Yes, the latest version from the Apple App store DOES cost money .... HOWEVER ... the last free version of Xee - 2.2 - is still freely available, and DOES seem to still work on Mac OS X 10.9.5 ... at least it launched when I tested it, and all of the pieces appeared to be there ... I'm putting it BACK ... it is still of use. "The Last Free Version" is still good enough.
Thank You. I will remove it.
Homebrew - The missing package manager for OS X:
No, that's MacPorts.

Since Bean is no longer being developed, I'd recommend replacing it with Growly Write, which is excellent, small, and very actively supported by its developer Chris Mason, long ago project head for Microsoft Word 5 ("back when Word was fun," as he says).

Also, nothing wrong with FileZilla, but why a separate app installed when you can use the excellent FireFTP add-on for Firefox?

Hey, Hey! Only a Year Late ... Thank you for the GREAT Suggestion!
Thank you for the suggestions. I'll add them to this category in the next few edits.

I Just found out about this Mac utility app called Magician. It has many functions-various cleaning utils,duplicate finder,memory optimization,left and right fan speed adjustment,app uninstaller, and more.

I was impressed by what this program can do, definitely worth giving it a look to compare it to CLeanMyMac and others...

Hi JTAlsman, I've added Magician to the list. Thank you for brining it to light! Alec
