Use Mac Core Document Behaviours, not Windows paradigms (e.g. for autosave / recover)
Apps designed specifically for Mac employ Mac Core Document Behaviours, i.e. OS-level methods for handling documents, e.g. autosaving and recovery.
The issues with Mac Excel's document-handling, particularly after force-quitting Excel or forcing a shutdown of the Mac, or a crash:
- Excel presents a pop-up on re-opening ('Excel saved changes to the file' etc.): this pop-up burns CPU until you click on it. But the pop-up isn't required if you're handling documents in 'the Mac way' in any case, as other apps do.
- Excel re-opens docs as 'Last Saved By User' or 'Recovered' (from memory): As a Mac user, I think... so what? Other apps just re-open the last version of the doc with the same name, and do not force me to re-save the doc and have to remember where it was located.
There is no need for Mac Excel to have its own auto-save mechanism and paradigms separately from what already exists in Mac OS.
The operating system handles it.
Please implement this in Mac OS and save us from unnecessary pop-ups and confusing recovered file names and having to manually re-save documents in their correct location etc.
