Apple has had a busy 2013. We've seen the release of the iPad Air, Retina iPad mini, iPhone 5s and iPhone 5c as well as the launch of a new Mac Pro and an update to the iMac, Retina MacBook Pro and MacBook Air. We've also seen new software from the company, including iOS 7 and OS X Mavericks. Here, we recap Apple's January 2013, which included the Do Not Disturb dilemma, Steve Jobs' yacht's first outing, 40 billion iOS app downloads and iMac shipping delays.

Apple didn't get off to the best start to the year, as the iPhone's Do Not Disturb feature caused many users to wake up late.

iOS's Do Not Disturb mode lets you configure specific hours during which your iOS device won't bother you with phone calls, text messages or notifications. But on New Years Day 2013, the feature didn't turn off when it was supposed to, causing lots of oversleeping around the world.

To make matters worse, Apple aired a new television ad on 2 January to show off the Do Not Disturb feature. The ad showed tennis stars Venus & Serena Williams playing a game of ping pong with the narrator, who is describing it as a "really cool dream" and continues to say "I don't wanna be disturbed." Oops.

On 3rd January, Apple posted a fix for the problem, which continued to persist. That fix was to wait until the iOS 6.1 update, which eventually arrived at the end of January.

Apple expanded the option to upgrade to its Fusion Drive to all of its iMacs in January, including the 21.5in iMac.

Also in early January, the first sign of iOS 7 emerged. Apple's new mobile operating system (which was eventually released in October after being previewed at WWDC in July) was spotted in app usage logs by developers.

Steve Job's yacht, Venus, was released in January following a payment dispute between Jobs' family and Philippe Starck, the yacht's designer, and was spotted near the Canary Islands later in the month as it made its way to the US.

On 7 January, Apple's iOS App Store passed the 40 billion downloads milestone, with almost half of those downloads taking place in 2012 alone.

The whole of January was plagued by iMac shipping delays, that were said to be caused by mass production issues that prevented Apple from being able to make the displays of its 27in iMacs fast enough. Shipping estimates didn't improve until March, and Apple CEO Tim Cook has since admitted that the company shouldn't have announced the new iMac until 2013.

On the last day of January 2013, Macworld UK published an Apple exclusive that revealed that the company would stop selling the Mac Pro in Europe from 1 March, because it no longer complied with safety regulations.
