Installing and maintaining Mac OS 9.1 was a complex process that could easily occupy you for several hours getting all its components right.
Classic Mac
From System 7’s Control Panels, through Mac OS X’s System Prefs, then System Preferences. And what happened in Ventura.
From the resource forks of Classic apps, to versioned and new-style bundles in 2001, document packages, then the incorporation of signatures and notarization tickets.
First released in 1993 to support colour printing, version 2.0 in 1995 brought fuller features and ICC support. Still going strong despite the decline of colour printing.
From its clean and spartan origins in Classic MacOS, the Finder has changed it metaphor, and now works more like a browser. Over 25 years of history.
From a desk accessory Choose Printer, to the Chooser, then Print Centre, Print & Fax, and Print & Scan, how printer support has changed.
At the heart of the first Macs, its support for Regions was unique, and it could replay drawing instructions in a Picture, the basis of its PICT file format. Then came Mac OS X with Quartz.
Introduced in System 7 in 1991, long before symbolic and hard links became available in Mac OS X, they’ve been revised and extended to bookmarks since.
How we crashed and burned with the best of them, from recovery disks in classic Mac OS, to unexpected restarts and hidden panic logs.
Extensions or INITs in Classic Mac OS required Conflict Catcher for their management. But they remain a vulnerability, and can’t be used with full boot security any more.
