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?
