This app, like its companions in this category, namely, What's Keeping Me?, or Sloth, or Lock-unmatic, may NOT succeed in finding out why a stubborn external Firewire volume will not eject.

I don't' suppose that this is any fault of these applications, but due to some mysteries in the Mac OS that neither of them have figured out yet.

So, don't expect a miracle. You may still have to Force Eject a volume to get it off your desktop. Hopefully, no harm occurs.

Aargl,

Thanks for the heads-up! I've updated the listing accordingly.

Really indispensable! Especially if you have several system partitions or are in the way to transfer data between those partitions: when trying to unmount a volume the system says it can't, there's probably some process from your old system partition running from there instead of your actual system.
What's Open lets you locate and quit such app or process. That's all and that's great! :-)

If you answer an option in the poll that has a blank in it please fill in the blank by e-mailing me or posting here with your idea/request. Development is user driven. Your input dictates my development.

After looking at the poll results and answering some e-mail super-user kill will be available in the next release. Thanks to all who discussed it with me.

For those who didn't understand the poll, WhatsOpen currently will not kill a process as the super user. This means you cannot kill anything your user is not the owner of. In the next release this behavior will be changed so if you kill an application when super user mode is enabled it will kill the application as the super user.

Wow! As stated, almost too much information. But I see features that folks here have asked about. That is service, especially for a free app. And yes, it's a free app that I'll be able to get a lot of use from.

Thank You!

bomb app.

forming, quite possibly into The app i ignite when managing unruly programs. i can't decide if the developer is giving my little brain too much info. ;) i know it's for a little different task, but i like it for a few different reasons.

i mean, this is the most thorough application informant i've ever seen. it tells me so much about wWhat's oOpen that i wanna shut all my programs down and regulate what they do with my junk.

i mean, shoot, stickies had like 20-30 things open and ill i had that punk doing was acting as a background.

and yeah, the processor allocation per app is what's really important performance-wise, i know. but this serves up the info that cues me into all sorts of directions.

and the developer is behind it 100%. it should be a prime competitor real soon. maybe number 2-3 on my list, which is really good.

tightening up the look/feel is big for me. i hate booty lookin apps. i want quartz in every empty box and field! probably barf, but those kinda options rule. like what homeboy did at unsanity, adding quartz to all of my gui menu drop downs! that's what the mac community seems like it would love.

download this. but listen you pair-downers. you know. you cats who have one app running and every-single bell and whistle turned off - much respect - more like performance-tweakers. i'd stay clear as all hell from this app. you're gunna get so much info about stuff you didn't know was cracked under the hood that you might miss some ZZZs at night or need to up that riddlin prescip. ignorance is bliss . ;)

gave it 4 below cuz i think there's still room for a little more tinkerability.

Thanks for the kind words. I've been digging through the sysctl() function set to try and figure out how to grab the per-program cpu utilization. Not having a lot of luck figuring out out as most of the values I look at turn out 0 even though there clearly is usage on the test programs...

Anyone out there know what MIB queries / response fields I'd find this type of data in while using a sysctl() call?

Ok, I've found how to obtain the CPU statistic information on processes. This requires root level access to the system, but that isn't a problem since that level of access is already granted if you enable full file listings. I will work this into a new release in the near future.

Strange, I tried WhatsOpen and I got a kernal panic. Dropping files from finder does not work.

What do you mean by "dropping files from finder"? Are you attempting to drop a file from the finder and see what has it open? That is a feature I never considered...
