My cinema display won't work over a display port booster and extra long cable.
Hi,
I have a Mac Pro (mid 2010) and an Apple Cinema Display 27". I also have two other DVI monitors. Recently I got a few extenders, so that I can have the computer in a different room to the monitors. Everything works perfectly except the Cinema Display. My system recognises that the cinema display is connected (as it shows as a display in preferences), but the screen is black.
The series of connections from computer to screen is: mini display port to display port adaptor, short display port cable, gefen display port booster, extra long display port cable, display port (female to female) coupler, display port to mini display port.
Please let me know if you have any ideas what the problem may be.
Thank you!
Per your advice to taking out the longest cable, I ran a couple of tests at different stages of the connection. Over a short conversion to displayport and back to mini display port, the monitor connected no problem. It was only when I introduced the "Display Port Booster" that I lost signal, over the short connection.
I think the unit might be faulty and this is the problem. I sent it back to the company that sold it to me and they're running tests now. Hopefully they will be able to fix it.

Flash player won't work or download. It says it no longer supports power pcs. I am running 10.5.8 on my ibook G4. Seem to have tried everything. i.e. chrome, firebird, archived flash players, etc. All not supported. Any insight??? It started when I tried to upgrade current flash player and it said I needed to uninstall current version, which I did, and then it wouldn't download the current one giving me the not supported story! Please help!!!!!!
Hi Andy, that is correct, they don't support PPC Macs anymore.
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb2.adobe.com/cps/865/cpsid_86551.html#prob1=uninst,os=m10.6,
Download this if you haven't...
http://fpdownload.macromedia.com/get/flashplayer/installers/archive/fp10.1.102.6 4_and_9.0.289.0archive.zip
Once downloaded if it doesn't unzip automatically the double click on that file.
Look for the fp10.1.102.64_and_9.0.289.0archive folder, open it, look for the Flash Player 10.1.102.64 folder & open and look for 101r10264 folder & open it, double click on the flashplayer101r102_64_ubmac.dmg file, choose the Install Adobe Flash Player file to install... they don't make it easy!

How can I copy my music files to my iPAD. The CDs are currently stored in folders on my PC. Note: Synching via iCLOUD won't work because I have VISTA OS and I need at least Windows 7 or 8.
Hi ladextr,
Thanks for using Apple Support Communities. To sync your music to your iPad, first put your music in iTunes as described here:
Adding music and other content to iTunes
http://support.apple.com/kb/ht1473
Adding content on your computer to iTunes
iTunes helps you add digital audio and video files on your computer directly to your iTunes library. You can add audio files that are in AAC, MP3, WAV, AIFF, Apple Lossless, or Audible.com (.aa) format. If you have unprotected WMA content, iTunes for Windows can convert these files to one of these formats. You can also add video content in QuickTime or MPEG-4 format to iTunes. To learn how to add these files to iTunes follow the steps below.
Open iTunes
From the File menu, choose one of the following choices:
MacAdd to Library
Windows
Add File to Library
Add Folder to Library
Navigate to and select the file or folder that you want to add
If iTunes is set to "Copy files to the iTunes Music folder when adding to library," iTunes will copy all content that is added to the iTunes library to the iTunes Music folder. To adjust this setting or change the location of this folder, go to the Advanced tab in iTunes Preferences.
Once that's done, you can sync the music to your iPad by following this article:
iTunes 11 for Windows: Set up syncing for iPod, iPhone, or iPad

So just like last time I tried to update my iPhone software...MY PHONE IS FROZEN. Displaying iTunes icon and a USB cable I pressed the Power button and the menu botton together until the apple icon appeared held them down for 10 secs & NOTHING Now what? Do I just wait for the battery to run out?
Hi Careesa,
Your iPhone is in recovery mode-- you need to connect it to your computer and, most likely, iTunes will ask you to restore it. If you recently backed up this shouldn't be too much of a problem. -
Ichat is not working. tried using port 443 and still does not work
ichat not working. tried using port 443 and i stay on for about 45 seconds then it disconnects. Can you help?
HI,
Can you tell me the make and model of your routing device.
The 10 Second error message is caused by a break in the connection.
This could be the Wifi being dropped (if you are using WiFi) due to interference from other nearby routers.
It can be dues to setting or features of the router and if the experience has changed that could be due to a speed increase in your internet service.
If you are using Ethernet and having this issue it is much more likely to be a setting/feature issue.
Examples.
Netgears. These have a separate WAN set up page that lists either DoS or SPI as one of the things that can be Enabled or Disabled.
Linksys. If your model has a Security tab and this has Firewall then DoS and SPI are port of this.
Netopia devices Tend to have a 4 level Firewall which DoS and SPI are part of the two highest settings.
DoS = Denial Of Service and is a Threshold based "Protection" Feature.
it judges whether too much data is being sent to you (it was designed originally to stop people overloading Web Servers (many people, many refreshes).
iChat can outstrip the setting with most Internet Connections in most part of the world. (In fact iChat can send more data than most Video Streaming sites)
One thing you can do that may get around this is to reduce the Bandwidth used in iChat (iChat Menu > Preferences > Video Section > Bandwidth Limit drop down)
Try 500kbps

Gradient Mesh Tool won't work over a standard gradient
How can I get the Mesh Tool to work over a gradient? If I place an RGB image and create a gradient mesh over it I can select each individual point and then use the color picker to pick a color underneath by clicking the placed image. However, if I create a gradient mesh over a standard gradient I can not pick up the color in the standard gradient that is below. What the color picker does is pick up the entire gradient. It doesn't put any color into the individual points of the gradient mesh.
Thanks guys for the answers. I appreciate it. I did determine that I could rasterize the gradient so it would be treated like a placed image. That breaks the vector attributes but it does work.
I swear that I tried all the modifier keys (ctrl, shift, alt, ctrl+shift, etc.) but I guess not. I was crunching out a job at 4AM and I guess I missed something. I do usually try all of them before I look for other options. I thought that I might have overlooked a switch or preference. But I couldn't find one. Using "shift" does in fact work well. Thanks for redirecting me back to the most simple solution.
It always amazes me how the mind works, although frustratingly. I bet that I tried "shift" and maybe missed the key (I don't look at the keyboard most of the time as I do it by feel) or I didn't push it all the way down. Whatever the malfunction, once my brain thought that I'd tried the "shift" key I never went back and tried it again. It just goes to show you, you need to try each potential solution several times before moving on.
Thanks for the answers. It has me rolling again and having a great time exploring the world of the gradient mesh. -
Three new Macs ... iChat video won't work over WAN
Hi,
We just bought two iMacs and a MBP, all running Leopard. We can iChat when in the same house on the same wireless network, but when we go back to our homes, it doesn't work. Below is the error. We can use Skype video no problem. iChat text works works fine. We've reinstalled iChat, matched or unmatched the font, reduced the bandwidth in iChat, etc. We haven't altered the router settings. Hope someone has a suggestion. Thanks.

Content-Length: 0We do agree that there is a good possibility that the log that was posted is from a Bonjour (ie; local) iChat session.
The 192.168.1.x subnet is part of an address block assigned by the authorized addressing body as Private addresses. They should not be advertised on the public Internet and are NOT routeable across the public Internet. Also, when you mention other logs in these discussions, aren't most of the logs and/or discussions here of scenarios when something does not work ?? Can you refer to a known, good, working iChat video-chat log going across a WAN/Internet (not a local LAN or Bonjour) that shows both the To: and From: IP addresses as 192.168.x.x ? The bottom line is if the actual transmitted SIP:invite packet (not some possibly inaccurate Log message) has a 192.168.1.x address as the destination IP, I do not think it will work. Some of the Logs that iChat provides do some processing or filtering such that I am not sure that it is an actual packet capture/decode.
Again, I am certainly open to learning something, but my understanding is if the packet put onto the wire is destined to be routed across the Internet to another user behind a NAT router, a destination IP (or a To: address) of 192.168.1.x will not work.
The process when going across the Internet , as I understand, is very simple;
- login to OSCAR server on "typical" port 5190
- after OSCAR authentication, login to BOS server, get Buddy List, "self info" such as publicly visible IP address, etc...
- initiate Chat request to a Buddy (example userB)
- send Chat request message to BOS server requesting Chat with userB, still on port 5190. Chat request includes data indicating the userA public IP address and public SIP signaling port number. UserA may have obtained this info via communication with the SNATMAP server, where it sends a message fom a private (ie; 192.168.x.x.) source IP address and private source port number to the SNATMAP server, which then sends back a message telling the userA what IP and Port were actually received...in other words, the publicly visible IP and port that the NAT router translated the private ones to. Typically the private ones would be 5060, 16384-16403..but others are possible.
- BOS server relays Chat request to userB, including "rendez vous" data which has userA IP address and SIP signalling port number.
- UserB may send back a message via the BOS server to the userA indicating its public IP and public SIP signaling port number as well.
- One end can now initiate the SIP:invite message with the Destination IP and port# equal to the PUBLIC IP/port that was sent in the Chat request
- The public port# should be open since the userA/B would have sent messages to the SNATMAP server so as the "open" the port on the NAT router.
- The SIP:invite message will have an SDP section that will indicate which port numbers to use for Audio, Video, Audio Contol, ad Video Control. Again, these should be the "publicly" visible (ie; Internet side of the NAT router) ports as learned via SNATMAP (or other methods such as UPnP..). The internal values for these ports are typically 16384,16385,16386,16387 for Tiger and 16402 for Leopard. The publicly visible values depend on the specific NAT router and how it translates internal address/port numbers.
- Once each end receives the SIP:invite and SIP:ok with the SDP session parameters, they will negotiate audio, video, etc..parameters..and if they agree, it should work.
The key n all of this is to get the correct SIP signaling port number, and then the correct SDP session attributes which include the A/V and A/V control (ie; RTP, RTCP) port numbers. And, finally these must be public, Internet routeable addresses in order to work across the Internet. -
I have a LaCie RAID Quadra hard drive (two disks in a case set to a redundant array) which for all intents and purporses appears as a normal hard drive to my mac.
When connected directly via FW800 to my Macbook Pro (2011, with thunderbolt port), it works perfectly.
For the sake of convenience, and since I am using it only at home as my Time Machine drive, I connected it to the FW800 port on my Thunderbolt Cinema Display. The display works perfectly in every way up until now.
When connected, the drive works great. However, when I put the machine to sleep, upon awakening it, I receive the "Disk improperly ejected" error immediately upon the screen coming up.
The drive is set to Auto mode which has always worked fine in the past; putting the drive to sleep when the computer is asleep, etc.
So, I only receive the disk ejected error when it's plugged into the Cinema Display; not when directly plugged into the MBP.
I have the 1.1 firmware update applied to the monitor.
Any ideas? I appreciate it.{quote}
My desktop has two FireWire ports. In the first one I had my webcam plugged in. In the second one, the External Hard Drive. I unplugged the camera and used the first port for my External HDrive and now it works! So it seems the problem is a hardware problem with the port.
I'd check to see if the problem returns when you plug the camera back into the second port, or if the drive works in the original port when the camera is not connected.
Edit: Maybe you unplugged the problem, when you unplugged the camera?

So I Have moved over all my purchases and everything to an external hardrive. I did everything right and my itunes story works perfectly fine. However one of my podcasts (yugioh the abridged series) won't copy over along to the ipod saying its file type is not supported by the ipod. It only does this with the first 8 episodes (if you find it you will see them) one of which (the bbt movie) worked perfectly fine on my ipod before but now for some reason it won't. It also won't work on a few of the tv shows that are in hd and one music album that had american boy in it. I'm wondering what I can do to solve this problem. My itunes and my computer (windows vista operating system) is up to date and I have an ipod classic with plenty of room what should I do.
This doesn't work. The iOS4 upgrade has wiped out synchronization to Outlook to the phone and back. There are many threads on this here, and Apple has yet to address this issue.

Mac pro cinema display cuts out and can't access Mac with screen sharing
Hi
A weird thing has started happening to my Mac Pro today. After using it for a few minutes the cinema display it is attached to on the Mac Pro just goes black. The Mac Pro is clearly still on - the light is on and i can hear the fans. The Mac Pro shows up on my local network and i can connect to it and access files from my Macbook, but screen sharing doesn't work (i just get the message 'contacting mac pro' and nothing else) and i can't connect to shared iTunes library either, which makes me think it is not just a display issue. I cannot wake the computer with the mouse or keyboard, which makes me think it isn't just a sleep issue. All i can do is physically turn the Mac Pro off, start it up and it will start up successfully and then work for a few more minutes before i get the same problem. I have reset the PRAM and SMC and still have the same problems. Can anyone suggest anything else i can try?
I should mention that i have another problem with the Mac Pro in that it has been spontaneously waking up from sleep and starting up from shutdown, and i still haven't resolved this. I don't know if it is connected to the above issue.
thanks
nickI have experienced almost the exact same thing with my new 2008 Mac Pro and my 30" Apple display. It has happened to me twice in the last few weeks. The first time I chalked it up to a fluke, but now that it's happened again I searched the forums. In both cases I've had music playing in iTunes which continues playing, goes on to the next track, and so on. So the machine has not crashed in full. I too can connect to the files via another computer on the network, but cannot share the screen.
I have not had the sleep issues you have had.
I'll look at the link you provided in your next post to see where that gets me, but I wanted to let you know you were not alone on this one.
