My MacBook Pro is running slow after macOS 15.2 update

I'd backup, boot to Recovery mode, erase, and do a clean install. Then without any further 3rd party installs or restore use the stock apps and see if the problem persists. If yes, return or fix the Mac if it is new and under warranty. If not, re-install only known-good 3rd party apps one-by one and check if the system is OK before installing the next.

Or remove all 3rd party virus apps (Avast, AVG, Bitdefender, Intego, MacAfee, Norton, Kaspersky, ESET NOD32, Trusteer, PC Matic etc) and 3rd party "cleaning", "optimizing", "speed-up" apps (CleanMyMac, Cleaner One, MacKeeper etc). They produce obscure errors like this and are not needed.

An EtreCheck report would eliminate much guesswork:

Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?

Boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

Very often this is caused by having Full Keyboard Access turned on by mistake. Go to your Accessibility settings and make sure it is OFF.

I too am experiencing infrequent crash issues (3 total since installing), higher battery usage, and clock skew.

Issue started after updating to Sequoia 15.2
