Latest Mac OS, latest version of Quicken Classic Deluxe Mac v8.2.1. After using Quicken for years on the Mac, I'm having a real issue. I hold security "T" in two accounts. Both accounts are off fractionally in their total "T" holding comparing to an end of month statement for the same security. Entering an adjustment transaction in each account for "T" has no impact on total position. I called Quicken support. After troubleshooting, corrupt file they say. Start all over. Lose years of transaction detail. Rebuild over 30 accounts. One month later, same issue happens again. Entering security adjustments does not impact total holding. This started happening within the last 4 months. I do not store this data file on the cloud. Any ideas?
