Connecting imac to macbook. "No devices detected"

I'm attempting to share screens betwee my MacBook and my iMac. I'm using a 18Pin DIGITAL SINGLE LINK DVI-I CABLE to conect them. Both devices are reading "No devices detected". Any suggestions for my next step?

My 2010 iMac (pre-ThunderBolt with Mini-dispaly) connects nicely to my ThunderBolt=equipped MacBook Pro with a standard Mini DisplayPort cable. ThunderBolt connections have the same form factor and pins as mini-displayport.

Can i connect imac and macbook by usb?

can i connect imac and macbook pro by using USB clable? i just want pass my files and music from macbook to imac.
thank you

You can't connect both computers by USB. The easiest way is to connect them using a FireWire cable (if your iMac and your MacBook Pro have got FireWire ports), and put your MacBook in target disk mode (start your MacBook holding the T key).
Doing this, the iMac will detect the MacBook's hard disk as an external disk, so you can easily access to your files from Finder and copy the data you want to the iMac's hard disk

Connecting iMac and MacBook Pro using a non-Apple wireless router

I use a Belkin wireless router. Is there any way for me to connect iMac and MacBook Pro using the router to share files? I think I read somewhere that I need AirPort Extreme for this, but I'm not sure. Thank you.

Great resource from Dennis...file sharing, I.e. networking, is a function of the operating system settings and not the brand of router. Using Mac OS X 10.6 on both machines makes it really seamless. Following Dennis's kb article should make the two almost act like one machine.

Connect iMac to Macbook Pro

I want to connect my iMac to my Macbook Pro to transfer some large movie files.
I want to connect using a wired connection, what is the best way forward please?
Thanks

You can either do it over your home network by ethernet or wifi, or by firewire. Firewire will undoubtedly be fastest and therefore favourite for large files.
Connect the two with a firewire cable, go to System Preferences > Network and highlight "firewire" in the left pane. The little light next to it should change to green. Do this for both Macs.
Now go to > Sharing and enable file sharing on both computers.
The Macs should now be visible in the Finder window sidebar under "shared"
From one of the Macs (doesn't matter which) click on the other Mac's name in the sidebar. You'll be shown only the public folder to begin with, but select "Connect as" and enter the short name of the account you're transfering to or from. Log in with that account's password. You should now have a choice of the home folder or Macintosh HD for the remote Mac.
Easiest way from here is to open two finder windows in column view; navigate one to the place you're copying files from, and the other to the destination folder on the other Mac, then just drag the files across.
Go and make the coffee.
Note that this will copy the files over. If you're doing this to free up space on one machine, delete the originals and empty the trash after you've tried the copies in their new location and are sure they're working fine.

Connecting iMac to Macbook and using the camera

I currently have a macbook pro connected to my iMac. Everything works fine except video programs like Skype and Facetime. Whenever I want to use them, I have to open the macbook, and can't use the iMac camera directly. Any suggestions?

correction, through a thunderbolt. I'm, new to this, sorry if I'm a little slow. I'm troubleshooting for a family member, and was just told some new information. So it's a monitor, not an iMac. Not an iMac, simply a monitor. Does that help?

Connecting iMac to Macbook Air

Cannot connect iMac to MacBook using Airport

I have a MacBook and an iMac. Until recently I have been able to share files both ways. Now I can see my MacBook in finder on my iMac, but if I try to connect, I get a message saying "failed to connect". I can access the iMac from the MacBook OK. Hope there is someone out there who can help me.

OK.... the is really baffling me...
Here's my setup:
Airport Extreme - constant PPPoe connection to ISP - running 80211n only
iMac conneting to Airport Extreme via ethernet
Macbook connecting to Airport Extreme via 80211n
Airport Express connected to Extreme via ethernet
Macbook Pro and Powerbook and 2nd Express (relay) connecting to Express via 80211g
iMac also connects to Airport Express via 80211g (in addition to direct ethernet connection)
So.... here's the problems....
Macbook and iMac cannot speak to each other. Macbook can see iMac's itunes but gets an error when tyring to connect (unspecified error - make sure port 3689 is open)
Cannot do a 'connect to server' either way between macbook and iMac.
iMac can see and connect to both Powerbook and Macbook Pro. It can also see itunes library on both of thses and vice versa.
HELP!!!

Help in order to connect iMac and macbook air

please could u tell me how I can connect my iMac and my macbook air in order to exchange document or file. Thank you

You don't specify the particular models of iMac or Air.
With that in mind I can only guess. My guess is that they are both the current model, both with Thunderbolt.
In addition to the above recomendation, you can use a Thunderbolt cable, available from Apple to connect the two computers.
This article explains how.

Connection iMac and macbook pro retina

I am newbie to mac and apple computers. I just bought the mac book pro retina display. My lab owns an iMac which I have no idea what the model is (probably before mid 2011). I am trying to use my iMac as an external display from my macbook pro retina. Do you think it would work with mini display cable or thunderbolt cable. I am trying to avoid paying for thunderbolt cable as they are so much more expensive than mini display port. Thanks

Although Target Display Mode was offered on some previous iMacs, I understand that it is not available on the Retina 5K (supposedly because the current DisplayPort standard doesn't support a high enough refresh rate to drive a 5K display).

Firewire to connect iMac and MacBook Pro

My MacBook Pro (Early 2011) is full, and I want to transfer pictures and videos to my fairly empty iMac (Mid 2007) with a firewire. Which firewire do I need?

You need a cable with a FireWire 800 port on one end and either a FireWire 400 or 800 port on the other.

Troubleshoot the network as that is likely what is causing the issue.
Also, temporarily disable the firewall on the Mac and disable IPV6 on the computer.

thank you, I have the adaptors so glad that would work. I just heard adaptors burn out often. So Just thought for my main iMac computer, a plug would be best. I will get one once I move.
Any other suggestions or things I should know about apple products in Ireland. I know there are no Apple stores there.
An adaptor doesn't burn out. It merely serves as a means to connect the power prongs on your device to the power supply.
I believe you are thinking of a transformer, which you do not need. A transformer converts one voltage to another.
You don't need to do that as the power supply of modern electronics can take almost any worldwide voltage.
Look at the label on the device. It should indicate the input power acceptable of 100-240 VAC, 50-60 Hz.
Additionally, I found the adapters cheaper in the UK than I found them in the US. They were available in most supermarket chains. I wasn't in Ireland, so I can't say one way or the other.
If you have something that doesn't have that input power spec, it would require a transformer.
On other items like electric clocks or things with motors, you can connect them up to a transformer and the voltage will be correct, but the frequency may not. For clocks, that will cause them to not keep time well. For motors, they will burn out.

Intermittent iMac to Macbook Pro wireless connection

I have a 24" iMac that is connected to our house wifi network. It is a TimeCapsule and there is a Mac Mini, Macbook Air and a Macbook Pro all on the same network. I can connect to all the computers from my Macbook Pro but occasionally I won't be able to connect to the iMac. We also you Rowmote Pro, an App on our iPhones. It connects using the same wireless network and when the Macbook Pro losses the ability to connect to the iMac the Rowmote also stops working with the iMac. When the Macbook Pro tries to connect to the iMac I get, "Connection failed. The server "iMac" may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again." At that exact moment I can see the iMac on my sidebar and all the other computers except the macbook pro can see AND connect to the iMac. I also can't go from the iMac and connect to the macbook pro but the iMac is on the network and connect to all the other computers. The iMac also has an internet connection through the TimeCapsule. I also reinstalled the OS and restarted and still can't connect. The worst part is that it switches randomly, sometimes I can connect and sometimes I can't. I am completely stumped!

Unless you have a wireless base station already, you could use the AirPort Express for that. That is, connect the AirPort Express to the Ethernet output of the cable modem.
It is possible to install an AirPort card (may be difficult to find today) into a G4 iMac. This would allow the iMac to establish a connection with the base station (wirelessly). Alternatively, a wireless Ethernet bridge (such as D-Link DWL-G820, Linksys WET54G and Linksys WGA600N; attached to the Ethernet port of the iMac) would provide an external solution. A wireless Ethernet bridge does not require special drivers and can thus be used with most Ethernet devices under almost any operating system. Even a USB wireless adapter may work, but only if suitable Mac drivers are available.
If you do not want to use the AirPort Express at all, you could buy (for example) an AirPort Extreme Base Station instead. The WAN port connects to the cable modem. The LAN ports make a direct wired connection to the iMac possible.

How to connect my new MacBook Air to a LaCie hard disk with TIme Capsule backup from my old Imac? LaCie has USB 2.0, FireWire and eSata ports.

How can I connect my new MacBook Air to a LaCie hard disk with TIme Capsule backup from my old Imac? LaCie has USB 2.0, FireWire and eSata ports.

You can direct connect your MBA to the LaCie via USB 2 cable. If you have an Apple Airport Router you can USB connect the LaCie drive to the router and then use Airport Utility to configure it. Time Machine can access it either way.
