First, I want to thank the people who replied to my post yesterday about my MacBook air being so slow. However, I think I managed to make it slower. Maybe it's all in my mind. I am just so frustrated with my mac at the moment. Am I the only one who feels this way? I know that it's all new. But I hate it right now. For example, I can't get my arrow keys to work. When I press them, they make that sound, like nothing is there under them even though it says that File Vault has keyboard focus. Plus when I press VO key with space bar to click on stuff, nothing happens. I'm so discouraged with my Mac. I just can't seem to get used to it despite the fact that I read the Help section and come on this site a lot. I know that I've come along way since getting my mac couple months ago. However, I can't seem to get use to the screen layout. It seems so complicated. For example, when it says row expanded when I'm looking at a folder, does that mean the folders open? Why can't it just say folder is open? Or when i'm in email, and it says row expanded, what exactly is expanded? I suspect one reason it's so slow, because when I first got it, I was accidentally creating new folders and aliases all the time. Plus, when I updated from Yosemite, I had to install the update a couple times. So I'm sure there's files left over from that.
