> Alternatively, you can set the scrollbars to be visible at all times by setting System Preferences -> General -> Show scroll bars to Always. One of the best things I think I've done for quality purposes is require all developers, QA team members, and project managers have scrollbars turned on at all times. It's sent the number of sites with hidden overflow in production down to near-zero for us. Someone, somewhere down the line will end up seeing that your page is 300px wider than the viewport before it hits production. And because that usually indicates other problems (often related to accessibility), it usually has a domino effect of discovering other issues that need to be fixed. It has definitely made a marked improvement to the quality of our work, and I recommend everyone require their teams using Macs to require scrollbars be set to "Always"
