I bought two of their programs several years ago, Mighty Mouse and Menu Master. They weren't expensive - I believe each was either $10 or $15. I also used APE to enable a slick feature called "Clear Dock" which created an opaque or translucent background behind the dock so it didn't matter what your desktop picture looked like. The feature was free. OS X 10.5 came along and all of this went away. Then, after blaming Apple for everything except hunger in Africa, the got things working, but not Clear Dock.
I recently bought an iMac 21.5" and once again everything went away, despite their claims that everything worked. I had also bought Font Card but frankly, I don't care if it works or not.
The problem is that they totally ignore any and all emails sent to them with questions about their products. My emails were not hostile and contained no profanity. The last one I sent was about two months ago when I had my old system and something still didn't work.
On their web site they claim that everything works under 10.6. If so, then why does the system give a message that it can't load anything because it hasn't been tested under Snow Leopard. I've been a Mac user for 19 years and I've never seen such lousy customer support. (I'm also sure they won't give a damn about this review, either). You don't get what you pay for from Unsanity, paying very little and getting nothing in return.
I just checked the "stability" box below. My comment on that, is that under 10.5 my system would freeze, and I mean totally freeze - couldn't even relaunch the finder. A couple times I even got the infamous "black screen of death"> Did they respond? Of course not.
