Maccy and Bluetooth Keyboard Switching: What Actually Fixes It

Last updated: November 5, 2026 · About 7 minutes to read

Quick answer

Maccy doesn’t track which keyboard you’re using, so switching Bluetooth keyboards can’t directly “break” it. When the shortcut or paste stops working after a switch, the cause is almost always a changed modifier mapping, a different keyboard layout, or a shortcut macOS no longer delivers. Check those three, in that order.

Let’s get the myth out of the way: there is no “Bluetooth bug” in Maccy app. The app has no idea whether keystrokes arrive over Bluetooth, USB, or the built-in keyboard. It asks macOS to watch for one global shortcut and, optionally, to paste for you. Everything that changes when you swap keyboards happens one layer below Maccy mac.

That’s good news, because those layers are well understood. Below is a triage table, then each fix in detail.

Which symptom do you have?

Symptom after switching keyboards	Most likely cause	Go to
The Maccy shortcut does nothing on the new keyboard, but works on the old one	Modifier keys are mapped differently (Alt/Win vs Option/Command)	Fix 1
Maccy opens, you pick an item, but nothing pastes	Missing Accessibility permission, or a layout that changes behavior when Command is held	Fix 2 and Fix 4
Typing Option+P in Maccy’s search box types a “π” instead of pinning	Option is producing a character, not acting as a shortcut modifier	Fix 3
Shortcut stopped working everywhere after a macOS upgrade, not just on one keyboard	Option-only global shortcuts are no longer delivered on macOS Sequoia and later	Fix 3
Maccy opens but arrow keys or search typing feel dead	Focus problem in Maccy’s window; often cleared by restarting the app	Fix 4
Clipboard history is “missing” after moving the keyboard to another Mac	History is stored per Mac, not per keyboard	Multi-Mac note

Fix 1: Check modifier keys for the specific keyboard

macOS stores modifier-key remapping per keyboard, not globally. That’s the single most common reason a shortcut works on your Magic Keyboard and fails on a Bluetooth keyboard from another maker.

Many third-party keyboards are built for Windows first. Their bottom row reads Ctrl, Win, Alt instead of Control, Option, Command. Some macOS-aware models include a switch for this; many don’t. If the keyboard is sending Windows-style modifiers, the physical key you think of as Command may be arriving as Option, and Maccy clipboard‘s default shortcut (Shift+Command+C) never fires.

Connect the keyboard you’re troubleshooting.
Open System Settings → Keyboard → Keyboard Shortcuts… → Modifier Keys.
Use the keyboard selector at the top of that pane to choose the Bluetooth keyboard by name.
Make sure Command, Option, and Control each map to themselves, or swap Option and Command if the physical layout is Windows-style and you want the Mac positions.
Repeat for each keyboard you switch between. The settings don’t carry over.

If the keyboard has a Mac/Windows mode switch (common on multi-device models), set it to Mac mode first and test before touching any software mapping.

Fix 2: Watch for layout quirks, especially with Command held

Maccy pastes by sending Command+V to the frontmost app. That relies on macOS interpreting the “V” correctly. People using Dvorak, Colemak, or custom layouts have reported in Maccy’s GitHub issue tracker that pasting failed because the layout sent a different key when Command was held. In one reported case, the workaround was adding “⌘” to the layout’s name so macOS treated it as a command-aware layout.

Why does this matter when switching keyboards? Because many people pair a hardware layout change with a software one: a different keyboard in a different language, a different input source selected in the menu bar. Check which input source is active (the flag or icon in the menu bar) after the switch.

A fast diagnostic: copy something, then press Command+V yourself in a text field. If that works but Maccy’s automatic paste doesn’t, the problem is between Maccy and the keystroke it sends. Move on to Fix 4.

Fix 3: Stop using Option-only shortcuts

This one catches people who think they have a keyboard problem and actually have a macOS problem. Starting with macOS Sequoia (15), Apple no longer allows global shortcuts whose only modifiers are Option or Shift+Option. Maccy was among the apps affected, and the recommended workaround is to include Command or Control in the combination. heise covered the change, and Maccy’s issue tracker has a thread on Option-key shortcuts failing since Sequoia.

It looks like a keyboard issue when you happen to switch keyboards the same week you upgrade macOS, so the symptoms coincide.

Open Maccy’s settings (click the menu bar icon, then Settings).
Find the shortcut recorder for opening Maccy.
Clear it and record a new combination that includes Command or Control, for example Shift+Command+C (the default) or Control+Option+C.

There’s a related quirk inside Maccy’s window. Its in-window actions, like pinning an item with Option+P, are keystrokes that compete with typing into the search field. A maintainer has noted that Option+P can type “π” into search on some setups, and that picking a different pin shortcut (Control+Shift+P was the example) avoids it. If your new keyboard handles Option differently, you can run into this on one keyboard and not the other.

Fix 4: Reset permissions and restart Maccy

If modifiers and shortcuts check out, reset the plumbing:

Open System Settings → Privacy & Security → Accessibility.
Find Maccy. Toggle it off, then on. If it’s missing, add it with the + button. Maccy needs this permission to paste for you.
Quit Maccy fully (menu bar icon → Quit) and reopen it.

The restart step is not superstition. Several users in Maccy’s issue tracker have described focus problems, such as the search field not receiving typing or arrow keys not moving through the list, that went away after quitting and relaunching the app. The cause varied by report, and some issues were later fixed in newer releases, so make sure you’re on the latest version.

A note for Easy-Switch and multi-Mac keyboards

If your keyboard pairs with two or three Macs and you flip between them with a button, remember what moves and what doesn’t. Your keystrokes follow the keyboard. Your clipboard history does not. Maccy is local-first, so each Mac keeps its own history, and nothing syncs through the keyboard or through Maccy.

If you rely on Apple’s Universal Clipboard to move individual items between Macs, treat that as a separate Apple feature.

Also confirm Maccy is installed and running on every Mac you switch to. It sounds obvious, but “Maccy doesn’t work on my second Mac” is sometimes just “Maccy isn’t running on my second Mac.”

Five-minute test routine

Switch to the Bluetooth keyboard and press Command+C then Command+V in any text field. If this fails, it’s a macOS or keyboard problem, not Maccy (Fix 1).
Press Maccy’s shortcut. If the window doesn’t appear, check the shortcut and modifiers (Fix 1, Fix 3).
Pick an item with Return. If it doesn’t paste, toggle Accessibility permission (Fix 4).
Type in Maccy’s search field. If typing is dead, restart Maccy (Fix 4).
Still stuck? Test the same steps on the built-in keyboard. If everything works there, the keyboard’s mapping or mode is the culprit.

When to report it as a bug

If you’ve worked through all four fixes and the problem is reproducible on one specific keyboard, it’s worth an issue on Maccy’s GitHub repository. Include the Maccy version (from the About window), your macOS version, the keyboard make and model, the active input source, and whether the built-in keyboard behaves differently. Without that, nobody can reproduce it. With it, a real fix becomes possible.

Frequently asked questions

Why did Maccy stop working after I switched Bluetooth keyboards?

Maccy doesn’t track which keyboard is connected. The usual causes are a different modifier-key mapping on the new keyboard, a different keyboard layout, or a shortcut macOS no longer delivers, such as an Option-only global shortcut on macOS Sequoia and later.

Why does Maccy’s hotkey work on one keyboard but not another?

macOS stores modifier-key mappings per keyboard. A Windows-style Bluetooth keyboard can send Alt and Windows keys where a Mac keyboard sends Option and Command, so the same physical keys produce a different shortcut.

Why does Maccy select an item but not paste it?

Automatic pasting needs Accessibility permission, and it sends a Command+V keystroke. Missing permission or an unusual layout can stop that keystroke from landing. Copying the item and pressing Command+V yourself is a quick diagnostic.

Does Maccy sync clipboard history between Macs when I switch a keyboard between them?

No. Maccy is local-first and keeps its history on each Mac. Switching a multi-device keyboard to another Mac switches the keystrokes, not the clipboard history.

Which Maccy shortcut should I use if Option-based shortcuts fail?

Use a combination that includes Command or Control, such as Shift+Command+C (Maccy’s default) or Control+Option plus a letter, rather than Option or Shift+Option alone.

The short version

When Maccy seems to misbehave after a keyboard switch, it’s almost never Bluetooth and almost never Maccy itself. Check modifier mapping per keyboard, check the active layout, move off Option-only shortcuts, and reset Accessibility permission. That sequence resolves the large majority of these reports, and if it doesn’t, you’ll have the details needed for a useful bug report.

If you haven’t tried Maccy yet, it’s free, open source, and keeps your history on your own Mac. And a question for you: which keyboard are you switching between, and does it have a Mac/Windows mode switch? That detail often settles the whole thing.

If you want to try it yourself, maccy.at is a free, open-source clipboard manager for macOS — the clipboard history guide covers the rest.
