When copying files to a Networked Attached Storage (NAS) like an Airport Express Extreme, do you get the error file in use?
A very simple way is to disconnect from the disk, then reconnect using AFP.
From the Finder under the GO menu choose Connect to Server. Or you can also press Command K.
Then type AFP://SERVER or IP
Now try your copy and it should be fine.
We just upgraded our Mac Parallels to version 10 and everything seemed ok. But when trying to boot the Windows 7 image it hangs and displays winlogon.exe, Bad Image.
The Monkey fixed this first by running Mac’s built in Disk Utility and running a Repair Disk Permissions.
That helped to actually boot into Windows but we were still getting an error regarding KbdPrlUS.dll.
After many Internet searches that turned up nothing we figured this DLL was not part of a standard Microsoft Windows install but installed but Mac Parallels software.
So we did a search for KbdPrlUS.dll and found 2 place it existed. We deleted both.
Then restarted and all error messages were gone. We then finished the Parallels install by installing Coherence software. You can tell if this is not installed if there is a yellow warning symbol 
in the Parallels tool bar. 
Be aware that after you click the warning symbol and choose install, you may have to go to your CD drive in Windows and then clicking Install. After a restart Windows should be running in full Coherence mode and blend in with your Mac.
Did you know that if you COMMAND click on any icon in your dock it will open directly in Finder?
If you CMD click an app it will open it’s location in the Application folder.
If you CMD click a folder like your Documents or Download folder it will open that folder immediately in Finder. Very quick and easy with one click.
Sometimes Android apps can display annoying notifications in the top part of the screen and theres no apparent way to disable them. If you have Android 4.1 or later it’s actually easy to do.
