Regrettably, the original source code has been lost

The hard drive containing the code recently failed. I hooked up the backup drive I was using at the time this was written and found it had silently broken itself while disconnected. As this was more or less a small hobby app project and I haven't had the time to maintain it, I don't foresee any rewrite occurring. Apologies to people with new laptops that aren't supported by the app. Existing files will remain hosted here for the future.

I realize the post below this happily mentioned a bug fix would occur in 1.7 for memory related crashes, and I wish I could say it was written but never got pushed out, but it wasn't. I ran out of time to work on the project and sadly it just got dropped at that time. In total, I've received maybe 10-15 crash reports over the lifetime of the app and have run it on all my systems 24/7 since I wrote it without any crashes myself so I do feel the issue is fairly isolated. Once again, apologies for the abrupt farewell.

There appears to be a memory related bug in 1.6-1.6.2. I've received a few crash reports that all look identical. This problem should be addressed in 1.7 which will likely be out this weekend. Sorry for the inconvenience.

• Power-state based GPU switching now for the 9600/9400. Please note, it is entirely possible that the 9600GT remains powered after a switch if any applications remain open. Through testing it seems to stay powered according to iStat, though it is unclear whether or not it powers down after applications are relaunched.
• Growl will now notify a list of applications that are keeping the 330M running on 2010 MBPs when switching to battery power.
• GPUInfoMenu should no longer cause screen savers to flicker periodically while on battery power with the use integrated graphics on battery option selected.
• By request, monochrome icons for the status bar are now available in a small preferences sub menu. Icons in the menu itself will remain in color.
• And under the hood, a significant reorganization of the source code to make it more manageable.
• ---The lag of the menu opening when the 330M is running has not yet been resolved in this release.

• GPUInfoMenu can now toggle between dynamic GPU switching modes and the integrated graphics on new Core i5/i7 MacBook Pros. This functionality is triggered by a menu item (off by default). There is a single toggle that switches the GPU to Intel graphics when the laptop switches to battery power and back to standard dynamic switching when on AC Power. Toggling the menu item back off or quitting the application will also return the computer to standard dynamic switching. This functionality has -not- been tested on 9400M/9600GT systems and probably will function oddly.
• Update: This feature was buggy and has been patched out with 1.5.2. Look for it in 1.6. The population of the list of processes is now an asynchronous task and should not block the creation of the menu; however, at this time I have yet to be able to get the menu to update while open (though I expect to nail it down soon), so you may need to close and re-open the menu.
• Secondary monitors will now show in the process list.

• Got a chance to the application on a few macs, and it seems to be stable (successfully identifies my GMA 950 as Intel on my Mac Mini and works on some associates’ GPU-switching laptops). I’ve also addressed an issue where the About window would not appear on top of other windows. Looks like it's still not going on top of other windows...
• If anyone has any feature requests/suggestions, feel free to submit them. I’m looking for various ways to get some more information about triggering the GPU switching functionality, or at the least, toggling the setting that exists in EnergySaver. If anyone thinks Growl is useful, let me know and I’ll look at getting that in, though I figure it’s already in the menubar so it’s pretty clear what’s going on.

• Minor robustness enhancements.

• Monitors the system for GPU changes, immediately updating the icon when graphics switching takes place
• Listens for CGDisplayRegisterReconfiguration so that does not need to poll for changes - updates only when needed
• Handles registering/unregistering startup behavior
• Auto updates with Sparkle
