• Wi - Fi pass drops after iMac sleep mode

  Help, please. I had a lot of Wi - Fi problems after upgrade to Yosemite. I know that many others have had similar problems and the Genius bar was not able to find a solution. I get the same "I never heard of this problem before" and then run simple diagnostic tests. Here are some features:

  -iMac 21.5 "2011 Office

  -OS X Yosemite 10.10.5

  -Have had problems with connectivity Wi - Fi based on the current version works, but the worst problems came with Yosemite

  -iPad 2, Asus computer laptop and HP printer work fine. I tested the Modem and the router, they work well

  The problem: after my iMac Sleep Mode wake up my network connection is interrupted. I have to physically click the Wi - Fi connection and wait it is the signal (it takes about 30 seconds). It is not a big problem, but it becomes very frustrating after what happens every time. I have other users in households who also have this problem and they are not very good with the iMacs.

  Someone had this problem and was able to remedy?

  Thank you in advance,

  Scott

• Sierra of iMac (late 2009)

  I started to download the new operating system last night and it is still downloading (3.54 GB of 4.77 GB).  Whats up with the length of time to download?

  Hello vegasdad,
  Thank you for using communities of Apple Support.

  If I understand your message that she was taking a longer than usual time to download the macOS Sierra update for your iMac. I understand your concern about the time it takes to download a software update. To try and speed up the process, you can stop the current download and place the installer in the trash. Then empty the trash. Restart your iMac and open the App Store to the Sierra to macOS page. Click on the button download and see if the download is just faster for you.

  Best regards.

  A secondary question is why does have the external USB drive go upward because some accessible a network port?  Nothing on the disc has been consulted.

  Thank you!

  My iMac has constantly made call sleep and wakes up on the screen every 15 minutes approximately.  I ran the "journal of the pmset g" Terminal command and tries to interpret the results.

  May we with a Mac post well behave the terminal results in "Journal of the pmset g" so I can see what looks like a normal output?  It will help me to get a better idea of what's different in my results.

• IMac sleep update af 2016-004

  After that I applied yesterday the security fix for 2016-004 to my Imac (dec 2010 model) I can not enter the mode 'sleep'.  I tried to do a safe boot (found a note on the net, that it has solved the problem for some) but this isn't for me

  When I try to use mode 'sleep' - the screen turns white as usual and my external USB drive turn off - but I sounds like the fan in the Imac does not turn down. After a few minutes it back on the screen

  Until yesterday, everything worked very well - and the update of security is the only change that I made

  Any ideas?

• My iMac sleep

  I have an iMac 27 "end 2015 a few weeks ago, and the sleep function worked fine. But all of a sudden yesterday, he refuses to go to sleep. I used to use the shortcut keyboard option + command + eject, but it does not work. The screen just turns off. Then I tried to choose "sleep" from the Apple menu, but the same thing. The screen turns off, but the drive never turns down. I know it's not instantaneous, but I leave 30 seconds and it will not turn it down. It continues to run until I have press a key or click the mouse. Already, I went through the evolution of the system preferences. Nothing is shared by the computer. "Wake for network access" is disabled. 'Allow Bluetooth wake up' is disabled. My keyboard is a USB Apple wired one. I quit all programs and applications and it will not sleep. I moved the cursor "display off" from 10 minutes to 1 and then back to 10 minutes. I left alone; the screen is off, but the disks never turned down after several hours. If I want to leave for a while, I let the music so he can't SLEEP. But for the last test, no music was played. I checked if something prevented from sleep in the activity monitor, but they are all the 'no '. Energy saving, "Prevent computer to sleep automatically when the screen is off" is not checked. "Put hard drives to sleep when possible" is checked. I use the same settings I used for on an another iMac. It's very frustrating because it was working fine the other day. I turned off the computer and unplugged it overnight and it will not sleep. Anyone know what is happening?
