I just updated to MacOS X Catalina on this 2015 model i7 (and it was updated last night).

You would think a 'Pro' version of anything wasn't such a snowflake. My son took the (2019?) i9 off to college with him because he cracked the right screen edge on this one (which we, the parents, have to deal with, now). I am well aware it is old (and unsupported), but it is very upgradable and was affordable. I bought it at a great price, and it is immaculate as it just sat in a corner of a business unused. I am not trying to install OS X Software to any-non compatible device like a Windows PC! This is just for personal restoration of my old iMac.ĭoes Catalina No Longer Support Bootable MacOS X Partitions on Flash Drives when Formatting as Mac Journaled? I am having great difficulty trying to install a MacOS X that actually works on my mid 2011 27' iMac. Maybe it's possible to burn the dmg file to two separate CD's? I don't actually know if it works but I just wanted to mention it. I don't know it it's possible but when I installed OS X Leopard I had 2 Installation CD's and while it was installing it told me to insert the second CD to continue the installation. Which command do I pick? The command for El Capitan or the command for macOS Monterey? I have macOS Monterey installed on my machine. I want to create a bootable El Capitan USB-Stick. Also how to I know which one I have to pick? I replaced the / myVolume with the name of my USB-Stick. I also have a question about these commands. I already tried the Terminal Codes that can be found by clicking here MacBook Pro 2018 - macOS Monterey iMac 2008 - OS X Leopard Thinkpad - Windows 10 Q: How can I create a bootable CD / USB-Stick with OS X Snow Leopard on it, from a dmg file?

My only problem is, that all CD's that I have are only 4,7 GB or 700 MB big and the Update is about 7.5 GB. I have a dmg of the Snow Leopard Update and when opened it, it says I should burn the image to a CD to then start the iMac from the CD. Hey! Im trying to install Snow Leopard on my old iMac but there seems to be a problem. If there is a way to go directly to El Capitan please tell me because im really frustrated. If there is no other way than installing Snow Leopard then read the stuff below. Im just trying to upgrade to El Capitan and not to Snow Leopard.

So if there is a way to skip Snow Leopard and go directly to El Capitan ignore all the other stuff written below. (Important NVRAM and RAM Updates are included in Snow Leopard that are required by OS X El Capitan). I want to install OS X Snow Leopard, because a Chat Support Guy told me that Snow Leopard is required to install El Capitan on my iMac
