El Capitan is slow???

Is anyone else having the issue of your Mac running wicked slow after the new El Capitan update? Word, Safari, Preview, and iTunes wouldn't open- they froze and I had to force quit them. Even typing this there is a major lag and the pinwheel appears. What's up with that? So far I hate how slow it's making my mac.

When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES All Messages

from the log list on the left. If you don't see that list, select

View Show Log List

from the menu bar at the top of the screen.

Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.

Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.

Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

I have that too. Since the last El Capitan beta (begin October) my mac runs as fast as a one legged donkey. I ran several times the disc utility for first aid. I dropped out of the beta program and installed the non beta El Capitan. No change. Now I am backing up the 350 GB to an external disk (150 hours to go). Then I will reformat that disk and install good old Yosemite. Hopefully that helps.

Since the install everything is slow and seems to invoke the dreaded spinning beach ball (which I do not like the new look of by the way). I am using a barely 1 year old MacBook Pro and since install of the new OSX it lags on simple things like changing a file name on the desktop. APPLE - fix this!!!! I hope this fix will be apart of the 10.11.1 release.

Apple is not going to fix it.


You are going to have to fix your MBP.


Waiting for an upgrade to the operating system to fix a problem with the computer is a false hope. Usually if the computer has a problem, upgrading the operating system will only make the problems worst.


If you provide us with more detail or download and install EtreCheck from http://www.etresoft.com/etrecheck


Run it and post the report here. Maybe that will show us where the problem is with your MBP.

I tracked down the performance issues as having something to do with external backup drives. Either the Thunderbolt display or something else. Since removing the external backup drives, performance is back up to par. Saving a file as a new file improved some performance aspects. It runs great now most of the time.
