FAQs
Can I change the OS on my server from macOS to Linux?

One of the benefits of the hypervisor is the ability to install multiple operating systems on one system. If your subscription is a Mac mini with quad core i7 CPU, you can run multiple virtual machines with various operating systems on the server.

In the past we installed the VMware ESXi hypervisor and created a Linux virtual machine by request. Due to the complex nature of installing Linux and the many variations available, we now offer the base VMware ESXi installation with no virtual machines included. Customers may install virtual machines on their own.

We don’t do any initial operating system customization. When you initially order a server with macOS on it, it's macOS on the bare metal Mac just as if you’d bought it at a store.

Do I have root and admin access to subscription-based Mac servers?

For every subscription to a hosted Mac running macOS, we provide an adminstrator account and the ability to modify system-level files. Login as administrator to a Mac running macOS and you have complete control over the system.

SSH and VNC access are enabled by default on dedicated servers so you can access them from any device. It's no different than if the server were on your local network.

We do require that you follow the guidelines set in our Terms of Service and Acceptable Use Policy which you must agree to during checkout.

Do I need a VNC server installed on my Mac?

One of the more popular free VNC tools used by our clients, RealVNC, now offers their server product under the name VNC Connect. Customers often ask us whether they need VNC Connect on their Mac running macOS.

Apple’s macOS also includes a built-in default VNC server. We enable this for every hosted Mac running any version of macOS before releasing the server to a customer.

To connect to one of our Mac servers running macOS, you need a VNC client like the one RealVNC offers, VNC Viewer. VNC Connect is not required.

Is there macOS software to replace the popular web hosting software offered by Linux VPS providers?

Below are some tools that allow users to exploit the power and reliability of the Apple macOS platform, and still have the familiar *NIX-type experience.

  • macOS Server by Apple is available in the App Store for $19.99 and installs as an app and service within macOS. It includes a web server among other utilities.
  • MAMP / MAMP Pro is similar to Linux LAMP. “MAMP” stands for Macintosh, Apache, MySQL and PHP. MAMP can be installed on macOS 10.10 or greater and includes a friendly user interface.
  • MACPorts is a more advanced method that provides a command-line method of installing software packages under BSD to access thousands of ports and greatly simplifies compiling and installing open-source software on your Mac.
  • HomeBrew is the latest BSD/*NIX package manager for macOS, and is a great alternative to MACPorts.

The Mac is a powerful Intel-based hardware platform that can run any OS – not just macOS.

MacStadium offers VMware ESXi as a means to install all variants of Linux as virtual machines on a hosted Mac. This includes generic distributions like Debian, Ubuntu, and CentOS, as well as packaged distributions that include software like cPanel and Plesk.

What is APFS? And what can I do with it?

APFS stands for “Apple File System,” the proprietary file system for macOS High Sierra (10.13) and later, developed and deployed by Apple. It replaces HFS+ (also known as Mac OS Extended). APFS is optimized for flash and solid-state drive storage with a primary focus on encryption.  Our friends at TidBITS put together a great article that gives some more background; read it here: https://tidbits.com/2018/07/23/what-apfs-does-for-you-and-what-you-can-do-with-apfs/

Why are coreaudiod and launchd in macOS using a high amount of resources?

Disclaimer: We are an infrastructure provider and can only offer a minimal amount of help for software issues. We can not  guarantee this fix works for all users or offer support for it. Please contact the software developer (Apple, in this case) for further help. We can also provide a list of vendors that we work with to support you.

We found a confirmed solution with the help of a customer:

"I figured out what the problem was in case you all are seeing this in other places. The bluetooth daemon had crashed. I'm not sure why that made coreaudiod and launchd go crazy, but the fix is this: 

$ sudo launchctl unload -w /system/library/launchdaemons/com.apple.blued.plist 

If the daemon crashes you may see a message like this: /System/Library/LaunchDaemons/com.apple.blued.plist: Could not find specified service. Next, run this: 

$ sudo launchctl load -w /system/library/launchdaemons/com.apple.blued.plist 

Once blued is running properly, coreaudiod and launchd both settle down."
