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...

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 UNIX 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 boot a Mac OS X installer without a DVD drive or an USB stick?

So you got a Mac OS X installer disk image (.iso, .toast, .cdr, .dmg) and would like to boot your PowerPC (G3, G4, G5) from it in order to install OSX, but unfortunately, the DVD drive on your old Mac is broken, missing or you're simply out of DVD discs? You instead went ahead and proceeded to boot your PowerPC Mac from an USB stick but it didn't work because the old Mac's USB ports are broken or the Open Firmware command fails for...

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, which...

How to install Classic Environment (Mac OS 9.2.2) on top of Mac OS X

How to manually install Classic Environment using a Mac OS 9.2.2 System Folder I suggest that you grab the first download "Generic Classic Environment for Mac OS X 10.4 Tiger" here because it fits most needs, but feel free to try another Mac OS 9.2.2 System Folder if you want.  Download it on your Mac OS X 10.4 (or earlier) computer and expand the .sit archive.  Then drag the resulting System Folder to the Mac's hard...

How to recombine (join) split files (.001, .002...) into a single ZIP archive under Windows or OSX

Before you read any further: If your file does NOT EXACTLY END WITH .001, .002, etc... (e.g. ASD_3S152.001.dmg) then you need to jump to the split Disk Utility disk image section. When you come across split files that end with sequential numbers (e.g. .001, .002, etc...), before you can use the file, you first need to join the split files together into a single, whole file.  A split ZIP file could look like this, for...
