Tried the download of OS8 and I don't like it. It has slowed my iPad Air to a crawl. I have plenty of storage capacity. Booting up has slowed. The new keypad sucks. Safari layout has changed. Very discouraged...Can I return to OS7? If so, how?
Any download of OS X or iOS other than from Apple or an official Apple source is illegal and is considered a pirated download. If you think otherwise, I suggest giving Apple customer service a call and ask.
