Is there a way of using a 21.5 inch 2010 imac as an additional screen for my 2017 MacBook air. The imac has a minidisplay port and the MacBook air has a thunderbolt port. I've got a mini display part cable.
I've tried connecting the two with the cable and hitting command f2 with no joy. Are there any other options?

Hi awhitehouse28,
We see you're wanting to use the iMac as an additional screen. Also be sure to use the steps in Use external monitors with your Mac.
Take care!
The 21.5" 2009 and 2010 iMacs can't be used as displays in Target Display Mode.
Use your iMac as a display with target display mode - Apple Support
Yes, there are other options. DuetDisplay and LunaDisplay are two. I use Duet display myself.
I hope this helps.
