After fixing, run sudo thermal levels to verify your Mac’s temperature is back under 60°C at idle. Then, go create something amazing. Have a unique variation of error 2512? Mention "groupdmg SEGV" or "mount_hfs: Operation not permitted" in the comments below.
Adobe recently released a silent update for the Creative Cloud installer (version 5.8.2 and above) that works around Monterey’s restrictions. But if you are stuck with an older installer:
But as we have shown, the problem is purely mechanical: a legacy mounting process (groupdmg) fighting modern macOS security (Monterey) and losing, then burning CPU cycles in a rage loop (hot).
