Original Question:

So I have Big Sur installed with OpenCore, but I had the same issue with Catalina. With the basic VoodooPS2 kext the touchpad does not work at all currently I'm using this build of it, but I've tried many other as well. I always had the same problem it only works at 1/10 of the time, it simply boots up and the system prefrences says no trackpad detected, but rarely when it boots up everything works fine. Kextstat says it is loaded no matter which case is it. ​ ​ Laptop model Dell Latitude E6530 Trackpad Alps PS2 OC 0.7.1 MacOS BigSur 11.4 [Link removed to comply with Google AdSense and copyright guidelines] ​ https://preview.redd.it/ctk0w86095d71.png?width=1210&format=png&auto=webp&s=9b769937796e6920034de5647bcd41d73a3a3bbf submitted by /u/Mecso2 [link] [comments]
