View 1 RepliesI started up iTunes, checked my email, and looked up to see the top half of my display drop about 15 shades darker than the bottom half! I called Apple Care who told me they had never heard of something like this before and advised me to call the nearest Apple Store. I did, and like Apple Care, they had never heard of this happening.

I was trying to install windows on my pro, and i had bootcamp chop the hard disk in half, but then my disk drive didnt read the cd so i had to download and install some file. and after i restarted i could no longer access the windows side, it just disappeared.....plus i cannot reset my hard disk, cant erase it, and i cant reinstall OS X because there is no memory left..
At the beginning of last year I bought a 3.2GHz 27" iMac. About a month ago I noticed that, within about 5 minutes of starting my computer back up from sleep the left half of the screen would flick and become darker than the lower half (about 4 clicks of the light button lower). Sometimes the screen will flick to become even darker than this (but usually it returns to the 4 clicks darker after a short while), and sometimes it returns to normal only to go darker again.

iMac (27-inch Mid 2010), Mac OS X (10.7.3)
I have a MacBook Pro with the 9600gt in it. Since updating to 10.6.4 this morning 2 times while playing java games i've had the bottom half of my screen go black and most of the top half flicker. I've had to hold in the power button and reset both times. The second time I closed the screen and reopened it, the screen was black but no mouse and nothing moved.
Any advice? Would this be something to do with my graphics card or possibly some error in 10.6.4?Edit:: This is software related to 10.6.4 update and only happens when I open up a java game in a browser.
Third party testing has confirmed that Apple's new 27" iMac can only be used as an external display for devices designed to provide DisplayPort video. It will not work with any equipment that only supports VGA, DVI, or HDMI output.
In a follow-up to its teardown of the 27" iMac last week, iFixit said it revisited the new hardware to see if it could display high-definition video from a non-DisplayPort external source.
The results of the testing indicate that Apple's stated specifications for the iMac were correct; while video input worked as expected with a 13" MacBook Pro equipped with Mini DisplayPort, all attempts to use a physical adapter dongle to supply alternative video signals to the new 27" iMac failed.
"The iMac will not act as a second (or primary) display using the Mini DisplayPort to DVI adapter that Apple sells," the group's website stated. "We tried it on a PS3 Slim, as well as a MacBook and MacBook Pro. It looks like we'll have to wait for a special adapter from Apple or a third party."
A one way street
According to Apple's stated specifications however, the 27" iMac's video input feature will only ever work with DisplayPort devices, and no physical adapter will change that fact.
Apple has frequently used converter dongles on its notebooks in order to support multiple types of video output signaling via the same port. For example, previous notebook models provided Mini-DVI ports proprietary to Apple which could deliver both VGA and DVI outputs using the appropriate connector. These ports provided multiple signaling types over the same physical pins.
Apple's modern machines similarly all supply a Mini DisplayPort connector (originally designed by Apple but now part of the official DisplayPort specification); using the right connector, users can extract and output any video signal type supported by the computer, including VGA, DVI, HDMI, and DisplayPort.
VGA is analog video; DVI and HDMI are both digital, electrically compatible, serial video data formats that only differ in their physical connectors; DisplayPort is an entirely new format that uses a packet signaling format.
The iMac's Mini DisplayPort supports output of all three, but can only input and display DisplayPort video. Unlike moving from DVI to HDMI, converting a DVI signal to DisplayPort requires more than a cheap physical dongle; it would necessitate a relatively expensive converter box to process the signal into a completely new format and possibly also a scaler to match the output device to the 27" iMac's enormous resolution of 2560x1440.
This prevents the new iMac from serving as an HDTV-style output source for older DVI-based computers or HDMI-output devices such as the Playstation 3, Xbox 360, Apple TV, or standard DVD and Blu-Ray players. Future devices that support the DisplayPort standard will work, of course.
Why no DVI or HDMI input is supported
The 27" iMac's inability to input DVI video is rooted in the fact that the DisplayPort specification is uniquely designed to work as both an internal (video card to built-in display) and external (PC to monitor) video signaling system.
Non-DisplayPort systems typically use LVDS for internal video cabling and DVI for external video connectors. No Apple computers supply any sort of internal DVI input to support driving their built-in LCD via the DVI port using an external computer.
Apple's existing MacBooks, Mac mini, Mac Pro, and the smaller new 21.5" iMac model do not support video input at all. The company's 24" LED Cinema Display is the only other device that currently supports (and only supports) DisplayPort input. The 30" Cinema Display HD only supports DVI input, but not DisplayPort.

Allright, I have a 24" iMac. 3.06 Core Duo 2 4GB RAM etc etc.
Just now, as I was innocently talking to a friend using iChat, the top of my screen flickered once or twice and then went dark. I am typing on it now, so it is not unreadable, it just looks like the back lighting has gone off on the top half. The middle is relatively light (bleedover from bottom back light?). I have tried playing with the hinge to no avail. After I reset the computer, cleared pram-nothing. Zippo. I got the top to stay lit for about a half second after reset, but it then flicked off again. Do I need to load up my iMac and drag my ass to the Apple Store (it really is quite a task to drive there)?Here is a horrible cell phone picture (and no, the screen IS dark, that's not a shadow.):
I have a WDS local network at my house. I use a Airport Extreme in my main part of the house and a Airport Express for my back part of the house i.e. the backyard. Now every two weeks or so my internet speed through my Airport Express slows down about half the speed but when I am connected trough the Airport Extreme my speed is normal. I know this because I test my connection very often. Now when I want the Airport Express to get back up to speed I have to unplug, and plug it back in. Then after awhile it starts to slow down again in a time period of two weeks or so.

My eyes feel like there bleeding from hours of starring at screen and reading text to no avail. I am of limited funds so a send away for repairs is probably going to be beyond my means.

I have a Brother 5280DW printer which is supposed to offer duplex printing. I have an IMAC running the latest Leopard, but there seems to be no option anywhere I can find to choose duplex (double sided) printing...
anyone have any ideas or guidance?
I would like to print a copy of my Nikon D90 instruction manual which is saved as a PDF.
I'm trying to figure out how I can print a booklet using the least amount of paper. My logic was to have two pages to one piece of paper. My printer cannot do automatic duplex so I would have to print using odds and then evens.
Therein lies my problem � if I am printing odds it'll turn out that Page 1 & 3 are printed onto one page together.
So how would I go about printing Pages 1&2 and then 5&6 etc and then when I do the manual duplex it would Pages 3&4 and 7&8 etc
I'm not sure if I'm making sense but hope someone can help � it's 300 pages which I could then print on 75 pages.
I have a Brother HL-2170W which allows for manual feed duplex (that's too hard with 300 pages) or using the odds and evens method.
Does anyone have any recommendations for a printer that works well with a mac that can print color and duplex?
View 6 Replies View Relatedhave a new macbook 13" with intel processor running OSX and use HP deskjet 970CSE that allows for automatic duplex printing on multi-page documents. The duplex printing option is unavailable and is greyed out. I have tried to access the function with the standard OSX drivers and after downloading the HP drivers to no avail. I am looking at upgrading my printer to a EPSON WORKFORCE 600 to allow wireless printing throughout the house and wanted to see if you know if the duplex printing will work with that printer also? That printer also allows auto-duplex.
View 2 Replies View RelatedI think it's time for me to go to wireless printing, and I'm tired of printing only single-sided (or trying to manually feed printed paper back in to try to get it two-sided.
Are there affordable laser printers out there that print duplex, have wireless, and are Mac-compatible?
Today, I purchased a Canon Pixma MX350 printer, which is capable of automatic duplex printing. However, when I go to Print in Word, the 'Two-Sided Option' in the 'Layout' menu is greyed-out. Having spent a lot of time Googling and found several similar posts (but not for this exact printer), I understand that this is normal for a Canon printer, but that I should instead have a menu that says 'Duplex Printing & Margin', under which I can select duplex printing. However, I can't find any such menu and can't think of any other way to get duplex printing. The Canon driver I originally had (which comes from the CD provided) was 10.29.0.0. I found a newer one, 10.30.3.0, on the Canon website and installed it, but it didn't fix the problem. I'm running Mac OS X 10.5.8.
Since my main reason for buying this printer was because I need auto duplex printing.
II think it's a Snow Leopard issue, meaning that I don't think there's anything wrong with my printer or its connection. Laserjet p2015dn. Always printed duplex when requested, although I can't say for certain that 10.5.8 worked, since I don't print duplex regularly. After SL, I had only the "Manual Duplex" option, and nothing I could do would return my standard Duplex option. I reinstalled, reset the printer firmware, etc. etc. Every place that there's a duplex option, it's checked. Everything else about the printer is fine -- it sits out on the network and prints happily. I have not made a USB connection to see if that makes a difference.

As with most companies, ours is on a push to go greener. The IP department has decided that one thing that can be done is to encourage the use of duplex printers. We have one, but from the Mac you must go in and specifically select printing on both sides somewhere in the print screen for each app. Is there a way in the setup of the printer to make duplex printing the default?

I recently got the HP C4780 printer free with the rebate deal. It says that it can two-sided print, but the option is grayed out. Any ideas? Everything else seems to work. Anyone else having this issue or have any ideas? My next move is to download drivers from site, but I hope I don't have to reconfigure the printer, so I am holding out for a few.

View 6 Replies View RelatedAfter installing snow leopard on my 2.8 GHz 8-core Mac Pro, I cannot do duplex printing. I have also installed the 10.6.1 update. I presume snow leopard thinks my printer driver is up to date, since I have not received the HP printer driver update to install. I have even downloaded the HP Printer Drivers for Mac OS X v10.6 update from the Apple Support downloads site, but I get the following "error message" prior to the installation completion:
System extension cannot be used
The system extension "/System/Library/Extensions/hpPlugInInit.kext" was installed improperly and cannot be used. Please try reinstalling it or contact the product's vendor for an update.
There was a mention elsewhere of a check box in "print & fax" in system preferences to enable duplex printing. Unfortunately, I cannot find this check box.
I'm looking for a printer with the following:
- Color
- Has automatic two-sided printing
- Works well with OSX
- Small footprint is a plus, but not a dealbreaker
- If it has a scanner that would be nice, but not required
- I don't really care about WiFi printing
I'm going to use the printer mostly to print out reports and long pdf documents. I don't really care for photo printing.
upgraded to snow leopard-now it gives message the "Auto Duplexer" is not installed on my epson Sprx680 combo printer. Got it working fine in "Leopard".
Driver version on printer is V. 8.02. reinstalled combo update for 10.6.1 and still doesn't work. Any ideas out there?
My lab just got a new HP Color LaserJet CP3525 and while everyone else can print double sided (both Linux and OS X), I am utterly unable to. I don't even have the option. This is weird, because I have the correct drivers installed and in the system preferences panel, I have the option for duplex printer checked.
