Hi all, I didn't have enough room on my iPhone to update to iOS8 over the air so I instead did it through iTunes. Due to the installation and extracting software and backing up my iPhone, the storage on my macbook pro dwindled down and in the end took about 8GB of hd space. I know that when installing software it uses some hd space but I thought that most would return after it installs and reboots. So, what do I do? Can I get that space back? Is there a file that I don't need anymore on my computer that I can get rid of? All help would be appreciated! I am down to 3GB of hard drive left. Thank you!
