Today, I started pwsh on my M2 Mac. It started 7.4.0 and told me an update was available. I’m pretty new to MacOS. I tried brew upgrade powershell and it said something about it not being installed with brew, I think. I can’t remember how I installed it – it was when I first got the MacBook. I assumed I’d installed it before I found out about brew so I thought I should uninstall it and then reinstall it using brew. I tried following the uninstall instructions for a direct install. It didn’t seem to do anything. I tried various things – honestly, headless chicken doesn’t really describe it – I didn’t keep notes. I just wanted it done so I could get on with what I wanted to use PowerShell for.

tl;dr

I’ve tried:

brew update
brew upgrade powershell

Currently, pwsh still starts 7.4.0.

If I try to see what’s installed, I get:

9:56:17 ~ $ brew list powershell --cask
==> Pkg
powershell-7.4.4-osx-arm64.pkg (Pkg)

Before I found that command, I tried this:

9:56:28 ~ $ brew list powershell
