Netboot verbose mode?

I'm trying to troubleshoot the netboot process on my macbook. I'd like to see something other than the flashing globe symbol when it is trying to netboot. Does anyone know how to get a "verbose" netboot mode? Holding cmd-v and n during boot just skips the netboot process entirely...

Take a look at Mike Bombich's troubleshooting page:

Hope it helps.

10.6 Verbose mode stops at ACPI_SMC_PlatformPlugin::start....

Macbook not booting and stalls at spinning gear.
Tried many things but ended up booting into verbose mode and it stops at
ACPI_SMC_PlatformPlugin::start - watiForService(resourceMattching(AppleIntelCPUPowerManagement) timed out.
Previously in the boot, it says it failed to load that kext because the link failed.
- Tried repairing permissions
- Netbooting into AST and running MRI. No errors. Reset SMC and NVRAM. No change.
- Swapped RAM
- Made image and restored to a new hard drive. Same problems.
- Booted different computer from the harddrive. Still get spinning gear.
- Swapped hard drive for a working one from another laptop and it booted fine.
Any thoughts before I wipe the HD it and start from scratch?

Dont wipe the hard drive!
Just had this problem on a macbook pro 2011 at my work (computer repair business). The problem occurred after switching out the hard drive and hard drive cable. Tried booting an Apple Hardware Test, by install disk, or by bootable USB OSx. Each time the verbose popped up before completing boot and ended at a failure of the load of the driver regarding cpu power management.
Ultimately, the problem was a corruption of the firmware, which is embedded in flash-based rom chips on the logic board. The Apple website has the firmware for your model available and it should boot from the disk without trouble.
Incidentally, all attempts to boot failed except when booting to the OSx Lion full install from USB. This alone seemed to bypass the corruption. Regardless, the firmware restore should do it.
So don't wipe your drive.

SSRS error - verbose mode

We have a SCCM and use SQL 2012 server for reporting. Recently we have started experiencing a problem where we can browse to the reports and once we do run the reports, it tries to run forever and eventually halts with the following error
An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError)
I have enabled verbose mode on the sql server and restarted the reporting service. Below is the log file where I am hoping someone will be able to tell me what the issue is:

This was to do with NIC settings on the SQL server. There was a mis-configuration where data was taking long time to copy. Once we have corrected this, all started to work just fine.

HELP! MacMini starting up in Verbose Mode

Hi,
My Mac Mini seems to be sarting up in Verbose Mode (black background with white type). Any ideas why this is happening? and how do I stop it?
I've run Disk First Aid off the installion CD and its fixed all the problems that it found, but it still happening. Do I need to wipe the HD and start all over again, or try to just re-install the OS?
Any words of wisdom?
Thanks!
Su
Mac Mini Mac OS X (10.4.9)

also download and install onyx
http://www.titanium.free.fr/pgs2/english/download.html
once installed, open onyx and go to the parameters tab, then go to the tab under that named login. find the one that says startup mode. select normal mode and it should reset it to normal.
hope this helps

Suddenly, Macbook doesn't boot up in single user mode or verbose mode

Hello, I use the single-user boot up quite often to check permissions and do a fsck after my mac crashes.
I do this by pressing Apple(Command)-S at startup or cmd-V for the verbose mode. I do this all the time.
But now my Mac won't take it anymore. It just refuses to accept any key combo. Any ideas why this is happening?
thanks.

Hi Jose, actually you don't have to boot to single user and repair permission all the time. Just perform that after you update your software and or hardware.
Can you start up normally and then use your keyboard as usual, or is the keyboard refuse to do so?
Try to reset your PRAM and or PMU to refresh your hardware behavior.

IMac won't boot up. Stuck in "verbose mode" ??

I've had this problem on and off for a few weeks now. I either restart my iMac after installing some new software-or for other reason- and my computer won't boot up. Sometimes it will stay at the white screen with the grey apple for hours if I leave it there. I've tried all the tricks with key commands. I even reinstalled my software, which worked, but now its happening again. Today, I restarted my iMac, and the same thing is happening, except sometimes it will go into what I've heard called- "verbose mode." The screen is black and white command text appears in the upper left hand corner. Here are some examples of what appears...
No Airport driver found.
Exited abnormally. Bad system call.
Repawning too quickly! throttling
10 more failures without living at least 60 seconds will cause job removal.
Will restart in 10 seconds.
(this will continue until it has restarted and failed 10 times. After this is done, it will display one of the following...)
too many failures in succesion
OR
local:/root# (continuously flashes on the screen)
OR
localhost:/ I have no name!# AppleYukon- eno link active, 100-Mbit, full duplex, flow control disabled.
I really don't know what to do. I'm really frustrated with my iMac. I've had to replaced a dead hard drive within the 6 months of my purchase, and now it is acting crappy again.
Can anyone help?
Thanks.

I tried using the disk utility on the grey disks, but
they can't repair the error on my HD. I can't restore
the original software from the disks either... there
is an error when I try.
No, you can't restore while the current OS is in place, due to the fact that your 10.4.8 isn't compatible with the older version (10.4.4) that's on the install DVDs. Once a Mac OS is in place, it can only be upgraded, not downgraded. You'll have to choose either:
to "Archive & Install" which would set aside your current system unerased until the new installation is completed and your current settings are transferred over - at which point you can erase the archived OS.
to entirely erase and reformat the HDD, then install a fresh OS.
Use the install disc's version of Disk Utility to perform either. First, though, you probably need to do a PRAM reset - that often clears things up so that you won't get an error message.
To reset the PRAM:
1. Shut down the computer.
2. Locate the following four keys on the keyboard: Command (Apple logo), option, P, and R. You will need to hold these four keys down simultaneously in step 4.
3. Start up the computer.
4. Press and hold the Command-option-P-R keys. You must press this key combination after the startup chord sounds, but before the gray screen appears.
5. Hold all four keys down until the computer restarts and you hear the startup chord for the second time.
6. Release the keys.

Freezing at startup - weird message when starting up in verbose mode

My macbook pro, only about 2 months old, freezes a lot while its starting up. i have to keep turning it off and on for it to work. It gets stuck at the grey screen with the apple and the loading icon.
I decided to start up in verbose mode and maybe i can see what the problem is. So i did just that and i got this error message:
SATA WARNING: completing a zero block transfer.
it keeps repeating that message and scrolling down the screen forever.
I have no idea what that could be.

Most likely a problem with the disk and/or some corruption of the directory. Be sure to back up your own data if you haven't done so already. Then boot from your install disk and go to the menu bar and select Disk Utility and then Repair Disk. If it reports a problem and fixes it, run it again until everything comes up clean. If it reports a problem it can't fix you could invest in DiskWarrior, or, if you have AppleCare I believe you got a free copy of TechTool, you could try running that.

How to permanently boot up in verbose mode?

Hi,
I want to always boot up OS X Mavericks (10.9.2) in verbose mode (debug mode) as I pressed Cmd+V everytime.
I remember an old command which I used on Snow Leopard for doing this:
« sudo nvram boot-args="-v" »
but I don't know if it's still valid on Mavericks!!
The command « nvram -p » works and doesn't show any "-v" verbalization in the "boot-args" section, so I'm currently thinking my command is still valid (it does still show other commands, though).
But I need your help, Apple experts! Can you confirm this?
Thanks in advance,

Restart the computer. At the chime press and hold down the SHIFT key until you see the spinning gear below the Apple Logo. You should also see a progress bar appear. Booting into Safe Mode takes much longer than a normal startup.

TS2570 iMac won't boot, GSOD with Flashing Question Mark, safe/verbose mode not possible

I have an iMac 24", just over 2 years old running OS X v10.5 (Leopard). Mighty Mouse and bluetooth keyboard, no peripherals.
It slowed enormously over the last few weeks and has now ceased to boot.
On switching on I hear the chime (blank grey screen initially), the grey screen hangs for approx 30sec before the flashing folder/?mark icon appears.
There is no further progress.
Boot key combination results:
Can reset NVRAM (Option-Command-P-R)
Cannot boot to safe mode
Cannot boot to startup manager
Cannot boot to verbose mode
Cannot boot from target media (DVD etc)
Cannot boot to AHT mode
Cannot boot to single user mode
I have followed the steps here http://support.apple.com/kb/TS2570
Disconnect, test peripheral devices and network cables - done - de-powered and rebooted. No difference.
Perform a Safe Boot- this does not work. I am familiar with the boot combinations and timings. The safe boot leads to the same flashing folder/?mark icon. I have also tried verbose, single user, AHT and startup manager with the same result.
Reset the NVRAM / PRAM - done - this worked and kicks the system into an auto-reboot after 3-5 seconds. This also demonstrates the Keyboard is fine. The subsequent boot fails at the same point via normal, safe or verbose boot instructions.
Start from your Mac OS X Install disc; use Disk Utility – I never received an OSX install disk. I have the original box with receipts etc, the only disk present is an unsealed version of iLife (yeah thanks Apple). Where would I get one?
Check your cables and power source – done - all fine.
Remove third-party RAM and internal hardware – not applicable.
Perform an Archive and Install installation of Mac OS X – how would I do this when I cannot boot the device?
Perform an Erase and Install installation of Mac OS X as a last resort – how would I do this when I cannot boot the device?
To me the problem looks like a HDD failure. I had windows (dual boot) professionally installed when I bought the iMac and since the Windows boot option is also not visible (startup manager itself does not work) I suspect the system can’t find bootable media because the HDD isn’t spinning.
An OS corruption would generally affect one or the other but presumably not both Operating Systems simultaneously.
It's hard to be certain, but I’m sure it used to make more noise.
I had a look into opening it up and troubleshooting the physical components but it’s hard to know where to start. There are no obvious ways in and I’m not a professional so decided to post a question here rather than hack it open.
I'd be grateful if you could suggest next steps here, or is it time to go dig a hole in the garden? I certainly expected more than 2yrs life from a £1200 unit.
Many Thanks,
Ryan

Thanks for the response,
I bought the iMac new, 17th Jan 2010, all receipts intact but no extended warrenty. I declined the Applecare Plan for two reasons.
(1) The sales rep seemed very confident in the product build. In fact the main justification of the price tag was the quality of the device. I'd also never had an apple device malfunction at that stage.
(2) The incumbent EU regulations are quite fair in so much as legislation dictates electrical goods should be manufactured to function for a 'reasonable' lifetime. I would be morally uncomfortable paying for rights I theoretically already have.
I triple checked on the OS X disks you mentioned but no joy. Unusual as it may be, the box has not been used and it's contents reflect the day of purchase.
I'm happy to order the OS X v10.5 DVD and attempt a boot to the disk utility, I don't mind risking a few bucks on a potential fix. I'll need to figure out where to order the disk, the call centre is closed ATM so watch this space.
What I'd really be interested in is; (a) is there a known diagnostic routine to determine the HDD functionality and (b) it is possible to replace/upgrade the HDD? This for me is where the iMac loses ground against a conventional PC in terms of motherboard/component access. It's far superior from an asthaetics perspective while things are running smoothly and the OS is great but the first sign of a hardware malfunction and there seems little or no scope to self-medicate the device.
The disk has around 40-60 GB free space.
I don't have a second Mac, nor any friends or family with a Mac to 'borrow' for the disk utility test you mentioned. I'll hunt around this afternoon/week but my instinct tells me finding a locally accessable Mac running 3 yr old OS X might not be possible. Again, watch this space, I'll post any further developments.
In the meantime any further assistance or answers to the above questions on determining HDD status would be much appreciated. No progress has yet been made on the original issue of failing to boot.
Many Thanks
Ryan

Turned on fileVault AND firmware password, can't boot into verbose mode?

Just out of curiousity, I turned on fileVault AND firmware password on my retina macbook pro,
and when I boot up holding command-v, instead of getting the firmware password screen, I get the filevault password screen.
Is this normal and expected behaviour?

The firmware password disables that shortcut; verbose mode can still be used by using the Terminal to change the NVRAM boot arguments, which requires an administrator password.

How to disable the verbose mode in HTTPS ?

Hello Everybody,
I'd like to know how I can make an https connection in which the text of the transaction with the distant server doesn't show in the console
here is my code :
URL rawURL = new URL(url);
if(rawURL.getProtocol().startsWith("https"))
     System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
     System.setProperty("javax.net.debug","ssl,handshake,data,trustmanager");
     Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
     TrustManager[] trustAllCerts = new TrustManager[]{
     new X509TrustManager()
          public void checkClientTrusted(X509Certificate[] chain, String authType) {}
          public void checkServerTrusted(X509Certificate[] chain, String authType) {}
          public X509Certificate[] getAcceptedIssuers() {
               return null;
     HostnameVerifier hv = new HostnameVerifier()
                     public boolean verify(String urlHostName, SSLSession session)
                          return true;
     /*Initialisation de la connection*/
     try
          SSLContext sc = SSLContext.getInstance("SSL");
          sc.init(null, trustAllCerts, new java.security.SecureRandom());                         HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
          HttpsURLConnection.setDefaultHostnameVerifier(hv);
          HttpsURLConnection.setFollowRedirects(false);
     catch(NoSuchAlgorithmException nsae){}
     catch(KeyManagementException kme)
                     kme.printStackTrace();
     /* creation de la connection */
     urlCon = ((HttpsURLConnection)rawURL.openConnection());
urlCon.setInstanceFollowRedirects(true);
urlCon.setReadTimeout(12000);
urlCon.setConnectTimeout(7000);
urlCon.addRequestProperty("User-Agent","Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.7.12) Gecko/20050922 Firefox/1.0.7 (Debian package 1.0.7-1)");
urlCon.addRequestProperty("Host",urlCon.getURL().getHost());
urlCon.addRequestProperty("Accept-Language", "fr,fr-fr;q=0.8,en-us;q=0.5,en;q=0.3");
switch (urlCon.getResponseCode())
}Thank's !

     System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");You don't need that unless you're running 1.3 or earlier.
     System.setProperty("javax.net.debug","ssl,handshake,data,trustmanager");You don't need that unless you want verbose mode.
     Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());You don't need that unless you're running 1.3 or earlier.
     TrustManager[] trustAllCerts = new TrustManager[]{You don't need this thing at all unless you like (a) code that doesn't implement its specification correctly and (b) insecure code. If your truststore doesn't trust the server certificate, that's the server's problem. Get them to fix it, by getting their certificate signed by a recognized CA.
     HostnameVerifier hv = new HostnameVerifier()Much the same remarks. This piece of code is insecure and it just addresses a problem with the server certificate. Get the problem fixed.
Otherwise in both cases you may as well not be using HTTPS at all - there is no security.
     catch(NoSuchAlgorithmException nsae){}Never ignore an exception.
urlCon.setInstanceFollowRedirects(true);If you have that you don't need the global setFollowRedirects call above, so you should remove it.

Boots up almost like verbose mode.

I have an Intel iMac that seems to work fine, that we have reinstalled Leopard on several times, but everytime we startup the machine, I get a black screen with some white text (almost like it was starting up in verbose mode) then it goes away and goes to the login screen. Then when I shutdown, it logs me off, and then goes back to the black screen/white text, and shuts down. Basically I'm not getting the grey screen with the gear, but instead I'm being shown how the computer is booting up, how do I get rid of this?

Restart the computer with the Option, Command, P, and R keys held down, and release the keys when you hear the second startup chime.

How to start up MAC mini only in the verbose mode (command line) , no GUI

Can anyone let me know how I can set up the mac mini to ALWAYS boot into a verbose mode only, no GUI interfaces at all?
Mac Mini Mac OS X (10.4.6)
Mac Mini Mac OS X (10.4.6)

Hi, Andy your replies are really helpful. I did tried your method and also followed the link http://www.oreillynet.com/pub/h/348
Now my mac mini - Tiger seems hanging forever at the boot up screen. A Apple log showed up with a message "Starting Mac OS X ..." and now almost 5 minutes passed, nothing happened ...

How to start Weblogic 9.1 in verbose mode

Hi all,
I need to start Weblogic 9.1 in verbose mode.
We have just recently migrated from weblogic 8 sp3 to weblogic 9.1. In weblogic 8 sp3, the option
"-Dweblogic.ejb20.cmp.rdbms.codegen.verbose=true"
would work but it doesn't work with Weblogic 9.1.
Can anyone tell me how to do the same?
Thanks and regards,
Sachidanand

If you close Firefox while in full screen mode then Firefox should reopen in full screen mode the next time.
That choice is saved in the localstore.rdf file in the profile folder.

Verbose mode ****

So it all started a while ago when sleep mode only lasted for 10 seconds after I upgraded to 10.4.9. I read that this was a common problem, so I just shut down at night. About a week ago, the computer kept booting from the gray Apple boot screen straight to the Blue Screen of Death: "You need to restart your computer". Kernel panic. Yay. Always a code 14: page fault.
So I swapped the ram but nothing changed, and I could boot into OSX fine occasionally. No Disc Utility noticed anything wrong. Then yesterday my MBP quit recognizing my external hard drive. I can use the hard drive with Windows machines and my iMac G4 just fine. I've tried to boot in safe mode, but while holding down shift, the gray screen just stays there spinning forever. I can't boot into open-firmware either.
When I put the install disc in and held down C, I got a kernel panic message that said Unable to find driver for this platform : “ACPI”, and now my computer is in verbose mode telling me all kinds of awful things about the mDNSResponder, and " I have no name!#"
I'm fine with backing up my data and reformatting if that's what it takes - but since the MBP won't recongize the hard drive I can't do that. I want to take it to the genius bar tomorrow and see if they can figure out what in the world is going on.
Here's some stuff verbose mode is putting out right now:
mDNSResponder: GetDNSConfig: Error: dnsconfigurationcopy returned NULL
configd[257]: No AirPort Driver found.
configd[257]: LINKLOCAL: inet6attachinterface(en0) failed, File exists (17)

Furthermore, the PRAM reset command won't even load the gray Apple before it restarts (maybe that's normal). I managed to get into Hardware Test mode by holding D.
