denkteich Posted May 25, 2020 Share Posted May 25, 2020 Hi All, after updating to 10.15.4 my USB3 Ports are not working anymore. Like on the Update to 10.14.6 With 10.14.6 enabling the USB Port limit patch #1-#4 solved the problem. USB Port limit patches are still in my config, but it's not working for 10.15.4. Any suggestions? TIA .d config.plist.zip Quote Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted May 25, 2020 Moderators Share Posted May 25, 2020 Best to generate USBPorts.kext or SSDT-UIAC.aml with Hackintool so you don't need to look for update patches on every update. Quote Link to comment Share on other sites More sharing options...
