I changed the HDD of a Macbook with OS X Yosemite by taking the HDD out of the computer and making a byte-by-byte copy with dd on Linux. Now MS Word refuses to start saying the copy isn't licensed. It seems to calculate a checksum over the license key and hardware serial numbers and fail due to the change of the HDD.

I have both HDDs at hand and could restore the old installation by putting in the old HDD. How can I prepare MS Word (license) to survive the HDD change?


You need to copy


from the old machine to the new one. Make sure you put it into the exact same location.

  • That doesn't work - how could it the old and the new drive have been copied byte-by-byte, moving files can't change anything. May 1 '15 at 11:35
