Power shortage caused by mini-display touching firewire port.

I discovered if you touch the in firewire port with a mini-display adaptor the power cuts and you need to restart the machine.
Has anyone else discovered this happens or is it jsut this one machine?

Well that would create a dead short between the pins on the FW port, as the mini display adapter has a metal outer surround, I would think that it cause an issue with any machine as these pins are not intended to ever touch. BE CAREFUL!

What can I connect to the cinema display´s firewire port?

What do you think of connecting an external hard drive to the cinema display´s firewire port? My other firewire ports on my G5 are already occupied.

The FireWire ports on a Cinema Display can be used with anything that the FireWire ports on a Mac can be used for; they are included because a Mac and external monitor may be set up in a way that prevents the ports on the computer from being easily accessed.

IRONY: 2 Apple Displays & 1 Firewire Port

I find oddly unsettling that my brand new setup (3.2 Mac Pro + 2x 23" Cinema's) has an obvious flaw. Two Displays means I have two USB / FW hubs built in, yet when I run the cables across my desk and down to the Mac Pro, I can plug in the 2 DVI and 2 USB cables, but one of the FireWire cables is left to dangle since there is only 1 FireWire 400 port on the back. To make matters worse, the cable isn't long enough stretch around front (not that I would want to).
Design flaw? Logistic over sight? Laziness? I sure won't return the thing, but wow this seems odd.

Well, actually there are two ways to look at it, none maybe from my angle. There is only ONE bus and you are just splitting (hairs) to daisy-chain devices. At least the 2008 is now linked to a new PCI Express bridge inside so FW800 is better, but all FireWire ports are running on one bus/channel.
Add a PCI Express card, and that may have multiple ports, but only one (extra) bus.
Then you have problems if you end up mixing drives and consumer electronics on the same bus. And, to make matters worse, there are some problems users experience with the built-in USB hub(s) in the ACD, keyboard, etc.
You don't say what you need to attach, whether a powered hub or 2nd controller would help, or whether best served with SATA drive controller.

Dual Display Issues, Mini Display Cable, Firewire, USB, Nothing Works

I am working on a project for my supervisor, the specifics of each machine are listed below to the best of my ability:
Machine 1:
iMac9,1 Intel Core 2 Duo
Version: 10.6.8
Build: 10K549
Machine 2:
iMac10,1 Intel Core 2 Duo
Version: 10.6.8
Build:10K549
I have a iLuv Mini DisplayPort Cable, a 9-Pin to 9-Pin Firewire Cable, a M/M USB Cable and an ethernet cable. What I have been trying to do is link these two computers together so that each can be used as a seperate processor but their screens can be shared. Before anyone tells me this is impossible, these two monitors have in the past been connected together so there was the ability to dual use the computer monitors. I do not remember if I actually had the processing power of both available. When I plug the minidisplay port cable from one computer to the other the screen on Machine 2 will blink black to blue and then go back to an independent screen. The displays tab on neither computer shows two displays and none of the command f2 or f3 prompts are causing either computer to respond. I have tried connecting them with firewire and USB and can only get disk transfer mode from the Firewire. I know these computers used to be able to support being connected to one another and now I have no idea what is going on. I don't personally remember having a minidisplay port cable in the beginning so its possible I am going about this all wrong. I have called Apple Support many times and they suggested an OSX reinstall. I found the reinstallation software for 10.6.3 for a macbook 13 inch and each computer recognized the disc but said that the operating system could not be installed. At this point I have done everything I can think of including running a hardware test through the diagnostic tool at startup and on both computers the test came up with no error codes. Please please help me get these computers working again for my boss!

Both the 9,1 (Early 2009) and 10,1 (Late 2009) iMac's only support Target Disk Mode using FireWire.
see > Target Disk Mode vs. FireWire networking | Macworld
or > Apple Tips Using Target Disk Mode
Adding that if the Late 2009 is a 27" then it supports Mini DisplayPort input for use as a monitor from another Mini DisplayPort Mac.
see > iMac: How to use your iMac as a Target Display Mode display
An Ethernet cable can be used for Networking and File Sharing the two iMac's.
see > Mac Basics: File Sharing
Plus connecting two iMac's together with a USB cable, will do nothing except trip the USB port overloads or something worse.

Do i need a genuine apple mini display to hdmi port?

considering putting the display from my macbook pro (2011) to my tv and i was just wondering if needed a genuine apple mini dispaly to hdmi adaptor or if i could buy a third party one?
cheers

Never had a problem.
I believe you, but that's a sample of one. I and others have had problems and as the adaptor is such a small fraction of overall cost I standardized on the Moshi, from the Apple Store and now have no problems, I use these installations in bars, and there are over 30 of them so for me consistency matters, and the screen/macmini costs way more than the adaptor/cable combo.
Read the many posts on this subject, a search on Moshi will reveal them as it is regularly recommended in this forum.
And as your adaptor works so well, how about identifying it for others?

Mini display is shutting down computer.

I've been using a mini display to HDMI cord for awhile and nothing has been wrong with it until the other day. When I plugged the mini display into the port on my 13 inch MacBook Pro, it just shut down. Does anyone know why?

This isn't a new RAM issue as I haven't installed any. When I re-installed all of the software from the ground up, I did an erase and install, so the whole thing should have been basically wiped before I installed the Mac software.

Do I have a mini display port?

Hello - would anyone be able to confirm if I have a mini display port? I think I only have Thunderbolt but am really not sure, am clearly quite silly!
Would appreciate help. I have an iMac which I bought in Sept 2011 and it uses Mac OS X......but you will already know this. Oh, and it is 21"
Thanks
Pandora

Okay - I have a feeling that the mini display and thunderbolt port are the same??

MBPro w/Mini DisplayPort to Cinema Display w/only USB and Firewire ports?

I've searched the threads for something that will explain what kind of cable I need to use my Cinema Display with my MacBook Pro, and I'm not finding anything. The MacBook Pro has the Mini DisplayPort for video out, and the Cinema Display's only ports are two USB and two FireWire.
All of the video cables I've seen in the online Apple store are either Mini DisplayPort to DVI or Mini DisplayPort to VGA, neither of which would work. Tech support told me that the computer and the display are compatible -- can anyone tell me which cable I need?

I have been using the display for several years, connected to my G4 PPC Mac Pro. Now that I have a new MacBook Pro, I was thinking of getting rid of the tower and simply using the laptop.
The cord coming out of the back of the display is connected to the tower with both the DVI plug and two USB plugs. It didn't occur to me to look on that cord because my understanding was that there was a port on the display itself, and I always think of that cord as simply a power cord.
I understand getting a DVI-to-Mini DisplayPort converter cable, but the Cinema Display is apparently powered by the Mac Pro tower. Would a laptop be able to power the Cinema Display? And would I have to connect both USB plugs to the laptop? That would take up both of the MacBook Pro's USB ports.

Is it possible to use old Apple Flat Panel Display (62 watt power adapter) with MacBookPro 13" Mid-2012 running 10.8.4? Tried mini display to VGA cable

Is it possible to use old Apple Flat Panel Display (62 watt power adapter) with a MacBookPro 13" Mid-2012 laptop? Would like to use larger screen when working at home. I have a mini display port to VGA cable and have tried to hook up the old display but it seems not to work. When I try to activate the screen on the old display-- a window comes up in the MacBookPro and asks me if I want to shut down the computer. What little I have read it that the MacBookPro had Thunderbolt and the old display may not be compatible? Any assistance would be appreciated.

11.09.12 22:16:06,148 ClamXavSentry[286]: I will quarantine infected files
This doesn't have anything to do with your problem, but it will likely cause other issues with your e-mail.
Here's my standard recommendation concerting the use of A-V software to deal with potentially infected messages:
Never use ClamXav (or any other A-V software) to move (quarantine) or delete e-mail. It will corrupt the mailbox index which could cause loss of other e-mail and other issues with functions such as searching. It may also leave the original e-mail on your ISP's e-mail server and will be re-downloaded to your hard drive the next time you check for new mail.
So, if you choose to "Scan e-mail content for malware and phishing" in the General Preferences, make sure you do not elect to either Quarantine or Delete infected files.
When possibly infected e-mail files are found:
Right-click/Control-click on either the infection or file name in the ClamXav window.
Select "Reveal In Finder" from the pop-up menu.
When the window opens, double-click on the file to open the message in your e-mail client application.
Read the message and if you agree that it is junk/spam/phishing then use the e-mail client's delete button to delete it (this is especially important when the word "Heuristics" appears in the infection name).
If you disagree and choose to retain the message, return to ClamXav and choose "Exclude From Future Scans" from the pop-up menu.
If this is a g-mail account and those messages continue to show up after you have deleted them in the above manner, you may need to log in to webmail using your browser, go to the "All Mail" folder, find the message(s) and use the delete button there to permanently delete them from the server.
To fix the corrupted mailbox index(es), highlight each one that was corrupted and choose Rebuild from the appropriate menu.

Will a firewire cable work with a mini display port?

I recently upgraded to a new Macbook Pro and I need to transfer my files from the older macbook pro.
Can I use a thunderbolt cable to transfer files from my 2008 Macbook Pro (using a mini display port) to my new Macbook Pro thunderbolt port? It would be great if this could work. Otherwise, I will have to return this (still unopened) cable for another option.
The older notebook is running SnowLeopard (10.6.8), and the new one is running the most recent version of Mountain Lion (10.8.2).
Any feedback or recommendations would be greatly appreciated!

Thunderbolt was introduced in 2011. So, while the ports looks the same, they are not functionally the same. You'll need to use another interface (firewire, USB) to transfer files between the two computers.
Personally, I'd hold on to that cable though. I never know when a cable's going to come in handy. But that's just my personal preference, not shopping advice :-)

Mini Display to HDMI adapter causing screen to go white/ gray

I recently purchased a mini display to hdmi adapter to hook my macbook pro up to my samsung led tv.
At first it worked great but after a few mins of inactivity both screens would go white or light gray and the macbook was totally unresponsive.
I pressed buttons, moved the mouse and nothing….I had to hard shut off and then restart the macbook to get the screens to come back up. I thought it might have been just a glitch but then it happened 2 more times all within the span of 2-3 hours. (keep in mind this is the first time ive ever used this adapter and have had no prior issues with my macbook)
I have no idea what could cause this type of issue.
Any suggestions or ideas on what could cause this? is it my settings or my computer?
I looked up the manual for my macbook online and my settings match what it says they should be… Im at a loss.
Any suggestions would be greatly appreciated. Thank you.

* my connection is macbook pro - mini display to hdmi adapter - hdmi to hdmi cord - Samsung LED tv.

How can I boot and run my Mac Mini on my 12" PwrBk display using firewire?

How can I boot and run my Mac Mini on my 12" PwrBk display using firewire?

bwhit:
Welcome to Apple Discussions.
No reason why you should not be able to do it using Firewire Target Disk Mode. Here's what you do:
1. With both computers shut down connect both via firewire.
2. Startup the Mini and hold down "T" key immediately after chime.
3. Startup the PB and immediately after chime hold down Option key.
4. Select second HDD icon on the screen and click on the right pointing arrow.
5. Computer will boot from Mini's HDD.
Be sure to shut down PB completely before shutting down Mini.
Please do post back with an update or with further questions or comments.
Cheers
