CloverLeaf Posted March 7, 2025 Share Posted March 7, 2025 This will be very challenging. What process/guide did you follow? Quote Link to comment https://www.insanelymac.com/forum/topic/360750-efi-for-hp-probook-450-g9/#findComment-2830753 Share on other sites More sharing options...
Christop Posted March 7, 2025 Share Posted March 7, 2025 (edited) Hello Bartosz Nowacki! Regarding your case, when you encounter the error "no start and freeze", it may be due to an error in the bootloader setup or a problem with the kernel. Try checking verbose boot (by pressing -v when booting) to find out more details about the error. Thanks, please reply to this answer if correct.

etorix Posted March 7, 2025 Share Posted March 7, 2025 The iGPU is not supported. Even if you manage to boot you will NOT like the experience of living with the VESA driver. In short: Don't try. 3 Quote Link to comment https://www.insanelymac.com/forum/topic/360750-efi-for-hp-probook-450-g9/#findComment-2830756 Share on other sites More sharing options...
Roby26 Posted June 30, 2025 Share Posted June 30, 2025 I have an HP Probook 430 g7 and using Opcore simplify I managed to install Mac OS Tahoe, everything works except Wifi, which I solved using the Heliport application and the itlwm kext. Have you tried Opcore simplify? Quote Link to comment https://www.insanelymac.com/forum/topic/360750-efi-for-hp-probook-450-g9/#findComment-2835576 Share on other sites More sharing options...
