This page explains how to **re-download AppleBcUpdate.exe** for your **intel mac** manually.

### 0. (my) Environment
&nbsp;&nbsp; Mac Book Pro 2019
&nbsp;&nbsp; Windows 11(or 10), where Boot camp is already installed.
&nbsp;&nbsp; (Log maybe different depends on environment. BTW, I use Apple Software Update 2.6.3.0 when I wrote this.)

### 1. launch Apple Software Update
&nbsp;&nbsp;(1) Launch "Apple Software Update" from windows start menu.
&nbsp;&nbsp;(2) Help > "Enable logging".
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![1_EnableDebug.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/2147055/adb5c3d9-8f2f-5445-0463-47459b90cd51.png)
&nbsp;&nbsp;(3) File > "Check for Updates...".
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![2_CheckForUpdates.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/2147055/a1024cbc-3c4a-e0b3-c0dd-33f4af8c7991.png)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This action generates Boot Camp update log which you will check from now on.

&nbsp;&nbsp;(4) Tools > "Open Downloaded Updates Folder..".
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![3_openDownloadFolder.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/2147055/05852b83-9465-abd9-ba35-21db66808a8e.png)

&nbsp;&nbsp;(5) Close Apple Software Update.


### 2. on Explorer
&nbsp;&nbsp;(1) go to "Logs" folder under the "Downloaded Updates" folder.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(usually C:\Users\YourName\AppData\Local\Apple\Apple Software Update\Logs.)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![WASU_Log_onExplorer.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/2147055/1366b47a-a457-477f-9721-f12b1a8d9522.png)
&nbsp;&nbsp;(2) open WASU_2872_2022-03-19_10-55-20-0164.log by text editor.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (File name depends on the date/time when you check updates.)

### 3. Find Update Key(ID) from WASU_2872_2022-03-19_10-55-20-0164.log
&nbsp;&nbsp;I would like to have 6.1.15 update, Precision Touchpad driver, for MBP2019.
&nbsp;&nbsp;The followings are the potion where I now focus on.

That is <font color="red">071-01695</font>.

### 4. Download index-windows-1.sucatalog (catalog)

At the beginning of WASU_2872_2022-03-19_10-55-20-0164.log, you can find index-windows-1.sucatalog, which has URL of each AppleBcUpdate.exe(s).
Copy "https://...../index-windows-1.sucatalog" and then paste it onto the address bar of your internet browser, then you will get "index-windows-1.sucatalog" file in your download folder.
Open it by text editor, and then Search <font color="red">"071-01695"</color>

                        <key>URL</key>
                        <string>http://...../downloads/../../071-01695/.../AppleBcUpdate.exe</string>
                    </dict>
                </array>
                        :
                        :
                        :
                </dict>
            </dict>
              :
