[REQUIRED] Please describe the issue here:

iOS Resolver Failed to install CocoaPods for the current user:
Do a fresh install of macOS Monterey or buy new M1 Max Macbook Pro. Install Xcode 14.2 Install Homebrew with Command Line Tools (14.2). Install Cocoapods via Homebrew for M1 architecture. Do fresh install of Unity 2021.3.15f1. Check the pod --version to confirm Cocoapods 1.11.3 are installed and working. Check the ruby version to confirm you have default ruby version installed.
Open Unity project that contains External Dependency Manager
The External Dependency Manager starts to complain that Ruby 2.6.0 is not on the PATH. Workaround: adding to the PATH in the .zshrc: export PATH="/Users/your_mac_user/.gem/ruby/2.6.0/bin:$PATH"
The External Dependency Manager stops complaining about missing Ruby on the $PATH but still tries to install the Cocoapods.
Cocoapods failing to install see error output below

Expected behaviour: Don't try to install the Cocoapods if the Cocoapods are already installed in the system.

Please answer the following, if applicable:

What's the issue repro rate? (eg 100%, 1/5 etc)

What happened? How can we make the problem occur?

Hi @Kharion,

I noticed that you also filed a similar ticket (#589) with additional information. Let's have the conversation there so that all discussion would be contained in one thread. That said, I'll be closing this ticket for now.

[Kharion]

Hi, yes I've created second ticket because I see this as two separate problems. The first is about trying auto install already installed Cocoapods and second is basically about unable to run pod install (for whatever reason) when the option is enabled.
