This article is about driver installation only. If you need instruction on how to install CrossOver, please check this thread: viewtopic.php?f=4&t=7339

1. Install native MAC OS X drivers for the USB-UART chip in your adapter. Different chip require different drivers:

Silicon Labs: https://www.silabs.com/products/develop ... cp-drivers

You may use this tutorial to identify your USB to UART chip:

2. Map your USB device from MacOSX space to CrossOver space, here is the tutorial:

3. Latest version of OSX allow access serial devices only to root. In order to fix it, you need to run the following command in terminal:

>sudo chmod 777 /var/spool/uucp

4. Install FORScan, run it, go to FORScan settings ando do the following changes:

- Change connection type from Auto to COM

- Change COM port from Auto to COM1 (or whatever you set up in item #2 above)

- Change Maximum response time parameter from 300 to 1000 ms.

6. Try to connect

Hi, I'm running Catalina 10.15.6 and have followed all these steps and when i go to put the command in terminal it says "Operation not permitted" is there a workaround to this?

You need to be logged in as root. Type the following in terminal:
sudo -i sudo -s

Hey ya'll, I am new to FORScan and need your help. Just purchased a 2018 Ford F150 XLT and heard about ForScan through the dealership. Went and purchased the ELM327 USB driver from Amazon and got Crossover installed on my Macbook. I went through the sequence of steps to setup but when I hooked up to truck and ran it on the version FORScan for Windows v2.3.41, but the configuration shows:

Vehicle
Model: Ford Focus
Engine: Zetec
Capacity: 1.8L
Generation 1999 MY
Fuel: Gasoline
Transmission gear: Manual
VIN: FORSCAN

OBDII: On Board Diagnostic II

I don't know what to do from this point.

Appreciate the help.

The Connection dialog is set to Demo and the vehicle you are seeing is the Internal demo vehicle. Remove the Check mark in the Demo Mode box in the About(Gear Icon)General page!

Leave the "Debug Box checked!

Thank you. I initially had the demo box unchecked but was getting a "No adapter found. Check connection." I tried it again with your suggestion of re-unchecking demo box and I am still getting the No adapter found error message.

1. I uninstalled and reinstalled FORScan and Crossover (purchased license this time).
2. ELM327 switched to HS.
3. Device firmly plugged in.
4. USB connections look good.
5. Ran everything over again and am still getting the same message.
6. Went to settings in FORScan and tried each of the connection types and in the MS-CAN Support box have "HS/MS switch" entered.
7. Still getting the same message.

Any specific actions or thoughts?

Post the specific Adaptor you purchased from Amazon so we can see what parameters it is using! I am not very familar with Cross Over but when this happens in Wine with Windows crossing into Linux it is usually a COM port driver translation to USB(Linux Hot plug) that is the problem. At any rate Windows programs in Cross Over(have you tried accessing a data thumb drive in crossover) are not getting out to the Mac USB ports

Also If this MAC is new enough to have Thunderbolt ports make sure that you are not trying to run this through one of those as USB and Thunderbolt are not the same even though the cable looks the same!

The site keeps saying the file is too large.

It’s the blue/orange label that reads “ELM 327 Interface v1.5 Supports all OBDII Protocols” and has a HS/MS toggle switch.

I cannot get an OBD2EX to connect using Crossover and Mac OS High Sierra. I followed the steps above exactly and it still does not connect to an adapter. The adapter light is green and I've tried everything I can find to update drivers, etc. Please advise how I can use my MBP to connect to FORScan. Thanks.
