Odd battery and fan issues after latest El Capitan RC

[orvn]

After the most recent update of El Capitan (Release Candidate 10.11.1) my machine (13” rMBP) has been behaving very oddly.

Anyone else seeing this?

1. It’s a lot slower all round, in terms of processing speed.
2. A process called “footprint” uses a significant amount of CPU resources (200% +) for the first 10 minutes of startup.
3. My fans are constantly on max RPM, from the moment the machine is switched on. Apps that report on fan usage and CPU heat (iStatPro and SMCfancontrol) are unable to pull this data anymore (they just say 0˚ and 000rpm).
4. My battery icon is gone from the menulets in the top right corner. My energy saver system preferences say my battery is at 0% (but I know it’s full and it’s running on battery power now).

Early Betas of El Capitan were great, but for some reason, this Release Candidate is performing very poorly (5 days before public release!)

10.11.1 is not a release candidate, it is the first beta update to the actual release candidate.
As an early beta of an update, there are bound to be these kinds of issues.

That makes sense. Would restoring from Time Machine be the best option?

It seems that all the internal sensors do not respond, e.g.-

• When I close the Macbook, it doesn't go to sleep, as if the magnetic sensor doesn't detect that the monitor is in the closed position.
• Unable to access any information about RPM or CPU temperature. It just reads 0.
• Battery icon gone and system prefs says battery is at 0%, when it definitely is not.

What are the chances a software update caused hardware damage? Practically non-existent?

I wouldn't know, I've never had to restore from any kind of backup, so I can't be sure if that will have the desired effect.

Software cannot cause hardware damage.

Sounds like textbook SMC issues. Do a reset.

Software cannot cause hardware damage.

It absolutely can if software/firmware is controlling how a piece of hardware deals with thermal issues.

Right, forgot about that when I made the comment yesterday.

No probs on my late 2011 MBP. Sounds like a bad update. Might want to reinstall.

@simon lefisch
That may not be necessary.
It seems to me to more likely be SMC issues easily fixed by an SMC reset as @SlCKB0Y pointed out.
