If your Mac is acting sluggish or behaving strangely, resetting the SMC and PRAM can often breathe new life into your machine. These resets help resolve hardware and system settings glitches that could be causing performance hiccups. The process is straightforward and can restore your Mac to optimal functioning without the need for complex troubleshooting.
In short, resetting the SMC (System Management Controller) and PRAM (Parameter RAM) can fix common issues like unresponsive hardware, battery problems, and startup errors. This guide will walk you through simple steps to perform these resets, helping you get your Mac back to peak performance quickly.
When your Mac starts feeling slow, unresponsive, or shows unusual behavior, it’s easy to get frustrated. Sometimes, these problems aren’t caused by software but by minor hardware or settings issues stored in the SMC and PRAM. Resetting them can clear out glitches and restore normal functioning. Performing these resets is a quick, effective troubleshooting step that can save you time and avoid unnecessary visits to the Apple Store. Whether you’re using an Intel-based Mac or a newer Apple Silicon model, knowing how to reset the SMC and PRAM is a handy skill to have in your tech toolkit.
How to reset SMC and PRAM during performance issues
If your Mac is acting slow, freezing, or experiencing odd behaviors, resetting the SMC and PRAM can often help resolve these problems. These resets clear some of the temporary data stored in your Mac’s hardware and settings, potentially fixing performance problems.
Understanding the purpose of SMC and PRAM resets
The System Management Controller (SMC) manages hardware functions like power management, battery, keyboard, and thermal management. Resetting the SMC can fix issues related to these hardware components.
The Parameter RAM (PRAM) stores system settings such as display resolution, sound volume, and startup disk information. Resetting PRAM can resolve problems linked to these settings that might cause your Mac to run slowly or behave unexpectedly.
Signs your Mac might need an SMC reset
- Unusual battery or power issues
- Fans running loudly without reason

How do I reset the SMC on a MacBook with a T2 chip?
To reset the SMC on a MacBook with a T2 chip, shut down your MacBook. Press and hold the power button for 10 seconds, then release it. Wait a few seconds, then press the power button again to turn on your Mac. If this doesn’t work, connect your Mac to its charger, then press and hold the right Shift key, the left Option key, the left Control key, and the power button for 7 seconds. Keep holding these keys while you release the power button, then wait a few seconds before turning your Mac back on.
What should I do if resetting the PRAM doesn’t resolve performance issues?
If resetting the PRAM doesn’t improve your Mac’s performance, consider resetting the SMC as well, since they control different hardware functions. Additionally, check your system storage for any full disks, close unnecessary applications, and run Disk Utility to repair disk permissions. Updating your macOS to the latest version can also help eliminate software-related issues affecting performance.
Can resetting the SMC affect my system settings or hardware configuration?
Resetting the SMC restores certain hardware settings to their default states, which can resolve issues like power, battery, or thermal management problems. However, it doesn’t erase personal data or affect your system’s configuration permanently. After the reset, some preferences might need to be reconfigured, but your files and applications remain intact.
Are there any risks associated with resetting the PRAM or SMC?
Resetting the PRAM or SMC is generally safe and helps troubleshoot hardware and performance problems. While these resets restore default system settings, they typically do not cause data loss or hardware issues. It’s a standard step recommended by Apple support when encountering persistent system problems, but always ensure your data is backed up to prevent potential data loss from other issues.
