Installing Rein (Mac)

Open the downloaded Rein.dmg and drag Rein into Applications. Rein is notarized by Apple, so it opens normally. On first use Rein asks to install a small helper — that’s what makes fan, battery and clamshell control possible, and you approve it once.

Prefer Homebrew? brew install --cask lukedavid2/rein/rein installs the same signed, notarised build. Rein still updates itself.

Rein Remote (iPhone) quick answers

Pairing: Mac → Rein → Remote → Show pairing code → scan the QR with the phone.
“Reconnecting…” forever: the Mac is asleep or offline. It reconnects automatically once the Mac is awake.
Drag / select text: press-and-hold the trackpad (you’ll feel a tick), then drag — or hold the Left click button and drag with another finger.
Forget this Mac: the ••• menu, or from the reconnect screen.

Rein for Mac quick answers

Your licence code: after paying on Ko-fi, open the claim page and enter the email you paid with. It is usually ready within a minute, and you can come back to the same page for it any time. Then Rein → Settings → License → paste → Unlock. Not there after ten minutes? Email with your Ko-fi receipt.
Refunds: within 14 days of buying, no questions asked. Email from the address you paid with (or include your Ko-fi receipt) and you get a full refund to the way you paid. The details are in the terms.
Removing Rein completely: remove the helper, turn off the audio driver, then delete the app and two files. The trust page has the steps and the file paths.
Everything back to normal: hit Reset to Auto — or just quit. Rein’s rule is that the worst case is always plain macOS default behaviour, even after a crash.
Casting: 4K MKV casting works out of the box — the media engine is bundled inside the app.
Versions: the phone shows its version under the Mac’s name; the Mac app shows its own in Settings.

Requirements

Rein: Apple Silicon Mac, macOS 14 or later. Rein Remote: iOS 17 or later.
