I am using a 1TB My book for Mac which was formatted before I upgraded to Yosemite Ver 10.10.1. I can no longer use the drive and I can’t find a way to format it.
The instructions I have tells me to double left click on on the Internal Mac Drive (done) then choose Applications (done) then Utilities, which I can’t find, I have changed the view with the Columns button but still no Utilities button.
Can anyolne please help or tell me where I am going wrong or do I need to buy a new drive ?.
Thank you in advance
Regards
