Support FAQ

Known major issues / workarounds:

Time Machine Comparison (pre-APFS) is blank after app restart.
Some Time Machine comparisons lose their values due to app Sandboxing. This will not be addressed in a future update as the pre-APFS Time Machine comparison is deprecated and not available for newer Time Machine archives. To work around this please give access again by recreating the comparison or comparing against the Time Machine folder. Please note that direct comparison against Time Machine folders is not very useful and Time Machine archives are not meant to be modified. This suggestion is only to get back access to those folders via the app.
