• Added support for Mac. The app can now be installed on Apple Silicon Macs running Golden Gate or later from the Mac App Store.

On the Mac, the app adopts a more compact interface than on iPads to allow it to be used as a small floating window alongside other apps, much as a physical calculator is used on a real desk. In its full-size view (i.e. landscape), the app is roughly the same size as an iPad mini in landscape orientation but it is smaller in its collapsed (i.e. portrait) view.

Since there is no notion of rotation on the Mac, the display can be switched between showing just the calculator or the calculator and printer like on iPads by either using the Mac menu bar's i41CX+ > Window > Zoom menu item or by dragging either edge of the app window to expand or collapse it horizontally. Swapping the positions of the calculator and the printer in the landscape view works just like on the iPad by using a horizontal swipe.

NOTE: Because there is always a hardware keyboard on the Mac, the "Alpha Entry" switch setting is ignored and all entry can be done via the keyboard just like when using a hardware/Bluetooth keyboard on the iPhone/iPad. With a few exceptions (see below), the hardware keyboard keys are mapped according to the ALPHA mode labels shown on the keypad. For example, 'K' is mapped to XEQ and shifted 'K' is mapped to SHIFT XEQ (ASN). Numerical and arithmetic operator keys are mapped directly. For example, the hardware keyboard sequence "6 return 7 *" calculates the product of 6 and 7. The exceptions to these rules are listed below.

! → ON
@ → USER
# → toggle overlay/skin/display control panel
$ → PRGM
% → ALPHA
` → SHIFT
tab → R/S
' → VIEW/AVIEW
return → ENTER in normal mode, exit ALPHA in ALPHA mode
＞ → SST
＜ → BST
{ → CLX/A
shift N → CAT
shift K → ASN in normal mode, append in ALPHA mode
shift L → LBL in normal mode, ASTO in ALPHA mode
shift M → GTO in normal mode, ARCL in ALPHA mode
Q~Z, =, ?, :, space, and comma → the SHIFT'ed functions on the labelled keys

( → switch between printer and calculator views
) → switch between calculator and back views
& → toggle printer on/off
[, ] → switch printer mode left, right
| → print
; → paper advance
_ → tear paper roll
} → new paper roll
