Using an Airport Extreme or Time Capsule to make Time Machine backups on your network is very convenient.  But I found that once that machine is gone, I could not delete the old TM backup.  I kept getting this error:

“The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again.”

After trying to change the permissions without success, I found this terminal command works:

sudo rm -rf <Path to the TM backup file>

Hint: to easily type the path to the TM backup file just drag it into the terminal window.

Hope this helps anyone else out there.

This happened when my AD account was deleted and then re-established using the same username.


  1. Login to the affected profile
  2. Run Terminal
    1. run “id -u” to get the new user id
    2. run “id -g” to get the new group id
    3. run “sudo chown -R <the userid found in sub-step 1 above>:<the groupid found in sub-step 1 above> /Users/<username>
    4. run “sudo chown -R <the userid found in sub-step 1 above>:<the groupid found in sub-step 1 above> ~/Library
  3. Reboot

Macbook Air was draining battery while it was supposed to be sleeping.  When I ran a “pmset -g” in terminal it told me “sleep prevented by AddressBookSourceSync”.  I don’t use the Apple Contacts, but I do use google.  So I went into Internet Account settings and removed the google account.

This problem always seems to pop up when there is a power outage or I am installing an new HP printer.  I believe it is trying to load the driver/software usb disk, which is not formatted for Mac.  Neither un-pugging/plugging the USB nor turning the printer on/off worked.  The solution is to unplug the usb, then turn the printer on and wait for it to fully turn on.  So both the computer and the printer are fully on.  Then plug the USB in.  Presto!

Open Finder, Disk Utility and Open Terminal.  In terminal type “dd if=” and then drag the iso from Finder to the terminal window, that will fill in the path.  Then space and type “of=” and drag the mounted usb partition from finder to the Terminal windows to again fill the path.  Then in your Disk Utility, Unmount the USB Partition (Unmount, NOT Eject).  Then back in your terminal window, hit enter.  Done.

So your command should look like this “dd if=/Users/user/Downloads/SW_DVD5_Win_Pro_7w_SP1.ISO of=/Volumes/USB”
