Non-Portrait Photos Appear As Uneditable Portraits In Photos
My environment is Apple Photos 8.0 (560.0.110) on a 2019 27-inch iMac running 13.6.6 "Ventura". My Photos library is stored on an external USB SSD formatted as Mac OS Extended (Journaled), with the Ignore ownership on this volume flag set. The problem I'm experiencing also happens under my wife's account on her 2023 Mac Mini (same OS, same version of Photos). We are not using iCloud in any way, not for anything: it is not enabled on our Macs, nor on our iPhones. There have been no changes or updates to either of our Macs at least in the past 12 months. However, we have both recently upgraded our iPhones from iPhone 13 running iOS 17.x, to iPhone 16 running iOS 18.0.
I prefer not to use the "Portrait mode" feature of my iPhone. I have determined how to disable this feature and have done so by turning off Settings > Camera > Portraits in Photo Mode. However, before I did this, I unknowingly took a few photos that appear to have this feature enabled--and by "enabled", I mean that the camera app appears to have saved some kind of metadata for a few of the photos that allow "Portrait mode" to work. These photos, when viewed on the iPhone, have a dropdown listbox labeled "PORTRAIT".
The problem is, when I "turn off" Portrait mode for an individual photo in my camera, and then import that photo, it shows up in Photos with the label "PORTRAIT" stamped on the photo. However, when I attempt to edit the photo to turn off or eliminate the Portrait effect, no options are presented for editing the Portrait settings. Here is a specific example. On my iPhone, I have a photo of my cat that has the "Portrait" dropdown list stamped on it. When I tap the dropdown, I can see it is set to Portrait Off.
However, when I import the photo into Photos on my iMac by attaching my iPhone with a USB cable, the photo appears with the PORTRAIT label on it.
When I attempt to edit the photo, there are no options for adjusting or turning off Portrait.
I have seen some posts online that refer to "the bottom of the edit screen" for accessing the Portrait editing capability, but I can assure you there is nothing at "the bottom of the edit screen".
I have done extensive searching online, and I see many other people posting about this same problem, but I don't find any solutions. For example, here is a post on StackExchange that exactly describes the symptoms of the problem, complete with screen shots (although in that post, the OP transferred his photos using AirDrop and there is some suggestion that the Portrait metadata got lost; that isn't relevant to my situation since I'm transferring directly from iPhone to Mac using a USB cable).
Here is another thread on Reddit that states the problem was a bug acknowledged by Apple support in macOS 12.x "Monterrey", but I'm on 13.6.6 "Ventura" and I can't believe the bug still exists.
So I guess my questions is, since I don't care to use Portrait mode anyhow, how can I completely strip out/remove anything to do with Portrait mode, either on my iPhone before I import the photo, or in Photos after I import the photo? I'd really like to not have "PORTRAIT" stamped on photos in Photos, especially if the Portrait mode data can't be accessed or edited anyway.
