So a little while ago I tried to backup my iPhone to my computer and got a message that I didn't have enough space on my computer. I went to check the storage and I only had 8GB left of free space. Odd since I hardly have anything other than music. Anyway, I opened up disk utility and saw, aside from my Sierra partition, I had an "Untitled" partition taking up 84GB. There's nothing there other than in the "other" section. I'm wondering if it's ok for me to delete this. I also just deleted the Sierra partition since I found I don't use it as often as I thought I would be. Any help would be much appreciated, thank you.
