Comcast will many times install to a single PC and use the MAC of the PC NIC and limit you on the network to only that MAC address. Not always, its weird. Then you want to add devices and a wifi router and you have to spoof the address. I think a lot of people want to do it at the laptop layer so the MAC is protected whereever they roam.
Scandalous reasons? Better security, the right to anonymity, I dont know but the script is very useful and appreciated. The MAC address of intel NICs can be changed permanently with 'ethtool' under linux.
I used this command line utility to change the PCI IDs of intel NICs, so they'll be recognized in macOS without the need to patch KEXTs. I never used it to manipulate the MAC address though. This should work: again: intel NICs only AFAIK and to be clear: this changes the MAC address in the EEPROM of the card, so this is really permanent!

My NIC is intel X520-DA2 with dual ports with Intel MAC address, since mac pro have dual ethernet ports with different MAC address, i want assign it to my new intel NIC. Question: Is possible to apply Intel NIC with dual ports to assign different MAC address individually?
Can you assist how looks command to assign MAC address separately each port? Thanks in advance. Edit: just my guess, is this command possible? I'm using generated random MAC address with apple prefix for example.
I have an external hard disk with two partitions on it: a principal partition is used for all my stuff (apps, games, user file, music, etc.), and a secondary partition with a minimal OS X installation, containing some diagnostic and recovering software utility, that I periodically use for backup and testing purposes. The principal partition is obviously always active, but ideally the secondary partition would be inactive or hidden on boot, so that it no longer appears on my desktop and would be manually actived when needed (with Disk Utility, the command line or via a automated backup script). For example, I know that TechTool Pro does something similar and calls such partition 'eDrive.' There are several hints on this site for unmounting a partition at login, but a better way to make this happen can be used. You need to create an entry point in your filesystem table to tell the OS not to mount that specific volume, and this is relatively easy.
In Mac OS X, and under Linux and others unix systems, the volume mounting configuration file is located in /etc/fstab. This file in Mac OS X Tiger is empty (in Panther, it's commented), but type man fstab in Terminal to read some important information. Read on for my solution.
An /etc/fstab example: # Identifier, mount point, fs type, options1 UUID=DF000C7E-AE0C-3B15-B730-DFD2EF15CB91 /export ufs ro UUID=FAB060E9-79F7-33FF-BE85-E1D3ABD3EDEA none hfs rw,noauto LABEL=This40Is40The40Volume40Name none msdos roThe Identifier is used to identify the volume; the LABEL is the volume name, the UUID is the Universal Unique Identifier Drive. You can use both, but the UUID is the best choice because renaming the volume will not change this identifier. The mount point is the directory used when the volume is mounted; set none to use the pre-defined OS X directory, i.e./Volumes/ The fs type describes the type of the filesystem; use hfs for a Mac volume. The field options describes the mount options associated with the filesystem. The option auto will mount the volume in the normal way, noauto will force the volume not to be mounted automatically; and last, use rw or ro for a read-write or read-only disk.
The UUID of a volume can be seen in Disk Utility (click the Info button and find the Universal Unique Identifier), or in Terminal using this command: diskutil info /path/to/diskIn Mac OS X Panther, Disk Utility and the diskutil command doesn't display the UUID value. But if you look in the system.log file, when the disk is mounted, you can see something similar to this (line breaks added for narrower display). Localhost diskarbitrationd87: disk1s9 hfs 77F3E84D-E0ED-3194-96A5-BED10893FFF4 FireWire HD /Volumes/FireWire HD. Localhost diskarbitrationd87: disk1s10 hfs F0E430C1-5558-3BB3-9FA9-6904B663FEEA Mac OS X Disc /Volumes/Mac OS X DiscThe string before the volume name is the UUID for the disk. Now that you have a UUID for the volume to hide during the mount process, from an admin account edit your /etc/fstab file: sudo pico /etc/fstab/Add a line with the UUID for your volume and the mounting point information, for example: UUID=F0E430C1-5558-3BB3-9FA9-6904B663FEEA none hfs rw,noautoSave the file and reboot (for internal drives) or unmount, disconnect and reconnect the volume (for external drives).
Now the system should not mount the partition identified in fstab. You can still manually mount the volume in Disk Utility, or via the command line (and for a volume containing a boot system, rebooting from it). robg adds: I haven't tested this one, and would recommend having a good backup before proceeding if you're going to do so.
This is a great hint, it's finally showed me how to do the opposite of what you were trying to do. I've been trying to figure out how to get external Firewire drives to mount even if no one is logged in to the Mac. I just grabbed all the UUIDs from my various drives and made entries like UUID=922AD32A-308F-332B-876D-57C5F9CE2EDD none hfs rw,autoUUID=2D38EBA3-0776-33AB-87CB-AFCE63BBFE44 none hfs rw,autoUUID=E2C8C41F-5F51-3DC7-AE05-4A15AE853A45 none hfs rw,autoUUID=CC346AF2-DCAD-31DC-B01C-B58996BADC25 none hfs rw,autoone per partition. They all mounted just fine. The first is an entire 250 GB drive, the other three are all partitions of a second 250 GB drive. You'll give yourself a helluva fright if you do - on my setup 10.4.8 Drive Genius unmounts the disk, sure, but macos immediately tries to remount it, can't read the format and asks if you want to initialise it.
Every time you start up. Plus diskutility can't mount the partition, also seeing it as unformatted - and the whole point of this exercise is to have the disk easily to hand, just not using resources I'm on a G4 windtunnel with 3 extra drives, and this little trick saves me about 30dB my 2p. Hey, this is a great tip. Despite my lack of Terminal experience, it works on my Mac Pro on 10.4.8.
Rc.local For Mac Pro
However, for other Terminal newbies I want to pass on what I learned. I echo the comment about the fact that the fstab file does not exist and is created when you sudo pico and save the file with the line in it.
There is also a file in etc called fstab.hd, but that isn't the file you're looking for. Don't edit that one. No other lines in the fstab files are needed. Just the ones starting with the UUIDs of the drive you want to prevent automount on. At first I did not see the UUID in Disk Utility, and figured out that you have to get info on the volume, not on the disk mechanism. You can then copy the UUID from Disk Utility and paste it into Terminal.
Don't forget to add 'UUID=' before it. Thanks for the tip, I really needed it for a machine where I wanted to keep a certain volume offline when booted into the test OS. I have a 'SanDisk Cruzer' USB memory stick, which contains two filesystems: the normal read/write filesystem, and a read-only ISO-9660 filesystem containing useless Windows software. The second filesystem appeared as a CD-ROM icon! Both partitions needed to be unmounted (or ejected) before unplugging the USB stick to avoid an error message, although no harm could come of not ejecting the ISO-9660 filesystem. It was just a nuisance. However, this hint showed how to avoid it being mounted at all.
There was no UUID, so I used the volume name ('U3 System' in my case) and created a one-line /etc/fstab file containing: LABEL=U3 040System none cd9660 ro,noautoNote that the space in the volume name needs to be given in octal. I figured it out. Step by step it goes like this: Open console, click on system.log, type 'localhost diskarbitrationd' into the filter window, stretch the window the full width of your screen and you can copy the UUID of the disk you don't want to mount. Open TextEdit and paste it there. Now open Terminal and enter 'sudo pico /etc/fstab' then hit enter, enter your administrator password, now, go back to TextEdit and copy paste the following: 'UUID='the UUID you copied from console' none hfs rw,noauto' and then cut and copy your UUID into the location between the quotes, of course leave out all of the quotes, then copy the whole string (mine looked like this: 'UUID=09BFBF06-7E2F-3364-B851693 none hfs rw,noauto', then paste it into Terminal and hit enter.
Next, type cntrl 'O' (the letter O not the zero) then just hit the enter key and it should save the newly created fstab file in your /private/etc/directory. Next, restart and the partition will not appear on the desktop but will be accessible with disk utility.
Works like a charm. I'm using OS 10.4.10. Hope this helps some newbie like myself. This is handy now that many stick drives have a 'U3 System' partition, which is useless for Mac users (next time I buy a thumb drive, I'll just erase the whole thing right off, but it's too late for that this time) since the disk I want to disable mounting of is on a stick drive, I expect to be going from computer to computer (so a /etc/-based solution isn't ideal), and using computers where I'm not admin (so a /etc/-based solution isn't an option).
Is there a way to automatically, invisibly run a script when a drive mounts, as a sort of 'mount items'? I could have something like diskutil unmount (me) run from a file on the disk, triggered by the disk itself. (If this is even possible, the script might have to be on the partition I'm keeping mounted?). Hi, I have tried those suggestions previous to last one posted. Being that I'm in Lion, I think that's why they didn't work. I have 2 questions: 1-From those attempts, there were created 3 files in 'etc' folder: fstab.save, fstab.save.1, and fstab.save.2 Will it be safe to delete those files being that they only contain what I wrote in my 3 attempts?
-UUID=E095D3F5-F170-3D34-8A52-7DD6EB5530E2 -UUID=E095D3F5-F170-3D34-8A52-7DD6EB5530E2 none hfs rw,noauto -UUID=E095D3F5-F170-3D34-8A52-7DD6EB5530E2 none ntfs ro,noauto 0 0. If I create a new file fstab in the folder 'private' and no in 'private/etc' as per last update (UUID=XXX-XXX-XXX-XXX-XXX none hfs rw,no auto), 2-Will the command work to avoid an iPod to mount when I start the machine? Thank you. I just tried this on 10.7.3 and it worked. A few updates:. the UUID can be found in Disk Utility (File Get Info on a volume). the UUID can also be found using diskutil info /Volumes/yourVolumeName in Terminal.
the preferred way to edit /etc/fstab is now by using the command sudo vifs, but that means you have to edit using Vim. Vim can be learned by typing the command vimtutor.
I just used sudo nano /etc/fstab because I didn't know at the time. I also noted that this can be used to change the mount point of the volume. I have an external 2.5' drive that I use for my iTunes folder, but I also have a partition with a copy of the OS X installer, as well as one with DiskWarrior on it. I used the hint to hide the two boot volumes, but I also set the largest partition to mount as the iTunes folder in my home folder, so the entry looked something like this: UUID=myPartitionsUUID /Users/me/Music/iTunes hfs rw,autoNow, when I plug in the drive, the boot partitions don't mount, and the other one mounts in place of the default iTunes folder.
Some notes:. If you customize the mount point, make sure that the destination folder already exists. If it doesn't, it won't mount, and Disk Utility will claim that there's something wrong with the drive. In other words, if your mount point is /Users/you/Music/someSubFolder, make sure that someSubFolder already exists. If your customized mount folder already has stuff in it, you will lose access to that stuff while the volume is mounted.
When it is unmounted, the regular folder's contents will return. Strangely, the iTunes partition also mounts at the 'Computer' level, though it does not in /Volumes. I don't know why. Also strange: I can't rename the partition in the Finder once I've added the entry in fstab. That is, if your partition is named 'Seagate', when it mounts, the iTunes folder will disappear and be replaced by an icon named 'Seagate', with whatever icon the partition has. If you try to rename it to iTunes, the change won't take.
Unmount the drive, comment out ( #) the appropriate line in fstab, mount the drive, change the name, unmount, remove the comment character in fstab & save, remount, and it should appear with your desired volume name. I have no idea whether anything I've suggested here is monumentally stupid and may destroy everything you hold dear. If someone does know, I would appreciate being enlightened.
