Macbook running slow

Several things to try ...

-- Remove all login items in System Preferences > Users & Groups > Login Items then restart to test.

-- Not enough available disk space can slow your Mac down. Click the Apple  top left in your screen. From the drop down menu click About This Mac > More Info > Storage

Make sure there's at least 15% free disk space. OS X Tips Where did my Disk Space go?

-- If it's not a login items or available storage space issue, errors on the hard drive can slow the system down.

Launch Disk Utility located in HD > Applications > Utillities

Select the startup disk on the left then select the First Aid tab.

Click: Verify Disk (not Verify Disk Permissions)

If Disk Utility reports errors, restart your Mac while holding down the Command + R keys.

From there you should be able to access the built in utilities in OS X Recoveryto repair the startup disk and restore OS X.

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.
