Check Battery Cycle Count On A Mac Laptop

If you have a Apple MacBook, MacBook Air or MacBook Pro, you can check the battery cycle count to get an idea of overall battery health. Here’s how you can do that yourself, right from the macOS built in system management functions.

This works for all batteries in Mac laptop models.

• Pull down the () Apple menu and choose “About This Mac“.
• Click the “System Report…” button.
• Under Hardware, select “Power” and look for “Cycle Count” under the “Battery Information” portion.

The number shown is the cycle count of the current battery. A battery charge cycle is when the battery has been drained to 0% and then refilled to 100% of it’s maximum capacity. Knowing the cycle count is helpful if you suspect your battery is having problems retaining a charge. Apple says new notebook batteries are designed to retain 80% of original capacity after 1000 cycles. If your battery is performing at less than expected and is still under warranty, it may be a good idea to schedule an appointment with an Apple Genius.


Prevent Discovery Of Your Mac

Your Mac is pretty safe on your private home network, but what about when you’re surfing the Web in airports or coffee shops? Anyone with a computer and rudimentary hacking skills could target you, which is why it’s important to make sure your Mac’s built-in Firewall is enabled and that stealth mode is turned on.

Apple’s macOS Firewall feature blocks unwanted network traffic coming into your computer, and stealth mode makes your Mac essentially invisible to hackers snooping for computers to target. They aren’t foolproof features, but they will keep most people from finding and attacking your Mac on public networks.

First, you need to make sure your Mac’s Firewall is enabled:

• Go to () Apple menu > System Preferences.
• Choose Security & Privacy.
• Select the Firewall tab.
• If the Firewall is active you’ll see a green dot and “Firewall: On.” If not, click Turn Firewall On. You may have to click the padlock icon and authenticate with your Mac’s password to change the setting.

Next, enable stealth mode:

• Click Firewall Options. It’s below the button for turning the Firewall on and off.
• Check Enable stealth mode.
• Click OK.

Automatically allow built-in software to receive incoming connections” and “Automatically allow downloaded signed software to receive incoming connections” should already be checked. Those settings let the apps you already have communicate through the firewall without you having to take any extra steps. Leave those checked unless you know what you’re doing and plan to manage app network access manually. You should leave “Block all incoming connections” unchecked too, unless all you’re doing is surfing the Web.
