Setting the owner or return-to message on a Mac's lock screen normally means typing blind into a tiny system field and hoping it doesn't wrap badly; LockLines gives you a proper editor that mirrors the real lock-screen field — same cramped width, same non-monospaced font — so you can see exactly how your message will break before you commit it. It's a hyper-specific tool, but useful for anyone labeling shared, lab, or company-issued Macs.
