Resetting your network settings in macOS requires deleting certain system configuration files. For tips on backing up your Mac, see Back Up a Mac. For example, you'll want to close your web browser, messaging, and social media apps. To do this, click the Wi-Fi icon in the menu bar and select Turn Wi-Fi Off. It's the two-toned smiling Mac logo in the Dock, which is usually at the bottom of the screen. This opens the Go To Folder window.  This opens a list of System Configuration files. Here's how:  Press and hold the ⌘ Command key. Click all of the following files (while continuing to hold ⌘ Command):  com.apple.airport.preferences.plist com.apple.network.eapolclient.configuration.plist com.apple.wifi.message-tracer.plist NetworkInterfaces.plist preferences.plist   All selected files should now be highlighted in blue. You can drag them to your desktop or any other folder on your computer. It's just important that they are no longer in the SystemConfiguration folder. To do this, click the {"smallUrl":"https:\/\/www.wikihow.com\/images\/f\/ff\/Macapple1.png","bigUrl":"\/images\/thumb\/f\/ff\/Macapple1.png\/29px-Macapple1.png","smallWidth":460,"smallHeight":476,"bigWidth":"29","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Mac icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a><br>\n<\/p><\/div>"} menu and click Restart. Your computer will shut down and restart. Since your network settings will have been cleared, you'll have to re-enable Wi-Fi and connect to your network again as though you're doing so for the first time.

Chugging a bubbly, foamy beer can cause stomach pain, gas, and nausea, so wait for the bubbles to go away before you start. Waiting also gives the beer a chance to warm up a bit, which can help prevent brain freeze after you chug! The shape of the glass can affect how well you’re able to chug your beer. A beer mug is much easier to chug than a snifter. The carbonation in your beer is caused by carbon dioxide (CO2). All that extra gas pumped into your stomach can cause discomfort and possibly nausea. An easy way to release some of that CO2 into the air rather than your stomach is to knock the bottom of the glass on a table or solid structure before you chug it. Don’t slam your glass on the table, just knock it to shake some of the bubbles loose. Before you actually start to chug your beer, take a big breath to prepare yourself for what lies ahead. Moving your head into position ahead of time will streamline the process and make it easy to dump the contents of your glass right into your belly. Make sure you’ve got a good grip on the glass as well. After you’ve taken a breath and steeled your resolve, move the glass to your mouth and place your lips around the edge of the glass. In one swift motion, turn the glass up to pour the contents into your mouth. Don’t sip or gulp the beer or the liquid may spill out of the edges of your mouth. Be careful not to knock the glass against your teeth and risk chipping a tooth. As the contents of your glass enter your mouth, do not swallow. Instead, allow your throat to relax and the beer to flow directly into your stomach. Let gravity do the work for you. Be sure to hold your breath and don’t stop the flow of beer to take a breath as this will slow you down and possibly cause you to spill precious drops of beer. Imagine you are pouring a glass of water down an open drain. You’ve made it this far, don’t stop now! Keep your throat relaxed as the beer flows out of the glass. Tilt the glass further and further up to finish draining it. When the beer is gone, resume breathing, and bask in the glory of your achievement. There’s still plenty of CO2 in the beer, so if you need to expel any of the gasses in your stomach, a solid belch should do the trick.
