My StarTech sv215micusba KVM requires that I use Scroll Lock, Scroll Lock, Enter, but my Apple keyboard doesn't have a Scroll Lock key. I found this reference:


But it refers to key combinations used for Windows functionality (driver-dependent). What combo would I need to press in order to send the correct sequence to my KVM switch?

  • Would it be worth naming the exact KVM in case anyone has any specific experience, e.g. modifying the key combination?

Having had a look at the StarTech SV215MICUSBA manual (PDF), on page 7 it says:

To initialize Mac keyboard mapping, please execute the following hotkey sequence:

[scroll],[scroll], [F2], [Enter]
[ctrl] [ctrl] [F2] [Enter]

Once this has been done, the following keyboard mapping will apply:

Then in the table below, it indicates that the Scroll Lock Lock key on a PC keyboard is mapped to F14 on a Mac keyboard.

Assuming you have a full Apple keyboard, its probably worth trying this out.


Some KVM switches have alternate methods of switching besides Scroll Lock. I would read the manual to see if there is any similar feature on your KVM.

Otherwise, you might need to resort to having an additional PC keyboard hooked up to the KVM switch with the sole purpose of sending the Scroll Lock command.


If you have a large Apple keyboard with an F14 Key, Shift-F14 has been documented to work as a Scroll Lock key in Excel. I don't have any documentation about your sv215micusba device, but if you have a large Apple keyboard, that key combination might work.


Use the free remap tool for macbook available at https://pqrs.org/macosx/keyremap4macbook/index.html.en, enable functions keys in the settings of the keyboard, and remap the key you want to F14.

Example for F6 to F14: add the following xml in your private.xml file inside ~/Library/Application Support/KeyRemap4MacBook/:

<?xml version="1.0"?>
    <name>Swap F6 to PrintScroll</name>

None of the above solutions were working for me, and I was unable to remap my KVM's (Syba SY-KVM31034) hotkey, so I wrote this simple tool that sends the necessary double scroll lock signal to my KVM. It can even be assigned to a key combo: https://github.com/benjaminstout/osx-kvm
