I don't think it makes a great deal of difference. Occasionally, Adobe will release more advanced versions for Windows before the Macintosh version (for example, the 64 bit version of Photoshop is only available for Windows), but for most purposes it works well on both systems.
The best computer is the mac but the best program (I think) Photoshop, is for PC
yes
no. you have to get the mac version of photoshop
Mac is a PC. You meant windows? Yes, windows can do much more than a Macintosh.
NO and don't try
Flash is an adobe program just like Photoshop and Illustrator. It is the same on both mac's and pc's.
To launch Photoshop you would simply go into the start menu on a pc and click on photoshop, double clicking on the icon in Applications on a Mac computer, or by double clicking the shortcut icon from the desktop on either a Mac or Pc if you have a shortcut.
That's called a "cross grade" and you need to contact Adobe Customer Support. The serial numbers for Photoshop are platform specific, so can't be used across platforms.
Yes you just have to have the correct version of Photoshop for a Mac.
Photoshop files use the extension .psd in Mac OS X.
The best place to go online to purchase the Adobe Photoshop software for a Mac would be at the Adobe website itself, though one can also purchase it at retailers such as Amazon.
Use Adobe Photoshop for advanced editing or just use PowerPoint (PC) or presentations (mac) for simple changes to a picture
