger than my device's screen. Why is this happening?
Long story: I'm attempting to develop an application with a fixed size window and absolute positioning of UI elements. The application will only ever run at a fixed resolution, on a single device, borderless/non-resizeable and full-screen. The resolution
of the display on which it will run is 1280x800 (according to the device specs and resolution reported by the windows control panel) . However, when I create a window of this size, it is too large to fit onscreen. In fact, I have to create a window 1024x640
(0.8x screen resolution) for it to perfectly fit the screen. Anyone know why this is happening?
Thanks!

It sounds like you are running in a high-DPI mode but your app is not DPI aware and is getting virtualized. Windows will tell the app it's running at 96 DPI and then embiggen the rendered window so it ends up at the user's requested zoom level.

Writing DPI-Aware Desktop and Win32 Applications

My iMac turns on and about 10 mins later it glitches and freezes and then the screen turns blue/green/white

My iMac turns on fine, but about 10 minutes later I can't use the mouse as the whole thing freezes. Sometimes it continues to move the mouse for a while but then glitches the screen (see first image). After that my screen turns blue/green/white and even purple as a solid colour (second image - changes to a different colour). I'm wondering what the problem is and can I fix it myself?

I have a similar iMac.
1. Be sure you have 4 GB of RAM.
2. Create a new USER wih Admin Rights
3. Don't add anything to the start up sequence.
4. Update all your apps. This is a big problem. Do it.
5. Use Font Book and verify your fonts. Delete any broken fonts.
6. Download and install Applejack. If you have to force a restart, press and hold command s. A black screen will appear. Finally it will say something about Applejack. Type applejack and run #1 and #2. Restart.
Don't run Applejack outside of safe mode. (Command s)
Come back and let us know how it is working.

Why does 1 album show up as multiple listings on my iTunes screen?

I have 1,000 cd's burned to my iTunes. I keep them on a single folder on a WD 3.0 Passport HD. The individual CD "packets'/folders appear on my hard drive as complete albums/CD's, but when I open iTunes on my computer and direct it to read my main folder, 70% of the CD's appear intact as one "group" or "album" or "CD", with the album artwork on the left, while others appear broken up, with 4-5 separate sectors on the main iTunes screen. I have re opened iTunes several times, setting it to read one folder. It takes 1+ hour to read the 200Gb and consistently shows 30% of the CD's broken up with no artwork. Does this make any sense? I can send a screen shot of the iTunes screen, so that "you" can see what I am talking about.
How can I get iTunes to show all 1,000 albums/CD's as complete albums/CD's in the iTunes screen on my computer monitor? Do I need software? The info feature that directs iTunes to move an individual song to ists' album does not seem to work.
Thanks!

You don't need to delete them form iTunes on your computer. Notice the dotted circles next to the songs. That indicates that the songs are essentially in limbo. They may not be on your iPad or they might appear in the Music app but will not play.
Sometimes unsyncing those songs will totally remove those ghost traces of the music nd sometimes, you have to restore the iPad to get rid of those traces of the songs.
If you Google "grey dotted circles next to songs in iTunes" you will find a plethora of articles that talk about this.

Why does my iMac have to make such a loud noise when I turn it on?

Is there any way to turn my iMac on in a silent way?
Not that it bothers me but sometimes there are other people in the same room trying to sleep.

Welcome to the Apple Discussions for iMac Intels.
You can install this Preference Pane and control the volume of your startup chime from the System Preferences.
Arcana Startup Sound Preference Pane
StartupSound.prefPane is the software which controls the volume of the startup sound of your Macintosh computer. StartupSound.prefPane mutes the startup sound without changing the output volume setting. And StartupSound.prefPane limits the startup volume so that it may not become loud even if you make the output volume louder. To set up the startup volume, you select the "Startup Sound" pane added to the "System Preferences."

I need help!!! My iPod touch is messed up I charge it but then when I go to turn it on it shows the apple then a loading circle then the screen turns white and says it isn't charged is there anyway I myself could fix it?

Plz help

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
