Why can't MacOS give a correct preview of my PS images?

Some images show a preview in the finder and some don't. I've tried saving the images different ways (jpg, psd, etc) and in different bit modes-but still nothing shows up. Or sometimes small parts of an image show up, like it's masked or what's on one of the layers like a partial section of the image. Anyone know how to get the whole image to preview?

It's been bothering me for some time.

That preview comes from MacOS. And MacOS's image preview code has a lot of bugs in it. Sometimes the MacOS preview code crashes on TIFF, PDF and PSD files (and takes Photoshop down with it).

Flat 8 bit RGB documents without alpha channels or transparency seem to get reliable previews. But CMYK, 16 and 32 bit/channel, alpha channels, transparency, etc. seem to confuse the MacOS preview code.

The only real way to fix that is to ask Apple to fix the bugs in their preview code.

Until then, just realize that the OS preview isn't always going to work.
