Can Fireworks files be used across Macintosh and Windows platforms?
Yes! You can share your Fireworks PNG (Portable Network Graphics) files with other Fireworks users on either Macintosh or Windows platforms. The source PNG file is always editable. The fonts used for text in the Fireworks file will of course not be identical to those used on another platform so users are advised to have the same fonts installed on their platform as those used on the platform on which the file was created.
