I want to share with you how I solved a huge problem with my Macbook pro retina mid 2014 after the Mojave update. It worked smoothly before, after the update it started to become extremely slow in opening any non-Apple application (the worst ones were Parallels and Microsoft Office, the latter requiring 1-2 minutes to open). I have read elsewhere that it is a rather common issue that some user could not solve so far.
I restored the OS from scratch, and the problem appeared again as soon as I synchronized my Dropbox account. I started thinking that this might be a filesystem problem, due to the huge amount of data I have on Dropbox (190 Gb). I tried first removing the biggest files, with no results. I solved the issue removing two folders containing several small files (around 40 Gb split in 20,000+ files, as I work with computed tomography scans, composed by hundreds of small files 100-500 kb each).
Removing those files completely solved the issue, and now Mojave runs even faster than before the update.
Hope this helps someone.
