Hi, Part of the the 4.16 release has scripts in the ide directory (addAIRtoSDK.sh, setFlashPlayerVersion.sh) that you could run on an older version of the SDK to get AIR 24 on OSX like so: ./addAIRtoSDK.sh 24.0 <path to FlexSDK>
You should be able to also copy the installer.xml for the 4.16 release (or release branch) into an older SDK and run this (but I’ve not tested 100% that this works): ant -f installer.xml -Ddo.air.install=true air-download -Dair.sdk.url.server=https://airdownload.adobe.com -Dair.sdk.url.folder=air/mac/download/24.0 -Dair.sdk.url.file=AdobeAIRSDK.dmg It also possible to manually overlay AIR in the SDK it but some manual editing of configuration files is required. Thanks, Justin
