DM42 Firmware Update on a Mac
Hi guys,
I have release 3.1 and just saw that the newest version is 3.7. Has anyone of you run the update on a Mac or should I borrow a Windows/Linux machine to do this. I am barely going through the manuals but no mention of Macs. Thanks in advance. Nomad VeHr HP-27, HP-67 ( both legacy), Casio FX880P, HP-35S, WP34S, DM42, HP Prime. |

Please have a look at https://forum.swissmicros.com/viewtopic....917a#p8448.
Beginning with release 3.7 the procedure changed, see https://github.com/swissmicros/DM42PGM/b.../README.md forum.swissmicros.com is recommended regarding questions about SwissMicros products. Release 3.7 is first announced here: https://forum.swissmicros.com/viewtopic....t=20#p8372 (and on the following pages) |

RE: DM42 Firmware Update on a Mac
In addition to what Thomas_Sch wrote above, it may be easier for you to upgrade to V3.5 first since it is all in one piece. Then further upgrades can be done by the FAT method. Actually, there is no real benefit in upgrading from V3.5 to V3.7 if all you want to do is use the calculator, as there are no bug fixes between the V3.5 and V3.7, just organisational changes.
Since installing dfu-util for a one time use may be a bit of a faff, it may be easier to find a friend running Windows 7 who is willing to help you update the firmware. (There are some problems with drivers when doing this on Windows 10. There are workarounds that leave Windows 10 in a slightly compromised state, so it would be unfair to borrow a friend's PC for this task.) |

RE: DM42 Firmware Update on a Mac
I have actually found the upgrade path on the Mac to be easier than on the PC running Windows 10, due to the Windows 10 problems ijabbot mentions. The instructions are pretty clear, though --- follow them exactly and you should have no problems.

Installing dfu-util is easy if you already use Homebrew or MacPorts. (The SwissMicros documentation doesn't mention MacPorts, if I remember correctly, but since I use MacPorts myself and don't like Homebrew, I tried installing dfu-util with MacPorts; it installed a slightly older version than the one Homebrew installs, but it works fine for me.) But yes, install 3.5 and from then on you can install from FAT, which doesn't require anything nonstandard on the Mac or PC side, since mounting USB disks is something they can all do out of the box. |

RE: DM42 Firmware Update on a Mac
Thanks Thomas and ljabbott!
I´m no power user myself but I will look onto these MacPorts thing. One of my friends lent me a Win 10 machine which is rather clunky, but when I tried installing the unsigned driver, it came with a message saying basically that the system policy was blocking installing unsigned drivers. I tried several workarounds after researching, but unsccesfully so far. Since you mention about your success with MacPorts, I will try a crack at it.

RE: DM42 Firmware Update on a Mac
Hi guys,
I did install xcode and macports on my Mac, but now I'm a bit confused with all the instructions out there. Can you provide me simplified instructions on how to update using the DM tool? I am running MacOS High Sierra and downloaded the dm tool file for 64 bit Linux. Thanks in advance. Nomad VeHr HP-27, HP-67 ( both legacy), Casio FX880P, HP-35S, WP34S, DM42, HP Prime. |
