    Use serverinfo in macOS Server 5.2 for Sierra

    macOS Server 5.2 (for Sierra)  comes with the /usr/sbin/serverinfo command (introduced in Mountain Lion Server). The serverinfo command is useful when programmatically obtaining information about the very basic state of an Apple Server. The first option indicates whether the Server app has been downloaded from the app store, which is the –software option: serverinfo --software When used, this option reports the following if the Server.app can be found: This system has server software installed. Or if the software cannot be found, the following is indicated: This system does NOT have server software installed. The –productname option determines the name of the software app: serverinfo --productname If you change the name of…

    Create A Bootable macOS Sierra Installer

    A bootable installer is one of the fastest ways to install a Mac. Rather than copy the installer to a local drive you can run it right off a USB disk (or Thunderbolt if you dare). Such a little USB drive would be similar to the sticks that came with the older MacBook Air, when we were all still sitting around wondering how you would ever install the OS on a computer with no optical media or Ethernet otherwise. Luckily, Apple loves us. To make a bootable USB/flash drive of Sierra like the one that used to come with the MacBook Air, first name the USB drive. I’ll use mavinstall for…

    Change Xcode Log Paths In macOS Server 5.2

    The logs in Xcode Server (Server 5.2 for Sierra) by default point to /Library/Server/XcodeLogs/credserver.log. This takes all of the output from xcscredd and xcscredhandler. If you’re doing a lot of debugging then logs can be pointed to another location, such as another drive. The path to the logs is defined in the /Applications/Server.app/Contents/ServerRoot/System/Library/LogConfiguration directory. The file to edit is a standard property list, XCSCredentialServer.plist: <?xml version=”1.0″ encoding=”UTF-8″?> <!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”> <plist version=”1.0″> <dict> <key>claimedFacilities</key> <array> <string>servermgrd</string> <string>servermgr-listener</string> <string>servermgr-notify</string> </array> <key>claimedSenders</key> <array> <string>servermgrd</string> <string>servermgr-listener</string> <string>servermgr-notify</string> </array> <key>logMaximumLevel</key> <string>debug</string> <key>logPath</key> <string>/Library/Server/Logs/servermgrd.log</string> </dict> </plist> Once open, look for a key called logPath. Change that to the desired path, such…

    Clear nvram In macOS Sierra

    OS X has the ability to delete all of the firmware variables you’ve created. This can get helpful if you’ve got a bunch of things that you’ve done to a system and want to remove them all. If you run nvkram followed by a -p option you’ll see all of the configured firmware variables: nvram -p If you run it with a -d you’ll delete the given variables that you define (e.g. boot-args): nvram -d boot-args But, if you run the -c you’ll wipe them all: nvram -c

    App Store Preferences To Set In On Server 5.2 for macOS Sierra

    By default, OS X now updates apps that are distributed through the Mac App Store (MAS). Server running on macOS Sierra is really just the Server app, sitting on the App Store, installed on a standard Mac. If the Server app is upgraded automatically, you will potentially experience some adverse side effects, especially if the app is running on a Metadata Controller for Xsan, runs Open Directory, or a major release of the Server app ships. Additionally, if you are prompted to install a beta version on a production system, you could end up with issues. Therefore, in this article we’re going to disable these otherwise sweet features of OS X.…

    Capture Smaller Screenshots On Retina Displays In Sierra

    By default, screenshots are pretty big on a retina display on a Sierra machine. Like about 4 times the size they should be. I haven’t found a defaults key I can use yet to reduce them, so I’ve been using this little screenshotting app called RetinaCapture, available at https://gumroad.com/l/retinacapture. Basically, when you’re running it, you just open it up and click on the Window button. There, you can select a window to screenshot. Once you’ve selected the window, you’ll be prompted to save it somewhere with a name. I don’t love having to use any 3rd party apps for my screenshotting workflow. In fact, it bugs the crap out of me. Screens get resized…

    Upgrade from OS X to macOS Sierra

    Installing OS X has never been easier than it got in Yosemite, when the installers were moved to the App Store. And since then it’s just gotten easier, and easier. In this article, we’ll upgrade a Mac from OS X 10.11 (El Capitan) to macOS Sierra (10.12), the latest and greatest. The first thing you should do is clone your system (especially if you’re upgrading a server). The second thing you should do is make sure you have a good backup. The third thing you should do is make sure you can swap back to the clone should you need to do so and that your data will remain functional on the…

    Setup And Manage Profile Manager On macOS Server 5.2

    Profile Manager first appeared in OS X Lion Server as the Apple-provided tool for managing Apple devices, including Mobile Device Management (MDM) for iOS based devices as well as Profile management for OS X based computers, including MacBooks, MacBook Airs, Mac Minis, Mac Pros and iMacs running Mac OS X 10.7 and up. Profile Manager has seen a few more updates over the years, primarily in integrating new MDM options provided by Apple and keeping up with the rapidly changing MDM landscape. Apple has added DEP functionality, content distribution, VPP, and other features over the years. In El Capitan Server, there are plenty of new options, including the ability to deploy…

    Disable ICMP Rate Limiting In OS X

    Ever wonder why repetitive pings fail after a little while in OS X (e.g. those sent via the -f flag)? By default, OS X has an ICMP rate limit of 250 set. You can increase this or disable, using sysctl. To disable, set the value of net.inet.icmp.icmplim sudo sysctl -w net.inet.icmp.icmplim=0 Happy icmp flooding!
