dev/disk7 on /private/var/folders (hfs, local, union, nobrowse) dev/disk6 on /private/var/db (hfs, local, union, nobrowse) dev/disk5 on /System/Installation (hfs, local, union, nobrowse) dev/disk4 on /private/var/run (hfs, local, union, nobrowse) dev/disk3 on /private/var/tmp (hfs, local, union, nobrowse) dev/disk2 on /Volumes (hfs, local, union, nobrowse) dev/disk1s3 on / (hfs, local, read-only) Running the mount command in recovery mode is informative: $ mount So that's disk0 and disk1 what about the rest? I'm not certain, but I'm pretty sure they are RAM disks to save temporary data in folders OS X modifies as it runs (remember that in recovery mode, you're running from a read-only disk image). BaseSystem.dmg has a volume named "Mac OS X Base System". You've got /dev/disk1s3 named "Recovery HD", but for some reason it's mounted as "/Volumes/Image Volume" in recovery mode. Actually, BaseSystem.dmg is compressed down to only 451MB (at least in OS X v10.7.0).Īlso, the volume naming is somewhat inconsistent.

Notice that the Recovery HD is only 650MB, but Mac OS X Base System is 1.4GB? That's because it's a compressed disk image (and I'm pretty sure that compression is the reason they bother with all this disk image trickery). The booter mounts this volume (it attaches as /dev/disk1), and transfers to OS X running on it. It contains minimal booter files and kernel, and at //BaseSystem.dmg, a disk image with a stripped-down and tweaked copy of OS X. Recovery HD is marked in the partition table with the type Apple_Boot, but is actually in the normal HFS+ format. And some other details are different, but actually not that much.)

And in addition to Macintosh HD and Recovery, there'll probably be Preboot and VM volumes, and starting in Catalina there'll be a separate "Macintosh HD - Data" volume holding the user-modifiable parts of the main filesystem. (Update: with newer versions of macOS running from an APFS volume, there'll instead be a single APFS "container" on the disk the volumes under it will be listed separately under a "synthesized" device, probably /dev/disk2. Let me start at the beginning: your hard drive (/dev/disk0) has two relevant partitions: Macintosh HD (your regular startup volume), and Recovery HD. Just remember to switch network locations if you start using a different network - others may not take kindly to you using a static IP address on their network.It's rather complicated, and actually a lot of the complexity is to avoid wasting space I don't think you can "reclaim" anything without breaking it. Now the other devices on the private network can access your Mac by using the static IP address you assigned it. In this example, I could have picked any address between 192.168.7.0 and 192.168.7.255, as long as the address was not already assigned to another device.Ĭongratulations! You have successfully set a static IP address for your Mac. What number should you enter? One method is to take your current IP address and change the last part of the number. The window shown below appears.įrom the Configure IPv4 menu, select Manually.Įnter a static IP address in the IPv4 Address field. You’ll need to select a new IP address from within the private IP address range listed. Make a note of the current IP address assigned to your Mac. In this example, I’m connected to a wireless network, so I’ll select Wi-Fi. The window shown below appears.įrom the sidebar, select an active network interface.

See How to Configure Network Locations in OS X for instructions.įrom the Apple menu, select System Preferences. This will allow you to use the static IP address for certain networks and not others. If you own a MacBook, you may want to create a new network location.

Here’s how to set a static IP address in macOS:

Tip: You may also need to change your router’s settings to assign your Mac a static IP address and configure port forwarding. Other devices connected to the local network will be able to access your Mac, and if you set up port forwarding, certain services running on your Mac will be accessible to the outside world. For those unique situations and others, only a static IP address will work.īy setting a static IP address in macOS, you’ll create a permanent, private IP address for your Mac that won’t change from one day to the next. But dynamic IP addresses won’t work for certain tasks like port forwarding, dynamic DNS, or client-to-client file sharing on the local network. (To check, see How to Find Your Mac’s IP Address.) That’s not a problem for the majority of users - most people don’t care whether their IP addresses changes or not. When your Mac is connected to a private network in a home or office, it’s probably assigned what’s known as a dynamic IP address.
