Preferred Formats for Software Preservation

Preparing files or discs are critical to the preservation of software here on the Macintosh Repository's archive and elsewhere for that matter. This article, although not exhaustive, should provide members with the knowledge necessary to gain a foothold of the terminology, a brief background and some possible steps to prepare loose files and physical discs for upload. EXTREMELY IMPORTANT: DO NOT ZIP AND/OR DO NOT MOVE AN...

Cannot lock, unlock or delete a file under Mac OS 9?

There was a bug under Mac OS 9 (and maybe Mac OS 8 too?) that, under a special circumstance, prevented some files to be locked, unlocked or even deleted.  They would sit there in your trash forever and prevent you to empty it even when the OPTION KEY is held down.  Rebuilding the desktop does NOT resolve the issue. Trying to get file info with ResEdit results in the following error: The reason this is happening is generally...

Corrupted/blank files when expanding a ZIP under Mac OS 9 and seeing a __MACOSX folder?

If you used a Mac back in the 90's, then you remember that among Mac users, nobody ever used ZIP format for compressing files.  Everybody used SIT files instead and some used HQX, BIN or CPT files, but not a single Mac user zipped their files.  The reason is simple: ZIP files are not compatible with Mac resource forks (old Mac files before Mac OS X) and zipping an old Mac file (such as a Mac OS 9 application program) would destroy...

Getting Started (WIP)

(the [messy] WIP guide) Hi enthousiasts or nostalgics from the not too far future! Ready to undust some of the 80's, 90's or early 2000's Macintosh Software treasures and feel what it was like in those earlier computer days but you're afraid it will be too difficult or obscure to do that by yourself? Fear no more, here's a small guide that will get you started!   Step 1: Real hardware... or emulation? First...

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 convert any video to play it back on old an old 68K Mac w/ QuickTime 2.5?

Back in the early 90's, there was no such thing as 1080p let alone 4K! But playing back small color video on a 25mhz Mac was possible thanks to QuickTime.  It supported only a handful of formats, but here I'll explain how to get any video from today playing back on a 1990's Mac. First, I need some video conversion utility such as XMedia Recode. Then, I configure a conversion queue in XMedia Recode with very specific...

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 disable the airport card in the mid 2005 iBook to prevent crashing

Many iBook G4 laptops (and possibly other models) have a problem with the inbuilt AirPort card failing, and then causing regular kernel panics. This can be avoided in Leopard, and possibly Tiger, by replacing the kexts responsible for the AirPort 1. As soon as you turn the computer on quickly turn off AirPort in the menu bar. 2. Open TextEdit and save two blank files to the desktop. Name the First one  IO80211Family.kext.rtf and...

How to display a custom StartupScreen picture on boot under Mac OS 9 and earlier?

Under Mac OS 9 and earlier, all the way back to the first Mac OS versions in the 1980's, you could display a custom boot picture in the background while Mac OS was loading. To do this, you do NOT need to alter/edit any system files at all.  All you need to do is to save a copy of your desired startup picture into a specific format and place it in your System Folder. Note: System 6 and earlier only supports black & white...

How to make a Universal Mac OS X Leopard Installer USB drive in Windows 10

This tutorial used this copy of Leopard, a 16GB PNY USB 3.0 Flash drive, and Windows 10 version 1909. An 8GB drive should work fine, but that is the minimum size I would recommend to try. You will also need to download TransMac. The version used in this tutorial is TransMac 12.6. Note: TransMac costs $59, but a 15 day free trial is also offered and will work well enough for this purpose. Please purchase a license if you intend to use the...

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...
