Software: Apple silicon Native vs. Intel-based<\/h2>\n\n\n\n
The most important thing you can do to get maximum performance on macOS 27 is to make sure all your third-party software is Apple silicon native.<\/p>\n\n\n\n
The Intel-based Mac era is over, and if you\u2019re running macOS 27, then you\u2019re on a Mac with Apple silicon. However, there are still older versions of software, both apps and plugins, that are Intel-based. Most Intel-based software will run on macOS 27 acceptably well using the Rosetta emulation environment, but this won\u2019t take advantage of all the processing power available. You\u2019ll see a significant boost in performance when you replace an Intel-based app or plugin with the manufacturer\u2019s newest Apple silicon native or universal binary version.<\/p>\n\n\n\n
![\"Support](\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2026\/09\/Intel-Ending-Screenshot-949x1024.jpg\")
<\/a><\/figure><\/div>\n\n\n\nThe Intel-based Apps list in macOS 27 System Settings.<\/em><\/p>\n\n\n\n
macOS 27 has a feature that reveals a list of Intel-based apps on your system, those that load at startup and those that you have launched recently. To access this list, go to System Settings > General > About > macOS > Intel-based Apps<\/strong>, and click \u201cDetails.\u201d<\/p>\n\n\n\n
You can also find a more detailed table by generating a System Information<\/strong> report.<\/p>\n\n\n\n
Hold down the Ctrl key while clicking on the Apple menu in the upper left of your screen and select \u201cSystem Information.\u201d In the report, navigate to Software > Applications<\/strong>, and click on the \u201cKind\u201d column. Look for \u201cIntel.\u201d<\/p>\n\n\n\n
However, neither report will alert you that you have Intel-based plugins<\/strong> installed. For that, you\u2019re better off visiting the support website for the manufacturer of each plugin to confirm whether they have a new version you can install that is Apple silicon native.<\/p>\n\n\n\n
Sweetwater provides up-to-date information from over 200 manufacturers and developers, with links to their support websites, at our macOS 27 Golden Gate Compatibility Guide<\/a>.<\/p>\n\n\n\n
<\/div>Updating to Apple silicon native software has another imperative: macOS 27 is the final version of macOS that will run Intel-based software. Any remaining Intel-based software on your system will not run at all when you upgrade to macOS 28 next year.<\/p>\n\n\n\n

<\/div>Turn Off Backup Apps: Time Machine, Cloud-based Storage & iCloud Drive<\/h2>\n\n\n\n
Making backups of your work, locally or in the cloud, is essential. However, when backup apps are running, they can cause glitches in recording, editing, and rendering audio and video. While you\u2019re tracking, your system is writing large amounts of data to your drive continuously. When backup apps are running, they constantly search your hard drive for new data, which they then read off the hard drive and copy elsewhere. That\u2019s where glitches arise.<\/p>\n\n\n\n
Before you begin each session, disable all backup apps. When your session is finished, remember to turn on the backup apps again so they can secure your work with another incremental backup.<\/p>\n\n\n\n
Turn Off Time Machine<\/em><\/h3>\n\n\n\n
Sweetwater recommends that you keep an external hard drive connected to your Mac and configure it for backups using Apple\u2019s Time Machine<\/a>. Here\u2019s how to pause Time Machine during a session.<\/p>\n\n\n\n
- Go to System Settings > General > Time Machine<\/strong>.<\/li>
- Select your Time Machine backup disk. Click \u201cOptions<\/strong>.\u201d<\/li>
- Under \u201cBackup frequency,\u201d select \u201cManually<\/strong>.\u201d This will pause the process.<\/li><\/ol>\n\n\n\n
When your session is done, change the backup frequency to \u201cAutomatically Every Hour<\/strong>,\u201d and it will resume.<\/p>\n\n\n\n
Learn more in our SweetCare macOS Time Machine Backup Guide<\/a>.<\/p>\n\n\n\n
Turn Off Dropbox, Microsoft OneDrive, Google Drive & Other Services<\/em><\/h3>\n\n\n\n
If you use another cloud-based file-syncing service, then you must turn it off during a session. Consult the service\u2019s instructions.<\/p>\n\n\n\n
To be on the safe side, it\u2019s best not to save your working audio and video project files to a folder that is synced by one of these services as glitches may result.<\/p>\n\n\n\n
Turn Off Cloud-based Backup Services<\/em><\/h3>\n\n\n\n
Likewise, if you use a third-party cloud-based backup service such as Carbonite, IDrive, or Backblaze, then you must turn it off during a session. Consult the service\u2019s instructions. Remember to turn it back on when your session is done.<\/p>\n\n\n\n
iCloud Drive<\/em><\/h3>\n\n\n\n
iCloud Drive, a component of Apple\u2019s iCloud file synchronization service, requires special consideration for content creators.<\/p>\n\n\n\n
Apple encourages users to subscribe to iCloud and to use it to sync and share data across multiple devices. It\u2019s useful for your Photos, Messages, Mail, Passwords and other kinds of data.<\/p>\n\n\n\n
However, if you use your Mac to record and edit audio and video, don\u2019t enable iCloud Drive\u2019s \u201cDesktop & Documents Folders\u201d feature, which constantly backs up everything written to your startup disk in those home directories.<\/p>\n\n\n\n
As we\u2019ve explained, it\u2019s important not to record data to project folders that are being backed up to cloud storage, as this can lead to data loss while tracking, recording, and editing. As there\u2019s no effective means of pausing iCloud once it\u2019s configured, any data thus recorded may encounter such loss.<\/p>\n\n\n\n
No matter how you choose to use iCloud, as a general principle, it\u2019s best to record project data to an external hard drive and not your startup disk, and to have a backup strategy for those external drives.<\/p>\n\n\n\n
For an in-depth look at managing your projects on external hard drives, here\u2019s our SweetCare File Management for Music Production<\/a> article.<\/p>\n\n\n\n

Quit Unneeded Apps & Restart Your Mac<\/h2>\n\n\n\n
![\"Tahoe-Restart-Dialog\"](\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2026\/09\/Tahoe-Restart-Dialog.jpg\")
<\/a><\/figure><\/div>\n\n\n\nThe Restart dialog<\/em><\/p>\n\n\n\n
The simplest, most effective thing you can do to maximize your computer\u2019s resources is to quit all the apps you are not using. Apps you leave running take up space in memory and take away from the computing power available to your music and audio work. Apps you leave open may also run background processes or download data from the internet, and this may also interfere with recording and rendering audio and video.<\/p>\n\n\n\n
Before each session, restart your Mac. Pull down the Apple menu and choose \u201cRestart<\/strong>.\u201d You\u2019ll see a dialog that asks, \u201cAre you sure you want to restart your computer now?\u201d Uncheck<\/strong> the box next to \u201cReopen windows when logging in,\u201d and then click \u201cRestart<\/strong>.\u201d<\/p>\n\n\n\n
When you log back in, don\u2019t launch apps you don\u2019t need for your session.<\/p>\n\n\n\n
Connect Your Audio Interface Directly to Your Mac<\/h2>\n\n\n\n
USB audio interfaces require the highest bandwidth, so they function best when connected directly to a port on your Mac, not to a USB hub or a Thunderbolt dock. Connect your other peripherals through a powered hub.<\/p>\n\n\n\n
Using a MacBook? Plug It In<\/h2>\n\n\n\n
A MacBook with Apple silicon provides excellent performance while on the battery, but you can still get higher performance when your MacBook is plugged in to power.<\/p>\n\n\n\n
Turn Off Bluetooth If You Don\u2019t Need It<\/h2>\n\n\n\n
Bluetooth constantly sends signals that take up a small part of your processor\u2019s overhead. If you aren\u2019t using Bluetooth while working with your audio software, then go to System Settings > Bluetooth<\/strong> and turn it off. You can also turn off Bluetooth from the menu bar in the Command Center.<\/p>\n\n\n\n
Network & Internet Connections: Ethernet & Wi-Fi<\/h2>\n\n\n\n
If you don\u2019t need to have your Mac connected to the internet when using your DAW and plugins, then you will get higher performance and reduce the risk of glitches by disconnecting from the internet altogether. However, many users need to remain connected for software authentication (for example, with products that use iLok Cloud) or other reasons.<\/p>\n\n\n\n
When you need a local network or internet connection while recording, you will get better performance if you use an Ethernet cable connection to your router instead of Wi-Fi. This is because Wi-Fi not only has lower bandwidth but also generates network traffic that can interfere with recording and playback. When you use an Ethernet cable connection, turn your Wi-Fi off.<\/p>\n\n\n\n
MacBook computers don\u2019t have an Ethernet port, but you can use an Ethernet-to-USB-C or Thunderbolt adapter or connect to a USB or Thunderbolt dock that has a built-in Ethernet port.<\/p>\n\n\n\n
To disable Wi-Fi on your Mac:<\/p>\n\n\n\n
- Go to System Settings > Wi-Fi<\/strong>.<\/li>
- Click the button to turn it off.<\/li><\/ol>\n\n\n\n
You can also turn off Wi-Fi in the Menu Bar using the Wi-Fi or Control Center icons.<\/p>\n\n\n\n
Optimizing to Reduce Network Activity<\/h2>\n\n\n\n
When you are connected to the internet, many apps and background processes constantly create network traffic that can reduce performance. We\u2019ll discuss tips for reducing this.<\/p>\n\n\n\n
Quit Web Browsers<\/em><\/h3>\n\n\n\n
Leaving tabs open in your web browser takes up memory and processing power. Open webpages may constantly fetch data from the internet, creating more network traffic that can interfere with recording.<\/p>\n\n\n\n
Quit Email<\/em><\/h3>\n\n\n\n
Quit the Mail app or any other email app. They continuously check for new emails and download them, creating more network traffic.<\/p>\n\n\n\n
Quit Widgets<\/em><\/h3>\n\n\n\n
Quit all apps and widgets such as News or Weather.<\/p>\n\n\n\n
System Settings<\/h2>\n\n\n\n
Within System Settings, there are many controls you can adjust. Some of these are suggestions you may wish to try if you encounter problems with recording. Other settings offer slight performance gains.<\/p>\n\n\n\n
Disable macOS Automatic Updates<\/em><\/h3>\n\n\n\n
![\"macOS](\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2026\/09\/macOS-27-Disable-Automatic-Updates.jpg\" "\\"aligncenter\\"")
<\/a><\/figure><\/div>\n\n\n\nDisabling automatic updates in System Settings.<\/em><\/p>\n\n\n\n
By default, macOS updates itself automatically. This often involves downloading gigabytes of software, running processor-intensive background processes, and causing your Mac to reboot.<\/p>\n\n\n\n
Updating to newer point releases, such as from macOS 27.0 to macOS 27.2, is generally a good idea. However, experience has shown that, on rare occasion, these updates introduce incompatibilities with your DAW or other software.<\/p>\n\n\n\n
macOS frequently installs small but important system data files and security updates in the background without notifying you. It\u2019s possible that these updates can cause glitches if you\u2019re recording while your system is installing a patch.<\/p>\n\n\n\n
If you want control over this, then you can configure your Mac not to update automatically. Then, while you aren\u2019t in the middle of a project, you can decide when it\u2019s convenient to install updates.<\/p>\n\n\n\n
To disable automatic updates:<\/p>\n\n\n\n
- Go to System Settings > General > Software Update<\/strong>.<\/li>
- Click the information icon<\/strong> next to \u201cAutomatic Updates.\u201d<\/li><\/ol>\n\n\n\n
The options are:<\/p>\n\n\n\n
- Download new updates when available<\/li>
- Install macOS updates<\/li>
- Install system data files and security updates<\/li><\/ul>\n\n\n\n
Click the buttons to turn off the options then click \u201cDone<\/strong>.\u201d<\/p>\n\n\n\n
You can go back to Software Update anytime and click \u201cCheck for Update<\/strong>.\u201d macOS will notify you what updates are available, and you can decide whether to install them at that time.<\/p>\n\n\n\n
Sleep & Wake Settings<\/em><\/h3>\n\n\n\n
Macs are optimized to conserve battery life and energy usage by reducing processor power and putting disks to sleep when not in use. For audio and video, you can maximize performance by disabling these features.<\/p>\n\n\n\n
For MacBook<\/h4>\n\n\n\n
- Go to System Settings > Battery > Options<\/strong>.<\/li>
- Make sure Low Power Mode<\/strong> is off by setting to \u201cNever<\/strong>.\u201d<\/li>
- Turn off \u201cPrevent automatic sleeping on power adapter when the display is off.\u201d<\/li><\/ol>\n\n\n\n
For Desktop Mac<\/h4>\n\n\n\n
Go to System Settings > Energy<\/strong>.<\/p>\n\n\n\n
- Make sure Low Power Mode<\/strong> is off.<\/li>
- Turn on \u201cPrevent automatic sleeping when the display is off.\u201d<\/li>
- Turn off \u201cPut hard disk to sleep when possible.\u201d<\/li><\/ol>\n\n\n\n
Learn more in the Apple support article Set sleep and wake settings for your Mac<\/a>.<\/p>\n\n\n\n
Disable Unused Network Adapters<\/em><\/h3>\n\n\n\n
Your Mac may be configured with software network interfaces on USB or Thunderbolt that you don\u2019t use. They may interfere with data transmitted on those buses, so it\u2019s best to disable them.<\/p>\n\n\n\n
Don\u2019t disable the interfaces that you are currently using for Ethernet and Wi-Fi.<\/p>\n\n\n\n
- Go to System Settings > Network<\/strong>.<\/li>
- Click on a network interface you don\u2019t use (for example, Thunderbolt Bridge<\/strong>).<\/li>
- In the next pane, click \u201cMake Inactive<\/strong>\u201d or \u201cDelete Service<\/strong>.\u201d<\/li>
- Repeat for any additional interfaces.<\/li><\/ol>\n\n\n\n
Firewall<\/em><\/h3>\n\n\n\n
IMPORTANT!<\/strong> You may decide to disable the Firewall on your Mac when you are on your home network behind your router, but for security reasons, you should enable the Firewall when you travel with your Mac and connect to other networks.<\/p>\n\n\n\n
Some audio interface manufacturers recommend that you disable the Firewall<\/strong> on your Mac because it can create network activity that may cause dropouts in audio recording and playback. Some users believe it\u2019s better to configure your studio\u2019s router to perform all firewall functions instead.<\/p>\n\n\n\n
However, your Mac\u2019s Firewall serves an important purpose, protecting your system from network intrusion. We recommend that you leave your Mac Firewall turned on.<\/p>\n\n\n\n
If you encounter audio dropouts, then disabling your Mac Firewall is a troubleshooting step you can try.<\/p>\n\n\n\n
With the Firewall enabled, you have many options for disabling or enabling specific kinds of network connections.<\/p>\n\n\n\n
Learn more in the Apple support article Change Firewall settings on Mac<\/a>.<\/p>\n\n\n\n
Location Services<\/em><\/h3>\n\n\n\n
Certain apps continuously broadcast your location to services on the internet. Apart from privacy concerns, this additional network traffic may interfere with recording.<\/p>\n\n\n\n
You can turn off Location Services altogether during a session to prevent this network traffic. You can also disable Location Services for individual apps.<\/p>\n\n\n\n
Go to System Services > Privacy & Security > Location Services<\/strong>. Across from \u201cLocation Services,\u201d click the large button to turn off the feature globally, for all apps.<\/p>\n\n\n\n
If you don\u2019t wish to disable the entire service, then you can disable Location Services for each app individually.<\/p>\n\n\n\n
Under \u201cSystem Services<\/strong>,\u201d click \u201cDetails<\/strong>\u201d to configure specific settings for the services that macOS uses.<\/p>\n\n\n\n
Note that turning off Location Services will prevent your Mac from being tracked in the Find My <\/strong>app. For more information, see Apple support: Set up the Find My app to locate a missing Mac, device or item<\/a>.<\/p>\n\n\n\n
Learn more in the Apple support article Manage Location Services settings<\/a>.<\/p>\n\n\n\n
Analytics & Improvements<\/em><\/h3>\n\n\n\n
Apple collects diagnostic and usage data while you use your Mac. When you first use a service, you are prompted for permission for Apple to upload this data or send it to third parties.<\/p>\n\n\n\n
For example, if you enable \u201cImprove Siri & Apple Intelligence,\u201d then you grant Apple the right to upload, collect, and use your text and audio interactions with Siri, Dictation, and Translate, submitted anonymously, to help improve the accuracy of their services.<\/p>\n\n\n\n
If you experience a crash, then you may see a \u201cShare with app developers\u201d dialog asking permission to send a crash log to the developer.<\/p>\n\n\n\n
As these create network traffic, you may wish to turn off each option.<\/p>\n\n\n\n
- Go to System Settings > Privacy & Security > Analytics & Improvements<\/strong>.<\/li>
- Turn off the individual options.<\/li><\/ol>\n\n\n\n
Login Items & Extensions<\/em><\/h3>\n\n\n\n
Software services that load automatically when you log in to your Mac run continuously in the background and perform various functions that involve creating network traffic while they take up small amounts of memory and processing power. You can disable items individually.<\/p>\n\n\n\n
Go to System Settings > General > Login Items & Extensions<\/strong>.<\/p>\n\n\n\n
You\u2019ll see three sections.<\/p>\n\n\n\n
Open at Login<\/h4>\n\n\n\n
You can add or delete any app.<\/p>\n\n\n\n
Background App Activity<\/h4>\n\n\n\n
Many apps you install come with hidden background processes that run continuously and do things including sync data and download updates. Disable the ones you don\u2019t need. You may wish to turn these back on when you are not working on a project.<\/p>\n\n\n\n
Extensions<\/h4>\n\n\n\n
Extensions add extra functionality across your Mac in contextual menus and the like, but some also run in the background. Turn off the ones you don\u2019t need during a project.<\/p>\n\n\n\n
System Sounds & Notifications<\/em><\/h3>\n\n\n\n
While this has little to do with increasing performance, you don\u2019t want to be distracted by your Mac while working in your DAW.<\/p>\n\n\n\n
System Sounds<\/h4>\n\n\n\n
- Go to System Settings > Sound<\/strong>.<\/li>
- Turn Alert Volume<\/strong> all the way down. Turn off \u201cPlay user interface sound effects\u201d and \u201cPlay feedback when volume is changed.\u201d<\/li><\/ol>\n\n\n\n
Application Notifications<\/h4>\n\n\n\n
macOS 27 has a vast system of notifications using badges, sounds, and banners on your desktop and in the Notification Center for all kinds of apps and events. You have a great deal of specificity in limiting them or turning them off for each app.<\/p>\n\n\n\n
Go to System Settings > Notifications > Application Notifications<\/strong>.<\/p>\n\n\n\n
You\u2019ll see a list of apps. Click on each entry and turn off the notification that you don\u2019t wish to see.<\/p>\n\n\n\n

Activity Monitor: CPU Load & Memory Pressure<\/h2>\n\n\n\n
![\"Tahoe-Activity-Monitor-CPU\"](\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2026\/09\/Tahoe-Activity-Monitor-CPU-1024x683.jpg\")
<\/a><\/figure><\/div>\n\n\n\nThe macOS Activity Monitor.<\/em><\/p>\n\n\n\n
Most DAWs have a \u201cperformance monitor\u201d or \u201cCPU overload indicator\u201d to alert you when your session overwhelms your hardware, causing hang-ups, glitches, or noise. However, this only reports on resources within your DAW.<\/p>\n\n\n\n
Apple provides the Activity Monitor<\/strong> app, which gives a real-time display of all running apps and processes across your entire Mac. Activity Monitor displays how much of your computer\u2019s resources are being used in five categories: CPU, Memory, Energy, Disk, and Network.<\/p>\n\n\n\n
It\u2019s useful to check Activity Monitor while you are running your DAW to observe stresses on your system. You can use this to identify apps and processes that are taking up resources so you can quit or disable them.<\/p>\n\n\n\n
Go to Applications > Utilities > Activity Monitor<\/strong>.<\/p>\n\n\n\n
Under the CPU<\/strong> tab, click on the \u201c% CPU\u201d column. The list will sort according to the processes using the most CPU power. The CPU Load<\/strong> graph indicates the total amount of resources being used.<\/p>\n\n\n\n
Under the Memory<\/strong> tab, click the \u201cMemory\u201d column to sort by processes that use the most memory. The Memory Pressure<\/strong> graph indicates how much memory is in use. If the apps you are running exceed the amount of memory you have, then a value appears in the Swap Used<\/strong> field, indicating that your system must write data to and from the startup disk to make up for the shortfall in memory. This indicates that your system is currently overburdened.<\/p>\n\n\n\n
