 Alternatively, you can skip the macOS build by adding `--os=lw` below.

 Gitian building Mac OS SDK
 ==========================
 
-On the host machine, register for a free Apple [developer account](https://developer.apple.com/register/), then download the SDK [here](https://developer.apple.com/devcenter/download.action?path=/Developer_Tools/Xcode_7.3.1/Xcode_7.3.1.dmg).
+On the host machine, register for a free Apple [developer account](https://developer.apple.com/register/), then download the SDK [here](https://download.developer.apple.com/Developer_Tools/Xcode_10.2.1/Xcode_10.2.1.xip).
 
-MacOS host
-----------
-
-Using Mac OS X, you can mount the dmg, and then extract the SDK with:
-```
-  $ hdiutil attach Xcode_7.3.1.dmg
-  $ tar -C /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/ -czf MacOSX10.11.sdk.tar.gz MacOSX10.11.sdk
-```
-
-Clean up the files you don't need:
-
-```sh
-diskutil unmount /Volumes/Xcode
-rm Xcode_7.3.1.dmg
-```
-
-Non-MacOS host:
+Extract the SDK
 ---------------
 
-Alternatively, you can use 7zip and SleuthKit to extract the files one by one.
-The script [extract-osx-sdk.sh](https://github.com/Bitcoin-ABC/bitcoin-abc/blob/master/contrib/macdeploy/extract-osx-sdk.sh) automates this. First ensure
-the dmg file is in the current directory, and then run the script.
-
-You may wish to delete the intermediate 5.hfs file and MacOSX10.11.sdk (the directory) when
-you've confirmed the extraction succeeded.
-
-```bash
-apt-get install p7zip-full sleuthkit
-contrib/macdeploy/extract-osx-sdk.sh
-rm -rf 5.hfs MacOSX10.11.sdk
-```
+Follow [these instructions](../../contrib/macdeploy/README.md#SDK-Extraction) to extract the SDK archive from the download.
 
 Copy SDK to Gitian VM:
 ----------------------
 Copy it to the Gitian VM and clean up, e.g.:
 
 ```bash
-scp MacOSX10.11.sdk.tar.gz gitian:
-rm MacOSX10.11.sdk.tar.gz
+scp MacOSX10.14.sdk.tar.gz gitian:
+rm MacOSX10.14.sdk.tar.gz
 ```
 
 Login to the VM and:
 
 ```bash
 mkdir -p gitian-builder/inputs
-mv MacOSX10.11.sdk.tar.gz gitian-builder/inputs
+mv MacOSX10.14.sdk.tar.gz gitian-builder/inputs
 ```
