• iMac won't restart or shut down after having been 10.11.5

  He said title. My iMac was fine before the update came through yesterday. I went to reboot tonight because the RAM used was realllllly high and I thought a solid reboot after update from yesterday could be a good thing (don't ask why - just my logic)... and surprise! -He has authorized the menu bar and leave viewfinder, but would not closed at all. I could always use the dock to load and use applications. I saw another thread that mentions deleting stuff from Wacom. I went and emptied all of my items found from Wacom. Still will not be closed. I have reset several times VRAM. I can do a forced shutdown, and he'll sleep ok. Activity monitor shows nothing super weird, even if it always shows Wacom and Tablet drivers running.

  Anyone else running into this? Or have an idea?

  Please?

  Hello..

  Safe Mode boot removes the system caches that can help after an OS X day or level.

  Upper left corner of your screen, click on the Apple  > Shut Down.

  After your Mac stops, wait 10 seconds, then press the power button.

  As soon as you hear the startup tone, hold down the SHIFT key. You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

  Release the SHIFT key when you see the gray Apple logo and progress indicator.

  Once you are in Mode without failure, return to the menu Apple . In the drop-down list, click: reboot

• iMac 27 in late 2012 is running extremely slow

  iMac 27 "Late 2012 3.4 Ghz Intel i7, 16 GB ram, of v10.11.2

  As soon as started in the morning, analyses of my iMac to launch any application especially Adobe CC apps.

  Mail and Safari is too slow. I use illustrator for my work and it takes several forced to work at all.

  5 minutes to start this single app. All I see is the spinning wheel of death.

  Would be - that the HD is dying, how can I check.

  I wish I could help, but if it's any comfort, I am having similar problems.  I have an iMac 21.5 ", end of 2012 with a 1 TB hard drive hybrid.  Often, I get the spinning beachball and it seems to have originated after that El Capitan has been installed.  In addition, the activity monitor will show often Reader Adobe flash (version 20) does not.  Then I have to force quit the flash player in order to free the computer.  I tried to contact Adobe, but they do not seem interested in helping without getting paid.  I can only hope that between Adobe and Apple, someone will provide an update that resolves the problem.

• My 2013 iMac 27 inch runs very slowly

  My iMac (27-inch, late 2013, with a 3.2 GHz Intel Core i5 processor) has been gradually slowing down for a while. I get the dreaded beach ball a lot, sometimes by what seems to be really simple things. Today I left it on when running only Safari. I woke up, I got a message from the system that I was running on the memory of the application and must force quit some applications. With 24 GB RAM available, which didn't make sense to me (I had recently installed 16 GB of RAM (2 x 8) OWC in addition to the original 8 GB (2 x 4), for a total of 24 GB of memory).

  I am running OS X El Capitan (10.11.2). I think I can inadvertently installed some malicious programs. AppleCare is still in force.

  As conditions gradually got worse ovewr the past few months, I tried:

  • Drive 4 Pulse, indicating, I had critical hardware issues, but I never got their thing Bootwell to work, even with the help of their support team. They recommended that replace the hard drive.
  • Apple support. Thay suggested I run Apple Diagnostics, but when he finds nothing wrong, they couldn't do anything. At the time it wasn't that bad and I didn't really drag a 27-inch iMac down to the Genius Bar for help.
  • SpeedTools Utilities Pro. It seemed easier to use than driving impulses. Running a live scan, he finds 54 501 bad sectors on my hard drive of 1 TB. But still, nothing showed on Apple Diagnostics.

  After watching a few discussions re slow iMacs support group today, I learned EtreCheck, downloaded and ran a report. I'll post as a suite.

  My memory really once again, so I am posting this today.

  "Clean apps" or "speed boost" utility are scams, so I would remove such software.

  Please post this report EtreCheck when you get a chance if anyone can help identify a culprit for the slow downs.

• iMac will not shut down or restart...

  I have an iMac 27 "end 2012, running El Capitan 10.11.5 and since the last update to version, it will not shut down or restart. I tried unplugging the power for about 10 minutes, but that didn't work... any notice or is this just a glitch in the latest update?

  Your office is frozen?   If not, stop or reboot can wait for something to finish - you close all open applications?   Allow you your system to connect to the internet (these pesky background downloads or you are not always aware of synchronization)

  As for hard shutdown - with button / stop

  Have you held in the power button for about 15 seconds to stop hard - otherwise he's asleep.

  After unplugging - press and hold the power button in for 15 seconds to evacuate the power of mac - that can help.
