This is my first try at a GeekTool desktop.
I'm not sure if these geeklets work on all macs or not, but tentatively these are for OSX Mavericks and up.
My desktop is minimalist-ish. It has some time and date elements, these battery geeklets, and a "To do" section that reads a "todo.txt" containing that exact info.
To check if the battery geeklets work on your computer, enter this in terminal:
pmset -g batt
If you get a response which includes battery data in these kinds of formats:
Now drawing from 'Battery Power' -InternalBattery-0 47%; discharging; 2:46 remaining Now drawing from 'AC Power' -InternalBattery-0 46%; charging; (no estimate)
then the geeklets should work fine. When you place them, place them under each other.
To do geeklet
The "To do" geeklet reads a "todo.txt" file on your computer. To edit the location of this file, open the script and edit this line:
to suit your needs.
If all works well then you get something like the picture I uploaded. Change the fonts and style, etc.
These are part of my whole desktop design for my MacBook Pro. It's not really that tough to recreate this desktop. If I update this, then I will reupload these geeklets.
