Failed updates after new HD installes
I live in South Africa, and use a MacBook Pro bought in the USA late in 2014. When I had to replace the HD in December 2015 the local Apple-certified company had to order teh HD from the USA. After installing it, they restored my software and data files and eMails in Mail.
Since the HD replacement I haven't been able to install any updates because after I give permission to update I get a notice that no updates are available under "this Apple ID" or something to this effect. After 8 months of failed updates my HD is slow again with my computer temporarily freezing and the colored please-wait wheel spinning every now and then. What should I do to allow the updates to succeed?
MacBook Pro with Retina display, OS X Mavericks (10.9.1), Ms Off 4 Mac prob, not a Mac prob.
