Ironically, until now there are Mac-programs that are not compatible with a dark regime OS X Yosemite. In practice, this means that the menu bar instead of the program status icon will be gaping black hole that is not only ugly, but also completely uninformative. If a would-be developer still can not provide for a light version of the status icons, and you use extremely dark mode, here's a special council on OS X, how to manually lighten the "invisible" icon.
For example, consider MacUpdate applicationWhich is equipped with only black status icon, designed for normal light mode OS X. The whole procedure can be divided into seven steps.
Step 1. In the Finder, open the folder "Applications" and locate the program with the problem of the status icon (in this example, MacUpdate).
Step 2. Right Click on the application icon, select the shortcut menu "Show Package Contents".
Step 3. Once inside the program, navigate to Contents / Resources folder.
Step 4. Find the very icon that is clearly visible in the menu bar in the normal mode and is invisible in the dark. This is often one or more image files to the Status word in the name. In the example program is MacUpdate two PNG-images: Status.png and [email protected] (for normal and retina displays respectively).
Step 5. Copy these files, for example, on the desktop and open them in the "View".
Step 6. By selecting one of the pictures, click ⌥⌘C keys to bring up the color settings window Inspector. In the upper area (where a histogram levels) look at the two extreme slider. Simply swap them - and the color image is inverted: from the dark it will turn into light.
Step 7. Repeat the same operation for the other icons and save them. Then transfer files back into the Resources folder (you may need to enter an administrator password) and restart the program.
Now the previously invisible icon should be perfectly visible, combined with the rest of the status icons in the menu bar:
