x 4 in. 8 in. boards. These boards will make up the post to the punching bag. To create the shape you need, place two boards on top of each other and then place the remaining board along their 2-inch sides. Glue the boards together using wood glue. Make sure you run the glue along the lengths of the boards. Once they are glued, screw them together. You want them to stick out so that they can help the board stay in the concrete mix. Nail the plywood into the bottom of the boards. The plywood needs to be big enough to support the three boards while standing... You want the glue to dry completely before moving on to the next steps. Make sure they are evenly stacked. The tires will form your base. Use four bags of concrete so that you have enough to fill the inside of the tires. Place the bag of concrete inside of the wheelbarrow towards one end. Cut the bag open using a hoe. Once it's open, pour out the mix and remove the bag. A wheelbarrow allows you to mix the concrete easily. You can use a shovel or spade instead of the hoe. With the concrete on one side of the wheelbarrow, pour the required amount of water into the other side. To find the required amount of water, read the bag of the concrete mix. Adding more than the required amount can render the mix ineffective. Make sure to keep about 4 cups of water nearby in case you need to add more to the mix. Using a hoe, gradually mix small amounts of the concrete into the water. Keep mixing until the mix is completely wet. As you mix the concrete, make a pile of wet mix on one side of the wheelbarrow. Place the post inside of the tires and then fill the tires completely with concrete, making sure there are no empty spaces left inside. While the concrete is still wet, make sure that the post is leveled and centered in the tires. Smooth the top of the concrete. Make sure you wear gloves and safety goggles when pouring and maneuvering the concrete. The concrete mix can cause serious burns. If you move on to the next steps and the concrete is still dry, then the post will be uneven. Once the mix is dry, the base will become very heavy. To maneuver the stand, angle the post down and roll it using the tires. The futon mattress will be used for the padding of the punching bag. Lay the post down. Attach one end of the cut mattress to the post by using duct tape. Wrap the remaining part of the mattress until it is completely around the post. Tape the loose end of the mattress down with duct tape. Make sure the mattress is wrapped tight so that the punching bag has structure. Check with your local classifieds or online postings to find a futon mattress if you do not want to purchase a new one. Now that the mattress is secured to the post, wrap the exposed area with duct tape. Make sure you overlap as you tape so that you have very tight layers. You will cover every bit of exposed mattress that runs the length of the post. This will completely secure the mattress and make it suitable for punching. The pad will help keep the bag quiet when you hit it.

Summary: Combine three 2 in. Drive large nails into each board. Attach a square piece of plywood to the boards. Let the post set overnight. Stack two tires on top of each other. Dump the concrete mix into a wheelbarrow. Add water to the concrete. Slowly mix the concrete. Add the concrete mix to the tires. Let the stand set for two days so that the concrete mix can dry. Cut an old futon mattress in half. Cover the mattress with duct tape. Place a foam pad under the tires.

NVRAMshort for "Non-Volatile Random-Access Memory"stores settings like speaker volume, the default display, and other settings that your Mac typically uses. Resetting the NVRAM can fix problems wherein your MacBook Pro isn't playing sound, the display is flickering or turning itself off, the computer is taking too long to start up, and similar problems. On some Macs, "NVRAM" is replaced with "PRAM" ("Parameter Random-Access Memory"), which is fundamentally similar to NVRAM. Click the Apple logo in the top-left corner of the screen. A drop-down menu will appear. It's at the bottom of the Apple menu. Doing so prompts your MacBook Pro to shut down. To reset NVRAM, you'll have to hold down the Command, Option, P, and R keys all at the same time for about 15 seconds. Press the "Power" {"smallUrl":"https:\/\/www.wikihow.com\/images\/5\/5d\/Windowspower.png","bigUrl":"\/images\/thumb\/5\/5d\/Windowspower.png\/30px-Windowspower.png","smallWidth":460,"smallHeight":460,"bigWidth":"30","bigHeight":"30","licensing":"<div class="mw-parser-output"><p>I edited this screenshot of a Windows icon.

Do this immediately after pressing your Mac's "Power" button; you'll need to be pressing all four keys at once before the Apple logo appears. If the Apple logo appears before you press the keys, you'll have to shut down and try again. Your Mac may reboot itself during this process. Once you arrive at the user selection screen, you can release the keys and sign into your MacBook Pro like you usually do. You may need to reset some of your preferences (e.g., preferred audio output) after resetting the NVRAM. If you are still having issues with the system settings, you may need to factory reset your MacBook Pro. You will lose any data that you have saved on the MacBook if you do so.
Summary: Understand what resetting NVRAM will fix. Open the Apple menu . Click Shut Down. Click Shut Down when prompted. Find the NVRAM reset keys. Turn back on your Mac. Press and hold the NVRAM reset keys. Continue holding the keys until your Mac finishes starting up. Verify that the problem has been resolved.
