Unable to Install on MacOS Catalina?

This article concerns an older macOS Catalina installation. First distinguish an operating-system compatibility problem from a macOS security prompt.

Check compatibility first

Confirm that the exact Profiler installer supports your macOS version and processor. Use GiesenCloud Downloads and the system-requirements article. A security setting cannot make an incompatible release run on Catalina.

If macOS blocks opening the app

Download Profiler only from the official GiesenCloud download channel. For a normal first-launch prompt, check the source and developer before approving the app.

If the developer cannot be verified, the app is reported as damaged, or macOS reports malware, contact Giesen Support with the exact message and installer version. Follow Apple’s guidance for opening apps safely; do not disable Gatekeeper or apply a blanket security bypass.

Security controls and their locations differ between Catalina and current macOS. Changing the general “App Store and identified developers” preference is not a guaranteed solution to every installation error.

Information to send to Support

Include your macOS version, Intel or Apple Silicon processor, Profiler version, download source and the exact error text. This allows Support to distinguish compatibility, download and signing issues.
