Imported iPhone photos in png format not shown on Photos app
Hi,
I have recently brought my computer to apple store to check if there's a defected ssd in my MacBook Pro. There was no problem so I got my computer back on the same day but everything was wiped out. Before I bought it in, I've made a backup on my time machine, with photos imported from my iPhone SE to Photos app. On the same day, I've got a new phone with my old SE traded in for instant credit, so I don't have an access to my old phone. I didn't have iCloud turned on for photos so I know they're not there.
When I restored my computer with time machine backup, opened photos app, and I see some of my old photos and new photos are shown as a grey square, not a full image. when I checked the info of it, its format is .png, not .jpg like those photos I could see. Also, I can't locate those files with png extension on my computer.
I've tried restore photos with option-command and it didn't work.
Any suggestions?
Thank you.
