Macbook Air - unable to run latest OS update

I am unable to run the update because 113.75 GB out of the 120.15 GB drive is being eaten up by "Other"! I have offloaded all the files onto a flash drive, re-indexed spotlight, emptied all the trash, deleted history, and emptied caches. All of that has increased the amount of Other 😟 There are only a handful of photos taking up 1.4 MB of space and apps taking up 4.71 GB.

We are headed to our Tampa Apple store Saturday to fix the problem, but I thought I would see if anyone else has experienced this issue and has a solution.

Thanks in advance for the help 🙂
