Apple on Wednesday unveiled three firmware updates designed to address issues with older batteries in its MacBook line of laptop computers. The updates are aimed at the MacBook Pro, the MacBook. Put the battery in, and boot your computer while holding the Command + Option + P + R keys to reset the parameter RAM. Wait for the chime to sound three times. Release the keys and shut down the computer. Remove the battery again, and reinsert the RAM module. Put the battery back in. Boot up your Mac, and you should not see the firmware lock again.
NVRAM (nonvolatile random-access memory) is a small amount of memory that your Mac uses to store certain settings and access them quickly. PRAM (Parameter RAM) stores similar information, and the steps for resetting NVRAM and PRAM are the same.
Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.
If you experience issues related to these settings or others, resetting NVRAM might help. For example, if your Mac starts up from a disk other than the one selected in Startup Disk preferences, or a question mark icon briefly appears before your Mac starts up, you might need to reset NVRAM.
How to reset NVRAM
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart.
- On Mac computers that play a startup sound, you can release the keys after the second startup sound.
- On Mac computers that have the Apple T2 Security Chip, you can release the keys after the Apple logo appears and disappears for the second time.
If your Mac is using a firmware password, this key combination does nothing or causes your Mac to start up from macOS Recovery. To reset NVRAM, first turn off the firmware password.
When your Mac finishes starting up, you might want to open System Preferences and adjust any settings that were reset, such as sound volume, display resolution, startup disk selection, or time zone.

- If you're using a desktop Mac instead of a notebook, and settings such as sound volume or time zone are reset every time you shut down and unplug your Mac, you might need to replace the battery inside your Mac. This small battery is on your computer's logic board, and it helps NVRAM retain settings when your Mac is unplugged. You can take your Mac to an Apple service provider to replace the battery.
- If you experience issues with sleep, wake, power, charging your Mac notebook battery, or other power-related symptoms, you might need to reset the SMC (System Management Controller).
About the lithium-ion battery in your Mac notebook
Mac notebook batteries use lithium-ion technology. Lithium-ion batteries charge quickly, are long-lasting, and currently provide the best technology to power your computer.
All rechargeable batteries are consumable components that become less effective as they get older—and their age isn't determined only by time. A battery's lifespan depends on its chemical age, which is affected by factors such as its temperature history and charging pattern. As your notebook's battery ages chemically, its charging capacity gets smaller.
With these tips for maximizing battery performance, you can get the most out of all your Apple devices. And with battery health management, your Mac notebook can take battery optimization even further.

How battery health management helps

The battery health management feature in macOS 10.15.5 is designed to improve your battery's lifespan by reducing the rate at which it chemically ages. The feature does this by monitoring your battery's temperature history and its charging patterns.

Based on the measurements that it collects, battery health management may reduce your battery's maximum charge when in this mode. This happens as needed to ensure that your battery charges to a level that's optimized for your usage—reducing wear on the battery, and slowing its chemical aging.

While battery health management benefits your battery's long-term lifespan, it can also reduce the amount of time your Mac runs on one battery charge when capacity limits are applied. If your priority is making your Mac notebook last as long as possible before recharging, you can turn the feature off.
When battery health management is turned on, your battery's maximum charging capacity might be limited. Although the feature is designed to improve your battery's lifespan, the limited maximum capacity might update your battery status menu to indicate a need for service.
How to control the battery health management feature
Battery health management is on by default when you buy a new Mac notebook with macOS 10.15.5, or after you upgrade to macOS 10.15.5 on a Mac notebook with Thunderbolt 3 ports.
