These 6-pin cords are readily available for not much money, but the searches are toturous, often involving references to the G5. Like this one from Amazon (US):

Cinema Display 24" won't work with Mac Mini 3.1

I recently purchased a refurbished Apple LED Cinema Display 24" from a buddy. I'm pairing it with my used Mac Mini 3.1 (2009?). The display port mini connections seem to match. The USB is plugged in. The only cable unused is the "macbook power" plug, from the display. I know the display and CPU both work fine independently. Cinema display seems to power the USB and "Macbook power". I just can't get any life out of the display. These 2 devices should work together right? Is there a sceret power-button that I don't know about?

The video cards that ship with the current Pro have one Display Port and one mini DVI port.
There is an adapter to connect a DVI monitor to a Display Port connection. There is no such thing as an adaptor that will let you connect a Display Port equipped monitor to a mini DVI port on the graphics card.
Final Cut Pro uses dual monitors connected to the same graphics card. Using a twin graphics card setup causes problems with FX Plug FCP plugins, which can cause FCP to fail to launch.
The solution is to find a Graphics card with dual Display Port connectors, (if one even exists) or replace it with a grahics card that uses dual DVI ports, such as the ATI 3870 HD. Of course, the latter means that you cannot connect two 24" Apple Cinema Displays.

Old Cinema Display 22" won't work with DVI-ADC adapter & Mac Pro

So, I want to use my old 22" ADC Cinema Display with my new Mac Pro with the Radeon x1900 card.
And I was told to buy the DVI to ADC adapter, which I did.
But it doesn't work! The adapter powers up my monitor, and it shows up in the Display settings of system prefs, but the monitor remains DARK.
Anyone hear of this happening? I spent an hour with Apple Care phone support. They have no idea what to do.
Is the 22" (model #M8149) just not compatible with this adapter? I'd hate to have to buy a whole new monitor!

Yes, I tried re-setting the PRAM as well. Didn't work.
I've gone into the Monitor display settings and clicked "Detect Displays"...I've changed the Hz on the VGA monitor that I have plugged in simultaneously (a Gateway FPD1510). Not working.
As I mentioned, the computer does detect the monitor...it shows up in the Display Arrangement window and I can change its resolution, etc.
And the power light is on.
It's just that the screen in black.
Is this monitor just incompatible with this adapter?
Sounds like someone else is having this issue too, right?

I have a late 2010 MB Air (mini display port) and a new 2013 iMac (thunderbolt) which I would love to use as an external display. I suspect that target display mode won't work.Any ideas for how to achieve this?

According to the TDM support page, this isn't possible. I tried it with a Mnidisplay port to minidisplay port cable without success. Its a shame that thunderbolt doesn't appear to be backwards compable as I could have achieved this with an older iMac.
Cheers

You are correct....it will not work. Please carefully read Apple's Target Display Mode: Frequently Asked Questions (FAQ)

ATI HD 5770 Display port won't work

Hi, I'm running Mac Pro mid-2010 on OS10.9.5 with 2-monitor setup. Recently both the display ports went dead. The DVI port works fine. I tried to switch monitors but still not working. The Mac preference can only show 1 port and 1 monitor. Is it the end of my HD 5770 card? Please help.

Screen saver + Energy Saver (Computer Sleep + Display Sleep) won't work since Mavericks

Howdy,
Sorry to bother you.
My computer: iMac (21.5-inch Mid 2011), Mac OS X (10.7.3)
It took me some time to upgrade to Mavericks, but I did it eventually.
After having some problems with Spotlight (which was infinite looping indexing... and I just had to turn if off from Terminal), I realized I was encountering another big problem to me since the installation of Mavericks.
In System Preferences:
- 'Desktop and Screen Saver > Screen Saver' : it is set to 1 minute;
- 'Energy Saver > Computer Sleep' : it is set to 10 minutes;
- 'Energy Saver > Display Sleep' : it is set to 5 minutes;
- 'Energy Saver > Put hard disks to sleep when possible' : it is checked.
- 'Energy Saver > Wake for network access' : it was checked. I unchecked it. Nothing changes.
- 'Energy Saver > Start up automatically after a power failure' : it is unchecked.
- 'Energy Saver > Allow power button to put computer to sleep' : this option is absent from my System Preferences > Energy Saver, but I would like it.
So, before Mavericks, everything was working great.
Now, after 1 minute, or after 5 minutes, or after 10 minutes: it's all the same. Nothing is sleepy. Nothing is energy saving.
I did not change anything in my computer since I've updated to Mavericks. However, I changed Wi-Fi. Since it was the only new change, I've "played" with 'Energy Saver > Wake for network access'. When I opened my System Preferences, it was checked. I unchecked it. It did not change anything. I'm not sure what it's used for.
I would appreciate any advice to make it work as it used to.
Thanks for your time reading and typing your answer,
Have a good day,
Regards,

- 'Energy Saver > Allow power button to put computer to sleep' : this option is absent from my System Preferences > Energy Saver, but I would like it.
Built into the Software now.
Do a backup.
Quit the application.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.
You might try Spotlight again. That is how the App Store knows what is installed.

New Mac Pro Won't Work With Old Studio Display

Hi,
Just got a new Mac Pro Desktop 8-core only to find out my old Apple Studio Display 17" won't work without a $100 adapter. We're thinking of just buying a new monitor instead. My question is will other brands now work direclty with the new Macs - or would they also need adapters? Is a DVI port the same as a DVI-D port?
Thanks for any info...

Thanks so much for the response, Malcolm, I really appreciate it! My old monitor is an LCD, but what we decided to do is since the adapter we found (and HAD to get from Apple directly) was going to cost $99!! We went and bought a brand new Dell monitor instead for $238 - it's fully compatible with the new Mac, and it's 23" (my old one was a 17") - so all's good!
Thanks again,
Jacki

Why Apple Thunderbolt Display won't work on BootCamp Win7 64-bit while being plugged to MBA?

Hello,
I have MBA (latest) & installed win7 64-bit in BootCamp, I do also have Apple Thunderbolt 27" Display.
When I disconnect the ATD and re-connect it in Mac OS X, it works fine like a charm, but when I disconnect then re-connect in BootCamp, it doesn't work at all whatsoever, in fact, I have to restart my MBA (while thunderbolt is connected) to make it work in BC, this is the only way to make it work.
So, my question is; If I disconnected ATD in BootCamp then re-connected it, why it won't work?
I've googled everywhere about this issue, but no luck.
Any idea?

to calculate how much video ram is needed one
take
the vertical number of pixels and * with horisontal number of pixels and * with 32bit colour which is 4 bytes
so if it's the 13" macbook air
1440 * 900 * 4 = 5.184MB for main display
+
2560 *1440 *4 = 14.75MB for second display
sounds like the intel hd 5000 would have that as dedicated memory even if the windows driver did not allow to use shared system mem as extra
could be a problem with the driver for windows
maybe a person who ran a setup like yours would have more to contribute with
my setup is an imac 21" with amd video card and a 24" dvi dell monitor and that works fine in windows so it's a different animal altogether

Help please. Extended display won't work on MBP and AOC 20" 1600 x 900 60HZ monitor. Mirror display does. I've a mini dvd to vga converter cable. Should this work?

I have the same mini display port adapter and Belkin DVI-HDMI cable (but a Panasonic 42" Plasma HDTV) so just set this up on it to see if I could duplicate your problem, unfortunately for you (but good for me) I can't.
I connected the adapter+HDMI cable before switching the HDTV on and then powered up the MBP. It (the HDTV) came up with my background right away (it's set at Mirror not extended Desktop) and when I run System Preferences/Displays get the following. Sorry but all I can confirm is that adapter+cable combination should work ...
Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys?

Cinema Display and MacBook Pro - Power Button won't work

I have been using a 20" Apple Cinema Display (plastic model) with a 17" Powerbook and never had a problem. Recently I acquired a 15" MacBook Pro and it's like the power button on the display has no use at all. The only way to turn on the computer is opening the computer lid, turning it on and then closing it. The display also won't shutdown the computer, although the power button light reacts to the touch. The funny thing is that the display settings button work fine. Does anyone has a clue?

Malcolm, thank you for the answer! But I still don't understand why my new MacBook Pro, having exactly the same connector as my older Powerbook had, won't behave the same way? I'm still using the same DVI to ADC adapter, I'm wondering if the new Macbooks maybe have some PIN assignment disabled on its DVI connector. And anyway, shouldn't the power button be able to at least shut down the computer, as long as pressing it would just open the shut down dialog box?

HT201364 texmate and git 1.8.4.2 won't work on OS X Mavericks. I've downloaded them repeatedly and the following errors display "Textmate is damaged and can't be opened" and Git states "can't be opened because it's from an unidentified developer". Please

MedlockDustin,
for TextMate, you’ll need to download TextMate 2.0 alpha, since earlier versions of TextMate aren’t supported on Mavericks. The file will be named “nightly”; save it to your desktop. Once the “nightly” file has finished downloading, rename it to “TextMate.app.tar.bz2” — that will give it the “BZ” icon on your desktop. Once it’s been renamed, you can double-click on it, and TextMate.app will appear on your desktop. Use your administrative login to move TextMate.app to your Applications folder.
Regarding the “unidentified developer” message displayed by trying to open git 1.8.4.2, please refer to this Apple page for the workaround.

Hey, I have an unopened iPad mini that I won at work and I'm wondering if there's an upgrade option where I can exchange this for an iPad mini with retina display? Thanks

Take it to an Apple store and ask. All they can do is say no. They may ask for a purchase receipt to make sure it's not stolen.

Hi I'm thinking of buying Adobe After Effects CC for my MacBook Pro. But I am worried it won't work. Here are my specs 2.4 GHz Intel Core i5, 4 GB Ram, 1333 MHz DDR3,13-inch (1280 x 800) are my displays and I'm up to date with latest software.

Hi I'm thinking of buying Adobe After Effects CC for my MacBook Pro. But I am worried it won't work.

I need to know if this will work on this Mac and or if there is any other After Effects that will work.

The display would not. However, your model does not have a discrete GPU, and the integrated (Intel 3000) would not meet CS6's requirements (any CS6 software) alone.
However:
Standard VRAM:
384 MB
Maximum VRAM:
512 MB*
Details:
Apple reports that "memory available to Mac OS X may vary depending on graphics needs. Minimum graphics memory usage is 384 MB". *If upgraded to 8 GB of RAM (or more), 512 MB will be reserved for video function.
In other words, you would need to upgrade your RAM to 8 GB. The VRAM (video ram) of the processor can exceed its specifications if you upgrade your memory to 8 GB. In order to run the software, you would have to upgrade your RAM first:
