Slow reads on MacOs

[marcinjagielnicki]

Hello,
I would like to ask if anybody had issues with slow reads using pcileech on macos (ARM)?

I did a test and when card is connected to windows PC I'm getting ~180-190 MB/s but when connected to Macbook Pro M1 I'm getting only around 80 MB/s. I've tried different ports and the problem persists.

Apologies for the slow response. I always get a notification about issues created, but I must have accidentally forgotten to respond.

The reason for the macOS somewhat slower support are related to the FTDI USB driver and how PCILeech interfaces with it.

If maximum performance is of utmost importance a Windows PC would be the way to go unfortunately as things stand right now. macOS and Linux a bit slower due to driver issues, but I hope PCILeech is still quite usable even so.
