I purchased Toast 18 Pro in December 2019. A strap line on the website reads: 'Roxio® Toast® - The preferred CD & DVD burner for Mac!' and in the body of the site: 'macOS 10.15 - Optimized for Catalina - Toast 18 has been redesigned as a 64-bit application and is fully compatible with macOS Catalina. Version 18 supports macOS Catalina 10.15, Mojave 10.14, High Sierra 10.13, Sierra 10.12, El Capitan 10.11.' The only problem, according to Corel, it doesn't support iMovie or Final Cut Pro, or other Apple files, without conversion! I was told by Corel to covert the iMovie file to an H.264 file, which I did. However, if you use the conversion tool in Toast, the results are stuttering with the audio out of sync - unusable! Anyone else have this issue? I am running macOS Catalina 10.15.2. and I'm very disappointed with what I'd heard was a good Mac program.
