I bought recently a macbook and when I want to resample an image (from circa 25x25 cm/300 dpi to 50x50 cm / 200dpi), thing I often do, on the photoshop installed on the mac book, it doesn't work at all. You can see the picture transformed by this operation.
When I do it on my windows computer, it works normally.
Is there something checked by default ?
Is it a known bug on Mac ? on Photoshop ?
I downloaded the last Photoshop version a couple of days ago. But the result is still the same.
