No Update Available
When I check software update, no updates are available. When I try to manually install the new OS trough the featured store, an error message pop up telling me to try again without actually telling me whats wrong. I've tried solutions in a number of sites telling me to create store account, login, etc etc but nothing works. I also dare to bet that the answer you're about to write is about a standard how-tos that I have tried and didn't work. I wouldnt want to try a clean install, because I have little to no experience with a mac (First mac in fact) and afraid of accidentally breaking it.
I have an old Macbook given to me by my boss, its Macbook Pro 10,1 (retina, Mid 2012) 2.7 GHz Intel i7 running OS X 10.9.5. A number of sites shows that this version of mac is compatible with the newer version of OS. But nevertheless I cant seem to get it upgraded.
Would you care to explain whats wrong, and kindly guide me to update ?
Thank you for your time, have a nice day.
