STRANGE CHINESE MESSAGE RECEIVED DURING MY MAC UPDATE
I left my Mac M1 mini on last night so that the operating system could be updated. During the updating process, the computer started talking to me in a language I think was Chinese. There was also some wording on the screen which I was unable to read before it disappeared. I checked my computer this morning and found that the operating system was now Sonoma 14.1.2 which I think is the updated Mac OS. Has anyone any information on this? Have I been hacked and are all my passwords which are kept securely in a Sparse Image folder (literally hundreds of them) been hacked? I should add that via my iPhone 8 in the last few weeks I've received several calls and voicemails in Chinese. When I checked the origin of these calls, they came from a source advised as spam or fraudulent.
