Mac application install question when there is no dmg file
I will be getting my first Mac shortly, and I've been downloading some Applications for in preparation for when I get my Mac.
Some of the Applications I've downloaded, once I've unZipped the downloaded file (on my Windows PC), I then have a folder called Contents, inside this folder are normally either 4 to 7 folders and normally a couple of other files, which have the below names:
The folders:
_CodeSignature
Frameworks
MacOS
Resources
The couple of other files:
info.plist
PkgInfo
I was wondering if someone could explain to me please how I go about installing these as there is no dmg file?
Thanks in advance
