Macbook Pro STOPPED CHARGING after upgrading to Catalina 10.15.5

If it refuses to charge with the correct power adapter, the first line of defense is an SMC Reset:

How to reset the SMC of your Mac - Apple Support

If it still refuses to charge, use the "contact Support" link at the top of every forum page.

I also retried setting the SMC, and it only worked once, to no avail...but shutting off the battery health management option worked like a charm! Thanks SOOOO much, lapamdg, this was most helpful and an excellent observation and suggestion!

I started having this issue a couple days ago, MacBook Pro 16 (3-4 months old) Catalina 10.15.5, not sure what date it updated. working with tech support, we thought it might be the power supply, the replacement came in the mail today, and same problem. What I am able to do is the following. 1 disconnect charging cable from MacBook 2. unplug charger from outlet. 3. remove the kangaroo Jack (the piece that connects to the power supply with the prong for the outer. 4. reconnect kangaroo jack, 5, plug into outlet, 6 plug into computer. This works, but if you unplug anything, I have to repeat the whole process.

SMC Reset momentarily reduces the residual charge to Zero, resetting every chip inside your Mac, especially the System Management Controller (SMC). So, NO, it does not require any residual charge, but it DOES take following the procedure in the article religiously.

NB> the keys with the same labels, but on the other side of the keyboard, are not wired-in, and will not do the job.

FWIW, ever since I unchecked battery health management option, my battery has charged up and I haven't encountered the fault again. I really don't think this is a hardware issue since it started happening after the 10.15.5 update. It's just too much of a coincidence.

I had this problem too, on a three-month old MacBook Air. The battery stopped charging when I upgraded to macOS 10.15.5. The problem went away when I upgraded from macOS 10.15.5 to 10.15.6. It appears to me that there was a bug in the version of macOS that introduced the "battery health" function in System Preferences.

So I made another appointment at a different Genius Bar. The tech looked at it and said nothing wrong with USBC it is the battery - it is expended. I broke down bought a replacement battery for 60 and replaced myself - problem is noe resolved os battery was the issue - still does not answer what the battery was dead after 129 cycles.

The battery requires service. The battery is not functioning normally, though you may not notice a change in its behavior or the amount of charge it holds. You can continue to use your battery before it’s checked without harming your computer.

Contact Apple or take your computer to an Apple Authorized Service Provider or Apple Retail Store to determine which service and support options are available.

Started happening to my 2017 macbook pro 15inch as well. Resetting smc, pram don't help. Turning battery health management on and off, and plugging it in and out of power remedies the problem for me - for now. I hope we get a fix for this soon.

This is such a hassle.

No need to visit a store.

The folks reachable at the "Contact Support" link (at the top of every forum page) can arrange to send you a shipping box and have your Mac sent to a regional repair depot for further evaluation and repair.

From your description directly above, you MacBook Pro and charging system appear to be operating completely as designed.

The MacBook Pro can use up to the full amount of power provided by the power adapter, and under heavy load, will freely "borrow" power from the battery as well. Your MacBook Pro CAN be run solely on battery, but it WILL run slower in most cases when run only on battery. It is also expected that when you connect an external display (almost all of which require AC power) you will attach the power adapter as well.

Since a charge cycle is ever-so-slightly destructive to battery longevity, your Mac will not initiate a charge cycle until the battery level declines to about 92 percent level. Then it will start a charge cycle to top off the battery back to nearly 100 percent level.

Based on your use patterns, The new Battery Health Management feature in 10.15.5 may relax those limits a bit to provide better battery long-term health at the cost of shorter run time on battery.

Unclick everything in the "energy saver" except "Show battery status in the menu bar" at the bottom.

This made a huge difference.

After doing this, my laptop is not crashing anymore

No. It is not a battery issue since in my bootcamp, my battery is charging. While in my MAC OS, it is not. CATALINA IS BUGGY AS ****! and it infuriates me
