I am in a similar situation, I lost my Mac air and want to reinstall on my new one but nobody seems to be able to do this for me, I have been on line to the support service who to be fair were helpful but no-one has yet come up with a definitive way forward. I have now suggested cancelling my existing one on the old laptop and buying the same thing again although I still have 9 months remaining on the old licence. All details of my licence are on the old computer which isn't working so no access. Any suggestions would be helpful. I am thinking maybe return laptop to Apple and ask them to sort it. Your thoughts would be appreciated.
Thanks for reading.
