How to Kill an Application

Some Mac applications are running like background services. For example Growl, EverNote and Dropbox. The only interface is at top right menu bar. The problem is that sometimes their interface or context menu are not available; as a result, there is no way to quit the application. My Dropbox has this problem after a while.

I tried to use Mac Force Quit... from Apple menu, but I could not find them. Fortunately, there is an alternative way to do it. Here are the steps to do:

• Open Terminal
• Type command: ps -A |grep Drop. You will see Dropbox application process id(pid), time and application location.
• Type the command to kill the Dropbox: kill [pid].

All those ps and kill commands are most commonly used UNIX commands.

Epson Printer Update 2.3.1

Todya's update is for Epson Printer, which is specific for the printer I have purchased and installed. The link in the update description does point to Apple's support web site with generic description and long list of printers.

Starting today, I'll do clean update. That means I'll clean my trash first, then restart my OS. Record the space I have before the update. Run the update, clean trash again. Finally restart Mac OS, and record the space after the update. Before I run several applications or browsers during my updates. I think that my calculations in those cases may not accurate. Some cache or files unrelated to the updates may be cleaned during the update. By doing the clean update, I think the disk space before and after should be more accurate.

The following is the summary of space difference between before and after the update:

Command: df -lak	Used(Kilobytes in 1024-blocks)
Before	...3,328
After	...6,976
