Slow start power button

On all my previous iMacs (used or new) when the power button was pressed for just 2-3 seconds the Mac started up but this latest used iMac takes 8-15 seconds. I have had power supplies die before but they would just quit-- period! Any words of wisdom appreciated

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.

Before Resetting the SMC

Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.

Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.

Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve

Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

NVRAM reset:

Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.

Sorry for taking so long to reply. Your step one seems to have done the trick so will press on. Thanks for the help.

Hi John

I am having the same issue in my iMac 27inch late 2013 model. I tried all the methods but still having the same issue.

Please help, I am worried because I have got apple protection plan which will be going to expire in mid july and dont want to spend my savings on any hardware.

Is there any hardware problem?

Thanks in advance!

Please reset the SMC and PRAM and then re-test. If the problem persists restart in Safe Mode and if the does not work please post a EtreCheck report of your system. Below are links for instructs to the various resets.

There are several major issues, the first is you or someone that has access to your computer has installed CleanMyMac which is considered malware by most experienced users. Locate the developers uninstall instructions and uninstall it immediately. Mac OS was designed from it's very onset to be very secure and does not need any cleaning, antivirus, or ANY third party "maintenance" apps. If kept up-to-date and otherwise left alone Mac OS runs reliably for years for most users.

The next item shown in the report is you have some apps that have left orphans, locate in the EtreCheck report where it says to remove them and follow the on-screen directions.

Finally you have a large amount of software installs that are 100% unnecessary, for example there is no need for any of the Canon apps. Everything they do is already built into Mac OS!

You have also have a large amount of Internet Plugins, get rid of the ones you don't need. One I find very suspicious is Adobe Pepper Flash Player. If you don't know how please read Safari 8 (Yosemite): If you need to remove a plug-in

Finally you have too many startup items and that needs to be fixed. You can do that in System Preferences - Users & Groups - Click the user and click the Startup tab and remove the unnecessary startup items.

I have deleted all the unnecessary items but still have the same issue
