Here’s detailed steps on how to install macOS High Sierra on a hackintosh using the Clover method with the HFS Method. Apple introduced a new file system called Apple File System (APFS). When High Sierra is installed the drive is automatically converted over to APFS, but there is a way to disable it easily and keep the drive as HPFS by editing an XML file during the install.
If the sound on your Mac has stopped working, there are a number of possible explanations and solutions. The first thing to check is that the sound definitely is not working. Below we'll explain what to check.
No sound on Mac? Check these things first
1. Check the volume
As simplistic as it may seem, the first thing to check is that the volume hasn’t been muted intentionally. Tap the volume up (F12) key to turn up the sound level.
Pro tip: If you hold down Option+Shift when you press F12 or F11 to increase or decrease the volume, it will move in smaller increments than the full step changes that occur when you use the keys on their own.
2. Is it an app problem?
It may be that there’s no sound on your Mac because it won’t play audio in a specific app. If, for example, you can’t hear sound from a video in Safari, make sure the audio isn’t muted, by clicking the volume control in the video. You should also check other sound sources, like iTunes and QuickTime movies to find out if they can play sound.
Tip: if you’re fed up with websites you visit automatically playing video with sound when you’re working, go to Safari>Preferences and click the Websites tab. Click Autoplay, and in the bottom right of the window, choose Stop Media with Sound.
3. Check for hardware issues
Next, check there’s nothing plugged into the headphone/line out port and look to see if there’s a red light on that port. If there is, it could be there’s a problem with the port, or something blocking it. Try blowing on it to clear dust, if that’s the case.
4. Are you running the latest version of macOS?
If there’s still no sound on your Mac, Apple’s advice is that the first thing you should do is make sure you’re running the latest version of macOS.
To check which version of macOS your Mac is running, click the Apple menu and then About this Mac. The window that opens will have the name of the version of macOS currently installed at the top. Now the latest version is macOS High Sierra. If you’re not running High Sierra, you should consider installing it by going to the App Store app, and clicking on it in the sidebar on the right hand side of the main window.
If you don’t want to install High Sierra, at least make sure you’re running the latest update to whichever version of the OS is installed. To check that, click Software Update in the About this Mac window. That will check for updates and let you know if there’s one available. If there is, install it.
Before you install either a new version of the OS or an update, backup your Mac using Time Machine, or whichever backup tool you normally use.
5. Run Maintenance scrips
If you’ve determined your Mac’s sound definitely isn’t working, consider running CleanMyMac X’s Maintenance scripts. These optimize the performance of your Mac by running a number of routines such as repairing disk permissions, verifying your startup disk, and rebuilding the launch services database.
Here's how to run Maintenance scrips:
Download CleanMyMac X here (it's free to download).
- Launch the app.
- Click Maintenance.
- Choose Run Maintenance Scripts and click Run.

How to check your sound settings
If you’re running the latest version of macOS and your sound still isn’t working, the next step is to check your Sound settings.
- Click on the Apple menu and choose System Preferences.
- Click on the Sound pane.
- Select the Output tab and choose Internal Speakers. If that’s not available as an option, contact Apple Support.
- Check if the volume slider is low, if so slide it to the right and check the sound again.
- Make sure the Mute box isn’t checked.
If, when you check your sound settings, you see a USB device selected rather than Internal Sound, and you can’t change it, disconnect all USB devices from your Mac and try again.
Is there an app interfering with the sound?
Some applications, like screen recorders, install their own audio output drivers so that when you record the screen you can direct your Mac’s output to the recording app. It’s possible that if you’ve installed an app like that, its driver could be interfering with your Mac’s sound output.
- Go to System Preferences and choose Sound.
- Click on the Output tab.
- If there’s an output option that looks like a software app and it’s selected, that may be why the sound is not working on your Mac.
The best thing to do in that instance is to uninstall the app. You could just drag the app to the Trash, but that won’t uninstall it properly or remove all the files the app has placed on your Mac. To do that, you should use a dedicated uninstaller like CleanMyMac X.
CleanMyMac makes it very easy to completely uninstall any app so that it doesn’t leave any fragments or stray files behind. By using CleanMyMac, you can be sure you’ve deleted all the files associated with the app and that it hasn’t left anything behind. You can download CleanMyMac for free here.
Restart the sound controller
If there are no software audio drivers interfering with your Mac’s sound output, nothing plugged into the headphone jack, USB, or Thunderbolt ports, and your sound still doesn’t work, the next step is to restart the sound controller. This requires launching Activity Monitor and quitting a process, but don’t worry, it’s not too scary! Mac key finder app.
- Go to Applications>Utilities and double-click on Activity Monitor to launch it.
- In the search bar, type 'coreaudiod’ to locate the Core Audio controller.
- Click on coreaudiod, then click ‘X’ in the tool bar to quit it.
- Coreaudiod will restart.
Mac volume not working and stuck on mute?
If the volume control is not working on your Mac, either using the keyboard or the slider in the menu bar or System Preferences, it could be ’stuck’ on mute. The most common occurrence of this problem is on pre-2015 Macs that had a digital audio output support in the headphone jack.
On those Macs, there was a sensor in the port that detected whether a headphone jack or a digital audio device was plugged in. The Mac would then change the output to headphones or digital output accordingly. However, sometimes the sensor failed to recognise when a digital audio device had been unplugged and so the audio output remained locked on digital output, with no way to change it. With no digital audio output connected, there is no way to change the volume or hear sound.
The solution in that case is to plug the cable back in to the socket and remove it again. Try it a few times, if necessary, to ‘trip’ the sensor and make the Mac recognise the digital audio device is no longer connected. If that doesn’t work, there could be some gunk blocking the socket. Try blowing on it to remove any dust. If that doesn’t work, buy a can of compressed air and, carefully, spray the socket to bow out the dust.
If that still doesn’t do the trick, buy a foam-tipped swab (don’t use a cotton bud as these leave tiny threads behind) and dip it in rubbing alcohol. Put the swab into the headphone jack and clean it, wiping away as much of the link as possible.
Bluetooth sound not working on Mac
Your Mac can play audio wirelessly via Bluetooth, so if you have Bluetooth speakers or headphones, you can use those to listen to music, or anything else on your Mac. Sometimes, however, they don’t work.
Make sure Bluetooth is switched on.
Sound Control App Asking Me To Install Extra Mac Osx
- Go to System Preferences and click the Bluetooth pane.
- If it says Bluetooth turned off, turn it on.
Make sure your headphones or speakers are connected.
- Look in the list of devices in the main window to see if your headphones or speakers are listed.
- If not, put them in pairing mode (you’ll need to refer to their instructions to find out how to do that) and when they appear, click Connect.
- If they are listed but not connected, make sure they’re switched on and Control-click on them in the main window and choose Connect.
Tip: If you check the box labelled Show Bluetooth in menu bar in Bluetooth preferences, you can connect from the menu bar item.
Once your headphones or speakers are connected, click on the volume control in the menu bar and choose them. If you don’t have the volume control displayed on the menu bar, go to System Preferences, choose Sound and then the Output tab and select the Bluetooth speaker or headphones. While you’re there, it’s a good idea to check the box labelled Show volume in menu bar — it’s in the Sound Effects tab.
To conclude, there are a number of reasons why the sound is not working on your Mac. If you follow the guide above and take it one step at a time, you should be able to fix the problem. If none of the steps above work for you, the next step is to contact Apple support and, if possible, make an appointment at the Genius Bar of an Apple Store. If that’s not possible, Apple will advise you on the best course of action to get your audio working again.

You can use Audio MIDI Setup to configure audio input and output devices that you use with your iMac, such as microphones and multichannel audio interfaces. Audio MIDI Setup works with many types of audio and MIDI interface devices, including your computer’s built-in audio and digital multichannel audio devices. It works with devices connected to your iMac using FireWire, USB, Bluetooth, PCMCIA, and PCI.
The settings you can change in Audio MIDI Setup depend on the audio device you’re using. For example, if the device supports volume control, you can adjust the volume for each channel your audio output device has available by following these steps:
- Connect your audio devices to your iMac. If necessary, install any software included with the devices. See the documentation that came with your audio devices.
- Open Audio MIDI Setup (you can find it in Utilities, inside your computer's Applications folder).
- Choose an audio device from the list on the left side of the Audio Devices window.
- To use the device for sound input, choose 'Use this device for sound input' from the Action pop-up menu.
- To use the device for sound output, choose 'Use this device for sound output' from the Action pop-up menu. If you also want to use the device to play system sounds, choose 'Play alerts and sound effects through this device' from the Action pop-up menu.
- On the right side of the Audio Devices window, choose the options available for the device you're setting up:
- In most cases, leave the 'Clock source' pop-up menu on the default setting.
- To set up surround (multichannel) speaker configurations, click Configure Speakers. Then, choose the type of configuration you want to use. See Set up external speakers for stereo or surround sound for more information.
- You can set the sample rate and bit depth in the Format pop-up menus. Make sure they match the appropriate settings for your audio device and that the input and output sample rates are set to the same value. For example, the built-in speakers of an iMac computer may appear like this:

- If your iMac supports the hardware sample rate converter, the Hardware Rate Converter pop-up menu is available in the Input menu. When you choose Automatic from the pop-up menu, the hardware sample rate converter is turned on if the audio samples coming in are PCM and formatted according to the international standard IEC 60958-3. The hardware sample rate converter is turned off if the input stream is encoded. You can also choose Enable or Disable from the menu to keep the hardware sample rate converter turned on or off.
If you choose Enable from the menu, you may not be able to stream non-LPCM or encoded audio because the audio may not be recognized. - If software volume control is available for your device, the Volume sliders are blue to indicate they are active. Drag the sliders to set the volume for each channel.
