This post is getting some attention due to the Mavericks release, but we are beyond v22 now, so please get the latest (not v22) for Mavericks.
You can download the latest build here.
Notably, the v23 update fixed a problem with the map, so it can find your location again.
This build is still in testing but we’re making it available to fix some bugs when f.lux is running on Mavericks.
Notable things: * We don’t leak megabuckets of RAM anymore * We use less CPU overall, compared with previous versions
