MacBook air has reached its limit a few times, So I took it into Apple to have them delete all photos from macbook air and transfer to external hard drive.
The thing is, in lightroom, when I open open photo, the photo is showing this file could not be found??? Why???
I suspect it is because you had had the images moved from the position where they were cataloged.
