That’s an interesting angle — and you're right to notice something unique.

A Word of Caution

• Security: Mavericks (10.9.5) is end-of-life. It no longer receives security patches. Do not use it as a daily driver on a machine connected to the internet unless isolated.
• Certificates: Due to expired SSL certificates, you will likely need to adjust the system date back to 2013-2015 to successfully install certain apps or access the internet after a fresh DMG install.
• No 32-Bit App Support Loss (Yet): Unlike modern macOS (10.15+), Mavericks fully supports 32-bit applications. This is actually its primary modern use case.
