Problems with iOS 14.8.1
What problems are people having with MacBook iOS 14.8.1? For example, I am having trouble with fingerprint id and even with entering my password.
Some people do have problems with macOS (for Macs) 14.8.1, but no more so than any other OS. Sonoma has been around long enough that most issues that are going to be fixed already have been.
There was an update to macOS 14.8.2 released a couple days ago. You might apply that to your Mac and see if it helps.
Otherwise, if you'll describe your problem(s) in finer detail perhaps the best help will be forthcoming.
