There’s a quick update for  Default Folder X today – version 4.4.12 fixes a nasty bug that could cause Open and Save As dialogs to hang in DVD Player, Adobe Bridge, Flash, Vector Magic and other applications. Please install the update now.

And if you’re seeing a little file named “/-” constantly appearing at the root level of your hard disk, update your copy of Default Folder X to fix that too. The problem is actually due to a bug in the “codesign” utility that’s built into Mac OS 10.7 – I submitted a bug report to Apple and they replied that they know about it and are working on a fix. In the meantime, version 4.4.11 or higher of Default Folder X avoids the bug, so once you update, you shouldn’t see that file anymore.

Version 4.4.10 of Default Folder X is now up on the site, sporting compatibility with the latest developer release of Mac OS 10.8 (Mountain Lion). This includes being properly code signed so Mountain Lion’s new “Gatekeeper” will allow you to install it when you have the default setting of “Mac App Store and identified developers” turned on.

Other improvements include an increase in performance – two bottlenecks that were causing long pauses when refreshing file dialogs have been eliminated – and corrections for compatibility with Firefox 11 and Mathematica. Default Folder X’s OpenMeta support has also gotten some love, bringing back autocompletion of tags that you’ve entered using Leap and Yep (this was lost when Ironic Software modified them to meet Mac App Store requirements), and addressing a problem when tagging files inside of Adobe InDesign.

Round that out with some additional bug fixes and performance tweaks and you’ve got a worthwhile (and free) update. Enjoy!

It started as a request from a user who wanted a color App Tamer icon so he could pick it out more easily amongst all the icons in his menubar. But being an obsessive developer, I wondered if I couldn’t make that colored icon more useful too. Just last month, Adam Engst wrote an article in TidBITS detailing how iCloud had chewed up the battery in his MacBook Air before he could catch it. It was using 100% of one CPU trying to sync his bookmarks even though WiFi was turned off. If he’d known that the CPU usage was through the roof when it happened, he could have stopped it and had enough battery for his whole plane flight. Instead, he had to read the in-flight magazine and gaze out the window instead of finishing the book he was writing.

So what if I could blend those two purposes? I tweaked App Tamer to colorize its icon based on CPU usage, like this (I can’t believe I just uploaded an animated gif for this – talk about retro…):

It’s subtle for low CPU values – you might want to take note of it, but it’s no crisis you need to be alerted about. But as CPU load increases, it gets brighter until it really gets your attention at 100%. If there’s something that’s sucking down all of your processing power, you want to know.

It’s a fairly minor feature, but I now appreciate it being right there all the time. I hate having to plug in my MacBook Pro in the coffee shop just because something decided it had to do a bunch of useless work in the background while I was answering emails! So grab a copy of App Tamer 1.2 and check it out – I’m pretty pleased with it. Be aware that if it’s not your thing, you can easily turn it off with a trip to your App Tamer preferences.

Oh, and also new in version 1.2 is support for Firefox 11 and a fix for some troubles App Tamer was having when the system didn’t notify it about an application launching or quitting.

Details and download links are on the What’s New in App Tamer page.

I’ve had requests from a number of people asking for a hotkey to pop up Default Folder X’s menus under the mouse. That way you don’t have to go all the way up to the menubar to get to your Favorite and Recent folders. Default Folder X doesn’t currently have a keyboard shortcut for this, but you can make one easily with any macro utility that supports AppleScript. Keyboard Maestro is one example.

Just configure your macro program to run this AppleScript:

    with timeout of 0 seconds
        ignoring application responses
            tell application "Default Folder X"
                ShowMenu
            end tell
        end ignoring
    end timeout

That’s all there is to it!  Thanks to Scott Mintzer for jogging my memory on this.
