+9Hi all. During a monthly chat with my security contact regarding software version compliance, the difference between 2 High-C builds was called out, and I can't find out the difference between the two. Would any of you all have any info regarding why 10.13.6 has two builds, but the release date is the same? Screenshot below.
Thanks.

@steve.summers The 17G2208 build is a 2018 model MacBook Pro (they came with a special build of 10.13.6). You may also find a 17G2307 build for the 2018 MBPs.
