I have two 27" imacs running mojave. Both are 2015 models. Can I set up one as a second monitor?
iMac Line (2012 and Later)
No. High Sierra was the last version with support for this, and the iMac 2015 is too new an iMac for target display mode.
Use your iMac as a display with target display mode - Apple Support
In short, Mr. Hoffman is dead on correct. If you need an external display you need to buy one. If you want to share an external display between the two iMacs I would recommend contacting OWC (www.macsales.com) and see what type of solutions they may have.
Thank you
Thank you. That is what I was seeing in searches but wanted to verify.
Your welcome.
