MAC OS 10.1.5 -- Can't Install .DMG files?

Question

I'm new to MAC. I recently received an older MAC - Version 10.1.5 . I very quickly learned that the typical installer package for Mac OS is .DMG . I opened up the installer and attempted to install Firefox. When the installer is open, and I browse for a .DMG file, The .DMG files are grayed out, and the installer cannot access them; Thus I cannot install any programs.

Can someone explain to me why these files are grayed out and why they cant be accessed; or installed?

Answer 1

Mac OS X 10.1.5 is not compatible with any Firefox like 3.6 or higher. I would upgrade that "older Mac" to at least Mac OS X 10.4.11 if you could find some Mac OS X 10.4.x discs. You can install only compatible DMG files that work with the current version of Mac OS X.

The thing is this: .DMG files are NOT the installer packages, they are 'disk images', like the .ISO files that you may know from the Windows/Linux world. OS X has a built-in program to mount disk images (that is: 'open' them as if you plugged in some USB drive.) So you just double-click the downloaded .DMG file, and a storage drive symbol will appear on the desktop, as if you plugged in a USB drive. This disk image can contain any file that any drive can contain.



A software installer package—in Windows typically known as .exe file—would be a .pkg or .mpkg file on OS X (file extensions are by default hidden from the user). You run installer packages by simply double-clicking them, which launches OS X's installer application...



Other applications that are delivered in DMG files don't need any installer. Firefox is one of these. After double-clicking the icon of the mounted DMG file, a Finder window opens and reveals to you what is stored on that image of a 'drive'. To install the application, you just drag its file from the DMG window to the hard drive, usually the Applications folder – just like you would copy a file from an external USB drive to the internal hard drive. Often software developers also provide an alias file of the Applications folder in the DMG file (icon has a little curved arrow). In this case, you can also just drag the application file onto the alias to copy it to the Applications folder.



Hope it's clearer to you now.



EDIT: I just realized that you wrote OS X 10.1.5 – this is indeed an ancient version. Are you sure it is not 10.5.1?

This document format is contained in the fashion of a Mac OSX Disk image. you need to remodel the .dmg to .iso. the application for replacing is given below. set up the application and then convert the disk image or perhaps as that's switched over to .iso burn it onto a dvd utilising any burning application like nero,etc.
