Apple has simultaneously released patches for its desktop and mobile operating systems, bringing OS X Yosemite up to version 10.10.1 and iOS to version 8.1.1. Both bring a range of bug bixes and performance improvements, but most importantly promise to fix prevailing Wi-Fi issues across all Apple devices.
First up, iOS. Version 8.1.1 promises to make the operating system more stable than with previous iterations and nail down some smaller bugs. However, the biggest change is increased performance on older devices, which were struggling to cope with the upgrade to iOS 8. It's unclear exactly how much more responsive older devices will be after the patch, but iPhone 4S and iPad 2 owners shouldn't expect iPhone 6-level speeds.
iOS users with an iPhone 4S or newer, iPad 2 or newer, or a fifth-generation iPod touch can download the update now by heading to Settings, General, Software update.
OS X Yosemite, meanwhile, should finally have solved its Wi-Fi connectivity issues, which have been troubling some users since October. The update also improves Apple Mail reliability when sending messages using certain serice providers, makes it easier to connect to a Microsoft Exchange server and adjusts how notifications and widgets are displayed, eliminating a bug where they may not appear at all. Mac Mini owners struggling to wake their computer from sleep mode should also notice an improvement with the latest patch.
Apple has also added a few enterprise tweaks for business customers, improving remote login and remote desktop access using either Apple Remote Desktop or Back to My Mac - both useful fixes, but unlikely to affect regular desktop users.
OS X Yosemite 10.10.1 is available for free from the Mac App Store. Apple recommends that all OS X users update as soon as possible.
