Active Storage Variants Failing Locally

Setup

• ruby 3.0.4p208
• puma 5.6.1
• Rails 7.0.2
• macos 12.4 m1 #### Issue

I kept getting broken images when generating variants locally. I found the error below in my rails logs.

Error

[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called
[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called

Fix

I had to add this to my zshrc before I initialize rbenv

export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES
