I’ve created a thumbdrive with 12 partitions with ASD EFI tests for Macs.  I tried renaming the partitions to shorter names with both Finder and Disk utility (so they show up in startup manager properly, the instead appear with this "EFI BOOT" name, see picture).  The problem is that the names of the partitions in Startup Manager is different to the one I put.  I also tried renaming them with this command (to no avail): /usr/sbin/diskutil rename ASDEFI124 42 (where 42 is the new name I want to set)  I also remember that in older versions of macOS, such as Yosemite or earlier, when you restored the image in disk utility, it gave you the option to set a name for the new partition and that seemed to work.  But I can see this is not offered in macOS 10.11 nor in macOS 10.14.  Any way to rename them to this shorter names?  I'd like shorter names here, like 40 41, 43...

I am trying to rename my Windows / Boot Camp partition from "EFI Boot" to "Boot Camp" or "Windows". But I do not figure out where to rename.   I tried bless command on the NTFS Volume, I tried creating the folders "System/Library/CoreServices" and copied the .disklabel file into it (or also blessit) but nothing changed.  Finally I got the Volume Icon on Boot Selection to work by copying the icns File onto the EFI partition. Also tried blesson the EFI partition – but this also do not work.  So I have my Icon, but I also would like to rename it – how can I do this?  Systems are Windows 10 and macOS Mojave.

I have a MacBook with 1TB SSD. I want to have two separate partitions with two independent macOS installations. I want to make sure that none of the partitions have any kind of possibility to interact with the other, I want them to be as separated as if they were physically separate. Is this achievable with, for example, FileVault for each of them? Edit: My question is neither &quot;how can I install two different macOS versions on two different partitions on one SDD&quot;, neither &quot;how do I use FileVault&quot;, etc. I know how to do all of that. I want to make sure that there is no interaction between the partitions possible. Can this be made sure with the above approach? Is it sufficient?

So I tried to fresh install macOS, pressing command ⌘-R when starting the Mac to enter Recovery Mode. But only the Windows partition (120 GB) is showing to reinstall macOS on instead of the original 350 GB partition. I reinstalled macOS on the 120 GB partition. Now I don't know how to retrieve my files back from the old 350 GB partition. They all are in same disk. Linux is not booting now too.

Actually I want to dinamically assign bootfile-name based on clients MAC.  I have tried this config:  option bootfile-name concat( binary-to-ascii(16, 8, "", substring (hardware, 1, 6)), ".cfg");   But this is wrong config (as dhcp server isn't starting at all). If instead of concat(...) I put just real filename (e.g. "000102030405.cfg") everything is ok. But this is not what I need. Is there any way to dynamically set bootfile-name?

So I am attempting to create a Windows 10 install USB on my MBP running macOS 10.14 Mojave. To create a bootable USB it needs to be formatted into FAT32, not exFAT. The issue is that when copying the .iso to the USB it fails because the file sources/install.wim is 4.4GB. I can't format as exFAT because I cannot boot from that format and I cannot use FAT32 because of the 4.4GB file. I used the command cp -rpv /Volumes/CCCOMA_X64FRE_EN-US_DV9/* /Volumes/WINDOWS10/ after Boot Camp Assistant failed to create the  USB with a "Drive too small" error, even though it was a 16GB drive. When I wasn't paying attention, the cp completed and the installer booted, but failed with a missing: sources/install.wim error because the file can't be copied.  Is there any solution to this problem, or should I just burn a DVD with the installer on it?  EDIT: I forgot to specify that I was creating a USB for a PC, not a Mac. The Mac was just being used to create an install USB.  Heres the file:

I'm playing around with fdisk and I tried to create a partition on an empty USB drive. Here's how that went: Command (m for help): n Partition number (1-128, default 1): 1 First sector (34-61187102, default 2048): 2048 Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-61187102, default 61187102): +30000000           Created a new partition 1 of type 'Linux filesystem' and of size 14,3 GiB.  so just one partition with 30 million sectors. However, when I check how many sectors it contains I get:  I'm checking with a different program and I see again that additional sector:  Sorry for the pettiness :) I'm learning.

When clicking continue on the first Boot Camp screen,  I am presented with a dialog that displays:     The startup disk does not have enough space to be partitioned.   You must have at least 39 GB of free space available.     This is despite "About this Mac" reporting 271GB of free space:    And "Disk Utility" reporting 268GB of free space:    Searching online I found  which suggested it was the result of Time Machine which i recently enabled and suggests to run sudo tmutil thinlocalsnapshots / 999999999999 which I did, it ran sucessfully, and I restarted, yet to no avail.  What is the solution to this instance of Apple's poor engineering?  Running macOS High Sierra 10.13.4 (17E202)

Recently I changed my partition scheme from MBR to GPT, and during after conversion I saw a another partition named EFI ... I don't have a good idea what does it do or its purpose ... but I think it's use for backup's.  So my question here is can you explain/tell me about EFI and it purpose?

No, this ain't a duplicate of , as this explains how to restore eth0 naming, but not how to individually name a specific interface.  I don't want to assign based on MAC match. All I need is to assign name based on the USB path.  When I plug in an USB network adapter, on Ubuntu 17.04 it gets assigned a network interface name based on its MAC, such as encx000000000000. Now I would like to rename it to something more telling, based on its ID_PATH=pci-000:02:03.0-usb-0:1:1.0. In particular, I don't want to match based on MAC address. The rationale is that after interface replacement all would break down, but if someone simply replaces network interface hardware so that the new hardware is in the same place as the old one, the system will tuck on without needing IT and reconfiguration support.  So I created a file /etc/systemd/network/50-my-island.link:  [Match] Path=pci-000:02:03.0-usb-0:1:1.0 [Link] Name=island0   Unfortunately, the name is never assigned. Using udevadm info I can see that there is ID_NET_NAME=island0 set, but it does not apply. Trying NamePolicy= or NamePolicy=name under the [Link] section doesn't help either.  I'm lost! How can I assign my name in the .link file to my USB network adapter? Is this possible at all without resorting to some udev rule? Why then having .link files at all when they don't seem to work in my case? Where did I make an error?

Been running El Capitan since it was officially released. Updated to 10.11.4 a few days ago. I have a WD Elements USB 3.0 drive connected to my Mac mini (directly to the rear ports, not via a hub). Ever since the update to 10.11.4 whenever my Mac goes to sleep and I wake it up again, I get a notification to say the "Disk was not ejected properly".  This has never happened with this drive before, not on Mountain Lion, Mavericks, Yosemite or El Capitan until now.  I have another external caddy also with a full size 3.5" drive in it. This is powered by the mains.  It seems to me that the Mac is now terminating power to the USB 3.0 port prematurely (before the disk has had a chance to unmount properly ?), I do not get the message for my full-size disk that is permanently powered.  Tried adding the disk to the spotlight ignore list but to no avail.  Anyone else notices this issue?

How exactly would I rename a USB drive?  I've read that you can go into the Disk Utility, click on Edit Partition, and there is an option to rename the label but I can't click in the area to rename.  Is there any other way?

I have an external HD which used to be my TimeMachine drive. I got a different drive for that, so I want the original drive back as an external on my Windows box, but it has this random 200 MB partition labeled as EFI System Partition. How do I get rid of this?

I know I can set the volume name when I format the partition with the -n option of mkfs.vfat. But how to just change the name without formatting?  I especially want to be able to use lower and uppercase letters. In worst case, I can use a windows tool, but windows by default transforms all letters to uppercase (but works fine with lowercase letters in volumes created with mkfs.vfat).

I'm new to Mac usage.  It seems that most commands trip over options given after the file names. In linux, which I've used for years, it doesn't matter.  On Apple, it does.  Is there some setting somewhere or some hack to make commands like ls behave "normal"?  dwilson 0====&gt; ls -l p* -rw-r--r--@ 1 dwilson  owner  184 Jul 29 13:57 poo.c -rw-r--r--@ 1 dwilson  owner  133 Jul 29 13:57 poo.h  dwilson 0====&gt; ls p* -l ls: -l: No such file or directory poo.c        poo.h  dwilson 1====&gt;

I am attempting to clone multiple partitions with either  or dd without cloning the whole drive which consists of:  A boot partition A home partition  Seen below is the original installation on a 128GB SSD, which I successfully cloned to a larger 250GB. This as a backup that I would later try to resize and shrink down.  Below is a photo of a working clone of the operating system, which is now about 41 gigs in size total after being resized with Gparted.  I have tried to clone these partitions to my 64GB USB disk as a working portable backup, but have ran into some issues. I have tried using: sudo -s dd if=/dev/sdb of=/dev/sdc &amp; pid=$! while kill -USR1 $pid; do sleep 1; done  This bit for bit cloning method tried to copy the unallocated space on the input drive, which obviously won't work because the output disk is much smaller. In a second attempt I was able create a partition table on the destination disk that matched the source's sizes. I then tried to use boot repair and got  Moving onto to  options; normally a disk to disk would be my choice, but since the destination drive is smaller than the source,  will not allow this. I do see an option to copy ONE partition at a time using the disk to disk option, but do not see how I might clone all three at once. I know there is an option to do this with saving as image but I want the USB to be bootable. One way I can think of making this work would be to make an image of the partitions I want to clone using disk to image, then restoring the image to the 64GB USB disk later, but after trying this I ran into more errors. After making an image of /dev/sdb/ I attempted to restore the file but got this error about /dev/sdb2/ missing:  (/dev/sdb is the target for this session) So perhaps my image was OK, but it didn't properly read /dev/sdb2/ so I checked it with Gparted again and saw this following here:  I checked with Synaptic Package Manager to see, and I already have e2fsprogs v1.42.9-3 installed. So I did some reading and tried the following solutions that have worked for other people: sudo fsck.ext4 -f /dev/sda6 sudo touch /forcefsck Sudo reboot  this seemed to work temporarily, as after another reboot or two, the problem still persists. I am assuming now that during the device to image process in Clonezilla that my /dev/sd2/ was not read properly, as I can not even access this partition in Nautilus or Gparted. I am thinking that is may have been caused by the re-sizing of the drive, but can not be sure, as it will still allow me to boot to this installation. I think I can actually clone these two partitions to image, and then restore them but I need to address this problem of:  The following list of software packages is required for ext4 file system support: e2fsprogs v1.41+.  Could this have come from re-sizing the partition? If so, how come I am able to boot to this installation if it can't be read?

In Finder when I type something in the textbox the default is to search the whole mac in the contents of the files. I was able to change the default to search the current directory, but didn't see an option to change search for contents to search for file name. How can that be changed?
