means A waterproof raincoat — and also the trademarked name of Apple's personal computer line.

from The raincoat comes from Charles Macintosh, a Scottish chemist who in the 1820s patented a way to bond rubber between layers of fabric, making cloth waterproof; his surname became the garment's name, later casually spelled 'mackintosh' or clipped to 'mac.' Apple's Macintosh computer, launched in 1984, took its name from the McIntosh apple (a favorite of the engineer who championed the project) but altered the spelling to avoid a trademark clash with the audio equipment maker McIntosh Laboratory — so the coat and the computer share a name by pure coincidence, not lineage.
