Update 3: Correction, I tried again now paying attention to it the whole time, and it wasn’t that the loading bar never filled up at all, it completely fills up, but nothing else ever happens after. Update 2: It wasn’t recognized on the Startup manager either, so I tried all the process all over from the start, and I saw what I had done wrong, I didn’t wait enough for each line to do its thing before entering the next ones, so I just wasted a DVD-RDL disc, this second time it apparently worked, upon boot to Start up manager it was recognized, but after selecting it it seemed to be doing its thing fine, but then it just went to the boot screen with the apple logo and the loading bar underneath it, but the bar never filled up, at all, not part of it, nothing, I left it all night. Update: I managed to create the disc with the commands (still would like to know how to get and run scripts for future references), but reinserting it in the MacBook Pro pops up the message that it isn’t readable by this computer, is that how it’s supposed to behave? I’ll boot to the Startup manager and see what happens. I’m on Catalina, my MacBook Pro became very slow and unresponsive and the battery lasts very little since “upgrading” to it so this is why I want to try Mojave, I tried resetting the NVRAM and that did make it run smooth again, but just for a little while, and didn’t change the too quick battery draining issue, now it’s back as slow and unresponsive, I tried resetting the NVRAM again but this time it didn’t fix it. Since I couldn’t that way I tried running the commands, it asked me to "erase the volume at /Volumes/install_build”, I pressed Y to continue with it, and it gave me an "Error erasing disk error number (22, 0) Sorry for my lack of knowledge in this matter. rtf which seemed to be my only option, I then renamed it to. sh but it wouldn’t allow me to, so I saved is as. But if geekiness is your thing then go ahead and try the dvd.Ĭlick to expand.Hello, could you (or anyone else) please let me know how does one get the script? I don’t see any “download” button nor anything like that, I tried copying and pasting the code in the TextEdit and saving it as. Be aware however that a bootable DVD is much slower to boot up than a usb, so if you want to do it as quickly as possible, then the usb is the way to go, not dvd. So if you want to be really geeky you can try to make a bootable DVD of Mojave. I spoke before on how to make a bootable usb of the Mojave installer at and that is the most efficient way to make a bootable installer.īut some are old fashioned and have bootable disks for every system going way back to Mac OS 7.1 (including high sierra). Hopefully we can have success with Mojave too. Prior to lion you could buy disks from apple. Nevertheless we have so far had success in making dvds of every system from lion to high sierra. But ever since Mavericks it became quite difficult to make a bootable dvd and progress on this has always been experimental. It was easy to make a dvd of lion and mountain lion. If not then maybe we can modify the commands somehow to make it work. I haven't tried this yet and just because it worked in High Sierra doesn't guarantee it will work in Mojave. Where you replace "YOURNAME" with the username for the account you are logged into at the time.Īnd then boot to startup manager with option key to select the dvd and install Mojave from it. Sudo hdiutil burn /Users/YOURNAME/Desktop/Mojave.iso You can then use this to burn it to a dual layer dvd: Hdiutil convert ~/Desktop/InstallSystem.dmg -format UDTO -o ~/Desktop/Mojave.isoĪnd then you can rename to Mojave.iso. Hdiutil detach /Volumes/Install\ macOS\ Mojave Sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia -volume /Volumes/install_build Hdiutil attach /tmp/ -noverify -mountpoint /Volumes/install_build Hdiutil create -o /tmp/Mojave.cdr -size 8000m -layout SPUD -fs HFS+J Then run the following commands in terminal: You can get it here: from the mac app store if you haven’t already. So modifying the commands in that thread (which previously successfully made a bootable dvd of high sierra) we could proceed thusly:įirst you have to have the full installer of Mojave in your Applications folder. We could base a method on what we did previously for High Sierra at
