I've had my old MacBook Pro since 2011 but this one has me stumped. One day last week I turned it on and all my data had been moved to iCloud. When I try to save a document it only goes to the cloud, not the computer. Now my data is not available unless I'm signed into the cloud and connected to the internet. How did this most likely happen and how do I change it so my data is once again available offline? I'm not entirely convinced the cloud is 100% secure so I have doubts about having all my data on it. I'm also signed into iCloud on my iPhone and iPad.
