Word, Excel versions 2016 et al taking a long time to start? Some people report startup times of 60 seconds, even on Macs with solid-state storage!

Try the following, which rebuilds the dyld cache. Please don’t contact me saying this doesn’t do anything. It’s true that it shouldn’t help on a technical level but somehow it does appear to help those using Microsoft Office 2016 and who have long startup times for those apps. Go figure.

  1. Open a Terminal window, which you’ll find in the Utilities folder of the Applications list in Finder.
  2. Type the following two commands, one after the other, giving each time to finish. Note that you’ll be prompted for your login password. This is fine.
    sudo update_dyld_shared_cache -debug
    sudo update_dyld_shared_cache -force
  3. Reboot your Mac.
