Description of issue

Hi,

I'm on an intel iMac, and when I want to get information about a developer tool called Lazarus using brew info lazarus I got the following response:

==> lazarus: 3.6
https://www.lazarus-ide.org/
Deprecated because it no longer meets the criteria for acceptable casks! It will be disabled on 2026-01-26.
Installed
/usr/local/Caskroom/lazarus/3.6 (265.6MB)
From: https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/l/lazarus.rb
==> Name
Lazarus
==> Description
IDE for rapid application development
==> Dependencies
fpc-laz (cask), fpc-src-laz (cask)
==> Artifacts
Lazarus-3.6-macosx-x86_64.pkg (Pkg)
==> Caveats
lazarus is built for Intel macOS and so requires Rosetta 2 to be installed.
You can install Rosetta 2 with:
  softwareupdate --install-rosetta --agree-to-license
Note that it is very difficult to remove Rosetta 2 once it is installed.

==> Analytics
install: 20 (30 days), 81 (90 days), 620 (365 days)

The interesting part is when brew informs me that lazarus is built for Intel macOS and so requires Rosetta 2 to be installed.,
and even suggests the command to install it, even though I'm using an Intel based macOS...

It's not a showstopper or anything like that, but it's incorrect, and may cause difficulties for those who follow the suggestions.

Cheers,
Imre

To confirm, what's the output of echo Homebrew::SimulateSystem.current_arch | brew irb --pry?

[ImreLovasz]

Hi,

Here's the output of the aforementioned command:

Warning: irb is a developer command, so Homebrew's
developer mode has been automatically turned on.
To turn developer mode off, run:
  brew developer off
