Mac iOS 9 users have recently reported app hangs and even total crashes when tapping links involving multiple iOS and devices. Apple now admits that their software engineers are developing a fix for the issue and it will be released in a software update, possibly an iOS 9.3.1.

"We are aware of this issue, and we will release a fix in a software update soon."

There is no temporary solution to the problem at this time. But those who have investigated the issue have a suspicion on why the bug has appeared. They believe that it is dependent on the apps that the user has installed and how such apps take care of universal links.

In a related development, a report revealed that Apple has just released a fix for iPad and iPhone devices affected by the iOS 9.3 activation bug. This new version of iOS 9.3 is only for older iPads and iPhones that experienced locking due to a defective activation process in the initial setup.

This latest version called iOS 9.3 takes care of the "activation bub" which leaves certain older devices unable to continue the process of activation beyond the step of confirming the ID and password associated to a device, if the password was forgotten by the user.

The Cupertino, CA-based company suspended iOS 9.3 last week for iPhone 5s and early models due to activation problems, but later released on Monday a new version for older models with a build number 13E237 to differentiate them.

Concerning the bug that causes Mac devices to hang and crash, some investigators thought that Bookings.com causes the bug to appear. It was found that with Twitter, this website's association file was grossly oversized by many megabytes.

This condition will practically overload the daemon used to parse the files, thus inducing the crash. The app from Bookings.com has corrected its payload file to a very reasonable size of 4 kilobytes. Users of this website need to delete and reinstall the app so that the system caches will be refreshed for the URL association file.
