It looks like a problem with energy administration in macOS 15.2 after the replace. Right here’s what you’ll be able to strive:
1. Reset SMC and NVRAM
These resets typically repair surprising energy and sleep points. Right here’s how:
SMC Reset:
Shut down your MacBook.
Press and maintain Shift + Management + Choice on the left facet of the keyboard and the ability button for 10 seconds.
Launch all keys and switch your MacBook again on.
NVRAM Reset:
Flip off your MacBook.
Flip it again on and instantly press Choice + Command + P + R on the similar time.
Maintain holding the keys for about 20 seconds, then launch them if you see the Apple brand or hear a second startup sound.
2. Verify and Disable Wake Requests
Wake requests are duties that trigger your Mac to get up throughout sleep. To test them:
Open Terminal (you will discover it by looking in Highlight).
Run the next command:
pmset -g log | grep -i "Wake Requests"
This can present you which of them processes or apps are waking the Mac (e.g., mDNSResponder, powerd).
To cut back pointless wake requests:
Go to System Preferences > Battery > Choices.
Flip off Wake for community entry.
Disable app notifications which will set off wake requests, reminiscent of Calendar updates or background duties.
3. Replace macOS
Verify for software program updates in System Preferences > Software program Replace. Apple could have launched a patch to repair this concern.
If none of this works, it is perhaps value contacting Apple Help for additional help.
