luxinhaus Posted January 9 Share Posted January 9 It has been 5yrs and thought do a fresh and newer OS installation. Downloaded macOS Sequoia and created a USB installer using createinstallmedia. Everything went fine from booting the USB, formating the current SSD & choosing the target SSD. Until the message popup “internet connection is required to install macOS” Since i have a my ethernet kext loaded in EFI, i plugged the cable and started the installation again. There was no message this time, looking at the log, its kind of downloading some files & installation went thru. As far as i recall, there was no need for this back then. Has something changed? How can i bypass the need of internet on a FULL OFFLINE USB INSTALLER?

Max.1974 Posted January 9 Share Posted January 9 (edited) I think even when using a bootable installer (via USB, for example), the Mac still needs an internet connection during the installation process to obtain firmware information and other hardware model–specific details. Im not sure, but maybe this starting with Sequoia... https://support.apple.com/en-us/101578 Edited January 9 by Max.1974 1 Link to comment https://www.insanelymac.com/forum/topic/362195-%E2%80%9Cinternet-connection-is-required-to-install-macos%E2%80%9D/#findComment-2846167 Share on other sites More sharing options...
iaihc Posted January 10 Share Posted January 10 It requires an internet connection. If I disconnect the internet during the upgrade process, the entire app cannot be upgraded. 2 Link to comment https://www.insanelymac.com/forum/topic/362195-%E2%80%9Cinternet-connection-is-required-to-install-macos%E2%80%9D/#findComment-2846168 Share on other sites More sharing options...
LockDown Posted January 10 Share Posted January 10 The only way for me to do fresh without the need of internet is by using startosinstall or installling it within a running OS and selecting a target drive. 1 Link to comment https://www.insanelymac.com/forum/topic/362195-%E2%80%9Cinternet-connection-is-required-to-install-macos%E2%80%9D/#findComment-2846169 Share on other sites More sharing options...
