You didn't give a lot of details about what exactly you did to perform this update of the operating system. If you had to erase the entire hard disk, that's important for you to state.
In any event, you need to locate your catalog file, andd you need to locate your photos. If you have these, let us know, we can tell you what to do next. If you think they have been deleted in this process, then you'd have to restore the catalog file and photos from backups.
It did erase my hard drive but I have everything backed up on a external hard drive. So what happened when I went to open LR it had erased everything. I called apple and they said before adobe is a third party that importing them could be different since the info wasn't just there like the other apple programs. I just found a backup from today and was able to restore pictures but I still don't have any presets.

Do you or do you not have backups of your presets?
First, why did it wipe the disk???
Second, did you have a Lightroom Back up - which won't have presets, or a Computer Back Up which will...
Dj_Paige I think I have backups of my presets. I found them but do I have to manually add each one back in?
Geoff the kiwi, I am sorry I was wrong it did not wipe the disk. It back up some of it. I was able to find a catalog last night on the backup disk and bring it back to where I was at before all this happened but I just don't have any presets. When I tried to use time machine to take things back to where it was before it didn't work. Do you know if I have to manually add in all the presets again?
This document describes what folder the presets should be copied into.
So, close Lightroom, copy the presets, then open Lightroon.
