Hello, recently, I have had forty to fifty Gbs missing (it is classified as "Other") and can't figure out where it is going. I have tried everything -- special software, deleting apps, etc -- but the results are always temporary. Anyway, I have decided to move my essentials to an USB, backup the entire Mac, and restore to factory settings and start all over. The problem I have encountered is that some very important apps (particularly, Photoshop elements and Microsoft word) may not be "backupable." So, is there a way I can just restore those apps without restoring the rest of the Mac? Thanks.
