The tools OmniFocus offers, synchronization, iPhone client, reviewing, outlining, focusing, filtering and sorting, and overall usability make this app the best all-around solution for managing large, complex collections of tasks and projects.

I've tried both Things and THL; both are nice apps, well-suited for simple task management. But when trying to deal with *everything* going on in my busy life, all the other apps simply couldn't manage and spiraled out of control.

OmniFocus, on the other hand, gives me the tools to stay on top of this mountain of projects. Thank you, Omni Group!

I've used LaunchBar for a couple years now, taking a few breaks along the way to try out the competition. But I always come back to LaunchBar. Others may have even more features, but LaunchBar does nearly as much and with a much greater degree of elegance and simplicity. It's proven to be a rock-solid, reliable companion on my MacBook Pro. I love it.

TextMate has a very vocal following. I was convinced to try TextMate on a project for a few months last year and I grew to like it. I even bought a license.

But after extensive comparisons, I ultimately returned to BBEdit and concluded that it is still the better tool. I haven't seriously used TextMate since.

First of all, BBEdit follows long-standing Mac paradigms: text dragged onto BBEdit's icon opens in a new window, events trigger on mouse up rather than mouse down, renamed open files are automatically updated, text selection feels more natural, undo is chunked rather than performed on each individual character, etc.

Second, BBEdit provides several features that are amazingly absent in TextMate: split window editing, tabbed editing OUTSIDE of a project, multi-file search and replace OUTSIDE of a project, ability to open very large files (>250MB) and function reliably, spell checking by right-clicking on a word, single click selection of multiple lines, ability to assign a key combination to just about anything, complete AppleScript support (so the application itself can be scripted not just the text in a document), GUI file comparison showing character-level differences, synchronized scrolling between multiple windows, optional display of all non-printing characters, optional display of tab stops, search for the current selection with a single key press, double-click to balance, named markers (a.k.a. bookmarks), ability to jump to previous insertion points, Text Factories, etc.

And third, BBEdit's implementation of key features is often superior to TextMate's: code folding triggers on mouse up rather than mouse down, opening and closing fold markers are easier to distinguish, BBEdit allows multiple arbitrary folds on the SAME line (useful for very long lines of code), folded blocks can be selected/copied/pasted/dragged, clippings auto-completion is easier to use and doesn't require remembering obscure strings coupled with a tab to complete, BBEdit's tabbed-editing makes it easier to work with more open documents (easily handles 40 or more) and with longer filenames because "tabs" are displayed vertically rather than horizontally, tabbed documents can be dragged between multiple windows, ALL unused features can be turned off (resulting in an interface I personally find less cluttered and easier to navigate), BBEdit's File Groups makes it easier to work with multiple projects simultaneously because they are displayed in separate windows, more fully-featured grep search/replace, visual feedback when looping on a quick search, line numbers are NOT part of the text view and don't scroll out of view when scrolling horizontally, a better organized and more fully-featured function menu, BBAutoComplete (a free BBEdit plug-in) allows arbitrary word completion based on text in the current document or in all open documents or from the system's spelling dictionary, etc.

Of course, TextMate has a few nice features: more control over syntax coloring and style, excellent scope system, slightly nicer column editing. But I can easily live without those considering all the advantages of BBEdit.

The bottom line is TextMate is a nice editor and it's less expensive than BBEdit, but it's also significantly less capable. If I used TextMate, I'd still need BBEdit to have all the capabilities I want. However, I could easily live entirely in BBEdit and never even miss TextMate. If you make your living writing code or working with text, and you want the best tool available on the Mac platform, the choice is clear: BBEdit.

I've been looking closely at some of the interesting features offered in other apps of this kind (like some of the new things in SOHO Notes 6), and I hope Yojimbo continues to grow.

But what keeps me coming back to Yojimbo is its sheer simplicity, elegance, and reliability. Yojimbo might not have some of those extra features, but its very good at what it does. And all the features in the world are useless if the app isn't reliable.

Just installed 9.0.28 on a MacBook Pro and had no problems. Installed fine, seems to be working properly, and did not require any permissions to be repaired (as other posters have suggested).
