My High Sierra is at version 10.13.3, and I got the 10.13.6 update waiting for me to download and install. I did download and install it, restarted; but I still get the 10.13.6 update waiting for my installation. Having repeating the update several times with no avail. I do not have any anti-virus software installed.
Any solution? Thanks

If you still have the Combo Update on the drive, shut down computer. From Cold boot, hold SHIFT KEY and then power button - this is Safe Mode. Keep hold Shift key until it boots up. It will take longer the boot. You will know you are in Safe Mode because in Top Right corner of screen a RED message will appear saying in Safe Mode. Now run the Combo Updater again

If you are trying to update via the App Store, try this instead, Download macOS High Sierra 10.13.6 Combo Update
once downloaded double-click to install.
I successfully updated it by:
1. Create a bootable usb flash drive (8GB) containing 10.13.5 mac os which I downloaded a few weeks back (you may choose to download the latest version .6, but I chose not due to long downloading time)
2. Shut down and reboot by pressing Option key, choose your flash drive, then install it without erasing your main ssd drive.
After finishing the installation, reboot, all my apps and settings are still intact. I then opened App Store to further update it from .5 to .6 without problem (no flash drive needed).
Thanks for all your assistance.
BEFORE doing this, make sure you have a very recent Time Machine Backup AND if possible a Clone using Superduper or Carbon Copy Cloner ( 30 day free trial ). Each should be to separate external HDs.
Now read the Apple Support link provided How to reinstall macOS - Apple Support using the Option, Command and r option.
Hi,
Thanks. I did try that too. The installation progressed well till it restarted again; but after login, there is a message saying that some software can't be installed and I'm still at 10.13.3. Not sure how to proceed.
Thanks. Installing the update in Safe mode also did not success. It went through the restart and updating till restart again. Then the same pop up message display ....some app cannot be updated.
I've had the same problem and have tried the command R thing numerous times. Still no success.
