This pc/Mac compatibility on any file/program/issue is just crazy in this digital word. It's far time the people/companies who make our computers get their act together for everyone's sake.
For clarification, I meant files I made in Photoshop on my Mac....can be opened by almost everyone but my sister, .

Also depends on where you got the file from. Was it on a disk or emailed to you? Sometimes image files sent from Mac to pc through a Mac email (as opposed to being sent by Gmail, etc.) cannot be opened by pc. Sometimes when a Mac sends photo files to a pc, it used to include two files for each file (one for pcs and one for Mac). Not sure if emails from Mac do that anymore.

However you mentioned that the problem was "not enough RAM." Was is the size of the Photoshop file? If it's large (in dimension, resolution, or neither but has many "layers"), it could mean any one of the following:
1. Your version of Photoshop cannot handle such large files (if you have at least a Photoshop cs version, it should be fine.)
2. Your computer itself doesn't have enough RAM.

Just thoughts.
