El Capitan is slow???

Apple does this thing where after your battery reaches a certain age or a certain number of charges they underclock your CPU by abusing Intel's SpeedStep functionality.

This is why the batteries are non-replaceable. Apple isn't a charity organization.

Here's how to disable it: http://www.rdoxenham.com/?p=259

Post a link to something from Apple that confirms that please.

My Mac Mini 2014 was ok with Yosemite, now on El Capitan is running very slow, looks like the hard drive is always looking for something (it remember me when I was on Microsoft Windows :(((( ). I have already cleared Nvram, smc, disabled SIP, disabled Spotlight, reenabled spotlight, reindexed the hard disk, cleared cache, created a new user, updated El Capitan with all the latest beta release 10.11.1. Nothing works, I think that if you have an SSD you can really notice the differences, but with a mechanical disk El Capitan respond very slow compared to Yosemite. I think I will downgrade to Yosemite.

You really should start your own thread for your problem rather posting on the bottom of someone else like this.

Why is that, the threat is about how El Capitan is slow for someone, I just added my experience. I am following any post about El Capitan problem, developers too.

Working two problems in the same thread is a good way to get everyone confused.

If there is a thread you think is important link to it from your own thread.

Besides if you start a thread you can award point to those who help you and close it by marking it solved. Whereas you can do none of that on this thread.

Thanks, This article was written in 2012 and I have a 2014 Midyear MBP with Retina. I'll be patient and wait for a point release non-beta. The funny thing is I was a beta developer tester and those ran better than the final public release.

Reinstalled Yosemite and the Mac Mini is fast again. I don't know what else to try on El Capitan.

Curious how you determined El Cap is slow due to the number of external drives. My El Cap is slow on an early 2009 iMac with 8 GM RAM, and I have a bunch of external drives (most FireWire, some USB), but I didn't suspect that the slowness was a function of the number of external drives.

GO into system preference, security & privac, click on FileVault...

I'll bet there is a status bar showing it's encrypting.

that was a default selection when it set up your computer after installing "El Capitan"…

i suspect everything is going to be slow until it is done.

I started unplugging drives. Notice "andrewfromquakertown" below. I believe this was one of the issues. The other was the indexing of the drives. Now that all the drives have been indexed and I suppose encrypted, the issue isn't present. I have a 4Tb drive that causes slowness when plugged in. This drive is used with a "Time Machine" backup and many other items. I believe it is updating the index when it is plugged in. Having dropbox, one drive, etc. hooked up as well external drives all contributed to the spinning pinwheel when El Capitan. Also, the "fire vault" encryption as mentioned.

The 10.11.1 update has improved things for me considerably.

Hey Andrew,

Thank you for this, I am running El Capitan on a Macbook Air (mid 2013) alongside Office365 and my computer is going dog slow, is it ok to disable this or will it have any contra effect on the new OS?

Thanks again
CJ

You can disable it and it won't have any ill effects on the operation of your computer, HOWEVER, it's likely to be slow while it Decrypts what it has already encrypted. So if it's more than half way through the process, you may as well let it finish. If somebody hasn't upgraded yet, they may want to deselect those check boxes when they pop up during the initial restart.

Once the process finished (took all day for me), my 2 Macs running it are plenty fast. It also turned off the "dashboard" feature which can be turned back on in the system preferences..

The slowing may have to do with HD memory. OS 10.11.1 isn't a top performer when free mmory drops below 15% on my MBP, which is about 75GB with a 500GB HD. Curious if SSID users have detected slowing. HDs are the weakest component on Macs. Where Apple cuts corners to save a few bucks.
