Charge Your MacBook with the Right Power Adapter

If you lose or break the power adapter that came with your MacBook Air or MacBook Pro, make sure to replace it with a charger that meets or exceeds the machine’s required wattage. A charger with too low a wattage may result in little or no charging (or even battery drain while working), and it certainly won’t enable fast charging. You can check the adapter’s wattage by reading the fine print on the charger itself, or by opening the System Information app (in the Applications/Utilities folder) and checking the AC Charger section in the Power screen. It’s safe to use an adapter with a higher wattage than required, but we don’t recommend going below the wattages of Apple’s included adapters:

  • 13-inch MacBook Air: 30 or 35 watts standard, 67 watts for fast charging
  • 15-inch MacBook Air: 35 watts standard, 70 watts for fast charging
  • 14-inch MacBook Pro: 67 or 70 watts standard, or 96 watts for the Pro and Max chips, 96 watts for fast charging
  • 16-inch MacBook Pro: 140 watts for both standard and fast charging

Social Media: Lost your MacBook charger? Don’t grab just any USB power adapter—using one that’s too weak can result in no charging, glacial charging, or battery drain while you work. Here’s the minimum wattage you need for each MacBook model.

    Last week a typo slipped by our proofers. Command+M is not open a new document but that command is Command+N. Sorry about that. To make up for it here are a couple more keyboard combinations you might find handy:

    **Command-Option-Esc** – If an app stops responding, you might need to force it to quit. You can do that with a right click on the app icon in the dock, but it’s even easier if you hit this keyboard shortcut. This will bring up the Force Quit dialog, which you can then use to make that non-responsive app quit. You might need to Command-Tab you way out of an active frozen app first, though, or use **Command+Shift+Option+Esc** to quit the currently active app.

    **Command-Option-P and R** – Here’s one that might challenge your fingers dexterity. Fortunately, you will hardly ever have to use it but it is used to reset your non-volatile random access memory (NVRAM). Information stored in NVRAM can include speaker volume, screen resolution, start-up disk selection and recent kernel panic information. If you are asked to reset your P-Ram or NVRAM here’s how you do it.

    1) Shut down your Mac
    2) Turn on your Mac
    3) Immediately after you hear the start up sound, hold down the command, option, P and R keys
    4) Hold those keys down until you hear the start up sound again and then release them.

  • _Dear Friends,_

    I tuned into the Apple special “Let Us Loop You In” event on my Apple TV. We will talk about the new hardware and software but there were a few things that caught my attention that really help to define Apple as a truly different company.

    The first was Apple’s environmental commitment. They now boast that 90% of their operations, worldwide, are powered by renewable energy and 100% in the USA. This is a unique accomplishment that is made even more remarkable by Apple’s size. While Small Dog Electronics is proud to power our Waitsfield headquarters and S. Burlington store by solar energy, we have not yet reached the point of powering all our operations which is something Apple has done both by purchasing renewable energy and installing large scale solar arrays at their locations both in the USA and China.

    Their environmental commitment goes further with an awareness of the impact their products have on the waste stream. They made a point to describe the materials used which have lower impact and talked about their recycling program, too. The robot, Liam, that disassembles iPhones into its component parts was very cool and is a further demonstration of Apple’s leadership in environmental stewardship.

    The other part of the announcement that caught my eye was the extension of Apple’s altruistic Research Kit tool that has helped researchers gather data on several chronic diseases. CareKit takes that a step further, offering tools that help patients and their medical providers manage those chronic diseases. They already have several new apps in development, including one that provides post-surgical care monitoring and another for diabetes monitoring. Research Kit and CareKit are both open-source software that do not necessarily provide any revenue stream for Apple but provides the tools to improve health. I am very proud of Apple for its initiatives in these areas.
