I did this fix and it worked but once updated to macOS Catalina, my MBP (Late 2013) freezes/shuts down after a 3-5 minutes when not connected to an external display.
Does anyone have a suggestion to adjust this fix to work with Catalina?

''Here is a way to workaround that broken ThunderBolt chip: Simply turn off the ThunderBolt chip/ports (you can likely live with that):. Steps:''
# ''Disable SIP and reboot''
# ''Open terminal and enter:''
''sudo mv /System/Library/Extensions/AppleThunderboltNHI.kext /System/Library/Extensions/AppleThunderboltNHI.kext.BAK''
''Voila. Afterwards you may want to turn SIP on again (‘csrutil enable’)''
