Install an old version with homebrew for macOS

old-version-homebrew.md

1. Find the formula for the version you want to install:

   • Visit https://github.com/Homebrew/homebrew-core/tree/master/Formula
   • Click the file with your formula (e.g. “composer.rb”)
   • Click “History” (top right)
   • Click the commit hash for the version you want to download
   • Click the three dots (top right of diff) and choose “view file”
   • Click “Raw” and copy the raw URL from the browser address bar.

   For example, composer 1.10.15 lives here: https://github.com/Homebrew/homebrew-core/blob/9e6e6a1ca8551901bff69d329c7fbb9007064134/Formula/composer.rb

   With the raw file at: https://raw.githubusercontent.com/Homebrew/homebrew-core/9e6e6a1ca8551901bff69d329c7fbb9007064134/Formula/composer.rb

2. Download the raw formula to disk:

   cd ~/Desktop
   curl -O https://raw.githubusercontent.com/Homebrew/homebrew-core/9e6e6a1ca8551901bff69d329c7fbb9007064134/Formula/composer.rb

3. Install that recipe from disk:

   brew install composer.rb (change composer.rb to the formula name)

4. Clean up:

   rm composer.rb (change composer.rb to the formula name)

5. Check the version for whatever you just installed:

   ❯ composer --version
   Composer version 1.10.15 2020-10-13 15:59:09

@nickcernis this worked perfectly i'm quite new to brew and MacOs, thanks for replying and helping!

@IgnacioAgustinCabral You're welcome! Glad it worked out.

This worked for me, thanks.

I made some notes about how to do this for a specific cask at https://gist.github.com/jpluimers/8da7d1f366936b0363e98b8baef1af98
