- Apple released no new iMac in 2016 or 2018. Bought yours then? See 2016 and 2018.
- 2007 to Early 2009 (OS X 10.10 or 10.11): Encore Receiver Legacy. It decodes in software, so the picture is sent smaller (about 1440 × 900) and scaled up.
- Not sure which one you have? Apple menu → About This Mac.
- Target Display Mode rules as written on Apple's support page.
