Requires at least macOS 10.12 or higher.
For older Macs use the Mac OS i386 version.

You need to download and install all three packages fpc, fpc-src and LazarusIDE.

fpc - the Compiler, some command line tools, base units and non visual components like database access
fpc-src - the sources of fpc and its packages, needed for code browsing
LazarusIDE - the IDE, visual components and help files

"Unknown developer" error when installing (Mac OS X 10.7 Mountain Lion and later)

If you get the message that the FPC installer was created by an unknown developer and cannot be opened, right-click on the installation package and choose "Open" in the contextual menu. If this does not work, you may first have to go to System Preferences -> Security & Privacy -> General, and "Allow apps downloaded from: Mac App Store and Identified developers". These workarounds are required because we do not pay Apple 79 euro per year, which would prove you can trust us.

Xcode 5+ compatibility (OS X 10.9 Mavericks; for OS X 10.8 Mountain Lion, see below)

FPC 3.2.0 is qualified for use with Mac OS X 10.4 till macOS 10.15. Xcode 5 and later however no longer install the command line tools by default, which are required by FPC. To install them manually, open "/Applications/Utilities/Terminal", execute "xcode-select --install" and choose "Install". Afterwards, FPC will function correctly.
