Today Apple released a new BuildVersion of macOS Mojave, 10.14.4 (18E227). The previous build version was 10.14.4 (18E226). The last time a new BuildVersion was released like this with no documented changes was macOS High Sierra. The BuildVersion went from (17G65) to (17G66).
If you look at 18E226 we do have a size difference.
The size difference between the 2 updates is very small but still different. Opening up both installers in Suspicious Package.app I looked inside InstallESD.dmg. Inside was the Core.pkg. I compared 18E266 to 18E227 and they both have 460,632 files installing 12.63GB to the system.
This is only for the full “Install macOS Mojave.app” installer. This is not an combo update or security update.
You do not have to replace 18E226 with 18E227. If you are preparing for upgrades and already cached 18E226 to your Macs, you dont have to re-cache 18E227. As far as we know this is only a re-write of the original 10.14.4 (18E226) installer. 18E226 is no longer available for download.
BridgeOSUpdate also released
Apple also re-released the BridgeOSUpdateCustomer with the Product ID 041-56509.
The previous BridgeOSUpdate 041-49224 was only a few bytes smaller. As of April 18th 2019 the current T2 BridgeOS/iBridge version is 16.16.4507.0.0,0
