About MacMeUp
MacMeUp publishes a set of small, focused macOS utility toolkits, built for people who like to get under the hood of their Mac — installers, EFI partitions, boot managers, and the everyday tweaks that keep a system running the way you want it to.
Why MacMeUp
Every app in the lineup does one job well instead of trying to be a do-everything control panel. That means less Terminal-hunting, fewer configuration files to edit by hand, and a faster path from "I want to do X" to actually doing it.
Each app is free, self-contained, and built natively for macOS — no accounts, no subscriptions, no background services running when you're not using them.
MacMeUp's apps are our collection of the tools we kept reaching for during maintenance and installations, so we cleaned them up and shared them with you.
Boot & installation
For getting macOS onto new hardware, keeping OpenCore/Clover setups healthy, and making sure your Mac always shows you a way to pick a startup disk.
Bootabler
Creates bootable macOS/OpenCore USB installers — or exports a plain ISO/DMG — from Mavericks through the latest release.
— downloads
ISO Image Creator
Converts a full macOS installer app into a standard ISO for VMs, burning, or hand-off to non-Apple tools.
— downloads
Enable Boot Manager
Makes the startup disk picker appear on every boot automatically — no holding the Option key required.
— downloads
EFI & system access
For the tasks that normally mean opening Terminal — mounting hidden partitions and toggling macOS's own security gate.
ESP Mounter
Finds and mounts every EFI System Partition on your disks, and can clone an EFI folder between drives with an automatic backup.
— downloads
Gatekeeper Toggler
Flips Gatekeeper on or off from one switch — handy for testing unsigned or non-notarized builds.
— downloads
Performance & maintenance
For tuning hidden system settings, keeping a Mac running smoothly, and shipping auto-updates for your own apps.
DeskBridge
Seamlessly share your mouse and keyboard across multiple Macs like a software KVM.
— downloads
Mac Tweaks
Surfaces 250+ hidden macOS settings across 18 categories behind simple toggles, sliders, and dropdowns.
— downloads
Mac Optimizer
Bundles the common Mac-tech fixes — NVRAM reset, cache rebuilds, Dock reset — into one panel with an "Execute All" option.
— downloads
Sparkler
Generates and signs the appcast.xml file Sparkle-powered apps need to ship automatic updates — no hand-edited XML.
— downloads
Who it's for
MacMeUp is built for the people who set up other people's Macs, run OpenCore/Hackintosh builds, keep older hardware alive past its official support window, or just like their system configured exactly the way they want it — without digging through forum threads for the right defaults write or other terminal commands every time.
