Hi,In 10.14 last year, Apple stopped installing headers with the command line tools, but it was possible to get them via a separate .pkg installer which they placed at /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg.This appears to be completely missing in 10.15 and I'm unable to compile 3rd party software using the command line tools because of missing headers like zlib and libxml2Anyone know where to get them for macOS 10.15 Catalina?Thanks

I have a script which Xcode runs as a post-action during the archive phase which takes my compiled app, and generates a signed .pkg installer file along with all the other elements of the app.
For the last few years this has worked fine, but for some reason I'm now unable to open the resulting pkg file on macOS 10.10 and 10.11. When I try to open the installer on the older OSes, I'm presented with the following error message:
Installersigned.pkg can't be installed because its digital signature is invalid.
The package may have been corrupted or tampered with. Get a new copy of the package and try again. The signature is_ valid and I can see this in macOS 11 and 10.15 when clicking the certificate icon in the upper corner of the window, so I'm not sure what's going on.
Is anyone aware of any changes to pkgbuild and productbuild which might have caused this? The man pages don't reference anything new that might be relevant, so I'm stuck.
Thanks
