Don't know exactly which [CP210x VCP Mac OSX Driver] it is. where can i find that on the Mac?
Two ways to find out which one you are using:
1. Option-Click the black Apple icon in the extreme, left-hand edge of the upper menu. Choose "System Information..." (image #1 below)
2. Click the black Apple icon in the extreme, left-hand edge of the upper menu. In the Overview tab, click the System Report...". (image #2 below)
In either case, scroll the left-hand list of items, looking for "Extensions" (image #3 below)
The large text block has all the info on the extension. The "Yes" in the "Loaded" column shows if it is being used. Hope that helps.
I would suggest getting your new set up running first. If it runs, great! If not, download and install the new
CP210x VCP Mac OSX driver. Either way, please post your progress or any other questions.

By the way, my English is only a
bit better than yours!
