Avid does not officially support this configuration. Pro Tools 10’s last officially supported OS was Mountain Lion (10.8.5). However, with workarounds, it can run on High Sierra, though not perfectly. This guide is for legacy users who need old RTAS/32-bit plugins or TDM hardware.

Open the OSInstall.mpkg on your desktop using (a popular shareware tool for modifying installers) or modify the distribution script to ignore the version check.

If you try to run the standard installer, it will block you with compatibility warnings.

Terminal: sudo spctl --master-disable

It runs , but it’s not stable for critical paid sessions. Occasional random quits and graphic glitches (especially with large sessions). Fine for recalling old projects or light tracking. For daily work, stay on Sierra (10.12.6) or use PT 12/202x.
