DVD RW ejected without opening on MBP

Hi! I have a multiple problem, but lets start with one question...

I have a DVD RW 4.7GB (I want to use as a bootable disc for an eMac).

But to start with, when I put it in my MBP Mid 2012, OSX 10.13 it is ejected after spinning a bit. Other CD do open fine...

I tried inserting this DVD RW in a Windows PC and it DOES OPEN! I can format it, put files on it etc.....

Any suggestions please...?

Thanks in advance for all your time!

Instead of fighting the issue you can easily create bootable USBinstaller per the instructions here:

Although I think your link talks about the more modern OS, i need OS 10.4.11 PPC (I have found on on archive.org and downloaded it both in .dmg and .iso). I tried installing .dmg on USB keys, and it seems to be installed but when I plug the USB ans reboot the old eMac it doesn't open up as an option at all....


Thes old OSX shipped on a ROM Disk— what was 10.4 Tiger(?)


I do recall making a bootable DVD w/Lion as they phased out portable media installers...


see if this is applicable to your 10.4

Control click your .dmg to open the >Show package Content>  InstallESD.dmg



It is possible a local Macintosh user group would have access to an old 10.4 ..(?)

Yes Tiger.... Now coming back to a DVD... that is when this DVD RW doesn't stay in my mbp, it is ejected after having spun a bit... without opening up...


This would be on your Desktop prior to creating the DVD...


"show package content" which opens up a "content" folder.


Open the Contents folder and poke around...

yes... ok so you meant after having burnt the DVD. Can it be a CD or DVD? Whatever? (also i didn't know about these Apple user groups its sounds great!!!)


?

I hardly doubt a CD has the capacity to hold GB of data— DVD or double side DVD...depending


This is all going too far back for me to keep up with.
