Hi

My company has given me a Mac Pro M2 for development work. ACS is running on a Windows Parallel partition on the Mac. ACS is constantly crashing on the 5250 emulator, which is a pain. I've tried playing with the settings on the menu's, but nothing seems to help. My colleague who is also using a Mac Pro M2 is having the same problem.

Does anyone know what settings would prevent this?

Thank you.

Hi Neil

Just out of curiosity, why run IBM i ACS on a VM with Windows for ARM (not x86), when you can run ACS perfectly on native MacOS ??

I don't think there has been much testing of ACS on Windows for ARM - if any at all.

Remember Apple CPUs M1 & M2 are ARM processors, not x86 like used in previous Apple Macbooks.

Hi Janus

Thanks for your reply. You're absolutely right - my mistake, I am running ACS natively on MacOS. The problem is still occurring.

I've recently joined and work with Neil, and I to experience the ACS 5250 emulation crashing, my Processor is an Apple M3.  Unfortunately it happens extremely regularly and most days it's unworkable :(. It's easy to replicate for myself, simply scroll quickly through a source listing or a subfile page (like WRKACTJOB).

Hi Neil

Sorry to hear you still have issues with ACS and 5250 emulation on your Mac. 

Please verify that you are using the latest version of ACS (currently 1.1.9.4). 

Download from here: https://www.ibm.com/support/pages/ibm-i-access-client-solutions

If your problems continues, I suggest you open an IBM support case for IBM i ACS at https://www.ibm.com/mysupport/

Dear Andy

One important factor for run-time stability of IBM i ACS is the Java engine. Since you are using Java engine from Oracle, I suggest you change it to install IBM Semeru JDK for MacOS and use it for IBM i ACS.  The latest release of IBM Semeru for MacOS is 21.0.2.

I've recently joined and work with Neil, and I to experience the ACS 5250 emulation crashing, my Processor is an Apple M3.  Unfortunately it happens extremely regularly and most days it's unworkable :(. It's easy to replicate for myself, simply scroll quickly through a source listing or a subfile page (like WRKACTJOB).
