This week on Dezeen, Apple's new Mac Pro and robotic IKEA furniture were among the innovations revealed by the two design giants at their annual conferences.

On Monday, Apple held its annual Worldwide Developers Conference in San Jose, California, where it unveiled its first redesign of the Mac Pro in six years.

Dubbed a "monster" by Apple's senior vice president Phil Schiller, the processor is encased in a simple, aluminium body. It is the brand's most powerful desktop computer to date.

Among the other launches at Apple's conference was a new dark-display mode and an operating system designed exclusively for the iPad.

Named iPadOS, the system features a customisable home screen and split-view capability, intended to make it easier for users to manage files, multitask and use Apple Pencil.

Over in Sweden, IKEA held its Democratic Design Days conference, which brought sustainable design and housing solutions into focus.

Among its new products were home accessories made from rice straw to help reduce India's smog problem, and small domestic solar panels developed with Olafur Eliasson to encourage people to harvest their own solar power.

A robotic, shape-shifting furniture system was also introduced.

Also at the conference, IKEA's research lab Space10 revealed its vision for a subscription housing model.

Developed with architecture EFFEKT, the Urban Village Project builds on Space10's research into the benefits of co-living in a bid to make cities more affordable and sustainable.

In architecture news, Apple Store designer Eight Inc proposed for a structural glass roof and spire for Notre-Dame, and Frank Lloyd Wright 1950's RW Lindholm House completed its move to Pennsylvania.

The industry also mourned the death of architect Stanley Tigerman – a founding member of postmodernist group Chicago Seven.

Photos revealed that Melike Altınışık Architects' Supertall Camlica TV and Radio Tower is close to completion in Istanbul, with only its facade left to install.

Meanwhile In New York, CetraRuddy released visuals of a bronze, art deco-style tower for the Rockefeller Group, which is currently under construction in NoMad.

Extinction Rebellion hit the headlines after withdrawing its visual identity from the Design Museum's Designs of the Year shortlist, and accusing the museum for artwashing "the unacceptable behaviours" of its sponsor, Beazley.

The museum has since defended the annual show, stating that it exists to highlight the role that design has in solving the problems of today, like climate change.

In more positive news, Dezeen spotlighted eight design brands, from Kvadrat to Emeco, that are doing their bit to help the planet.

Popular projects this week included a tiny house in Tokyo with funnel-like roofs, conceptual housing made from shipping containers, and the revival of Rudolph Schindler's Manola Court apartments.
