WARNING: DO NOT UPGRADE YOUR MAC TO macOS 11.4

Post by Velocomp »

macOS 11.4 causes Isaac/Mac to crash. As of 5/29/21, there is no known solution to workaround the Isaac/Mac problem.

macOS 11.4 ALSO breaks Parallels VM:. You will get this message when attempting to start Parallels:

Fortunately, with the help of forum member lorduintah, there is a workaround to the Parallels problem:

1) Make sure your VM is stopped (not suspended).

2) Go to Parallels Control Center, select "Hardware/CPU and Memory", click "Advanced Settings", and change Hypervisor from Parallels to Apple.

Please, please don't get mad at us about these problems. We did not cause them.

As I don't visit this forum frequently, I missed this before upgrading. Are you working on a fix for this? Do you need a crash log?

For what it's worth, I noticed that after upgrading to macOS Big Sur a few weeks ago that the kernelmanagerd process was running significantly all the time (ca. 50% CPU). I just manually removed the 3 kernel extensions that I believe are associated with the National Instruments drivers (ni488k.kext, nipalk.kext, and NIViPciK.kext) and rebooted, and now the fans have stopped spinning and the kernelmanagerd process is no longer showing up at the top of the Activity Monitor process.

It is not our fault when Apple breaks things. And I mean BREAK: my main Mac has been completely inoperable now for 3 days, the consequence of following a "Senior Advisor" recommendation after the 11.4 update.

We are not a big enough company to navigate these kinds of problems. Neither, apparently, is National Instruments, a billion dollar corporation, whose drivers were broken in the 11.4 update. It is these broken drivers that cause Isaac/Mac to crash.

The only "fix" for the macOS 11.4 fiasco right now is a workaround for Parallels VM, which allows Isaac/Windows to run on 11.4. As an aside: as part of getting Parallels to work again, I needed to update Isaac/Windows to 5.1. It was a one-click update.

Microsoft has figured out how to make things "just work".

Apple has forgotten; they are now where Windows was 15 years ago.

I support John's comments - stuff happens - but of late it is stuff that Apple does and not the vendors who are at the whims of what gets changed by Apple.

Years ago it was all the small features that individuals could create that appeared to enhance functionality of Apple software - yet when implemented - these features (extensions) adversely interacted and caused CONFLICTS with either other "toys" or the operating system (recall Conflict Catcher?)- now in an effort to stop many applications from the most remote security leaks, Apple changes aspects of the OS to tighten system security - and many of these changes lead to user applications crashing - without the capability of testing before the introduction of the changes. The control of how the system operates is actually better than the Microsoft Windows environment - because of their business practices. But there is a reliance on primary developers to be prepared.

The reliance of these vendors on other software (as in National Instruments - who support a number of applications to talk to instruments such as the PowerPod) - where they are either caught off guard or do not staff sufficiently their own support to have already updated their own "flawed" applications or system components.

In the case of National Instruments - they do have a MacOS following, but the support that they provide to respond to Apple changes is less than optimal. Part of that is the products that they provide to the community are not economically critical (insufficient users) to warrant preparation for these Apple OS updates. You can go to their forums and see that the Mac community is vulnerable to National Instrument economics and commitment to Macs.

It is not a fault of Velocomp - and any irritation should be directed at National Instruments.

Well...I am very unhappy with Apple. Apple broke two critical apps, and God knows what else is going wrong with other third party software.

I just found out about the crashing of Isaac with macOS 11.4, unfortunately after the update happened automatically on my Macs. I found a potential way to reverse the update, simply by restoring the Mac using Time Machine backup. See https://www.chriswrites.com/how-to-down ... -of-macos/
Anyone tried this yet?

I don't check the forums often, but just found this thread after Isaac crashed on loading. Bummer. I just got my PowerPod back from service. Will I be able to transfer my profiles from the Powerhouse App? If not, I'm not sure how to proceed.

The route I am taking is to use Parallels VM and Isaac Windows.

If using parallels, would I need to buy a license of Windows to run Isaac?

Good question -

On order to install Windows through Parallels you will need to enter a valid license key code for Windows - perhaps you have a PC that was running some version of Windows ---

When Windows 10 came out, I had a PC that was running Windows 7, and I believe another version - where you could apply the key sequence that Microsoft required - to install Windows I also have since found installer images that can be used for Windows and that very same Win 7 key code will work during the authorization for Win 10.


This may not be of much help - as I do not want to describe how you might get around a purchase of the operating system. But I have seen prices around $35 or less for legal keys.

Nevermind, I just googled it (should have done before my post). I'll get something worked out.

If I do so, can I use the same ride and profile files I used on the Mac side?

Isaac handles the PP ride data the same regardless of computer operating system.

I have had both Mac and Windows versions and both yield the same results.

I have an M1 MacBook Air running OSX 11.4 with Parallels Desktop ver. 16. I have tried the fix suggested but my Control Panel doesn't have the Hyperviser option suggested, as seen below. Do you have any suggestions?

Thanks

You can try clicking the "Adaptive Hypervisor" option.

Unless this happens to work, sadly, Isaac does not run with the M1 CPU. There is nothing we can do about this at this time.

Let us know what you find.

Changing the Hypervisor state doesn't appear to have any effect. I get this message regardless. I guess I will have to wait for a fix for either Parallels or Big Sur/M1.

Thanks, Bill
