Cannot install 10.12.6 on iMac (27

As the title stated... I cannot install 10.12.6 on my iMac (27-inch, Late 2009) with 10.12.3 already installed. I download the update but it will not install AND it does not say that my computer is incompatible.

Thanks

Try downloading the combo updater and see if it will run.

Download macOS Sierra 10.12.6 Combo Update

Just to be clear under “About this Mac” it shows you are running 10.12.3.

You may want to try installing it in Safe Mode. Something you have installed may be interfering.

macOS Sierra: Start up in safe mode
