Legacy System Extension - Prolific Technology Inc

Hello,


I have a Mid-2014 MBP running macOS Catalina.


As we know, Legacy kernels are being unsupported in Big Sur and beyond. So I get this message:



But I have no clue what app have is from this company, and when I searched about it, it looks like it's some driver for i/o or something. I'm not able to find the .kext to get rid of it.


Any suggestions?


Thanks in advance,


Jack

I suggest you do nothing. As you wrote the .kext file will not even load in Big Sur. If and when you upgrade the message will cease to appear.


Are you using any USB to serial converters? The Prolific driver is used for a number of them from a variety of manufacturers, and perhaps other products.


If you still want to track down and remove the .kext please write back for suggestions, but my primary suggestion is to do nothing.
