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?
Hi, I have an IMac running 10.12.5 with base installation but additional Java versions and also a MacBook Pro running 10.12.4 , also basic installation and additional Java versions. Both have external USB drives for TimeMachine.
I did a full backup to Time Machine before installing 10.13.3.
The installation on IMac was to download from App Store and then install as separate activities, worked almost perfectly, only issue being that it lost my email account passwords.
The installation on MacBook Pro did the download and install as one operation, again perfect.
A point to note is that I did not include signing into ICloud during the installation as in the past I found this hammers the internet data usage.
I'll hold off before I do the last update. Im curious as to what configuration iMac Pro both of you have. And if someone post having success with update, please include what configuration iMac pro?
Also, Mark, did you actually try it or this post is worrying you to see what the resolution is?
Just pulled a new iMac Pro out of the box, plugged in two 4k LG UltraFines, a Samsung SSD T5, and clicked Update ... 10.13.3 installed without issue.
I just did the update and had no issue.
That is great, Mark! I'm still stuck ...
BTW, I sent in a support request to Western Digital. 🙂
I also don't agree that hardware is the issue. Just a week or so ago, High Sierra 10.13.2 installed no issue. I cleaned out spare files and rebooted. No dice. Perhaps there is a login startup apps that should be removed but on a similar community note, the suggestion was to install using safe mode (hold Shift while booting). I will try that tonight.
The 602 issue that I have is at the very beginning when the download time is being calculated. Is that the same for you? In fact, it doesn't even try to download. So, I can't imagine that Apple's download mechanism performs some sort of hardware check.
I updated a MacBook Retina 12 AND a MacBook Pro 13 with 10.13.3 and both worked. So, I am wondering if the speed of the iMac Pro's processor and the time-to-download calculation has a problem?
Removed WD software (all traces in Libraries) and a bunch of other stuff as as well. Still getting 602 error from App Store update and downloaded dmg update file. Really frustrating.
