cn i hook up my imac 27 inch 2017 to a 2022 mac mini M!
Can I use my imac 27 inch 2017 as a monitor for a new M1 mac mini
iMac 27″ 5K, macOS 12.6
Question marked as
No, because neither of those Mac’s support Target Display Mode.
carefully read all the requirements,
at > Use your iMac as a display with target display mode - Apple Support
Best bet is to get and use an external display with the Mac mini.
