Apple introduced mouse support with iOS and iPadOS 13, as an accessibility feature enabled through AssistiveTouch or Switch Control. However although the feature hasn’t officially worked with their own Magic Mouse 2 or Magic Trackpad since launching, most have got it working.
Apple has released iOS 13.4 with support for mouse and trackpad on iPad. The feature works with any third-party bluetooth accessory, Magic Trackpad 2 and Magic Mouse 2. You can connect a mouse or trackpad by going to Settings > Bluetooth and waiting for your device to appear.
However, if you’ve updated to iOS 13.3 or iPadOS 13.3 (or later), there’s a very strong chance that support for these bluetooth accessories no longer works. Users on online forums are complaining that they cannot find any way to connect their Magic Mouse 2 to their recently updated iPad – and Apple TLD can confirm this.
It’s likely that, with the 13.3 release, Apple has made a change that prevents these devices from connecting after becoming aware of simple workarounds. Up until this point the company made it awkward to use and pair their own Bluetooth accessories with iPads and iPhones, but it’s seemingly impossible now due to a back-end change.
Of course, this could be a bug, but with the 13.3.1 update there are no signs of unofficial support returning. Hopefully, with iOS 14 and full mouse support, Apple changes its mind and lets Magic Mouse 2 and TrackPad 2 users control their mobile device.
