 # PurgeNVDA
 **purge-nvda.sh** is required for certain macs to configure the system further for working external GPU support, alongside [purge-wrangler.sh](https://github.com/mayankk2308/purge-wrangler). It may also serve useful for other use cases such as bad discrete GPU chipsets, etc., but is not tested or guaranteed.
