What should I do if I encounter any problems while installing Mac OS in target disk mode?
If you encounter any problems while installing Mac OS in target disk mode, the first thing you should do is check the compatibility of your computer and the target disk. Make sure that both the computer and the target disk are on the same platform, such as Intel or PowerPC. If they are not, you will need to use a different method to install Mac OS on the target disk.
Once you have confirmed that the computer and target disk are compatible, the next step is to check the connection between the two. Make sure that the cable is properly connected and that there are no loose connections. If everything appears to be connected properly, the next step is to check the settings in the target disk utility. Make sure that the target disk is set to “Mac OS Extended (Journaled)” and that the partition scheme is set to “GUID Partition Table.”
If you have followed all of the above steps and still encounter problems, the next step is to contact Apple Support. They can help you troubleshoot the problem and determine the cause.
