Issue installing PSE13 on my MAC

Question

I am tryint to install PSE 13 on my MAC on OS X 10.10.2 Yosemite and my MAC is just spitting the disc back out.  It will read other discs like dvd.  Have you had this issue with anyone else or do I need to contact MAC support?

Answer 1

Downloading as we speak, and the first explanation that comes to mind is that both files have a .rar extension, and that since OS X doesn't support this archive format, you need to install a third-party utility to open them.
One files tool to open .rar files is The Unarchiver (here), and another is Stuffit Expander (there). 7zip also proposes a Mac version (here). All three will decompress a .rar file, and let you access the .dmg file(s) inside.
Also, depending on the browser you're using, and provided you might be inclined to open trusted files directly (I use Opera, and seldom save safe download; I click on "Open" in the download dialogue), your files could very well open... in the browser cache folder, out of sight. But if you use Safari, Chrome or Firefox, and you don't have any utility installed to handle .rar files, that's doubtful. I'm going to open your files now, and check if I can install them.
Stay tuned!
Edit: decompressing the first file using The Unarchiver shows that the archive is "incomplete". Which leads me to think that you might have to concatenate the two files to make one "complete" .dmg file.
If so, once they are decompressed, open a Terminal (in Applications/Utility), then type "cat", and drag both files in the window, one after the other (preferably in the right order...), type a space, then give the final file any name you want, followed by the .dmg file extension:
(e.g.:) "cat /Users/Your_Name/Desktop/File1.dmg /Users/Your_Name/File2.dmg /Users/Your_Name/Desktop/FinalFile.dmg"
