If you are running El Capitan (OS X 10.11), you can download the Boot Camp Support Software by following the steps given below.
- Open the Boot Camp Assistant application.
- Selelct "Action" on the Menu Bar.
- Select "Download Windows Support Software".
Apple officially supports Windows 10 on the newer Macs. Generally these are the 2012 and later models. The originally released version of Windows 10 was number 1511. The Windows version can be determined by opening a Command Prompt window and entering the command
winver. Below is example.
For version 1511, read only access to HFS+ formatted partitions can be enabled by installing the Boot Camp Support Software.
Recently, Microsoft has released a new version numbered 1607. This is referred to as the Windows 10 Anniversary Update. This version has a bug that can prevent read only access to HFS formatted volumes. Here is a link to an Apple Communities web site that also confirms this bug exists. Therefore, if you using version 1601 of Windows 10, you many not be able to access HFS formatted volumes even if you have installed the Boot Camp Support Software. Until this bug is fixed, users will have to use version 1511 or find another way copy data from HFS formatted volumes.
Paragon Software offers drivers that allow read/write access to HFS+ file systems. They offer a 10 day trial period for you test the drivers. I have not done this. So I do not know if the bug also affects their drivers. Another alternative would be to allow OS X to read/write to NTFS formatted volumes. Again, Paragon Software offers this software for OS X.
