Find my phone>. Mac Desktop not appearing on find my phone but all other devices are.

dmsheldon,

Thanks for getting back to us. We're sorry, I think we now understand what you mean by a Mac "desktop" you're referring to your actual Mac computer. We have a great article that explains how to enable Find My on a Mac. You can see how this process is done here:

Set up Find My on your iPhone, Mac, and other devices 

Specifically, check out the section labeled "Get started with Find My on your Mac"

Hope this helps.

Best Regards.

Hello dmsheldon,

Thank you for using Apple Support Communities! I understand from the information you provided that you’re unable to see your mac desktop on your other devices; I'd like to help.

Just to verify, are you looking in the right place for your desktop files? Here's a resource that could help:

Use the Files app on your iPhone, iPad, or iPod touch

Also have you enabled the option to share your desktop:

Add your Desktop and Documents files to iCloud Drive

With regard to you iPhone not showing up in Find My, make sure that iPhone is sharing it's location:

Share locations in Find My on your iPhone and other devices

Hope this helps.

Best Regards.
