It is possible to use CMD instead of Control for keyboard shortcuts. Just follow these instructions while GIMP and X11 are closed : Create a .Xmodmap file in your home-folder containing the following: clear Mod2 clear control keycode 63 = Control_L keycode 67 = Control_L add control = Control_L

Then open X11 and change its preferences like this :

Now open GIMP. CMD+C and all the stuff should work.

If Time Machine gets disrupted for any reason during a backup (ie. hard drive unplugged, power failure) it seems to get stuck. Occasionally it gets stuck for reasons only known to Leopard. Its a known bug on the Apple discussion boards. What has worked for me is the following:1. ensure hard drive is powered on and connected to computer2. turn off time machine3. go to your backup volume, backups.backupd, "your computer name", and then select and trash "In Progress" or "Latest" (it will be the last one in your backup folder listing)4. turn Time Machine back on5. either wait for the next backup cycle, or what I do to be sure things are working right is force an immediate backup (control-click on TimeMachine, select "backup now").

To get Time Machine going again, you need to remove the errant files with the following steps: Ensure your backup device is turned on and connected to your computer (wirelessly or wired, it doesn't matter) Turn off Time Machine using the big button in Time Machine preferences. NOTE: I did not execute this step and was still able to fix Time Machine. Make sure the backup volume (which is just part of the backup drive) is mounted to your desktop/Finder. You may have to initiate (and subsequently cancel) a Time Machine backup process in order to see the drive on the desktop or in Finder. Access your backup volume in Finder (it should be named "Backup of your-computer-name..." or something similar) and double-click into the "Backups.backupdb" folder. Next, click into the "your-computer-name" folder. You should see a bunch of folders with dates. These are all the dates corresponding to days you ran a successful backup. At the bottom of the folder listing will be one or two things you need to move to the trash. You may see only one or both of these, but delete the file that starts with a date (it should be the date the backup failure started) and ends in ".inProgress." Also delete a file named "Latest" if it exists. Return to Time Machine preferences and turn Time Machine on. Remember, I was successful without performing this step. Initiate a backup using the Time Machine drop-down in the menu bar or wait until the next scheduled backup run. A final but important step, be patient. Time Machine may sit in "preparing" mode for a while. It's important to at least let it run for an hour or so to see if the process will continue actually writing files to your backup volume.

4. Though Mac OS X ships with a native PDF viewer, it doesn’t do much beyond letting you view a file’s contents. Skim is both a top-notch PDF reader and markup tool designed just for the Mac. Use Skim to preview the internal links of a document, add notes, highlight text and more. You can even use Skim to create presentations and control them-right inside the app-using an Apple Remote. As more corporate documents are transmitted every day as PDF documents, this is one app you can’t do without.
