Unable to connect iPhone SE2 to iMacM1 using USB cable

Hi SantaSadler,

Thank you for using the Apple Support Communities! If your iPhone does not appear in the sidebar in Finder, the steps below may help:

If your device doesn’t appear in the sidebar when connected to Mac

If you connected your iPhone, iPad, or iPod touch to your Mac using a USB cable and don’t see it in the Finder sidebar, check the following:

•Check that the cable is properly connected. When your Mac and device are connected correctly, you should see that your device is charging. 

• Make sure that the device is unlocked and the Home Screen is visible.

•Check that Finder settings are set to show your device in the sidebar. See the instructions below.

Set Finder settings to show your device in the sidebar

1. Connect your device to your Mac.

2. You can connect your device using a USB or USB-C cable or using a Wi-Fi connection. See Sync content between your Mac and iPhone, iPad, or iPod touch over Wi-Fi.

3. In the Finder  on your Mac, choose Finder > Settings.

4. Click Sidebar.

5. Below Locations, select the CDs, DVDs, and iOS Devices checkbox.

6. Check the sidebar again, below Locations, to see if your device is showing. 

7.

8. Click the device to see the syncing options.

If your device still doesn’t appear in the sidebar, see the Apple Support article If your computer doesn’t recognize your iPhone, iPad, or iPod

Hope this helps!

Have a great day.

Hi there SantaSadler,

If you followed all the steps suggested previously and you still can't see your iPhone in Finder when it's connected to your iMac, upgrading your iMac to the most current software version is the next best step. The most recent release is macOS Ventura 13.5. If needed, learn how to upgrade the software on your iMac here: How to upgrade to macOS Ventura - Apple Support

Take care.

Hello SantaSadler,

Thanks for those details.

At this point, please reach out to Apple Support directly, as this may require closer guidance: Get Support
