PippoX0 Posted January 31, 2017 Share Posted January 31, 2017 Hi, just for fun , i created a bootable OSX Sierra installation DVD. Wow, i didn't remember how much time it takes to load before you can get install screen ... ( 11 minutes ...) ( even on Intel i5 quad-core and 8Gb of ram) I stopped i don't want to know how much time it takes to fully install on HD...... However it remembers me when DVD was the only way to install OSX ...

JahStories Posted January 31, 2017 Share Posted January 31, 2017 Nice! I didn't knew it was possible to create dvd for Sierra installation! Yes btw it was really bad!! Link to comment Share on other sites More sharing options...
PippoX0 Posted January 31, 2017 Author Share Posted January 31, 2017 Yeah, sometimes i like to try old stuff on new OS. BTW to creare a Bootable DVD is an easy task : 1) Create a Legacy bootable USB as you prefer ( Clover o Enoch bootloader) 2) Create a dummy DMG with 8Gb of space ( i.e. Sierra) 3) Restore USB on DMG with Disk utility or Carbon Copy Cloner 4) Re- install legacy Booloader on DMG *** This is optional, because all should be just fine ... *** 5) Create an hybrid ISO HFs+ Jolilet with Cdrom-boot option (here is the magic .... ) sudo hdiutil makehybrid -o "Desktop/DVD.iso" "/Volumes/Sierra/" -iso -hfs -joliet -eltorito-boot "/Volumes/Sierra/usr/standalone/i386/cdboot" -no-emul-boot -hfs-volume-name "OSX Sierra Install DVD" -joliet-volume-name "OSX Sierra Install DVD" 6) Burn ISO with Disk Utility on a Double-layer DVD. That's All 3 Link to comment Share on other sites More sharing options...

That's All That is not all. Legacy boot sector is machine code. https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/hdiutil.1.html makehybrid is create file system,not boot sector machine code,there is no hybrid iso,because iso does not equal file system. your method maybe enough,but not retail DVD Link to comment Share on other sites More sharing options...
PippoX0 Posted February 1, 2017 Author Share Posted February 1, 2017 Hi, Boot sector code is inside /Volumes/Sierra/usr/standalone/i386/cdboot file. -eltorito-boot <cdboot> and -no-emul-boot option are needed to make iso bootable. Enoch bootloader install cdrom bootsector code in //usr/standalone/i386/ folder, during setup. I don't Know it this method works with Clover , on Enoch/Chameleon works fine .... You're right -> it is not a retail DVD , it's for Hackintosh PC only ... ( Legacy ones) Retail DVDs are for real Mac ... See Ya Link to comment Share on other sites More sharing options...

See Ya thank you for your information,I do not know eltorito can work with makehybrid,eltorito=dd,makehybrid=cp,different.how about all with dd?
