ANOTHER APFS TRIAL

I got to thinking about TechTool Pro's ProToGo and EDrive and decided to see if by any chance it could create a bootable image of High Sierra. The answer is no it cannot. As I have said the developers of Diskwarrior, Drive Genius, and TechTool Pro have a long row to hoe getting compatible with High Sierra and APFS. On top of that much of their value and justification in the past has been rendered questionable if not moot by APFS.

If we knew what it was we were doing, it wouldn't be called research, would it?
