Hello everyone. I do tech support for a large railway company based in the USA. From time to time I noticed a considerable amount of calls with users on Mac computers that need to access an IBM Mainframe emulator. Only problem, for both PC's & Macs, is that it runs the MS Java Virtual Machine not the Sun Microsystems Java standard. For the Emulator to run PC's must install & provision the MS Virtual Machine; and disable the Java (SUN). For Macs running OS X; well there isnt a solution directly; users need to install OS 9 then launch IE 5.1 (the last edition I believe). Most users arent savy at WinXP; but most are purplexed why they need to install OS 9; let alone where to find the OS 9 installation discs. I feel powerless to help because I dont, never had the priviledge to, own a Mac. Most importantly I've noticed even with an Apple Store rep on the phone with a user trying to troubleshoot, that the Mac Mini PPC based cpu's cannot run OS 9?? Is this correct? My next major question is .... can a user owning the iMac, MacBookPro, Mac Mini based on Intel Core Duo cpu's install OS 9 and run Internet Explorer from within to get that MS Virtual Machine support???! 1st link http://www.bnsf.com/webconnect/help/requirements.html 2nd link (directions) http://www.bnsf.com/webconnect/help/about_Mac.html Can anyone test this please, and post back? Thank you!
