"Thanks to every one for all the input. I think I'm just going to go for it. I will cut it to 5/4, sticker, stack it indoors, put cement blocks on top and blow a fan on it. Wait and see what happens, nothing is going to happen if I don't do something. If things don't work out it looks like I'll be smoking a whole buuuuunch of ribs!"
Do not blow a fan on your stacked and stickered apple if it's indoors in a climate-controlled shop. During this time of year, almost all climate-controlled shops are very, very dry unless you live in Florida. I speak from experience in this area - I mill and dry an awful lot of lumber myself, from the log. Blowing a fan on a small stack of lumber in an indoor shop environment with less than 50% R.H. is an almost sure-fire recipe for ruining your wood - it will quite badly surface-check, and probably honeycomb. Under those circumstances, it will only be useful for smoking bacon or ribs.
As most have noted, apple's stability largely depends on the straightness of the tree, or if it's compression wood taken from limbs. If the tunk of your tree was nice and straight, you should have some very workable wood.
In my case, I've dried several trees worth of apple, but since my objective was getting quarter-sawn wood for making handplanes, I split the logs into halves, removed the bark, and let it dry for a couple of years before sawing it. This is, by the way, one of the best ways to get stable, dry wood with the least effort and with the least checking.
