Hi Everyone, I have a Retina Macbook Pro that we use in a professional photography business setting. The RMBP is having a problem of not having any space left. I have looked at all the files on the hard drive and have not found anything taking up that much space, including the trash bin. I have a feeling this has to do with deleting files via thunderbolt target disk mode from a connected iMac and the RMBP SSD not properly zeroing out the space due to the fact that the deletion request is coming from the iMac. Is there anyway for me to regain this space without having to do a entire OSX reinstall? thanks again.
