Hi all,

I have a iMac 9.1 (early 2009) and i'm looking to upgrade mac os to Mac OS 15 (Sequoia) but I have been hearing that there might be some issues with the usb 1.1 legacy drivers. (Specifically the legacy UHCI/OHCI drivers) I did some shallow research with my results landing on it might work as the iMac has 6 usb 2.0 ports instead of the usb 1.1 ports that would be affected.

Please tell me if i'm correct. Thanks!

You need usb keyboard and mouse when you install Sequioa, I am using Mac mini (Late 2009).
