LOGO!Soft Comfort V8.2.1 is not listed as supported on macOS 10.15 Catalina. Catalina also cannot execute 32-bit applications, while the available evidence indicates that this LOGO!Soft Comfort release still contains 32-bit code. Treat failure to launch as an operating-system compatibility issue rather than a LOGO! project-file fault.
Confirm the compatibility boundary
The V8.2.1 operating-system list ends at Mac OS X 10.11 El Capitan. Reports that the application ran through macOS 10.14.6 Mojave do not make those later releases tested or supported by Siemens.
| Environment | Evidence status | Engineering decision |
|---|---|---|
| Mac OS X 10.7 through 10.11 | Listed for V8.2.1 | Use a listed release when vendor support is required. |
| macOS 10.14.6 Mojave | Reported to run, but not listed | Treat operation as unverified and unsupported. |
| macOS 10.15 Catalina | Not listed; 32-bit applications cannot run | Do not expect V8.2.1 to launch directly. |
Diagnose a Catalina launch failure
First confirm that the Mac is running 10.15.x and that the installed engineering package is LOGO!Soft Comfort V8.2.1. If the same installation worked before the Catalina upgrade but no longer opens afterward, the evidence supports a 32-bit compatibility boundary. Reinstalling the same release does not change that architecture constraint.
Select a temporary operating environment
- For an existing Mac that has not been upgraded, retain macOS 10.14 only as a temporary operational measure and recognize that this release is outside the stated V8.2.1 support list.
- For a Mac already running Catalina, consider a virtual machine with Linux and install the Linux edition of LOGO!Soft Comfort. The evidence mentions Linux Mint and VirtualBox as one proposed combination, but does not establish that combination as Siemens-supported.
- Verify that the application launches inside the selected environment and that the required LOGO! project can be opened before relying on it for service work.
The evidence provides no confirmed Catalina-compatible release or release date. Submit a request through an official Siemens support channel when a supported macOS 10.15 solution or schedule is required.
FAQ
Does LOGO!Soft Comfort V8.2.1 work on macOS Catalina?
macOS 10.15 Catalina is not in the V8.2.1 support list, and Catalina cannot run the 32-bit code identified in this release. Direct launch should therefore not be expected.
What is the newest supported Mac OS for LOGO!Soft Comfort V8.2.1?
The stated list ends at Mac OS X 10.11 El Capitan. Operation reported on macOS 10.14.6 Mojave remains outside that list.
How can I run LOGO!Soft Comfort after upgrading to Catalina?
Use a separate compatible environment; the evidence proposes running the Linux edition in a Linux virtual machine. Verify application launch and project access, because no specific virtual-machine configuration is confirmed as supported.
