Photos (Moterey) crashes when I add pics

i tried retitling it in the info panel, and now when i try to add it Photos does not crash, but gives me the message "Cannot Import Item This item cannot be added to your Photo library because it may be an unrecognizable file format or the file may not contain valid data."

it is a .jpg that both photoshop and preview open without issue, so...

hi Tony-

thank you so much for taking time to reply.

the library is not new, it has been in place since Apple first changed over from iPhoto.

it is store on an external hard drive, where it has always been.

since posting, i have discovered that some of the photos will add to Photos and some will not - odd again, since they were all altered / generated in Photoshop and as the same file format, jpeg. i cannot remember Photos or iPhoto refusing to accept a jpeg before, especially since, as i said, the photos that crash Photos open in Preview...

i'll try the safe mode method when i get home from work tonight.

thanks again,

matthew

formatting is correct; not a previous time machine disk (though i always reformat anyway); hardwired.

your note about color profiles may be the ticket here - i have never heard that and haven't run across that issue during my searching for solutions here. several of the photos are black and white, so i will re-save them as RBG and see if that solves the issue.

thank god for you and your willingness to take time to reply, you're the best!

well while it wasn't necessarily the color profile, it was something about the file format. some older scans i did in photoshop list as jpegs in finder, but appear in folders without the file extension. these were the ones that wouldn't add.

i reopened them in photoshop and re-exported as jpegs and now they can be added.

not sure what the precise technical problem was, but i have a solution and o\your suggestions got me there, so thank you again. posting this for any others with a similar issue who come a-lookin'

with graittude,

matthew
