Computer recommendations

These settings are not required for the installation, but they prevent the device being stopped and errors during local audit.

Full Disk Access after every update

After every new installation, open System Settings > Privacy & Security > Full Disk Access, turn the switch next to OSFISKAL L-PFR servis off and on again. Otherwise local audit to a USB drive does not work. See Installation on macOS.

Sleep

While the Mac is asleep, the device signs no receipts and sends no data. In System Settings > Energy, turn on the option that keeps the computer from sleeping automatically when the display is off.

Restarting the computer

After every restart, including one started by a macOS update, the secure element's PIN is entered again in the device window.

Device memory

Do not delete or move the folder /Library/Application Support/osfiskal-lpfr. It holds the receipts and data the Tax Administration has not collected yet, and it is the taxpayer's data.
