How to "burn" (or write or clone) a bootable PowerPC disk image onto an USB stick in Mac OS X using "dd" in Terminal

This article lays out the steps in order to "burn" (or clone, or copy) a disk image (such as an ISO boot/install CD) onto an USB stick using only a vanilla Mac OS X environment that any Mac user already has available.  You do not need any additional or third party software since Mac OS X is Linux based and comes with "dd" which is all it takes to accomplish this. Read that other article if you're looking for doing...

How to "burn" (or write or clone) a bootable PowerPC disk image onto an USB stick in Windows

PowerPC Macs such as G3's and G4's can boot off of USB sticks, even if this functionality has been buried so deep in technical details that almost nobody knew about it until nobody used G3's anymore.  If you're a collector or hobbyist and got a G3 or G4 and would like to install Mac OS 8, 9 or Mac OS X on it but that the CD/DVD drive is broken, here's a complete guide that will prove to be useful to you.  It will...

How to convert .MDF/.MDS disc archives to ISO

This article focuses on what to install on your mac to allow for disc image conversion from MDF/MDS to ISO. The article covers Mac OS X 10.4 through Mac OS X 10.13.x which is the current version as of this writing. There are two candidates for solving the disc image conversion, a GUI program titled AnyToISO Converter Lite and a command line interface called mdf2iso. These two programs are not by the same author but...

How to convert a DMG file to an ISO disk image?

DMG files are disk images that are compressed using Apple's proprietary format and Mac OS X default disk image format.  The fact that the DMG disk images are compressed poses a compatibility problem to most Windows users and earlier Mac OS versions, e.g. Mac OS 9.  The ISO (a.k.a. CDR under Mac OS X) disk image format is universally supported, therefore it's a much better choice for storing files or making a disk image...

How to create a HFS+ disk image in Mac OS X to encapsulate/transfer Mac OS 9 and earlier files

Old Mac files (Mac OS 9 and earlier) need to be encapsulated properly before being moved/copied to a non-HFS partition/disk such as on a Windows PC or a web server or they will get corrupted, effectively losing their resource fork, which will render them useless on your Mac OS 9 or earlier environment. The best way to protect old Mac files before moving/copying them out of your OSX environment is to first copy them onto a HFS+ disk image,...

How to make/clone/burn install/boot floppy disks for old beige 1990's Mac?

This tutorial only applies to old Macs that have a regular 1.4MB floppy disk drive, NOT a 800KB or 400KB floppy drive.  800KB/400KB floppy drives were uniquely manufactured by Apple and cannot be emulated using a generic PC floppy drive at all, because they have special firmware in their boards that can pack more DATA per track than regular PC drives could, at the time.  Moreover, please note that even if you have a Mac floppy drive...

How to mount a disk image under Mac OS 7, 8 or 9

One of the problems retro Mac enthousiasts face nowadays is figuring out how to mount old/random disk images in order to access the game or app in it. First of all, you have to know that there were at least a dozen disk image formats back then (altough only a handful of them were widely used) and fortunately for you, there is a very nice disk image mounting tool for classic Mac called Virtual DVD-ROM/CD Utility that mounts just about all of them...

How to open most common old Mac archives on older Mac OS

This tutorial is meant for people who did not use older Macs back in the 90's who are struggling to open (or "load") old Mac files into their emulator (or even a real Mac, doesn't matter) and it's split in paragraphs that depict a specific file type/extension, so please skip to the paragraph that talks about the kind of file you're trying to open to discover how to do it.   .sit Stuffit archives Stuffit...

How to wrap loose old Mac files into a disk image (for use with FloppyEmu, etc...)

OK, so you got yourself FloppyEmu or a similar disk emulator for your old Mac and it works great, except not with all the files.  Why? Because FloppyEmu and such disk emulators are... disk emulators.  They expect you to feed them a disk image, not just random loose files. So just how can you wrap loose Mac files inside a disk image for use with FloppyEmu? Here's a full tutorial: 1) Grab a copy of this Disk image wrap tutorial...

I downloaded something that contains .bin/.cue files, how do I mount this under Mac OS 9?

Okay, first off, there aren't a ton of .bin/.cue files, but there are some and when you'll face them, you most likely won't understand how to deal with them because it's an awkward format.  Also, you have to understand that .bin/.cue files MUST work in pairs so whenever you see them, always keep them together in the same folder and do not rename them.  The .cue file is a cue sheet that explains to the disk image...

What is a .dmg file (disk image) and how to use it?

What is a .dmg file? A .dmg file is a disk image, meaning it's an exact copy (raw block DATA) of a disk (CD, DVD, USB stick, etc...) or even just a folder wrapped in a disk image.

What is a .toast file (disk image) and how to use it?

What is a .toast file? A .toast file is a disk image of a media (CD, DVD, USB stick, hard drive, etc...) created by an application named Toast.  Note that a .toast disk image is almost exactly the same as an ISO disk image and in essence, one could absolutely rename any .toast file to .iso and use/mount it as such.  Therefore, please see this page instead: What is a .iso file (disk image) and how to use it?
