MacOS – One Note alternative for Mac

EXACTLY that symptoms had my friend, he noticed it mostly in Excel an in the gaming - random freezing, first about a half second, later (1-2 months) became worse between 0,5-30 sec.

It was a HW problem. He bring his notebook to apple service, something (don't remember what) got changed and everything is OK now.

There is now a blog entry about Taking Screenshots in a Snap.

It's built into Mac OS.

• ⌘+⇧+3 captures the whole screen
• ⌘+⇧+4 captures a custom rectangle (click and drag over the screen region you want to capture)
• ⌘+⇧+4 then space captures a specific window (move the mouse cursor over the desired window, then click)

Press esc to cancel.

Screenshots are saved onto your Desktop and timestamped.

Holding control in addition to any of the sequences above causes the image to be copied instead of saved to the desktop.

By default the image format is png. However, you can change the format by typing in the Terminal:

defaults write com.apple.screencapture type image_format
killall SystemUIServer

Where image_format is one of jpg, tiff, pdf, png, bmp or pict (among others). If you omit the second line, you will need to log out and in again for the change to take effect.

The settings for the shortcuts in the system preferences are located at:
System Preferences → Keyboard → Keyboard Shortcuts → Screen Shots

The MacOS X application that enables screenshots is called Grab. It is located at /Applications/Utilities/Grab.app
