Apple’s Macs have been a popular development platform for many years now, but IBM have never really committed to supporting DB2 servers on macOS it seems. There was a version of DB2 Express-c v9.7 made available some years ago, but it was lacking features and is obviously way too far out of date to consider these days. A useful solution was to run Docker containers, or full virtual machines with Linux or Windows to make DB2 available locally, but the switch to the new Apple Silicon processors, or the M1 chip, means the Mac now uses the ARM64 instruction set rather than sharing the Intel/AMD x86-64 processors common to Windows and Linux platforms – and there is no option to download a copy of DB2 that runs on this processor.
So is that the end of having DB2 installed locally? Not quite.
