My iMac periodically will not allow entries onto websites, nor will it allow searches in Safari. Specifically, when I turn it on or reboot, the system works as designed. However, after it has been on for a few hours, it no longer permits me to login

Repair permissions & restart your computer. If that does not work, then disconnect all devices from your comp & do the following:

Boot up from your computer by holding down the command+r keys. This will take you to the recovery drive.

Select Disk Utility & hit Return.

In Disk Utility select the HD on the left & click on Repair Disk (bottom right).

When you reach the desktop after doing the above, again repair permissions & restart your computer.

When you notice the problem, 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 one 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.

If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.

This is my problem but I'm using El Capitan 10.11.5 and support says I no longer need to repair my permissions.

I'm not very computer literate but will be glad to try anything that is "followable." Thank you for any help
