If you use MIDI devices or a MIDI interface connected to your Mac, you can use Audio MIDI Setup to describe the configuration of your MIDI devices. There’s a default configuration already created, but you can set up your own.
You can use this configuration information for apps that work with MIDI, such as sequencers, to control your MIDI devices.

Note: Make sure your MIDI devices are connected to your Mac. If you’re using an interface device, connect any other MIDI devices you’re using to the interface. Also check that any software provided by the manufacturer of the MIDI devices has been installed. For more information, see the documentation that came with your devices.
In the Audio MIDI Setup app on your Mac, choose Window > Show MIDI Studio.
In the MIDI Studio window, click the Choose MIDI Configuration pop-up menu (it may show Default), then choose the configuration you want to view.
In the toolbar, click the following buttons to change how the configuration is shown:
Hierarchical View : Devices in the configuration are shown as icons. If a device isn’t connected, its icon is dimmed. To view information about a device, such as channel properties and ports, and to add or remove ports, double-click the device’s icon.
List View : Devices in the configuration are shown in a list, organized by type (such as Interface or External Device). If a device isn’t connected, it’s dimmed. To filter which devices are shown, click the Show pop-up menu, then choose an option (such as Online or Connected). To view information about a device, double-click the device. To view its ports, or to connect or disconnect devices, click the device’s disclosure triangle.
In the Audio MIDI Setup app on your Mac, choose Window > Show MIDI Studio.
In the MIDI Studio window, click the Choose MIDI Configuration pop-up menu (it may show Default), then choose New Configuration.
Enter a name for the new configuration, then click OK.
To add a new external MIDI device, click the Add button in the MIDI Studio toolbar.
To set properties and add or remove ports for the MIDI device, double-click the device, or select it, then click the Device Info button in the toolbar.
In the Properties window, do any of the following:
Describe the device: Enter a name for the MIDI device; the name appears in apps you use with the device. If you know the manufacturer and model, you can enter those.
Change the device icon: Click the MIDI device’s icon to open the Icon Browser, select a different icon to represent the device, then click the new icon to close the Icon Browser.
Change the device color: Click the color well, select a different color to use for the MIDI device, then close the Colors window.

Behold, the day has come! Apple’s macOS 10.14 Mojave is out and available as a free download now
Let's start with a quick overview of what you get in the new system and why it's worth installing:
Clean install is a bit different from a regular upgrade. You’d usually simply roll the new macOS right over your old one. You get a new desktop wallpaper and all your applications and files right where you left them. Including the ones you don’t want anymore, and including some system junk left from the previous OS.
Which is why if you feel like there’s a need for a purge — in the best meaning of this word — among your files and system leftovers, it makes more sense to run an clean install. The usual reasons are: system jut has started to affect your Mac’s performance, you need to make sure your old data is cleared, you’re selling a Mac or passing it to a new owner.
Or maybe (and we get you) you just want that freshly-bought Mac experience again.
If you did a clean install of macOS High Sierra last year, here's some good news: it's pretty much the same. If you haven't, another good news: we'll take you through it step by step.
Before you do anything, check that your Mac is able to run Apple's new operating system. If you were able to run the previous macOS High Sierra with no visible issues, you're probably fine. But just in case, double-check. We'll also give you main requirements below.
To complete the clean install procedure, you'll need:
First of all, check that your Mac is compatible with new macOS. Here's a list of Macs that can run the Mojave:
You'll need at least 4 GB of free space on drive. Not too much but keep that in mind before you start.
There are a few ways to correctly run a clean install and they mainly depend on how your Mac hard drives are structured. Now, if your Mac has one single drive, not broken into parts, and it is the drive where every file you own is stationed, as well as your system, they your only choice is to clean install on the startup drive.

Keep in mind: if you proceed to do it on your startup drive, all your files and data will be permanently removed. To keep them safe, you’ll need a backup, we’ll tell you how to do it, no worried.
If your hard drive is partitioned (broken into volumes), or you have another drive, you can clean installing on a non-startup drive. This way your files are preserved, since it’s a more lenient way of OS upgrade. Only the system gets cleared and reinstalled with a new one, while the rest of the drive is left intact.
Clean install macOS, securely
Try an advanced tool for securely installing Apple's new operating system. A surefire way to clean install.
If you don’t know which one you have, go with the first option, startup drive.
Make sure you’ve got everything ready to clean install Mojave and let’s get down to business. It’s going to be easy because we’ll take you step by step through the safest way to do it.
We’re going to mention a few applications you’ll need during the process. Worry not, you won’t need to look them up on the web, and all of the apps are available on Setapp. It’s a subscription collection of Mac apps, you can use any app in there once you download it on your Mac. It has a weekly free trial, so go ahead and sign up.
Since clean installation involves wiping your Mac’s main drive, it’s vital that you back it up immediately before you start. And since some of those files are junk, backing them up would be, well, unadvisable. So it’s usually a good idea to remove extra files before the backup with a Mac cleaner, like CleanMyMac. Run it and give your High Sierra a polish before clean installing Mojave.
Time to remove every junk-looking thing you can find — old movies and media files, apps you never use, cache and system trash, duplicate files that you accidentally copied a few times. All the hard-drive-space-eaters, all have to go.
This might sound like a lot of work but it’s actually about 10 minutes when you have the right software. Open CleanMyMac
and run a full scan. This will remove system junk, old caches, and random unused files. To get rid of apps use the Uninstaller tab, and for the big media files run the Large & Old Files search.
You've probably enjoyed the ability to store images in the cloud and keep all of them despite limited space, which means you've got a lot to clean among your photos. To spot and erase those repeating images, try Gemini app. It's made to find duplicate and similar files or folders on your hard drive, so you can delete them and retrieve precious storage space.
When all of the extra files are gone and all you’ve got left on drive is what you actually need, time to back it all up. Use Get Backup Pro for the job. It’s better than Apple’s native Time Machine. Also, move your photos and document into the cloud (iCloud, Dropbox, whatever your choice is) or to an external drive, like a USB stick.
And, create a bootable clone, in case of tech issues during the upgrade. This way you’ll be able to go back to where you started easily. Plus, a cloned drive lets you quickly copy files to your new system.
Another tip: if you have any specifically customized apps that took time to set right, make screenshots of app settings. And keep a record of license codes for the apps you’ve bought to restore them when reinstalled.
By the way, if you get Setapp subscription we mentioned before — the problem with license codes will become a thing of the past. All the apps inside are fully active and packed in one suite. No separate purchases, paid upgrades, and so on.
Notice: Apple usually gets protective over previous versions and removes the installer once the next macOS is out. Which is why you might want to grab the High Sierra installer before its gone from the app store (if the link is still active, you're lucky).
Why you might need it: in case the new macOS Mojave refuses to behave on your Mac or you just don't like it, or any other problem occurs and you'll need to downgrade and clean install High Sierra back to your Mac, that's when the installer comes in handy. It's a corner case but better safe than sorry, right? Anyways, now that you have your High Sierra backup plan, you can process.
Make sure you backup your Mac to keep your important files, before taking next step, that erase your Mac’s Startup drive.
To erase your Mac’s main drive:
When the macOS Utilities screen appears, follow these steps:
After the reboot, your Mac will require setting up like a new one. Imagine you just bought it and proceed to fill in all the gaps — WiFi, iCloud with Apple ID, Dropbox, accounts, passwords. Could take a while but remember, it was worth it.
Once the initial process is done, you can start stocking up on software. To reinstall the apps from Setapp, go to setapp.com to get Setapp installer or download Setapp here.
It makes sense to only install those applications you need right now. Other apps can be downloaded later. You don’t need too much clutter on your fresh system.
Just as last year when we were doing the clean instal of High Sierra, you don’t need a backup for this option, it’s safer and faster than the previous way but only available to you if you have an extra drive or your drive is broken down into volumes.
Here’s how to instal your new macOS on the non-startup disk.
Before you install the new OS on it, you need to erase all data on the drive you’ve chosen for it.
To completely remove data with Disk Utility choose the volume you’d like to clean up and click Erase.
If you still need some info from that drive, you can use an app like Chronosync Express to sync it with another drive and keep the files.
To download the macOS Mojave installer, go to the Mac App Store > Updates tab and choose Mojave installer (Here is a direct link.) When it's ready, it's going to launch automatically. You will need to quit it at this point, we're not running it this way.
You don’t need to create a specific bootable drive, use the installer you've just downloaded and install the new macOS 10.14 onto the other drive you have.
Find the Mojave installer in your Applications folder and launch it. You’ll be offered to choose your target drive for the installation, change it from startup to the one you need. To do it, click Show All Disks and find the needed volume on the list. Finish the installation by simply following the instructions. Your OS is now ready, time to set it up. You’ll have to undergo the same process as if the Mac was totally new.
When you have the system ready, you can start filling it with applications. If you don’t enjoy looking for every app’s licence code, get Setapp. There are 120+ pro apps of high quality, all packed in one suite. Saves time and money and covers hundreds of daily Mac tasks.
