Remove Warning messages from LiveView on startup in MacOS

On Mac You can remove spurious warning messages (MessageTracer: load_domain_whitelist_search_tree:73: Search tree file's format version number (0) is not supported and MessageTracer: Falling back to default whitelist) from LiveView on startup by running this command in the command line:

xattr -w format_version 1 "/Library/Application Support/CrashReporter/SubmitDiagInfo.domains"

This command only needs to be run once.

Notes about what a "tap" is

In a camera link interface, a tap is a serial data line that sends data at about 10MHz for a typical connection. Therefore, the number of taps in a camera configuration files typically refers to the number of parallel camera link data lines are present in the data stream. Based on the frequency of the serial data coming across a single tap, this corresponds to about 160 crosstrack pixels of data. For example, for a number of taps = 2, that would mean the resolution is 320 in the crosstrack. If a camera stream had an actual resolution of 640x480, but only listed 2 taps in the camera configuration file, it may either mean that the .cfg file is misconfigured for the camera stream, or that the camera link interface is running at double the clock speed.
