Based on the specs you provided above.... I have a 2012 MBPr and a late 2012 21" iMac.... This should work. From Apple's website Use your iMac as a display with Target Display Mode Basically you need a Thunderbolt cable to connect from your TB port on your MBPr to your TB port on your iMac. Once connected and booted, you just press CommandF2 to ...

Yes, in the sense you can share the screen over a internet connection. There will be a noticeable small delay as information is exchanged over the internet connection. What you would normally see on the iMac is the same as seen on the Mac Book Pro. The displays would mirror each other. If you had an actually external monitor connected to the Mac Book Pro and ...

I ended up updating iTunes then signing in, after the update completed and a restart. Once the iTunes sign in was successful everything else was able to sign in. Hope that helps someone.

The Display Port on the 21.5" iMac is output-only, so you can't use it in target display mode.

You can use this great open source tool: https://github.com/Eun/DisableMonitor Tested on iMac (20-inch, Early 2009) with OSX El Capitan 10.11.4 and Dell U2515H external monitor via DP

Realise this is quite an old thread but was helpful for me today! After a bit of searching around I managed to do it - You can make a USB install disk by re-downloading the OS on a separate Mac but not installing it. (I'm currently running OS X Yosemite) You should end up with a 'Install Yosemite' file in your application folder. Get a program called Disc ...

My late 2009 iMac works as an external display for my Early 2013 15" Retina MacBook Pro, and for my Mid 2014 15" Retina MacBook Pro, using this cable. Both laptops have Thunderbolt; the iMac does not have Thunderbolt. I don't have a Late 2013 Retina MacBook to test, but it seems reasonable to assume it has the same compatibility.

I had the same thing happen - the setting in Accessibility->Audio is turned off, but the screen flashes anyway. I wonder if it has something to do with using LogMeIn. It has a long-standing bug of not switching your audio output/input device back to the built-in speaker/mic after a remote session closes. During the session, sound is routed through a ...

A good first step towards debugging power management-related issues on OS X is: pmset -g assertions It can take a little practice to read the output, but it can lead to finding processes that are erroneously making power management assertions against the kernel. It can also be an iterative process — keep running it at appropriate times, ad see what crops ...

It could very well just be the slow-ish hard drive. Apple generally does not put 7200RPM drives in its Macs. While it could be the O/S and it might be worth your while to image the internal drive onto an external drive and wipe the internal and start fresh with the OS and Apps. Depends on what is more valuable to you time or money. An SSD WILL speed up your ...

To finish this question: I had opened a bug report with Apple. They determined that a botched Aperture photo library migration lead to excessive disk I/O. In the end, I reformatted the whole Mac. Plus to make the machine more useable, I attached a 256 GB Thunderbolt SSD and created a FusionDrive, as per this blog (in german). There are lots of howtos ...

You could try going into System Preferences > Displays > Arrangement and check Mirror Displays. From here, unchecking it should bring all your windows back to your main screen.

Voltage fluctuations are normal. I am assuming you are in the UK or Europe. If so, your voltage should be between 220V and 240V so everything is within range. Besides, the UPS is designed to "smooth out" these voltage fluctuations so your power is clean coming into your Mac. What is key to finding out what your issue is what the shutdown code is in your ...

Try checking your Energy Saving settings in System Preferences. You can tell your Mac to wake up at a certain time from here. If that does not solve the issue, you may benefit from resetting the System Management Controller. To reset the SMC: Turn off and unplug the mac. Then, after waiting 15 seconds (the times are important), plug the mac back in. ...

This sounds implausible, but do you live in a multi-floor building or near a loud street where some kind of heavy walking or loud noise may be physically shaking your desk just enough to move your mouse? It doesn't take much to wake up the mouse, and thereby wake up your computer.

You may have malware using up resources. Clean it up with Malwarebytes Anti-Malware for Mac (formerly known as AdwareMedic). You download their free app and clean things up. Here is the link: http://www.adwaremedic.com/index.php The program will identify malware and optionally remove it (you should almost certainly remove it). Malwarebytes Anti-Malware ...

There are 3 main possible causes for your issue. When experimenting described slow downs, follow these steps: 1 - RAM: Go to Activity Monitor > Memory. Look at the graphic at the bottom of the window, it is called "memory pressure". It will show you if everything is ok (green), not so much (yellow), or if it is out of memory and it is swapping (red). 8GB ...

You need to go to Keyboard Preferences and add a new keyboard. Instead of using USA International keyboard you will need to use USA Keyboard. So from Use instead When you are going to add a Keyboard you select English. At the end of the list you will see both keyboards. Use the one that is not international.

You can find the combinations to many more symbols by opening "Keyboard Viewer". The combinations in here should reflect your current keyboard layout as specified under System Preferences > Keyboard. To open Keyboard Viewer, click the menubar keyboard icon (if you don't have it, it's enable it from System Preferences > Keyboard) and select "Show ...

Well, that did not work. Now I'm going to try this in Terminal.app for 5 hours of "don't go to sleep on me": caffeinate -t 18000 Info on that command is: man caffeinate

User error ... I had to use the command+comma shortcut to change preferences. I had foolishly checked "Hide icon in Dock" not realizing that it would also hide it in the application switcher.

Everymac says your machine can support two external displays up to 2560x1600 via Thunderbolt, so I think the answer would be no.
