High Sierra 10.13.3 Update error

I have a new iMac Pro and have installed a macOS update already. With the latest 10.13.3, I get the error as it is calculating the time too download: (602) and it appears that the download isn't taking place. I have a wired network connection and I have also tried wirelessly. No go. Any ideas?


BTW, on the same router, the download works fine on a MacBook!

iMac Pro, macOS High Sierra (10.13.3), null

Yeehahhhhhhh!


I think I found a way around this. There is a special Apple page where you can download the update directly:

https://support.apple.com/kb/DL1952?locale=en_US


It worked!


Looking at 602 errors in Apple knowledge bases, it may be due to 32-bit apps and I am wondering if my external Western Digital disk subsystem apps (I have their USB-C drives for Time Machine backups) or AVG anti virus is causing issues?

It seems my problem is solved.. I've got a SSD drive which has revision MU01 installed. I've got the feeling that this revision doesn't work well with 10.13 at all.. So i've decided to upgrade it to MU02. After that i've reinstalled a full previous version of IOS and did an update to 10.13.3. This time it went ok.. Maybe some-one who has similar problems and uses a SSD drive can use this.. Regards, William
