When  Apple introduced APFS  to replace the existing HFS+ system, its design was meant to herald changes to how the file system works with newer, modern technologies such as solid-state drives (SSDs). APFS was also designed to overcome inherent deficiencies in HFS+, which has been showing its age for several years. However, that doesn't mean APFS is everyone, especially considering some of its limitations, such as not being compatible with Time Machine for backups, FileVault 2 for drive encryption, or the inability to format Fusion drives with Apple's newest file system. SEE:  Complete Beginner's Guide to iOS Development: Build 10 Apps (TechRepublic Academy) If you've come to rely on any of the aforementioned technologies or require the use of a feature that is not supported by APFS but have already made the leap to using the new file system, fret not—you can revert back to HFS+ by following the simple commands below.

macOS High Sierra brings with it  a new filing system known as APFS  (Apple File System). APFS replaces HFS+ (Hierarchical File System Plus), and offers a new, modern file system that is optimized for use with SSDs (Solid State Drives), while still being usable on hard drives and, in the near future, even on tiered storage systems such as Apple’s Fusion drive. As part of the upgrade process, the macOS High Sierra installer will automatically convert an  SSD  to the new APFS. The conversion process leaves the drive’s data intact, or at least it’s supposed to;  be sure you have a recent backup before upgrading , just in case. At the time of this writing, the automatic conversion process is limited to internal SSDs.  External SSDs  being used as startup drives seem to be left with their original file system, with no conversion to APFS occurring. However, this could change with the next update to macOS High Sierra, as it seems Apple is committed to gro...

MacOS High Sierra includes the all new APFS file system, which is arguably one of the most significant new features introduced in the new Mac operating system update. Nonetheless it’s possible that some Mac owners with SSD volumes will want to  not convert the existing HFS+ file system to APFS file system when installing macOS High Sierra . With a little command line magic, you can  skip converting to APFS during the macOS High Sierra installation process  if desired. How to Install macOS High Sierra Without Converting to APFS File System This is not recommended and should only be applicable to advanced users who have specific reasons to not want to convert a Mac to APFS. APFS is faster and offers better encryption, amongst other benefits, so it’s generally recommended to use APFS if the Mac supports it. APFS is currently only supported on SSD drives, with Fusion drives support for APFS soon to arrive in a future Mac software update. How to Not Convert to APFS...

So you’re  using Disk Utility to partition your new hard drive  when you’re presented with a choice of potential file systems. The list is longer than you’d think, with terms like “APFS (Case-sensitive)” and “Mac OS Extended (Journaled, Encrypted)” to choose from. What does all this mean, and which should you choose? Basically there are three main options: RELATED ARTICLE What’s New in macOS 10.13 High Sierra, Available Now APFS , or “Apple File System,” is one of the  new features in macOS High Sierra . It’s optimized for solid state drives (SSDs) and other all-flash storage devices, though it will also work on mechanical and hybrid drives. Mac OS Extended , also known as  HFS Plus  or  HFS+ , is the file system used on all Macs from 1998 until now. On macOS High Sierra, it’s used on all mechanical and hybrid drives, and older versions of macOS used it by default for all drives. ExFAT  is the best cross platform option, designed to w...

macOS High Sierra introduces APFS (Apple File System) to Mac computers. APFS replaces Mac OS Extended (HFS+) as the default file system for solid-state drives (SSDs) and other all-flash storage devices.        Which format is in use? To find out which format (file system) your storage device is using: Select the device in the Finder. Choose File > Get Info, or press Command (⌘)-I. Check the Format shown in the Get Info window. Or use the  System Information  app: Select Storage in the sidebar, then check the File System column for your volume. Which format should you choose? When you install macOS High Sierra on the Mac volume of a solid-state drive (SSD) or other all-flash storage device, that volume is automatically converted to APFS.  Fusion Drives , traditional hard disk drives (HDDs), and non-Mac volumes aren't converted. Disk Utility in macOS High Sierra can format most storage devices using either file system. ...

To use Profile Manager as a mobile device management (MDM) service, Server should have a static Internet network address, and a fully qualified domain name, and it can’t be on an isolated network. Devices communicate with the server to obtain configuration profiles over the network. After a device is enrolled with the service, it’s called a managed device . You can: Update its configuration Query its status Lock and wipe the device Clear the passcode on iOS devices Open the Server app, click Profile Manager, then click the Configure button next to Device Management. If prompted to enable Open Directory, complete the setup assistant. Select the SSL certificate to use to encrypt data between Profile Manager and users’ devices. You can use the existing self-signed certificate. If you already configured your server with another certificate, you can select it now. Enter an Apple ID to enable Apple Push Notification service.

Ports used by Profile Manager in macOS Server Profile Manager uses certain ports for device enrollment and management.  To use Profile Manager, you should make sure that the following ports are open on your network. Port Incoming or Outgoing TCP/UDP Description 2195, 2196 Outgoing TCP Used by Profile Manager to send push notifications 5223 Outgoing TCP Used to maintain a persistent connection to APNs and receive push notifications 443 Incoming TCP Provides access to the web interface for Profile Manager admin and user portals 80 Incoming TCP Enrollment access to the Certificate Authority via SCEP macOS Server 5.3 and later 1640 Incoming TCP Enrollment access to the Certificate Authority via SCEP in versions of macOS Server prior to 5.3

You can replace the default self-signed certificate for servermgrd with a signed certificate using Keychain Access. When you assign a trusted signed certificate to servermgrd and remotely connect to your server, the certificate warning no longer displays. Import your certificate identity using the Server app. For information about importing a certificate, see Import a certificate identity . Open the Keychain Access app (located in /Applications/Utilities/). If keychains are hidden, choose View > Show Keychains. In the search field (located in the top-right corner), enter com.apple.servermgrd. Double-click the com.apple.servermgrd (identity preference) system keychain. Click the Preferred Certificate pop-up menu, and choose the imported trusted certificate. Click Save Changes. If prompted, enter your user name and password, then click Modify Keychain.

While Identity Finder is distributed from the IdentityFinder.com website as a dmg, modification to the dmg or application bundle contained therein is not supported.  Any organization using the Mac client must create and deploy a custom Installer Package that can include a custom xml file, license file, and other supplementary files as well as configure the endpoint service application. The only supported method for creating a custom Installer Package is to use the Identity Finder Client Custom PKG Builder (PKGBuilder) application referenced by and attached to this article.  This application uses pkgbuild, productbuild, and productsign, which are all included with Mac OS. Note : Mac clients prior to version 8 cannot read the package format created by this tool. Therefore: Packages created with this tool can be used for new installations of version 8 of the Mac client. Packages created with this tool can be used for manual upgrades of any version of existing client inst...
