Hi!



I have recently stumbled upon an issue with netbooting older MBP's to my latest 10.9 NBI. Every time I try to boot I get the prohibitory symbol. I can't figure it out and it is driving me insane. I have tried the following:



Making sure the NBI has no spaces in the name
Deleted some Kernel Extensions to make the kernelcache < 35 mb
Set the NBI as default



I really want to try and have a universal NBI for my helpdesk folks, but if this cant be done, I understand. Just wanted to know if anyone has seen this problem?



Also, I used the System Image Utility Tool to build the NBI

My initial thought would be to turn on verbose boot and see if you can discern *why* it's not booting via the onscreen output:



sudo nvram boot-args="-v"


Obviously, you'd need access to a recovery partition or bootable OS to execute that.



Additionally, what build of Mac OS X is your NBI? Some builds only play nice with specific hardware, which can make having a 'universal build' difficult. It's doable in many cases, but often requires a good bit of work and pain, in my experience.

disregard. Didn't read subject.

These two links helped solved the problem:
