I can’t use the Capitan with illegal copies of anyone’s stuff.
Apple didn’t sell me this software. They still own it, in fact. I’m just borrowing it.
If I install more Apple software, those are on loan as well.
I can use the Capitan in two virtual Machines, plus once on my computer.
But these VM’s cannot be used for business. The only exception is for software developers (I guess they wouldn’t follow this rule anyways.)
I’ve got to read the separate rules that came with the fonts, and obey them. (I can only borrow those too.)
Those cool voices for the clock? — no remixing!
Slideshows made with Photo; same deal, don’t even think about using them for some commercial purpose.
I can’t sell access to my Mac via any kind of screen sharing.
I gotta run it on Apple hardware (no Hackintoshes).
I can’t help anyone else do that.
I can make one copy as a backup.
I can’t try to figure out the source code to any of this.
I gotta follow all my local laws while I’m using it. (!) (Really? Whereever I live?)
I can leave the software on the Mac if I sell it or give it away.
I better not use anyone else’s hacked version.
Apple isn’t responsible for my hurt feelings for anything I see on the web.
If I break any of these rules, this deal is over and I must immediately delete everything.
The Capitan is AS-IS, of course.
I can’t send it to Sudan.
I cannot, don’t even think about it, just plain can’t, make money from MPEG/H.264/AVC videos I create. For that, I need to buy another something from somebody.
