I own MIGplan and I'm telling you to save your money.  It is the only program to
run on a MAC that's available, but it costs $200 and ONLY gives you "run time", 
it doesn't break down the dive.  
Also, it is not well designed to do repetetive dives (they don't think you 
should do a repet deco dive).  It will do repet dives, but the "running clock" 
doesn't reset (which means if you first dive was 60 min total, then a 120 min 
surface interval, your "run clock" then starts at 180 min. for the 2nd dive).  
Makes sense, makes it easy for the computer to calculate, but is difficult to 
make into a table (unless you want to rewrite the whole thing.

Also, the Bottom time is:  beginning of ascent until you make it to your first 
stop.  This makes it hard to plan a dive.

Ex:  you want to dive 30 min at 100 ft, then deco at 20ft and 10ft.  For 
MIGplan, you would punch in 100ft for 33 minutes (30 min BT + 3 min ascent).  
Sound simple?  Not really.  If you don't know WHERE your first stop is, (is it 
30ft, 50ft, or 70ft?) it makes it difficult to guess.

Also, it does calculate your gas consumption, but you ONLY see that info IF you 
print out the table.  I'd like to know BEFORE I print it - It's a waste of paper
to find out that the dive isn't "doable" because of gas consumption.

There are some other quirks as well.  On some dives I've tried to "simulate", it
will skip a stop (you have a 70ft stop, then jump to 50ft).  I've never seen any
other software do this.  It may be right mathmatically, but not in real life it 
isn't.

I hope this answers your question.  Personally, I'd wait to see what Abysmal 
does.  They are supposedly coming out with a MAC version of ABYSS.

Good luck.
