 # PurgeWrangler
-Allows you to use external GPUs with older macs, and also enables NVIDIA eGPUs on all macs.
+A lot has happened with **macOS 10.13.4** and eGPU support, but noticeably - the lack of:
+* **NVIDIA eGPU** support
+* **Thunderbolt 1/2** support
+
+**PurgeWrangler** aims to remedy this by patching *kernel extensions* on disk to bypass thunderbolt checks and enable NVIDIA eGPUs.

 ## Requirements
 This script requires the following specifications:
 * Mac with **Thunderbolt**
 * **macOS 10.13.4** or later
-* System Backup
 
-It is recommended that you have a backup of the system. Testing was done on a **Mid-2014 MacBook Pro w/ GeForce GT 750M**.
+A system backup is highly recommended. Although the patches and recovery techniques have been refined over time, having a fallback is always important.
 
 ## Usage
-Please follow these steps:
+To get yourself acquainted with eGPU support on macOS and some technical foreword, consider reading the [macOS Troubleshooting Guide](https://egpu.io/forums/mac-setup/guide-troubleshooting-egpus-on-macos/) at [egpu.io](https://egpu.io). To use **PurgeWrangler**, please follow these steps:

 For advanced users that may sometimes prefer bypassing the menu, the script provides convenient arguments in an attempt to be as user-friendly as possible.
 
 #### 1. Enable AMD eGPUs (`-ea|--enable-amd`)
-Enables default eGPU support on **Thunderbolt 1/2** macs.
+For **Thunderbolt 3** macs, allows the use of unofficial (non-Apple supported) AMD eGPUs such as the **Fiji** architecture GPUs. For older **Thunderbolt** models, bypasses the thunderbolt requirement and optionally allows use of unofficial AMD eGPUs. To use unofficial eGPUs, agree to enabling unofficial cards when prompted in the script.
 
 #### 2. Enable NVIDIA eGPUs (`-en|--enable-nv`)
-Enables NVIDIA eGPUs on **any** mac, regardless of **Thunderbolt** version.
+All **Thunderbolt** macs require extensive patching for NVIDIA eGPUs. This option downloads the necessary NVIDIA drivers, patches any macOS version requirements if needed, and finally applies the necessary system patches needed to allow eGPU acceleration.
 
 #### 3. Patch Status Check (`-s|--status`)
-Checks for the applied patches and provides system state information
+Check to see what patches are installed on the system.
 
 #### 4. Uninstall Patches (`-u|--uninstall`)
-In-place uninstaller for the patches.
+Uninstall any patches without restoring backed-up files, in-place.
 
 #### 5. System Recovery (`-r|--recover`)
 Recover original untouched macOS configuration prior to script modifications.
 
-#### 6. Disable Hibernation (`-dh|--disable-hibernation`)
-Disables hibernation mode and automatic power off as these settings may resolve wake-up failures with discrete graphics disabled.
-
-#### 7. Restore Power Settings (`-rp|--restore-power`)
-Restores the hibernation mode configurations to recommended settings.
+#### 6. Sanitize System (`-ss|--sanitize-system`)
+Resolve permission issues with target kernel extensions and rebuild kernel cache.
 
-#### 8. Reboot System (`-rb|--reboot`)
-Reboots the system with a countdown.
+#### 7. Reboot System (`-rb|--reboot`)
+Reboot the system.
