Installing Programs

Eric, Welcome to Apple Discussions !

Assuming that the programs you have downloaded are compatible with Macs and your OS --

You will have a dmg file on the desktop.
Double click it.
That will open up a pane that will have the application's main icon,
and possibly a "read me" file.

Take the application Icon
and drag it into your open Applications folder.
(Macintosh HD icon>Applications.

Double click on the new application's icon
to open it for the first time.

After you're sure it works properly, you can
get rid of the .dmg file, plus the installer icon file
(rectangular white thingie) from your desktop.

That's it in a nutshell.

Eric did mention "Myth2_demo.img.sit" in the other post about downloads.

I had the same puzzlement with .sit files when our iMac came & I needed a Samsung printer driver.


Eric - .sit files are a compressed format - like .zip files, except you need a program called Stuffit Expander to unzip them. ( are there other ways?)

From my limited knowledge - it seems that .sit was the standard Mac compressed format for years & years & the program came with the OS - now it's not, & all the software suppliers are s'posed to use .dmg - but you'll still find some downloads as .sit files.
