my rebuild from the full 10.9.2 installer has resolved the issue however looks like I need to run the script. I can book a late 2013 iMac and MacBook Air but not a 2010 MBP. I am hoping for that LotusHaney's script takes care of it!

SUCCESS.... The steps I took are a fresh build of a 10.9.2 Netboot DMG from scratch (MUST use the 10.9.2 full installer as per Apple above) and Lotusshaney's script (which is brilliant and perfect for non coders like me) and now I can boot my 2010 and 2013 equipment. (Huge Thank You Lotus..) Has anyone logged this with Apple? With this level of self support, we mise well be Apple employee's! ;-o

@Kkrawchuk The combo updater will create an agnostic image.

LOL...we try to "break" things by using the combo updater on an old(ish) Mac. :)

I can confirm that swapping the kextcache worked on a 2012 mac mini i was having issues with and on an older iMac. Very cool, that no entry sign has been popping up and recreating images was taking up a lot of time without any decent results.

@ Don, the combo thing didn't work for me…however

sudo rm /System/Library/Extensions/IO80211Family.kext/
sudo rm /System/Library/Extensions/ATTO*

Did. :) Thanks guys!!!

I have also read that you can swap the kernelcache file from the NetInstall image : )


Forum|alt.badge.img+7

that was hard work. i couldn't get a proper NBI because the SIU wouldn't play ball with the system image I had. Eventually created a frankenstein monster NBI using the DMG I wanted, a booter from a recent-ish NBI, an edited PlatformSupport.plist so the new MacPro6 wouldn't refuse, and a kernelcache from the recipes in above posts to enable all models to TFTP that ok.

*stares very hard at Apple*

Hi All,

I've used the script mentioned here: http://blog.designed79.co.uk/?p=1807

BUT, i'm finding imaging is incredibly slow.. The OS block copy is taking hours..

Anyone else seen the same?

@bentoms Is that a newish mac with USB 3 and your using a USB dongle ?

It was reported on macenterprise google groups that the USB dongles have a nasty habit of defaulting down to 10Mb speed when doing the auto negotiation. The thunderbolt dongles apparently do not have this issue.

I've had something similar here. I rebuilt the image again (using the rc.netboot modification), got SIU to build it properly with an under 32Mb kernel cache file (no idea how, it just started working ok) and uploaded.

I really don't know if it was net boot image, our persistent DP filesystem issues or 10.9.2 at this point.

Thanks, everyone, for this thread. This was a huge headache for us. Discovering the kernelcache size issue was a goldmine. Thanks @Lotusshaney for creating that great script. For us, running the combo updater on both the server and NetBoot source volume + resizing the kernel cache seemed to do the trick!

I had experienced Casper Imaging (9.22) crashing until I downloaded and ran Lotusshaney's script makecachedrop and added the 10 GB of free space. (answer y to the 10 GB)

This stopped the crashing, allowed the imaging to complete (reboot to first run) and eliminated my "out of disk space" errors.

His script also resolved the "DO Not Enter" while netbooting older equipment, needless to say I have many copies of the script hidden away so I am never without! :)

Thanks again Lotus, MUCH appreciated!!!

Just an update.

Our issue with Imaging speed was due to an over zealous AV policy vein deployed to the Mac servers.

Did anyone else notice that Apple released an updated version of IncompatibleKextConfigData.pkg on 3/3/2014? This newest version is 1.23 as opposed to version 1.22 that came out on the 2/27/14 along with 10.9.2. I am wondering if this folder (/System/Library/Extentions/AppleKextExcludeList.kext) is used in determining which kexts are used during NBI creation.

yeah because the last seed program was only 9 weeks long. Maybe you should wait for 10.10 :)

I was tweaking Lotus's base script today when I figured I would just try Pepijn's experiment.

While I can't confirm (yet) that it works on a machine that didn't work previously I can confirm that there appears to be no ill effects to taking the kernelcache from a Netinstall and dropping it in a Netboot.

Tweaks = https://github.com/rmanly/scripts/blob/master/makecachescripts/makecache.sh

Sorry for the little sidestep- but talking Netboot: I have a NetSUS 3.0 which when I boot with the "option"-Key is shown as bootable volume under the name "Faux Netboot".
That works now great - thanx to the kernel cache trick.
But I do not see the "Faux Netboot" when I open the System Preferences -> Startup Disk

Sorry if I am bringing up an old thread, but I encountered a problem creating netrestore images this week that was driving me crazy and wanted to post the solution in case it helped others....

I created netrestore images from a 10.9.1 that was combo updated to 10.9.2. It would boot fine on older macs, but 2013 Macs would just give the no-entry sign. Just for kicks, I booted an older mac and dropped into terminal from the installer (not the installed image) and checked the system version with sw_vers. Lo and behold, it was 10.9.1 even though the restored image was 10.9.2.

So, this led me to believe that the Apple image utility might be grabbing a stale kextcache, or... maybe it is grabbing it from the restore partition. In any case, I used a script to update the restore partition to 10.9.2, regenerated the image, and that booted on the 2013 Macbooks. No fresh install of 10.9.2 was needed.

That would explain why Apple is telling people to install 10.9.2 vs, update, as only the installer updates the restore partition unless you do it manually. It could be there are two issues at play... the 32MB tftp limit and the restore partition. That could explain the rather hit or miss results.

The Macworld link talks about Lion, but it works for Mavericks too, but you still need the Lion Recovery Update for it to grab a tool from that dmg. You will need the Lion Recovery Update dmg as well as the Mavericks 10.9.2 App store download.

So if you are still having trouble with 10.9.2 nbi set try Zapping Pram and emptying the kernal cache (holding shift on startup) then restart. This is how I was able to fix the my inability to net boot

@Deadzak resetting PRAM and holding shift did nothing to get the old Mac to boot. Still have to chop stuff out of Extensions to get the old computers to boot.
