It's Xcode driven.
If the latest Xcode cannot be installed on Mojave, cross-compiling might not be possible...
...OR manually copying build tools might do the trick.

I have macOS 11.0 installed on an external SSD and by pointing FPC to its Xcode folders with the -XR/-FD parameters, I can indeed successfully cross-compile to Darwin/AArch64 from 10.14.

trev,

According Release Notes (https://developer.apple.com/documentation/xcode-release-notes/xcode-12_2-release-notes) for Xcode 12.2

Quote

Xcode 12.2 requires a Mac with Apple silicon running macOS Big Sur 11 or later, or an Intel-based Mac running macOS Catalina 10.15.4 or later.

So officially it's not supported for Mojave.

I cross-compile for aarch64 and x86_64 on Macbook 12 (Intel) with Big Sur. Lazarus 2.0.10 + FPC 3.2.1 fixes.

Excellent, thanks Jonas. I also happen to have Big Sur on an external SSD :)
