I used a registered copy of this program for a number of years and had it customized to do a specific job. When I migrated to a new Mac, the totally obnoxious registration procedure which checks an online database every time you install on a new computer gave me a string of messages that it couldn't find its server and wouldn't register my copy. The nicest thing I can say about this is, "blah." I have moved to Opal which is simpler, but faster and more reliable. It has a conventional registration procedure which won't lock you out of software you have paid for. I, personally, will have nothing more to do with this program or developer.

Why not contact Takashi Hamada and ask him to help you solve the problem?
The license is per user, and you can have a registered copy on more than one computer. You can't run multiple copies simultaneously with a single license, though. Sounds very fair.


OK. The latest update did accept my password and I am grateful for this because I have a lot of work in this format. Apologies for getting bent out of shape. I am still moving a lot of things to Opal, however.

Why isn't Tao's successor, Neo, mentioned here?

Neo has been mentioned, and there's a separate page for it here at Macupdate with the current beta 5. Both Tao and Neo share the same license.

After 5 years of productive use on several computers, I am suddenly unable to register this program on my new iMac 27. I just get an error message. Mind you, I have used these registration numbers on previous computers. Of course, the registration uses a "call home" system so registration depends on the developer staying in business and keeping that gimmick active. I have really a lot of stuff in this format and would, I guess, pay another ten bucks for a new license (not without a lot of complaining) if I had any confidence that buying a new license would solve my problem. The developer has been helpful before, but now is silent.

I am very concerned that TAO has been sold to some kind of reseller who is just trying to nab another $10 from registered users.

Your concern is unfounded. Tao was -and is- developed by Takashi Hamada.
The $10 is the price for a new license, which used to be more expensive. That license works for both Tao and NeO. There's no mention of upgrade pricing at all.
I've emailed Mr. Hamada twice, and both times received a response from him within a couple of days.


I have used Yojimbo for the last 2.5 years. prior to that I used all of the usual suspects, e.g. Circus Ponies Notebook, etc. etc.

Yojimbo does it all !

On the developer's website, a successor to TAO is announced:

A successor to TAO.

Coming soon."

Great, great outliner, complexity aside. But development seems to have been stopped, perhaps even abandoned. This is a shame. The latest version seems to have severe speed issues, taking several minutes or longer to open or to clip to. This had been one of the most promising and active applications up to 2007, the last time an version was released and their website was updated.

Version 1.8b

I didn't know if the developer would get or answer my message so I dug deeper and found the problem about the program hanging. Tao doesn't like font substitution supplied by Silk (Unsanity) that was enabled by default. Once that was disabled I have no more speed issues.

Excellent outliner! Not a very nice app but lots of excellent functionalities. Recommended.
But please, please release version 1.1, stop this never-ending beta development!

I started using a Macintosh with MORE(Which is now available for free and still works perfectly) a very long time ago (Yes, some of us are still alive). TAO is right on that track ; not trying to look nice, like OmniOutliner, but incredibly efficient.
It's not just a powerful outliner, it's certainly a great writing tool and I advise everyone not to be put off by the appearance of the app.
If you want to be able to write, reorganize your paragraphs, "fold" and "unfold" them, keep a general view of your work, TAO is for you.

I don't really care if the thing is in beta or not, although I agree it does seem silly to send users to version 1.0 as the last stable release.

The developer really needs to spend time on improving the interface, it's a mess of features, many of which I'm sure are great. I'd also be a little concerned about future plans to make a Windows version, that makes me wonder if a significantly improved interface is ever on the horizon. Too bad some of the other outliners don't take a lesson from some of TAO's power features.

I presently am writing a major research paper and practically live in this app. Having a rather nonlinear method of writing, this application fits my needs almost perfectly. I believe I have tried nearly every other outlining and nonlinear word processor out there for the mac and have not found anything else that comes close to this app in terms of features. That being said, the learning curve for some of the more advanced options is rather steep, and I was not thrilled about having to relearn some things when the author changed the way style sheets were handled a while ago.

I do not fully understand some of the complaints about the number of updates--I assume that they are coming from those who do not actually use TAO, at least not on a regular basis. I look forward to the regular updates and to seeing what features the author adds or refines with every release. Unfortunately, this did, at one point entail relearning aspects of the app as I mentioned above, but I have not had this experience for at least the last 25 releases. Nor have I had any problems with crashes since v1.1b18 or so.
