At McKinsey in the 1990s, we used ‘Solo’ presentation software to make slides. It was far ahead of its time (before PowerPoint became the standard). It had a very advanced template engine that enabled you to recreate charts in the McKinsey style. The software required some skill, and charts were usually created by professional graphics designers who took hand-drawn charts as an input. Back then, Solo would run on Macs only. Which was the reason that McKinsey issued Macbooks to their staff at the end of the 1990s, so that consultants could edit (and create) their own slides if they had to.
Ultimately PowerPoint was the end of Solo. Not because of its capabilities, but because McKinsey’s clients would have this installed on their machines, and these clients wanted to edit slides themselves. And with the advent of PowerPoint, the slide format became less consistent in McKinsey. (Both the result of a less sophisticated template library, and the reduced influence of professional graphics designers to create the slides).
I checked this morning, and Solo is still around, here is the web site: https://www.axoninc.com/. Support has ended in 2020 though. I tried installing the demo on Mac, but failed. The PowerPC engine no longer works. It does work on Windows 10 though, but I had to click a button 587 times because the license of the trial version expired 587 days ago (on 7 February 2022). Those clicks were rewarded with some good memories though, I have added some screen shots.
