If you are using the latest version of the terrible, slow, web-based remote support application LogMeIn free for mac then all you need to do to remove it is go to “Applications” -> LogMeIn -> and double click on the LogMeInUninstaller.  When the Uninstaller comes up, just click on “Yes” to uninstall it.

If you are using an older version of LogMeIn then you will need to go to the following directory:

/Library/Application Support/LogMeIn/

run uninstaller.command

This will open up a terminal and prompt you for your Mac username and password and then uninstall LogMeIn from your system.

Either way, you need to reboot your system after both methods.

sudo gedit /etc/apt/sources.list
Add these two Lines:
deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntujaunty main
deb-src http://ppa.launchpad.net/chromium-daily/ppa/ubuntujaunty main
btw replace jaunty with intrepid if your still using that.

Now add the GPG Key:
sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 5a9bf3bb4e5e17b5

sudo apt-get update ; sudo apt-get install chromium-browser

Now once installed Go to Applications->Internet->Chromium Browser and right click it, add to Desktop
Right click the new chromium icon and go into properties and add the following where it says command:
chromium-browser %U –enable-plugins

Note: You’ll of course need flash installed for firefox first, to install that:
sudo apt-get install flashplugin-installer

Now lets install flash before we launch this baby:
sudo cp /usr/lib/firefox/plugins/flashplugin-alternative.so /usr/lib/chromium-browser/plugins/flashplugin.so

Now click the newly made icon and head over to Youtube or Hulu

Everybody knows about some of these boot key combinations, but some of the more obscure combinations have been long forgotten (like how many of us have a Quadra AV and use a TV as a monitor!) – Check these out, you may need one of them someday!

  1. •C : Forces most Macs to boot from the CD-Rom drive instead of the internal hard drive. Only works with Apple ROM drives and with bootable CD discs.
  2. •D : Forces the first internal hard drive to be the startup disk.
  3. •N : Netboot (New World ROM machines only) – Looks for BOOTP or TFTP Server on the network to boot from.
  4. •R : Forces PowerBooks to reset their screen to default size (helpful if you’ve been hooked up to an external montior or projector!)
  5. •T : Target Disk Mode (FireWire) – Puts machines with built-in FireWire into target Disk mode so a system attached with a FireWire cable will have that device show up as a hard drive on their system. Very useful for PowerBooks!
  6. •Mouse Button Held Down : Ejects any mounted removable media.
  7. •Shift : Disables all extensions (Mac OS 7-9), or disables Login items when using Mac OS X 10.1.3 or later. Also works when booting Classic mode up just like you were using the OS natively.
  8. •Option : When using an Open Firmware “New World ROM” capable system, the System Picker will appear and query all mounted devices for bootable systems, returning a list of drives & what OS they have on them. On “Old World” systems the machine will simply boot into it’s default OS without any Finder windows open.
  9. •Space bar : Brings up Apple’s Extension Manager (or Casady & Greene’s Conflict Catcher, if installed) up at startup to allow you to modify your extension set.
  10. •Command-V : Boots Mac OS X into “Verbose Mode”, reporting every console message generated during startup. Really shows what’s going on behind the scenes with your machine on startup!
  11. •Command-S : Boots Mac OS X into “Single User Mode” – helpful to fix problems with Mac OS X, if necessary.
  12. •Command-Option : Rebuilds the Desktop (Mac OS 7-9).
  13. •Command-Option-P-R : Erases PRAM if held down immediately after startup tone. Your machine will chime when it’s erased the PRAM, most people will hold this combination for a total of 3 chimes to really flush the PRAM out.
  14. •Command-Option-N-V : Erases NVRAM (Non-Volatile RAM). Used with later Power Macintosh systems mostly.
  15. •Command-Option-O-F : Boots the machine into Open Firmware (New World ROM systems only).
  16. •Command-Option-Shift-Delete : Forces your Mac to startup from its internal CD-ROM drive or an external hard drive. Very helpful if you have a 3rd party CD-ROM drive that is not an Apple ROM device.
  17. •Command-Option-Shift-Delete-#(where #= a SCSI DEVICE ID) : Boot from a specific SCSI device, if you have your 3rd party CD-ROM drive set to SCSI ID 3, you would press “3″ as the # in the combination

And, the obscure ones :>) Older computers only, on some.

  1. •Command-Option-I : Forces the Mac to read the disc as an ISO-9000 formatted disk
  2. •Command : Boots with Virtual Memory turned off.
  3. •Command-Option-T-V : Forces Quadra AV machines to use TV as a monitor.
  4. •Command-Option-X-O : Forces the Mac Classic to boot from ROM.
  5. •Command-Option-A-V : Forces an AV monitor to be recognized correctly.

Let me guess, you can’t delete a file from the Trash bin on your Mac. When you try to ‘Empty Trash’ you get an error message saying ‘The operation cannot be completed because the file is locked’. This is a fairly common problem and one which almost every Mac user encounters at some point. I will show you how to delete the file from your system.

Deleting a file from Trash

Some Common errors upon attempting to Empty Trash include: “The operation cannot be completed because the file is locked” or “The operation cannot be completed because the item is in use”.

  1. 1.Drag the file from your Trash bin to the Desktop.
  2. 2.Launch a Terminal Go > Utilities > Terminal and type the following into the terminal window leaving a space after f:
  3. 3.cd ~/.Trash && sudo rm -rf
  4. 4.Drag the file from your Desktop to the terminal window and then press Enter
  5. 5.Enter your password when prompted and press Enter

6.    If everything goes as planned the file should now be deleted from your system.

Snap is a quick way to resize your open windows.  All you have to do is drag them to the edges of your screen.

Depending on where you drag a window, you can make it expand vertically, take up the entire screen, or appear to the side of another window. Snap makes it easy to read, organize, and compare your windows.  This is just one of the new features in Windows 7.  Make sure you read my other tutorials related to the new features of Windows 7.

Let me guess, You have a windows machine running in VMWare Fusion.   Sometimes when you reboot the vm, it hangs while shutting down or rebooting.  When you look at t he VMWare menu you only see the following options:

If you have tried everything and can’t seem to shutdown or reboot  your vm then there’s one more thing you can do, go to the VMWare menu above and hold down the option key.  Once you do this you will see the following options:

You now can actually power off the machine or reset it.

Need to clean up disk space in Ubuntu? Try the following commands from a gnome terminal:

sudo apt-get autoremove – This command removes any unused dependencies from the Ubuntu system.

sudo apt-get clean – This command removes all cached package files.i

These commands won’t hurt your system. On a system that’s been updated a couple of times, you can free-up as much as a gigabyte using these commands.  You can do a before and after using the following command:

df -k
