A partial workaround for Isaac/Mac on macOS 11.4+ and M1 Macs

Post by Velocomp »

IF ISAAC/MAC IS NOT CRASHING WHEN YOU LAUNCH IT ON YOUR MAC, THEN IGNORE THIS POST!!!

If you are running the latest version of MacOS Big Sur, or are using a Mac with the new “M1” CPU, then you have found out that Isaac/Mac crashes whenever it is launched.

The crashes occur because the National Instruments “NI VISA” drivers used by Isaac/Mac are not compatible with macOS 11.4+. Until the NI VISA drivers are updated by National Instruments, your Velocomp device will not be able to communicate with Isaac/Mac. That’s bad news… (we do want to mention that Intel Mac computers can install a VM, then use Isaac/Windows to download ride files).

The GOOD NEWS is that the incompatible NI VISA drivers, after being uninstalled from your Mac, make it possible for Isaac/Mac to launch, both on the latest Intel Macs and the new M1 Macs. You will be able to open/analyze your previously downloaded and stored .ibr ride files with Isaac/Mac.

If Isaac/Mac crashes when you launch it on your Mac, you will need to remove the NI VISA drivers. Follow the attached instructions to remove the drivers (this is a tedious but straightforward process, and you’ll have to do it only one time).

AFTER YOU REMOVE THE NI VISA DRIVERS, LAUNCH ISAAC/MAC. IT SHOULD WORK WITHOUT PROBLEMS.

If Isaac/Mac still crashes after uninstalling the NI VISA drivers, then install the "LabVIEW2021RuntimeEngine" attached. After doing this you should be able to run Isaac/Mac.

NOTE: M1 Macs will need to have the "Rosetta" application installed. Your M1 Mac will give you this message if needed.

I am really sorry the Mac world has become such a nightmare for our users (and for us as developers). This workaround is not ideal, but half a loaf is better than none. :D

What are the installation instructions for an Intel/MacOS 11.6 with a prior installation under Catalina that worked and then got broken by upgrade to Big Sur, an installation since reversed (all known NI, SI and other stuff uninstalled) - some per documented instructions and others no - which may be a fresh installation? Thanks

I don't understand your question, but here is a summary of where we are:

1) If you have 11.6 installed on your Mac, Isaac/Mac won't work, even if Isaac did work under Catalina

2) The problem with recent installations is incompatibilities between NI-VISA drivers and recent versions of macOS (11.4 or higher)

3) This thread tells you how to uninstall the NI_VISA drivers from your macOS 11.4+ Mac. After driver uninstallation, Isaac/Mac won't crash, and you will be able to launch Isaac/Mac and review old ride files. This workaround functions both with Intel Macs and M1 Macs

4) If you want to download files on your Intel Mac, you'll have to install a virtual machine (Parallels works) and then Isaac/Windows

5) Note that VMs don't work on M1 Macs.

Thanks for this. Point 3 is pivotal: hadn't realized that, with incompatible driver uninstall, only old files can be read but no new sync possible - got that Isaac wouldn't crash. Assuming there's no relief for Mac users for Isaac unless we want to incur additional expense of Parallels. Or has anyone tried vBox Catalina instance, for example, as free option?

I think there is a free version of Parallels, and also VMWare

John is correct - both of these VM applications now have free versions.

You can choose to run Windows 10 (need to have the key) or an earlier version of a MacOS - Catalina, High Sierra,...

If you start from scratch, you can install Windows 11, too ---- information on Parallels web site - https://www.parallels.com.
