Windows 1903 update

[UnMix]

Is the feature update safe to upgrade to now? It hasn't let me upgrade to it for a while- until now. Just want to check beforehand for issues to be on the safe side and see if anyone else has installed it.

I have it running on my 5,1 MacPro since May with no issues whatsoever.

Wasn't there a problem if you still have the older 5.1 bootcamp software on the machine? 6.1 works fine for me with 1903.

I did the update of the bootcamp tools before I upgraded to 1903, so I can't say...

I just looked into this myself. Just moved from 1803 to 1809, as Microsoft’s track record for these upgrades isn’t great.

Performed an upgrade to 1903 on a test system and hit a BSOD on login; WDF Violation.

If you have an older version of the BootCamp drivers installed that supported Windows 7 (I’m using a MacPro5,1), then the root cause is apparently MacHALDriver.sys located in C:/Windows/system32/drivers.

This file needs to be moved or renamed for 1903 to run properly, but the side effect is the BootCamp software will stop running, killing your use of the function keys (I have an ACD, so this is important), as well as being able to tell the system to reboot into macOS conveniently.

If you go here, this chap has developed software to speak to the ACD if you’re just using a PC, so this should be a workaround.

Just to add, I did wonder whether obtaining a more recent version of the BootCamp WindowsSupport package might contain a newer version of MacHALDriver.sys that supports 1903, and sure enough it does.

If you have another newer Mac to hand, you can download the WindowsSupport folder by launching Boot Camp Assistant, clicking View and Download Windows Support Software. This contains a newer MacHALDriver.sys, as well as an ini and inf with the same name, which I copied over too for fun.

If you run into this issue and don’t have a more modern Mac to hand, will happily post this file for others to use.

I upgraded to Windows 10 version 1903 on my 2014 MacBook Pro 15” when it was first released, with no problems noticed so far.

I didn't have problems with upgrade too.
