Blu-ray Creator - Best Blu-ray Burning Software Free Download

Caveat: this appears to be a 

Adobe Encore CS6
Must be purchased with a creative cloud membership now (as part of Adobe Premiere) because the disc version of the software has not been available for over two years.
Many professional video editors use Encore as their go-to for DVD and Blu-Ray authoring, but it does have a learning curve if you're not familiar with Adobe applications.

Thankfully you can overcome this learning curve by watching a few Youtube videos to learn the interface:

Sony DVD Architect Pro 6.0 (at B&H Photo Video)
Can author both DVDs and Blu-Rays
$150 
Doesn't appear to require any other software, as long as you can feed it your final edit exported from your video editor of choice.  This seems like it would be a comparable alternative to Adobe Encore.
"supports popular video and audio formats such as AVI, MPEG-1, MPEG-2, and AVCHD so you can make a DVD or Blu-ray disc that will play on almost any DVD/BD player or DVD/BD-capable computer."

Tips for Blu-Ray authoring:

Use high-quality, reliable media. Getting the cheapest discs possible may actually cost you in the long run because their lifespan will be shorter and you'll have more discs that fail to burn, leaving you with a coaster.

Deciding on encoding format.  In your video editor, you can export either MPEG-2 for Blu-Ray or H.264 for Blu-Ray.  MPEG-2 can be used for videos that are one hour or less.  If your videos are longer, use the H.264 encoding options.

Use Windows NTFS External Hard Drives on a Mac

Exchanging large files between Macs and PCs has been a royal pain in the rear for several years now.  If you're a mac user, you're bound to encounter an external hard drive in the Windows NTFS format that needs to have files added from a Mac.  This is not possible without special software to add a NTFS driver on your Mac so that you can write (add files) to the drive.

This week I needed to copy 300GB+ of files from a Mac-formatted HFS+ external hard drive to a client's NTFS formatted backup drive, and here's are the best options I found after a little research.
