iOS 10.9 - Maverick
 

I've tried downloading Chrome from the google site as a browser using the latest iOS version, but it won't allow me to open it because it didn't come from the app store, same with Opera. Chrome is not in the app store. Any ideas on how to possibily bypass the system and go back to normal downloading or has Apple decided they only want app store approved software on your iOS?

Open the settings app then security and at the bottom of the window are three options. Select the one that allows you I open third party applications from sources other than the mac AppStore.

If the options are greyed out click the padlock icon in the bottom left and enter your system password (the same one you used to install the apps)

Brilliant - thanks :ok:

(a) You would have encountered this behaviour on 10.8
(b) Its not "Apple decided" ... if you read the description of the default policy in System Preferences its "Mac App Store and identified developers".

Therefore the fact that Google can't be arsed to digitally sign their installers is not Apple's problem, its Google's arrogance.

The default policy of "App Store and identified developers" is for your own good, "Anywhere" is an obvious risk, and "App Store" although safer (because of the malware screening Apple do before listing on App Store) is obviously more restrictive. So the default policy gives you the best of both worlds.

" its Google's arrogance."

No its not
Its Google declining to pay the DanGeld to Apple to get them signed, and to put the software in the store

Much as most hardware suppliers declined to get drivers signed by Microsoft - until the arrival of IE8 and its rip-off enforcement policies
