I tried reinstall Boot Camp setup for Windows couple times and got the same result.


Please help if anyone has solution for this. Appreciate it and thanks very much

Hi, I have the same missing driver and have constant problems with external devices disconnecting. Particularly external SSDs. I have a 2018 MBPro and the disconnecting drives is causing tons of frustration.

Is this a Windows-only problem? How are these devices connected to the Mac - cables, hubs, etc.?

Do you think this driver is the source of the problem?

It can be. Can you check Windows Event Viewer for error messages for this specific device?

Can we get proper replies from Apple?

  • will the problem be fixed?
  • can I get refund/replacement for a damaged MBP?


I also have the problems listed in the thread. More over, my new MBP is a replacement for my previous one which apparently melted just like some of the posts describe here! The melted MBP has issues with the lid now (it doesn't close fully) and the trackpad has issues with clicking it (I use external mouse and never noticed how the problem developed).

I mainly use Windows/Bootcamp and it seems that due to unfinished drivers I get all these issues (previous mac physically deformed, and the new one has the same missing drivers issues).


We have hundreds of MBPs in our office, not sure how many have these problems, but can we get proper reply from apple directly for these problems?


Thanks

I suggest you contact Apple Technical Support. If you have bought Macs from a reseller, you should raise this through the reseller as well. If you have a Corporate Business relationship with Apple, you should pursue under the auspices of that relationship.

Then the BC Assistant on such models should have been removed with a clear notification. It is a bad idea to have statements like If you see the alert 'Installation cannot proceed with Boot Camp configured' - Apple Support (as referenced in the Mojave-compatible link - Install Windows on your Mac with Boot Camp - Apple Support ) and release products which behave incorrectly.

This is incorrect. See when are boot camp drivers going to be updated ? and the iMac Pro (Mac computers that have the Apple T2 chip - Apple Support) already works correctly.


The T2 has many issues. Also, 'immature' products should clearly warn the consumer about limitations. 😉 (... but there is always a way out as stated in Apple - Legal - Licensed Application End User License Agreement ).


This is not pointing the finger at you, but the sources of information that you are working with.

Apart from hardware-related issues, there are issues like Keyboard and touchpad after restart from windows to macOS not working which directly point to T2. From my perspective T2 is a single-point-of-failure. To save real-estate on boards, more such SPoF are created.


I prefer waiting another 12-24 months for maturity in the T2 controller design, before I invest in products with it.

It is a known issue, Usualy apple sets it to be under Hidden devices. It controls the battery power usage and this is why bootcamp has such horrible battery life. Also it controls the CPU this is also why bootcamp thermal throttles. I have contacted apple for nearly 3 months at the SR EXEC LEVEL. They state their engineers are working on it and that bootcamp is NOT ready for the 2018 macbooks.

No, as of current bootcamp is just not ready or designed for 2018 macbooks. If you check your drivers including Sound Card you will notice microsoft generic drivers in use, check driver info. There is currently no Road Map for a Bootcamp Release for the 2018. Apple recommends using Vmware and Parallels. Apple also will not have a fix for the rebooting issue, where you must shut down windows then power the machine back on to enter MacOS with keyboard and mouse support. They stated it compromises the T2's Security. In english it is what is it.
