Downgrade E+ on mac

asked Apr 25

updated Apr 25

Hi all - I am trying to downgrade from 24.2 to 23.2

Just tried to uninstall with the maintenancetool but the app refuses to run (message is "The 'maintenancetool' application can't be opened") - Can I just drag the application folder to the trash instead?

  1. Yes, you can trash it. The maintenance tool would just remove the symlinks that are placed at /usr/local/bin (see at end)
  2. If you want to use an older E+ version without removing the newest one, just call E+ using the full path or change your PATH variable to make the E+ folder first in line

example:

/Applications/EnergyPlus-23-2-0/energyplus -w /path/to/epw -d out in.idf
# Or
export PATH=/Applications/EnergyPlus-23-2-0:$PATH
energyplus -w /path/to/epw -d out in.idf

$ ls -la /usr/local/bin/ | rg EnergyPlus

Install homebrew https://brew.sh/ if you don't have it already, then brew install libomp

For any future folks - i had to install homebrew and also a library called libomp, then e+ 23.2 finally worked
