I agree. 4gb is "enough" but 6gb will make life better.

Go on eBay and check however what a more recent iMac is worth. There is not a lot of point in pouring money into a unit that is not worth all the extra it will cost you.

 

There are certain break points in the Mac models:

 

2009 is the oldest you can still install current versions of macOS.

 

Mid 2010 can install 32gb of RAM in 27".

 

Mid 2011 First Macs to have Thunderbolt and can connect 2nd monitor

 

Late 2011 last 21.5" iMac to let you install extra RAM.

 

2012 is when Apple finally put in USB 3.0. But took out Firewire and the DVD drive. Optional Fusion Drive.

 

2014 first (27") iMac with Retina Screen.

 

2015 can install 64gb RAM in 27". Thunderbolt 2

 

Late 2017 iMac Pro with Xeon processor. Thunderbolt 3.

Finally I solved that issue!

 

Just for the ones who might came to same issue:

 

1) Download MacOS Sierra on different Mac

2) Transfer the installer into older Mac

3) Run installation

     - it get stuck after restart

4) Turn of your Mac

5) Reset PRAM (Cmd-Alt-P-R)

6) Turn on your Mac

     - it should boot into Recovery Mode of MacOS Sierra

7) Double check you are connected to WIFI, even you have connected to WIFI before from MacOS Lion (!!!)

8) Run a new instalation of MacOS Sierra

9) Enjoy :-)

Whatever you've downloaded is most likely an incremental update - the base installers for any OS version are only available at the app store. And, Apple always removes the earlier version of an OS when a new one is introduced. So, since High Sierra has been introduced, that is the only one available.

 

Unless you've downloaded an installer previously - it would be listed under your Purchases - you are out of luck if you do not have an older Mac which cannot install HS.

Hello Tigermidge,

Thank you for using Apple Support Communities. It's my understanding that your iMac becomes unresponsive when trying to install a security update. I can surely see how this could be concerning. I'm happy to help.

I recommend trying to install the update while in safe mode. Starting in safe mode allows your Mac to run certain checks, remove caches, and prevent login items from automatically launching. This can isolate possible third party issues. Use the steps and information in the link below for assistance with safe mode:
Use safe mode to isolate issues with your Mac

Please let us know if the issue persists.

Have a wonderful day!

Do you have a bootable Recovery HD? If so, then try this:

 

Install El Capitan or Later from Scratch

 

     If possible backup your files.

 

  1. Restart the computer. Immediately after the chime hold down the Command and R keys until the Apple logo appears. When the Utility Menu appears:
  2. Select Disk Utility from the Utility Menu and click on Continue button.
  3. When Disk Utility loads select the volume (indented entry, usually Macintosh HD) from the Device list.
  4. Click on the Erase icon in Disk Utility's main window. A panel will drop down.
  5. Set the Format type to Mac OS Extended (Journaled.)
  6. Click on the Apply button, then wait for the Done button to activate and click on it.
  7. Quit Disk Utility and return to the Utility Menu.
  8. Select Install OS X and click on the Continue button.

 

This will install the version of OS X you had installed.

 

Bootable USB Installers for OS X Mavericks, Yosemite, El Capitan, and Sierra

 

First, review this introductory article: Create a bootable installer for macOS. Second, see this How To outline for creating a bootable El Capitan installer. Simply replace the Terminal command with the one from the preceding article by copying it into the Terminal window. You will need an 8GB or larger USB flash drive that has been partitioned and formatted for use with OS X.

 

Drive Partition and Format

 

  1. Open Disk Utility in the Utilities' folder.
  2. After Disk Utility loads select the drive (out-dented entry with the mfg.'s ID and size) from the side list.
  3. Click on the Erase tab in the Disk Utility toolbar. Name the drive, "MyVolume". <---- IMPORTANT!
  4. In the drop down panel set the partition scheme to GUID. Set the Format type to Mac OS Extended (Journaled.)
  5. Click on the Apply button and wait for the Done button to activate. When it does click on it.
  6. Quit Disk Utility.

 

Create Installer

 

Open the Terminal in the Utilities' folder. Choose the appropriate command line (in red) depending upon what OS X installer you want. Paste that entire command line from below at the Terminal's prompt:

 

Command for macOS High Sierra:

sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ High\ Sierra.app

Command for macOS Sierra:

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app

Command for El Capitan:

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app

Command for Yosemite:

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Yosemite.app

Command for Mavericks:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Mavericks.app

 

Press RETURN. You will be asked for your admin password. It will not echo to the Terminal window. Then press RETURN again. Wait for the return of the Terminal prompt signifying the process has completed. It takes quite some time to finish. Be patient.
