Cut paste

Copy, Cut & Paste doesn't work quite the same way as it does on Windows.

Here are a couple of links to pages with lists of keyboard shorcuts or special programs that add that functionality, and some cost money to get.

• Cut with Drag & Drop
• OS X Keyboard shortcuts
• Total Finder
• MacRumors Guides for OS X

 

OPTION is located between CMD and CTRL and sometimes referred to as ALT.

Resizing a drive is done in disk utility. Go to Spotlight (magnifying glass at upper right of screen). Type disk ut and by the time you hit t, Disk Utility should already be highlighted in the search results. Click on it and you will see macintosh hd show up as one of the drives you can work with. Be careful. From Disk Utility, it is possible to do a lot of damage so be careful and take your time.

I'm curious, why are you resizing a partition? If you want to run windows in parallels, you do realize that can be done without a separate windows partition, don't you? Windows or Linux or whatever OS you want to tinker with can run out of a file on Macintosh HD. I normally keep one partition on my Macs.
