Using MacOS latest version (Tahoe 26.3) with all updates and running minimal other apps with TT Home & Business was not able import info from last year's PDF created by H&R Block. Then TT started acting strangely such as would not open with double-click only by right-clicking, once open would not become active by using cmd-tab and would need to move other app windows aside and click directly on the title bar to activate TT. No improvement after shut and restart. I was almost completely finished when this behavior started and thus was able to file but now do not trust TT on a Mac. Probably will go back to H&R Block next year but wondered if other Mac users have encountered anything like this.
