Hey girls and guys,
i have a 2020 MBP (4TB) and since 10.15.6 I have an enormes amount of problems with this machine - especially with Thunderbolt Docks (mentioned in specific thread). But since 10.15.7 my MBP is even having problems connecting with a 4K USB-C display (HP Z32). Since I can't use my Thunderbolt accessory's anymore (Bug since 10.15.6) I drive my 4K display over the USB-C connection, which powers the Macbook, delivers Data (USB 2.0 speed) and of course the picture. Before 10.15.7 I was able to do drive the display in 4K @ 60 Hz no matter the scaling. Now the MBP sometimes does not even recognize the display (especially in clamshell mode) and when it does - it is only able to drive it @ 30 Hz which is almost unusable for me. I habe now figured out, that I can drive it @ 60Hz if I set the scaling to "native". But 4K in native resolution is quite tiny .... So I wonder why suddenly the MBP is not able to do this. I tried another cable - same problem. Tried both cables with an iPad Pro (2018) and there it works, so seems like the MBP is the faulty one.
I am already really angry, that this machine has been so unreliable before, but now its almost impossible to work with this thing. When I have time I will (again) completely wipe it and try my luck but it seems really strange that each update has made this machine worse. Maybe someone has an explanation or the same problems or even a solution.
