formatted flash
now netinstall is not installing - sending offer
missing probably the netbios setting mentioned above all other settings Ive already tried
tried many combos of the mentioned and other solutions found by me in the past, nothing worked this time
must try Linux cli next
please give hints if you know any
How was flash formatted? Netinstall does it, but IIRC it doesn’t explicitly say at which stage it’s done. So I’m guessing you did it in some other way?
by RouterBOOT 6.43.12
Success with native booted Linux.
Ohhh yeah. 
Yup Item f. LOL

H. NETINSTALL & PROTECTED ROUTER BOOT MODE (PBRM)
NETINSTALL should be used if any security concerns arise OR if your firmware version seems to be acting strangely or the firmware version is really old!!
PBRM is mainly activated/used by those ‘loaning’ routers to customers and want to retain control over the firmware. viewtopic.php?t=181158

Also, another way of getting your unit(s) up to date is to netinstall devices, especially if going from a really OLD firmware to the LATEST firmware. I would say it’s preferred because it also installs recent default configuration, while upgrades convert running configuration. A few versions between your running ROS and current one brought some big changes and it is possible for upgrade process to fail to convert old config to new one. In addition, new default configs makes much more secure setup in certain aspects.
In other words, if you are many firmware versions behind, netinstall is the least painless way to get to the latest config and is more secure.
Note: Upgrading, when WIFI is involved is to 7.13 and beyond is best done through netinstall, otherwise you need to go through 7.12 first and then 7.13 or beyond (by normal upgrad process).
Sage tips/advice on NetInstall if having difficulties ( USE ETHER1 OR the port named BOOT ) …
a. Regarding Etherboot for all devices, the most error-free method is - to press the reset button, keep it pressed, power on the device, and wait until the device shows up in the NetInstall window, then release the button. This holds true for the Audience as well.
b. Try to have a direct cable connection between computer and device (laptop to device for example).
c. A trick which helps for some is to only use a dumb switch in between, nothing else connected.
d. Also on THE COMPUTER being used to run netinstall, there may be issues if there are multiple NETWORK interfaces. If experiencing difficulties on the PC, it is best to ensure all other NETWORK interfaces are turned off.
e. Enable NETBIOS, over TCP/IP ( active vice automatic or disabled )!
f. Apparently (fart, belch) some users have success using a LINUX computer vice Windows… hard to believe but worth it if no luck otherwise !
g. A forum post on the subject with some ideas → viewtopic.php?t=109086&sid=2c700617e89d … 1660a296ef
User Comment: In my experience, Netinstall often fails to detect devices after the ethernet link to the MT device goes down and up again while netinstall is running.
Either place a dumb switch between the PC and the MT box to netinstall, so the PC ethernet link stays up during reboot while entering Etherboot.
Or first put the MT box in Etherboot mode, wait for the link to come up and start Netinstall after the link is up.
User Comment: Useof displayed or entered mac-address vice IP address in winbox needs to be emphasized.

Do you have the un-truncated URL?
It’s not THAT hard to reconstruct …
https://tangentsoft.com/mikrotik/wiki?name=NetInstall+on+EL9&p
Maybe, and maybe not. The file at that URL has lots of mentions of Windows and Linuxes, but not a word about Macs. Or perhaps the phrase “FOR MAC” meant something else.
There is the first part up until wiki and then the text shows EL9.
There is only 1 entry in that wiki referring to EL9.
So still rather easy to reconstruct, I would say ? 
I do agree though that page doesn’t say anything about MAC. The only thing I could see was note 3 related to Parallels.
This worked for me (hEX Lite RB750r2 and W10p):
A simple Switch between Laptop and Router
(The router disconnect a couple of times during Etherboot - this is enough to confuse w10)
Tried all the things in this thread - but its not necessary
Used a usb-ethernet adaptor
Running as administrator
Running W7 compatibility
Changing from auto metric to 1
tcp/ip advanced wins - activate NetBios over tcp/ip
You still need to:
Follow the guide for netinstall on mikrotik wiki
Enable Netinstall in firewall on public net
Yes, having the link going up and down on device reboot confuses Windows and/or Netinstall.
One way to avoid this is to use a dumb (unmanaged) switch in-between.
Another way is to boot your MT device into netboot mode and wait until link is up again before staring netinstall.
Once the MT device is in netboot mode, has stable link and has started to send boot requests (visible on the Ethernet port activity LED), start netinstall.
At least for me this reliably makes netinstall immediately “see” the device and works.
The root cause is MT devices send netboot requests to the broadcast IP (255.255.255.255) and Windows is somewhat random on deciding to receive or discard such broadcasts on IP interfaces. Especially if link goes up and down and if there is more than one IP interface.
