MBP 15' 2019 I intially noticed issues with my MBP connecting to external displays when it was not being charged. This was not big of a deal since normally I would have it being charged. But here comes the real problem. Since Big Sur 11.6, I was not able to have stable and strong connectivity to my wifi network as well as full CPU performace. I checked the latency and turns out that my MBP can't even keep up to a downloading speed of 300Kbps. Are you f**king kidding me? I'm a Korean and can't stand this type of lag while using the internet. I also spent 4 hours trying to upload an app to the app store but could not succeed due to this outrage. WHAT GOOD IS IT TO HAVE A MACBOOK PRO WHEN YOU HAVE AN OCTA-CORE CPU THAT WORKS LIKE SHIT AND WEAK WIFI CONNECTIVITY AS IF I WAS IN NORTH KOREA? Be ashamed Apple.
