On a Mac, you may need to MS-DOS Format the drive in terminal using command line using diskutil rather than the GUI Disk Utility App.
Tested on USB2 32GB thumb drive.
Open Terminal.app in /Applications/Utilities
Find the thumb drive in the diskutil list
diskutil list
Returned output should show a list of two or three or more "disk volumes"
dev/disk0 and dev/disk1 are likely your mounted volume drive and recovery drive
You need one that is "External, Physical"
/dev/disk3 (external, physical):
and should have a Column for the "Name" which might be "UNFORMATTED" or "BLANK" or "UNTITLED" whatever the inserted thumb drive is called in Finder
Then run the command to partition the disk (make sure you know which disk, cause you can screw up another drive pretty easily here.)
diskutil partitionDisk /dev/disk3 MBR ExFAT BLANK 100%
***This says partition Disk 3 with MBR (Master Boot Record for DOS) with an ExFAT Volume called BLANK at 100% of the space available***
Next. Unzip command directly to the new Drive volume.
replace the "File-From-Ford" with whatever you downloaded and "BLANK" with whatever you named your drive above
unzip ~/Downloads/FILE-From-Ford.zip -d /Volumes/BLANK/
The returned output may take a while for each file to transfer NOTE THE Warning line, because it was zipped by a Windows developer.
Archive: /Users/yourname/Downloads/FILE-From-Ford.zip
extracting: /Volumes/BLANK/DONTINDX.MSA
warning: /Users/yourname/Downloads/FILE-From-Ford.zip appears to use backslashes as path separators
inflating: /Volumes/BLANK/SyncMyRide/FILE-From-Ford-THA.tar.gz
inflating: /Volumes/BLANK/SyncMyRide/FILE-From-Ford-TBB.tar.gz
inflating: /Volumes/BLANK/SyncMyRide/FILE-From-Ford-SC.tar.gz
inflating: /Volumes/BLANK/SyncMyRide/FILE-From-Ford-BD.tar.gz
inflating: /Volumes/BLANK/SyncMyRide/FILE-From-Ford-AL.tar.gz
inflating: /Volumes/BLANK/SyncMyRide/FILE-From-Ford-BA.tar.gz
inflating: /Volumes/BLANK/SyncMyRide/FILE-From-Ford-AA.tar.gz
inflating: /Volumes/BLANK/autoinstall.lst
you should have two files and a folder called SyncMyRide
inside the SyncMyRide Directory it has all the installs.
NOTE: If you unzip by double clicking the zip, the Archive Utility doesn't make the SyncMyRide Folder. Make it and drag in the files ending with .gz
when you see a prompt ending in $ again, it is done and you can eject the drive and go upgrade
It took mine going from ver 1 to ver 3 a little over 30 minute and it rebooted once in the process, after the reboot it continued to install more files.
