- Netbooting is too slow
- It takes more than 30 minutes to get to Task Sequence window
- Netboot server and Mac are located in the same network
This behavior is observed if Mac from which image has been created has OS X version that is different from OS X version installed in Recovery partition.
You can check OS X versions by running pmm_osd_image_builder tool that is used to create a netboot image as described in Creating an OS X Boot Image at page 102 of Parallels Mac Management Administrator Guide:
Note: you can interrupt the process by pressing ctrl+c combination.
Update Recovery partition to the latest build:
Disable System Integrity Protection (required only for OS X El Capitan and later):
- Boot in recovery mode.
- Open Terminal from the Utilities menu.
Execute the following command:
Download the Lion Recovery Update from here in ~/Downloads folder on your Mac.
Note: Although tool is called Lion, it will work on El Capitan fluently.
Download .app installer of OS X system that is currently installed on your Mac in ~/Downloads folder. We recommend updating OS X to the latest version available and then download installer from App Store.
Right click on the .app installer file > Show Package Contents. Go to Contents/SharedSupport/. Copy the InstallESD.dmg file in ~/Downloads folder.
Download recovery.sh script in ~/Downloads folder.
Open Terminal and give execute permissions to downloaded script:
sudo chmod +x ~/Downloads/recovery.sh
Run Recovery update
cd ~/Downloads sudo ./recovery.sh
Wait till update is finished and reboot Mac.
- Now you can create a Netboot image following Creating an OS X Boot Image at page 102 of Parallels Mac Management Administrator Guide
