Opal: Easy notes and organizing

An Old Favorite is Back!

The new outliner by the creator of the award-winning Acta is now available (in both English and Japanese)!

Designer David Dunham says, “Back in 1986, I released an outliner called Acta. It continues to run fine under Classic. But Intel-based Macintoshes have no Classic, and Acta fans were worried that they would be forced to stop using it. So I created a modern successor, Opal™.

“Opal retains the fluid ease of use of Acta, but is up to date with Mac OS X standards.” Universal logo

What Others Say

“Opal, just like its Acta ancestor, is small, fast, friendly, effective and reliable. I’m using it to organize and manage everything from daily tasks to projects, and it works as a simple calendar/tickler and diary. I like to keep my main organizing outline on the desktop next to the hard drive, where I can instantly pop it open, review tasks and update information.” — Ric Ford

“Opal is a full-featured, flexible and most importantly easy to use outliner. … there’s so much I write and plan, that will be facilitated by using this product.” — Harry Babad, MacCompanion

“Thank you for reviving this nifty software. This is what I have been waiting for since I switched to OS X.” — Shigeaki Nishina

“Opal is a simple, flexible and useful outlining application which I suspect some people will end up not being able to live without.” — Chris Howard, Apple Matters

“I have refused to migrate to the Intel-based Macs, primarily because they won’t run Classic, and without Classic I can’t use Acta.” — Steve Eichel
