Reset SMC
The System Management Controller (SMC) controls the power on your Mac. Resetting it can solve some uncommon issues related to power or temperature management.
Step 1. Determine if your Mac has Apple silicon
See if you have a Mac with Apple silicon
If you do:
- Check that your computer is connected to a reliable power source.
- Restart your Mac or shut it down and turn it back on.
Step 2. If it doesn't, determine if your Mac has a T2 chip

If you do:
Laptop computer with the T2 chip
- Shut down your computer if you can.
- Press the power button for 10 seconds, then release.
- Remember, all Macs have this button, even if you have TouchID — you can also use it to restart your computer.
- Wait for a few seconds, then press the power button again to turn your computer back on.
If the issue doesn't resolve:
- Shut down your computer.
- Press and hold Control (⌃)-Option (Alt) ⌥-Shift ⇧ — your Mac may turn on in the process.
- Continue to press and hold all the keys for around 7 seconds, then press and hold your Mac's power button without releasing the other keys — if your laptop is on, it will turn off during this step.
- Keep pressing the keys for another 7 seconds, then release them.
- Wait for a little while, then press the power button again to turn your Mac back on.
Desktop computer with the T2 chip
- Shut down your computer and unplug the power cord.
- Wait for 15 seconds then plug the power cord back in.

Reset NVRAM
The non-volatile random access memory (NVRAM), sometimes called the parallel random-access machine (PRAM), is a small portion of memory that your computer uses to save and have lightning-speed access to certain settings such as sound, startup-disk selection, and even the time zone. Most of the time you can control these settings in your System Preferences, but if you can’t, resetting your NVRAM may help!
If your Mac has Apple silicon
If your Mac computer has Apple silicon you don’t need to worry about resetting your NVRAM as these devices don’t include a manual reset option.
If your Mac is Intel-based
If your Mac doesn’t have Apple silicon, then your computer has an Intel processor and features an NVRAM reset option. Follow the instructions below to reset it.
- Shut down your Mac.
- Turn on your computer and immediately press and hold Option-Command (⌘)-P-R.
- You can release the keys after about 20 seconds — you may start to hear the restart sound a few times or see the Apple logo pop up on the screen.
- When your Mac does restart, make sure to readjust your system settings as they could have reset in the process.
- If these steps didn’t work, see these guidelines to continue troubleshooting.
Update your software
A software update is simply a newer version of your current macOS software. "Software Update" will install updates and upgrades for your operating system as well as any built-in apps.
Update the macOS on your Mac
- Before diving in, you should always back up your Mac just to be safe.
- Click the Apple symbol located on the left corner of the screen > "System Preferences" > "Software Update".
- It will check for new software available for your Mac:
- If your computer is up to date, you won’t need to do anything as your computer has already been updated.
- If there is new software available, click “Update Now” or “Upgrade Now” to install it — you may need to enter your password or restart your computer.
If "Software Update" doesn’t come up
- If you don't see "Software Update" in your "System Preferences" window, try using "Search" located in the corner and look up “Software Update”.
- If your macOS doesn't have "Software Update", go to the App Store and click the "Updates" tab to see if there are any updates available.
