Free screen capture software for mac

Change Screen Capture Type is a small AppleScript application that allows you to easily change the default screen capture type in Mac OS X 10.4 or later.

The captured images type may be changed to any of the following types: png, jpg, tiff, pdf, pict, jp2, bmp, gif, psd, sgi or tga.

Completly freeware.

ScreenCapture X enables you to capture a window, a selection of the screen or the entire screen without having to remember key commands anymore.

Just click the appropriate button then click the Capture Screen button. It will save it as a JPEG (numbered sequentially) to your Desktop. Simple, huh?

Tiger saves screen captures as PNG files, so using ScreenCaptureX will allow you to skip the step of saving them as JPEGs.

By default, the System generates screen capture PICT files at startup disks root level as SimpleText (TeachText) graphics.

ScreenCapture2PhotoshopPICT is an AppleScript that converts all screen captures found at the startup disks root level to Photoshop PICT format.

Once in a while, I need to take a picture of the screen with a menu pulled down, in order to document one of my shareware programs. If I did this every day, I suppose I wouldnt mind paying for a screen capture program with all the bells and whistles, but as it is, I resist. Years ago, there was a tiny freeware extension called StillDown, by Gregory M. Robbins, that enabled command-shift-3 screen shots with menus pulled down. But StillDown doesnt work with Mac OS 8. Therefore, I decided to write a new free bare-bones menu snapshot program: MenuCapture.
In Mac OS 8.1 and later, if you pull down a menu with a click rather than a click-and-hold, you can snap its picture without the aid of MenuCapture. Thats why MenuCapture is on the Obsolete page.
To install MenuCapture, drop it in your Control Panels folder and reboot.
To use MenuCapture, open the MenuCapture control panel and click the "Enable" checkbox. Then pull down a menu, and press the keys command, shift, and control simultaneously. What happens next depends on what version of the system you are running. With System 7.6 or later, the cursor turns into a cross-hair; let up the mouse button, then click and drag to select a rectangle to be copied to the clipboard. With earlier systems, a snapshot of the whole screen is saved as a picture file on your disk.
The actual picture-taking is done by the built-in screen capture FKEYs: FKEY 4 in the case of System 7.6 and later, FKEY 3 in the case of older software that did not have FKEY 4.
Enhancements:
- Makes it more obvious how to capture a contextual menu, by ensuring that the cursor changes to a cross-hair.
- I also attempted to clarify the text in the control panel.

Screen Watchdog can watch an area on the screen the user specifies and play a sound or execute an Applescript the user has choosen when the screen changes.

Completly freeware for personal use.

Full Screen Safari is a small AppleScript that hides the Dock and expands the frontmost browser window to fill the entire screen.

Completly freeware.
