OK, but with flaws

runs OK on yosemite/ osx 10.10.
however, there are some drawbacks. tried to submit this via the integrated “give feedback” function. however, that function seems to be inoperable -at least for two days now.
all in all: not satisfactory, as only one out of two books worked on the mac.

***
I just bought two e-books. I then installed the Kindle app for Mac. However, only one book could be downloaded - for the other (Object-C Programming, 6th ed.), I get the message "not compatible with device". How is this possible - not compatible with device?? This is a computer.

Oh, and now I cant send feedback: "please try again later". Lets see if it will work at some point.
