Adding Wi-Fi and Bluetooth to hackintosh to enable Apple-specific features

When I started with my hackintosh I did not have Wi-Fi or Bluetooth support in it. I used Ethernet to connect to my home network and it worked fine, I had no need for Wi-Fi.

Later I wanted to use more “Apple-specific” features, so I started looking for how to make them work with my hackintosh.

Bluetooth

Adding Bluetooth support to a hackintosh is quite easy, you just need to buy any of these USB adapters:

All of them are natively supported in macOS, no extra drivers are needed.

GMYLE Bluetooth 4.0 Adapter

I bought the GMYLE Bluetooth 4.0 Adapter, found it on German Amazon.

Thanks to adding Bluetooth support I got:

  • Ability to use Bluetooth keyboards, speakers, headphones
  • SMS messages showing on macOS
  • incoming phone calls showing on macOS

The SMS relying feature was really nice, especially when needing to copy security codes sent by SMS by services that do not support 2FA via TOTP.

Justa s a side note, iMessage worked right from the start, Bluetooth is not needed for it.

Wi-Fi

Wi-Fi required for some Apple-specific features

The one thing that I was missing was AirDrop. I started taking screenshots regularly on my iPhone during development and testing and there was no easy way to move them to the hackintosh without AirDrop.

To make AirDrop and additional features like Handoff work you need not only Bluetooth but also an internal Wi-Fi card.

Editing macOS app About dialog

When you create a macOS app and keep the default menu, you automatically get an About dialog. This dialog shows basic info about the app.

If you want to add more information to this dialog there is no obvious way to do it. You need to start reading the Apple documentation to finally discover that it is actually quite simple.

Detecting click on a specific NSTableViewCell

When you use NSTableView in an macOS application, there is no direct way to know a specific NSTableViewCell was clicked by the user. In my Localization Editor project I wanted the user to be able to focus a NSTextField when clicking anywhere in the NSTableViewCell it is contained in, so I had to implement it myself.

I created a new delegate extending the NSTableViewDelegate with one additional method informing about a NSTableViewCell getting clicked

protocol NSTableViewClickableDelegate: NSTableViewDelegate {
    func tableView(_ tableView: NSTableView, didClickRow row: Int, didClickColumn: Int)
}

Then I added an extension to the NSTableView to compute the index of the clicked NSTableViewCell

extension NSTableView {
    open override func mouseDown(with event: NSEvent) {
        let localLocation = self.convert(event.locationInWindow, to: nil)
        let clickedRow = self.row(at: localLocation)
        let clickedColumn = self.column(at: localLocation)

        super.mouseDown(with: event)

        guard clickedRow >= 0, clickedColumn >= 0, let delegate = self.delegate as? NSTableViewClickableDelegate else {
            return
        }

        delegate.tableView(self, didClickRow: clickedRow, didClickColumn: clickedColumn)
    }
}

To be able to use this extension you just need to implement NSTableViewClickableDelegate instead of NSTableViewDelegate and use the additional method it provides.

Making copy & paste work with NSTextField

When I started working on my open-source Localization Editor, which is a macOS application, I encountered some things that were a bit strange compared to iOS development. One of those things is that copy & paste does not automatically work on a NSTextField.

To be exact, copy & paste works on a NSTextField as long as you do not delete the Edit menu from the standard Main menu. If you do that for some reason, you have to implement all the copy & paste functionality yourself.

The key to the implementation is overriding the performKeyEquivalent method and manually checking for cmd + c/v/x/z/a

final class EditableNSTextField: NSTextField {

    private let commandKey = NSEvent.ModifierFlags.command.rawValue
    private let commandShiftKey = NSEvent.ModifierFlags.command.rawValue | NSEvent.ModifierFlags.shift.rawValue

    override func performKeyEquivalent(with event: NSEvent) -> Bool {
        if event.type == NSEvent.EventType.keyDown {
            if (event.modifierFlags.rawValue & NSEvent.ModifierFlags.deviceIndependentFlagsMask.rawValue) == commandKey {
                switch event.charactersIgnoringModifiers! {
                case "x":
                    if NSApp.sendAction(#selector(NSText.cut(_:)), to: nil, from: self) { return true }
                case "c":
                    if NSApp.sendAction(#selector(NSText.copy(_:)), to: nil, from: self) { return true }
                case "v":
                    if NSApp.sendAction(#selector(NSText.paste(_:)), to: nil, from: self) { return true }
                case "z":
                    if NSApp.sendAction(Selector(("undo:")), to: nil, from: self) { return true }
                case "a":
                    if NSApp.sendAction(#selector(NSResponder.selectAll(_:)), to: nil, from: self) { return true }
                default:
                    break
                }
            } else if (event.modifierFlags.rawValue & NSEvent.ModifierFlags.deviceIndependentFlagsMask.rawValue) == commandShiftKey {
                if event.charactersIgnoringModifiers == "Z" {
                    if NSApp.sendAction(Selector(("redo:")), to: nil, from: self) { return true }
                }
            }
        }
        return super.performKeyEquivalent(with: event)
    }
}

Switching my Hackintosh from NVIDIA to AMD because of Mojave

When I turned my computer into a Hackintosh about 2 years ago I was using an NVIDIA GTX 660 as my GPU and it worked without any additional drivers because of built-in support in Sierra. When I later bought a 4K display I could not make the GTX 660 drive the display at 4K@60Hz in macOS, although it worked well in Windows.

NVIDIA web drivers

I decided I needed a more powerful GPU anyway to play games on the new display in Windows so I bought a GTX 1060. It worked in Sierra and High Sierra thanks to the so called web drivers; GPU drivers provided my NVIDIA on their website. Without the web drivers you get no hardware acceleration, no 4K as maximum resolution, just one display working … the whole setup is basically unusable.

Those web drivers are version specific, every time the macOS build number changes after some update you need new ones (or to use a script to patch the previous ones). This is a bit annoying, you typically have to wait a few days after every macOS update for new drivers to become available and update then.

No web drivers for Mojave

When a new major version of macOS comes out, like Mojave, you cannot use web drivers for the previous version. NVIDIA needs to release new drivers and they now cannot do it without cooperation from Apple. Citing from the NVIDIA Developer forums

Developers using Macs with NVIDIA graphics cards are reporting that after upgrading from 10.13 to 10.14 (Mojave) they are experiencing rendering regressions and slow performance. Apple fully controls drivers for Mac OS. Unfortunately, NVIDIA currently cannot release a driver unless it is approved by Apple.

Apple basically blocks NVIDIA from releasing web drivers for Mojave, that is the reason the drivers are not out even now half, a year after Mojave release. If you are for example an iOS developer, XCode 10.2, the next version of Xcode, will only run on Mojave and you will not be able to use it unless you upgrade.

AMD GPUs in Mojave

Mojave natively supports some GPUs from AMD. You can buy a RX 560, RX 570, RX 580, Vega 56 or Vega 64 and it should work out of the box, no extra drivers needed. You not even have to install Lilu or Whatevergreen.
