 ### IBM DB2 development on macOS
 
-For IBM DB2 on macOS, there are only drivers for the `x86_64` architecture, not on `aarch64` 
-(see [this tracking issue](https://ibm-data-and-ai.ideas.ibm.com/ideas/DB2CON-I-92)). For this reason, you need to have 
-Rosetta 2 installed and create the conda environment in `x86_64` mode (see [here](https://pixi.sh/dev/reference/project_configuration/#platforms) for more info about this).
-
-```bash
-softwareupdate --install-rosetta

+Unfortunately, the `ibm_db` package is not available on conda-forge because the shipped library

 (see [ibmdb/db2drivers #3](https://github.com/ibmdb/db2drivers/issues/3)).
 Thus, we need to install GCC via homebrew in addition to the conda environment.
 
-On Apple Silicon (M1/M2/M3/...), you need to install homebrew+gcc using Rosetta (Rosetta uses /usr/local by default):
-```bash
-# 
-arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
-arch -x86_64 /usr/local/bin/brew install gcc

-On Intel based Macs:
 ```bash
 brew install gcc
 ```
