    TDM between iMac and MBPro

    Has anyone used TargetDisplayMode on his 2009-2011 27" iMac along with a 16" M1-3 MBPro? I’m just wondering if there are any issues created between the two resolutions that each Mac has. Do you see the MBPros display well on the 2K iMac?

    High Sierra, Target Display Mode, and fans

    I updated a 2012 MBP from Sierra to High Sierra a few weeks ago. As an external monitor I always use a 2011 iMac in Target Display Mode (Thunderbolt). The iMac runs Sierra. Weird thing is, ever since the MBP HS update, the iMac seems like it's been running extra hot and the fans are definitely...

    Luna + Duet = three-screen success

    Longtime lurker, first time poster. I'm just so chuffed that this worked I wanted to share it with y'all. I made the mistake of buying an M1 iMac without researching whether it would support Target Display Mode and of course it does not. I spent an hour on the phone with three different Apple...

    Questions about Reviving iMac 2012 — Target Display Mode, Luna Display Unit, Bootcamp

    I have a late 2012 iMac, model A1419, with a dead hard drive. Apparently, this 2012 model can be used as a Target Display in certain situations, but probably not mine! My working iMac is a 2020 iMac, model A2115. It seems that I could spend quite a bit of money just to find out that my 2020 +...

    Hi All, A bit of help, please. I have a fairly good iMac pushing two target displays (two 2012 iMacs). When the displays are connected (USB-C to thunderbolt) they work fine -- so long as I am typing or working with the computer. However, some time after I leave the computer, the driving...

    iMac mid 2011 with Xeon, would target display work?

    Hello, I would like to upgrade an iMac 2011 27inch to a xeon processor (e3-1280). However, the iMac also serves as good monitor for a mac pro. From what I gathered online, xeon will work but it would loose sleep function. Does target display mode put the imac in sleep function? if so, would it...

    Hi Friends, I have 2017 MacBook Air. I'm using a 2010 iMac 27" in Target Display Mode as an extra monitor. I can't find this answer anywhere else online but I'm wondering if running the extra monitor in Target Display Mode uses extra CPU power from the MacBook. I'm sometimes struggling to...

    DisplayPort display emulator plug

    As I understand it the M1 macs do not support target display mode. I have a 2011 27” iMac which I would like to replace with a new M1 Mac mini. However reading these forums it appears my iMac will not function as a display for the mini in target display mode (through thunderbolt). It occurred...

    New iMac 5K (August 2020) supports Target Display Mode again?

    Since the first 27-inch iMac with Retina 5K display was released in 2014, Apple discontinued Target Display Mode for those models going forward. This was due to various technical limitations that were never overcome -- until today (potentially), with the release of the updated iMac 5K with the...

    Using mid-2011 iMac as display

    I have recently purchased a brand new MacBook Pro, and was hoping to use my mid-2011 iMac as a display, rather than cowering over the small screen on the MacBook Pro itself as I work from home a lot. This article on Apple's own site suggests it should be possible...

    Target Display Mode- Let Apple Know To Add This Back

    Everyone needs to go to www.apple.com/feedback and tell them to add target display mode back to their iMacs. This feature was available from 2009-to early 2014 iMac models. Apple won't know unless everyone lets them know that was an awesome feature that needs to be added. I am stuck with a 2010...

    Can I use my iMac as a gaming PC monitor?

    UPDATE: On July 28, my iMac died. We had 7 great years together, but the GPU gave out and I've moved on to a PC, rendering this thread moot. I have a 27" 2011 iMac that I want to use as a monitor for a gaming PC I plan on building. I understand this will only work if I have a special device...
