Apple did a really bad shitty of testing the upgrade to Sonoma. I struggled with this issue for weeks and tried every workaround offered in these forms and elsewhere ( Reddit ) . Nothing worked. Computer : MacBookPro with an Apple M1 Pro Chip runing Sonoma 14.1.1 Symptoms on my computer : Spotlight totally stopped working Mail search totally busted - Mail always shows status as Indexing What all i tried unsuccessfully erase and rebuild of Spotlight Index Rebuild Mail Database all the mdUtil Workarounds from Terminal (mdutil -ai off / on etc ) login / logoff from icloud What i discovered The problem is that after the Sonoma installation the secure token got corrupted and i saw "authentication disabled" errors on trying to do admin actions. What finally fixed the issue Did the following operation from a local admin account sysadminctl -secureTokenOff sysadminctl -secureTokenOn logged back into my account . Everythign works ! Thank you Apple for killing my productivity and shame on you for not testing this workflow properly , to add ti this so many months after release you dont even have a fix !
