I’ve seen a lot of speculation out there asking the above questions. I can now finally answer.
myHack v4 was nearly ready a few months ago but I have been so preoccupied there was simply no time to complete it and prepare it for release. Why? Because approximately 4 months ago my family and I decided to move back to the United States after 7 years in South Korea. This was a difficult decision to make, and was incredibly complex and time consuming to accomplish. I did however take the time to migrate this website to a new host to ensure there would be minimal disruption or downtime while myself and my hardware traveled across the globe.
I wanted to explain this months ago, or at least before I left but there were personal and professional reasons for not doing so. Not everyone was aware that I was intending to move and I wanted to keep it that way until I was gone. We arrived here about two weeks ago and are adjusting to our new timezone and environment. With the holidays we are also distracted by reuniting with family whom we have not seen in many many years, some whom have never even met our children. So it may still be a little while before I can get everything done on here that I have planned but it is most certainly going to be done. I have not abandoned the project but it does require a rather large investment of time to keep it going. Despite what some people have speculated I make no profit from this so it is low on my priority level, perhaps in the future that may change.
myHack 4 actually supports Yosemite fine, I had it working within 12 hours of DP1 being seeded by apple, there are other portions of myHack v4 that must be completed prior to me being able to release it to the rest of you however.
