You're not going to find a Thunderbolt 3 to Thunderbolt 2 cable as an adapter is required to connect to legacy devices. One of the (major) differentiators between Thunderbolt 1/2 and Thunderbolt 3 is that Thunderbolt 1/2 required the cable to be active (it required power to operate) whereas Thunderbolt 3 can use standard USB Type C cables (it's passive)1. ...

I don't think a straight-up cable exists, no. However, you can get an adapter/dongle that works perfectly well for your scenario. You'll need to Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter: https://www.apple.com/us_smb_83039/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter You can read more about the adapter here: https://...

For the display, yes: Target Display Mode. In this mode your iMac can serve as a display for another Mac. This is supported via the Thunderbolt port using a Thunderbolt to Thunderbolt cable (not supported via a Mini DisplayPort cable) source: http://support.apple.com/kb/HT5522 For the rest of the devices, theoretically not: 7. When I have a ...

If you really don't want to do it over the network, the retina MBP's display uses DisplayPort internally. You could disassemble your machine and use this pinout to connect it via Thunderbolt.

There are two options that I'm aware of which may meet your needs: Use the 1Keyboard app. This allows you to pair your computers via bluetooth and then use 1Keyboard to send the CommandF2 keyboard shortcut. It basically allows you to use one keyboard with multiple devices. Use VirtualKVM. This was designed specifically for people wanting to use their iMacs ...

Yes an iMac will work as a screen for a regular PC, but only with 27" models of Late 2009, 2010 iMacs. If those conditions are met then the iMac supports what is called Target Display Mode, aka using your iMac as a display. Also you will need a Display port to mini display port cable, they do exist as sold on Monoprice and at other fine online retail ...

Target Display Mode is right out since the hardware doesn't support it. What about using one of the networked applications (Air Display, Screen Recycler, etc) and running it over Thunderbolt instead of WiFi? If you have two Macs connected by a Thunderbolt cable, there's a Thunderbolt Bridge network interface that runs at 10Gbps, which might solve your speed ...

The specifications for the 24" Early 2009 iMacs according to eveymac.com and the Apple Manual for the Early 2009 series of iMacs does not mention target display mode as a feature. That unfortunately means that the Early 2009 generation of iMacs did not offer a target display mode so you will not be able to use that displayport output as an input source.

As I understand it you want to alternate between using the iMac display to display a) itself b) a connected MBP c) a simultaneously connected Mac Mini When you enter Target Display Mode, you do this on the target, i.e. the iMac. There is no option to tell the iMac which connected computer to display, if there are multiple connected. According to Use your ...

Sorry, no. There are some PCs and motherboards coming out now that support Thunderbolt, but because of how Thunderbolt works, it's not something that can be added on later to something that didn't initially support it.

I solved this issue using a Griffin PowerMate (basically, a USB-wired button) and some AppleScript to switch Bluetooth off on the iMac, freeing up the keyboard and mouse so my MacBook (connected via TDM) could take over. It's very smooth (as smooth as can be for something non-standard). I just connect my MacBook to the iMac, hit cmd+F2 on the keyboard, ...

If you can touch the cable and have it drop in and out, I would say you either have a bad cable or bad connector (or both?) on one of the computers. Try your setup with a different cable and see if you get the same result. Good luck!

My 13" 2016 MacBook Pro drives my late 2009 27" iMac's display using a third-party USB-C to Mini DisplayPort adaptor.

According to this article on AppleInsider the 2017 4K and 5k iMacs do not support target display mode.

With Maverick you can set up the network accross Thunderbolt. Be sure both machines are Thunderbolt and make sure to add the "Network" interface in "System Preferences". Then you can use AirServer on the Retina but not sure the latency will be great (as sending the image using TCP)…

I found a way to do it with an old, white apple keyboard, haven't tested with others but it might work. I used a tool called Karabiner from https://pqrs.org/osx/karabiner/. When you install it, enable following options to get Command + F2 to work: F1..F12 to Functional Keys (Brightness Adjust, Music Control, etc) - F1,F2 to Brightness Adjust --- F1 to ...

If your main priority is just not to replace the HDD, why not install macOS onto a USB flash drive and use that purely so you can use the iMac in Target Display Mode? To do this, follow these steps: Boot your iMac from the USB flash drive Ensure the other Mac is also booted up and logged into a user account Connect the two Macs with a Mini DisplayPort or ...

No, you cannot go into low power mode while in Target Display mode. While your iMac is "acting" as a "passthrough" for you display signals you are not bypassing the logic board and GPU to connect to the display. The iMac display is still connected to the internal logic board and GPU and that GPU is required to display images on the screen. The fans are ...

It's not possible to use Target Display Mode to connect a MacBook (Early 2016) to a 27" iMac (2011) For the Mid-2011 through Mid-2014 iMacs, you need a Thunderbolt cable and Thunderbolt isn't available on the Early 2016 MacBooks From the Thunderbolt Support Page A Mac notebook or desktop with a Mini DisplayPort or Thunderbolt port. From the MacBook (...

I'm pretty sure it can't be done - but I can't find anywhere that categorically says so. Two reasons in your particular case. The iMac 2013 needs Thunderbolt to Thunderbolt, not mini Display Port. Both machines need to be running macOS to enable the function. Macs running Windows in Boot Camp cannot use Target Display Mode. Background info from Apple KB -...

I have had the same problem with my 13" 2018 MBP to my iMac 27-inch, Late 2012. Talked to Tech support for weeks at the advanced levels. They told me they are working on it and look for a firmware update for both the laptop and the iMac. Bought my MBP when they first came out, it is now September 3, 2018 still no update. Still does not work. Have not ...

On closer inspection, it looks like the display is not actually uniformly black. This led me to conclude that perhaps the backlight was just not turned on properly, and led me to discover the following workaround: Log into the iMac Change the brightness to a different level (e.g. up or down by one). The level seems to need to be different from the one ...

Here are the iMacs that support Target Display Mode: See more: https://support.apple.com/en-us/HT204592

According to http://support.apple.com/kb/HT3924, no. But it might be done with Screen Recycler. As far as I know, Apple has no official support for this.

To your 2nd question: I've not been able to toggle target display mode with a non-apple keyboard, however I was able to accomplish this using the app 1Keyboard. Basically I paired the computers via bluetooth, then used 1Keyboard to send command+F2. Sending command+F2 via Apple Remote Desktop did not work. I also tried sending command+F2 programmatically, but ...

What I have found out is that TDM (Target Display Mode) on my mid 2010 27" iMac only works with the following resolutions: 720p (1280*720) or lower Native (2560*1440) Any device that tries to output something in between, gets a signal it has to change it's resolution to 1280*720. Many devices can automatically do this (Xbox 360, PS4), but some can not (PS3,...

I'm experiencing the same problem. I have a current generation 5K iMac which I use as my main computer, and a 2009 iMac which I use as a second monitor using TDM. In TDM mode, the older iMac runs painfully hot. Switch back to regular mode, and that same iMac runs cool. Typically, I don't even bother to login to the older iMac - I just turn it on and off ...

In order to switch displays you either need to shut down or disconnect the computer using the monitor i.e. the display "remembers" the active port and will only switch if this original source is turned off or disconnected. But you can use a physical DisplayPort switcher like this one : http://www.kanex.com/snapx Two Macs, One Display Winner of ...

VirtualKVM will allow you to use your "iMac as a monitor for [your] Macbook". This is super easy and free.

I was going to just leave a comment to existing answer, but I don't have enough reputation for that, so I'll just write it here. I'm running AirServer on my MacBook Pro, and I'm using it as a AirPlay monitor for my much more powerful hackintosh desktop. I can confirm that when using gigabit lan instead of wifi, performance goes up and latency goes down ...
