After upgraded to os 11.2.6, my iphone X got this issue. When it connects to mac or windows, live photos are missing from the connecting device. Explorer on windows, and image capture or photos on mac.
iPhone X, iOS 11.2.6
Which system is running on your Mac? The Live Photos may be using the new HEIC/HEVC codecs, and only macOS 10.13.x can read this format. If your Mac has not been upgraded to High Sierra, consider to upgrade or set the iPhone to download the photos and videos in a more compatible format.
See: Using HEIF or HEVC media on Apple devices - Apple Support
When you import HEIF or HEVC media from an attached iOS device to Photos, Image Capture, or a PC, the media might be converted to JPEG or H.264.
You can change this import behavior in iOS 11. Go to Settings > Photos. In the "Transfer to Mac or PC" section, tap Keep Originals to prevent the media from being converted when importing.
After changing to Keep Originals and back to converting. The newly taken live photos work. However, the previous taken live pictures still have issue. I can view them on the phone, but I am not able to view them on computers.
I changed to Keep Originals, and it didn't help.
My mac is 10.11.6.
The issue is not importing. This issue is that I am not able to view it. Therefore, I cannot import.
I was able to see both jpeg and mov files before upgrading to ios 11.2.6.
