Apple has banned the use of two chemicals that endangered the health of Chinese iPhone assemblers: n-hexane, which is used to clean screens and could cause nerve damage and paralysis; and benzene, a known carcinogen that’s used to coat electronic components. However, these chemicals are still in use further up in the supply chain, and Apple is being pressured to eliminate them from the entire chain. follow link
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
