Feb 9, 2016 10:59 AM in response to gabiG3by Kappy,Try this:
Boot the computer into Safe Mode, then restart normally. This will be slower than a normal startup.
Intel-based Macs: Resetting the System Management Controller (SMC)
Resetting your Mac's PRAM and NVRAM
Repair the Hard Drive and Permissions - El Capitan
Boot to the Recovery HD:

When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the indented Macintosh HD entry from the the left side list. Click on the First Aid tab in the toolbar.. If Disk Utility reports any errors that have been fixed, then re-run First Aid until no errors are reported. Wait until the operation completes, then quit Disk Utility and return to the main menu. Select Restart from the Apple menu.
Now, Download and Reinstall OS X El Capitan 10.11.3 Combo Update.

Feb 9, 2016 2:33 PM in response to gabiG3by Linc Davis,This procedure will delete some cache files. The files are automatically generated and don't contain any of your data. Occasionally they can become corrupt and cause problems such as yours.
Please back up all data.
Triple-click anywhere in the line of text below on this page to select it:
open $TMPDIR..
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal 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.
Paste into the Terminal window by pressing command-V. Depending on which web browser you use, you may have to press the return key. A folder with a long, random name should open. Inside it, there should be a subfolder named "C". Drag that to the Trash.
Log out or restart the computer. Empty the Trash. Test.

Feb 10, 2016 3:05 AM in response to Linc Davisby gabiG3,Hi - was just about to try this, when I encountered fresh ****: Wanted to do the back-up first using my WD My Passport for Mac, which I have used perfectly well up to now and, post El Capitan, there is no longer a back-p option available in the 'My Passport' menu (I can open, eject, copy etc, but not back up). Any idea why that may be? Don't want to do anything until I've done a successful back-up.... So wish I hadn't done the upgrade... Thanks!

Feb 10, 2016 3:15 AM in response to gabiG3by lllaass,Are you using WD's Passport software?
Maybe it has to be updated for EC.

Feb 10, 2016 3:24 AM in response to lllaassby gabiG3,Am using WD "My Passport For Mac" external drive. Worked fine with Yosemite, now no longer. When you say 'upgrade' what do you mean?

Feb 10, 2016 3:27 AM in response to lllaassby gabiG3,Sorry - the question was "when you say 'update', what do you mean?"

Feb 10, 2016 3:49 AM in response to gabiG3by lllaass,Go to WDs site and look for updated software for Passport bckup

Feb 10, 2016 3:58 AM in response to Linc Davisby gabiG3,PS - the My Passport Format info shows: Mac OS Extended (Journaled) - don't know if that helps....

Feb 10, 2016 5:20 AM in response to gabiG3by Linc Davis,It sounds like you're using WD's software to back up. I don't know anything about that software and I wouldn't trust it with my data. I suggest that you follow the instructions linked below.
Use Time Machine to back up or restore your Mac - Apple Support

Feb 10, 2016 6:22 AM in response to Linc Davisby gabiG3,No, I've always used Time Machine to do the back-ups - always worked fine under Yosemite. Now the external drive is read only.... This seems to be happening to quite a few people post El Capitan (some WD, some Seagate, some Toshiba...) - not sure whether it's an Apple or drive providers' problem, but El Capitan is the common denominator.... Thank you anyway for your suggestions - think I will lie down in a darkened room for a bit until someone comes up with a solution .

Feb 10, 2016 6:58 AM in response to gabiG3by lllaass,The Read Only problems you refer to occurred because the drive was formatted in the PC NTFS format that a Mac can't natively write to. So WD provided an app that allows writing to NTFS but the app did not work in El Capitan.
If you go to Finder and select the WD HD and right click and select Get Info what is listed in Sharing and Permissions?
Yo can change by click on the padlock at the bottom and entering Admin PW and changing

Feb 10, 2016 7:07 AM in response to lllaassby gabiG3,Hi - Share and Permissions say that I can "read and write'.
Also the Format info says "Mac OS Extended (Journaled)" not NTFS....
