For the first time in over 30 years, the newest Mac system software comes with an all-new filesystem: APFS (replacing the venerable HFS/HFS+, which has been around since 1985). While it has many advantages, APFS drops support for certain filesystem features that Mac applications such as MoneyWorks have been relying on for over 25 years. That has required some under-the-hood changes to the way MoneyWorks manages files. These changes were made in v8.
MoneyWorks 8 on High Sierra : ✅
MoneyWorks 8 has full support for APFS
MoneyWorks 8 on Mac is able to run from and open files on APFS-formatted SSDs or HDs as well as HFS+ formatted ones. As an added bonus, the changes made to support APFS also allow it use files stored on FAT32 and SMB volumes (although we strongly advise against doing so). When you upgrade your SSD-equipped Mac to High Sierra, your SSD will be converted from HFS+ to APFS, so please make sure you are running MoneyWorks 8.0.7 or later before upgrading your Mac to macOS High Sierra. Should any new compatibility issues be discovered with High Sierra, MoneyWoks 8 will receive updates to address them as necessary.
MoneyWorks 7 on High Sierra : ⚠️
MoneyWorks 7 and earlier cannot use files stored on APFS-formatted drives
Although MoneyWorks 7 will run on High Sierra (with some issues), it cannot access MoneyWorks data files that are stored on APFS volumes, and since the High Sierra upgrade process will convert your SSD to APFS, you will not be able to open files. If your Mac has a conventional old-fashioned spinning hard disk instead of an SSD, the High Sierra update will retain the HFS+ formatting, so will not cause any incompatibilities with MoneyWorks 7 that we are aware of.
If you are on MoneyWorks 7 or earlier and wish to use macOS 10.13 High Sierra on your Mac, we urge you to upgrade to MoneyWorks 8.
