After a week apart, I've been reunited with my Mac... with a new hard drive... I couldn't get my old hard drive back because the service center people said they sent it back to Apple. Apparently it was broken in two.
I'm not going to freak out.
I've downloaded the essentials again... but I'm missing my copy of Office Mac terribly! Open Office will have to do for now.
I also need to invest in an external hard drive asap.
A brand new hard drive begs for a fresh start.
Here I go.
