I recently installed TurboTax which installed a .llb file as an “update” that screwed up my computer. (Shaking fist at Intuit). I had to nuke and pave it. After re-install, all my contacts were duplicated. Using the “Find Duplicates” (and merge) screwed all the contacts up – everyone had the same name.
I downloaded a backup from iCloud from 2 days prior and now half contacts are missing and iOS and Mac won’t stay in sync.
I saw this post saying “big contact photos” can cause problems.
Any thoughts? Thanks - RP
