Photos not importing at JPG, but as HEIC
I have recently updated our iMac software to Mojave, and when trying to import photos (Photos 4.0) for the first time since updated, it was trying to re-import thousands of photos from my iPhone 7 (iOS12). It appears that this is because they are in the library as JPGs, but now are trying to be imported as HEICs. I don't want to have to tell the computer every time to not import those thousands of photos, but I"m not sure how to work around.
Also, I manually imported the most recent photos that were not in the library, and they were imported as HEIC files. I had tried to ensure they would be imported as JPGs - I have the "Automatic" checked under the Photo settings Transfer to Mac.
What have I done wrong? Or how do I remedy this?
I do not sync photos to iCloud. I have had My Photo Stream on, but have done that for ages, and never had any problem syncing with USB and duplicate files. Additionally, when I looked at My Photo Stream during this issue, it wasn't showing the last 3 weeks of photos on it anyways.
Also, I am not sure, but I am now thinking that it may have been the first time I was importing photos after changing to iOS12 on my iPhone.
Thank you for the help.
