In news that should come as a surprise to absolutely no one, The Sims 4 Eco Lifestyle Expansion Pack which is due to be released on the 5 June is not available for Mac users running the Legacy Edition. If you are running the Legacy Edition save yourself the money and grief and don’t pre-order it or buy it when it is released. Nothing you do will make it work on your machine. There is no fix or workaround. If bundles are available and they include Eco Lifestyle, you will not be able to run it. The system requirements are very clear on the Origin site and state that a Metal supported Mac is required. For those still living under a rock, Legacy Edition is for Mac users whose Macs do not support Metal.
