Apple’s current user-facing Rosetta guidance says Intel-only applications remain supported through macOS 27, while macOS 28 limits Rosetta to certain older unmaintained games. That makes this a practical housekeeping issue for the BigMac and MiniMac, especially if a small utility, plug-in or legacy installer quietly relies on Intel translation.
You can check an application in Finder by selecting it and choosing Get Info. The Kind field distinguishes Application (Intel), Application (Universal) and Application (Apple silicon). On macOS 27, Apple also documents an Intel-based Apps list in System Settings → General → About.
No reason to replace working software immediately, but it is worth identifying the few Intel-only pieces that might interrupt a long-running automation or Stream Deck workflow after a future OS upgrade. Prioritize replacements with native Apple-silicon builds.
