Mastering the Mac OS X Terminal with Scala: A Step-by-Step Guide

As a Mac user, you're likely familiar with the versatility of the Terminal application on your computer. However, if you're a developer or IT professional working with VMware Fusion and vSphere, you may have encountered issues setting custom display resolutions for your virtual machines. In this article, we'll explore how to overcome this limitation using a special utility called vmware-resolutionSet.

The Challenge: Overcoming the Limitation of Custom Display Resolutions

If you're running Mac OS X 10.9 (Mavericks) or newer in a Virtual Machine on VMware Fusion or vSphere, you may have noticed that you can no longer set a custom display resolution beyond the default 1024x768, regardless of the amount of video memory allocated to your virtual machine. This limitation is due to changes made by Apple in how it remembers previously used modes, which causes the system to automatically fall back to the default resolution instead of retaining the custom mode using the Display Preferences.

A Workaround: vmware-resolutionSet

Fortunately, VMware Engineering has developed a workaround for this issue in the form of a standalone command-line utility called vmware-resolutionSet. This utility runs within the Mac OS X Guest and allows you to configure a custom display resolution. However, as it's not an officially released tool, it's only available through filing an SR with VMware Support and referencing PR 1385761.

Using vmware-resolutionSet

To use vmware-resolutionSet, ensure that you have VMware Tools installed and running on your virtual machine. Then, follow these steps:

1. Open the Terminal application on your Mac.

2. Navigate to the location where the vmware-resolutionSet utility is stored: /Library/Application Support/VMware Tools.

3. Run the command `vmware-resolutionSet` followed by the desired display resolution (e.g., `vmware-resolutionSet 1920x1080`).

4. Press Enter to apply the changes.

Troubleshooting Tips

If you encounter any issues while using vmware-resolutionSet, here are a few troubleshooting tips to keep in mind:

* Make sure that VMware Tools is installed and running on your virtual machine.

* Verify that you're running the correct version of vmware-resolutionSet (the latest release is 10.0.5).

* If you encounter any errors while running the utility, check the system logs for more information.

Mastering the Mac OS X Terminal with Scala requires a deep understanding of the underlying technology and tools used to manage virtual machines. By leveraging the vmware-resolutionSet utility, you can overcome the limitation of custom display resolutions on VMware Fusion and vSphere. Remember to always follow best practices when working with command-line utilities and ensure that you have the latest version of VMware Tools installed on your virtual machine.
