adb fails to start daemon on macOS Catalina+ Solution: Revision 28.0.1 is 32-bit on macOS. As of Catalina, 32-bit support is removed. Use a virtual machine or an older macOS version (Mojave or earlier) for this revision. Conclusion Installing Android SDK Platform-Tools revision 28.0.1 is a straightforward but deliberate process. While modern developers would typically use the latest revision, specific use cases—such as supporting Android 8.x/9.x devices without partition scheme changes, maintaining legacy automated testing scripts, or avoiding newer adb security restrictions—justify the need for this older version. By carefully obtaining the correct archive, configuring the system path, and addressing platform-specific driver or authorization issues, developers can ensure a stable, reproducible environment for Android debugging and flashing tasks long after this revision’s original release date. Note: As of 2025, Google no longer distributes revision-specific Platform-Tools via the primary SDK Manager. Archival downloads should be validated against official SHA-256 checksums to prevent security risks. install android sdk platform-tools -revision 28.0.1-

Install the Google USB Driver (revision 12 or higher) via the deprecated SDK Manager or download the standalone driver package. For OEM devices (Samsung, Xiaomi, etc.), install the manufacturer’s specific drivers before connecting the device.
