Hello to all,
Much as reported by other posters, Mac OS 15.4 beta1 installation was problematic. In my case for both iMac 13,2 (2012) and MacBook Pro 5,2 (2009 vintage). While installations succeeded with OTA method for
15.4 beat1, build 24E5206s, (original release), I could only boot successfully while in safe mode, whether on iMac or MacBook Pro. Patching would result in an un-bootable machine secondary to Window Server crashes (on both machines), and loss of Bluetooth connectivity. For 13,2 iMac the only viable procedure to restore Bluetooth, when booted into another fully working system, e.g, Sonoma, was to perform SMC reset. External keyboard and mouse were required to allow login (due to loss of Bluetooth connectivity).
iMac 13,2 :
Attempt to use System Recovery to reinstall OS 15.4 beta1 resulted in “
com.apple.buildinfo.preflight.error error 21” message, which blocked re-installation of OS. The error message was indicative of possibly corrupted or incompatible previous installation. I found the Network to function without issues. The only recourse with original beta was to erase the disk and reinstall 15.3.1, then OTA 15.4 beta1; this necessity was rendered moot when revised beta2 was released by Apple.
Sequoia 15.4 beta was
reissued(?) with new build number
macOS 15.4 build 24E5222f. This update was not available through Software Updates in system settings for either machine, but full installer was available for download via OCLP’s “Create macOS installer” function (revised
beta2 was available OTA, via system update, for
silicon Macs).
Downloaded the OS 15.4 beta2 and created USB thumb drive installer. Subsequently booted into the USB drive and installation proceeded without issues. System booted from target SSD external drive and was patched with OCLP 2.3n but, as reported by others already, OCLP 2.2 also works. Rebooted smoothly into fully operational Sequoia 15.4 beta2 build 24E5222f. There should be no reason for application which functioned under 15.3.1 to fail under 15.4 beta2.
No problems or rogue processes noted with system operation or on Activity Monitor, respectively. It would appear the new beta release remedied problems created by original beta1 software.
MacBook Pro. 5,2 (reference for NON-Metal machines)
While I could boot in safe mode under 15.4 beat1, build 24E5206s, the boot fails after installation of macOS 15.4 beta(2) build 24E5222f, resulting in black screen, apple logo, and 1/3 completion of progress bar. Trying to boot in safe mode results in grey screen but, surprisingly, with fully functional trackpad cursor and keyboard backlight; potential indicators of Widow Server crash(?)
Hope this may be of help.
