Hello everyone,

My 2016 MacBook has a damaged internal drive, and it cannot be changed because it is soldered to the board. That's why I'm using a 500GB Samsung T7 to boot macOS Sonoma via OpenCore.

The problem is that everything goes quite slow: In the Blackmagic Disk Speed ​​Test it gives me approximately 380MB/s writing and 406MB/s reading. Isn't it supposed to go at least 600 mb/s? Since that SSD has a speed of 1050mb/s but through the port it goes like this I guess... but 380 is still very little... I don't know if it is a configuration problem, OpenCore, the external SSD or the limitation of the USB-C port on my MacBook.

I installed Sonoma on top of Big Sur, but the “Start Root Patching” button keeps showing up even though I already did it once. When starting up, pages take a while to load, and opening apps also takes a long time.

I was trying to do a clean install of Sonoma on the T7, but completely erasing the T7 also erased the OpenCore EFI boot and that's why the installation failed twice. So you can't do a clean installation on the T7? Or is there any way?

Any suggestions to improve performance or fix these problems would help me a lot.
