There is only one type of acceleration in Mac version of AutoCAD - Hardware, so you can not disable it.
Although acceLeration option of -3DCONFIG command shows both options - Hardware and Software, the last option is only for compatibility reasons and does nothing on Mac.
I'm just curious how did you perform such task: copy data from AutoCAD for Windows (2004) and paste it to AutoCAD for Mac? Does clipboard on your Mac allow such operations - I mean AutoCAD specific data exchange between virtual machine and Mac OS? I'm assuming that you run AutoCAD 2004 inside virtual machine on your Mac.
I mean that i opened up the .dwg file that was drawn in windows 2004, inside mac lt......and copied from that file, pasting into a new drawing file.....
I see... In fact, when you copy data (AutoCAD objects) from one drawing to another some settings (AutoCAD system variables), specific to the initial file (2004 version file in you case) are not transfered to the new file, as they are stored in each DWG separately. Maybe the case is in these settings? Can not say for sure.
I just now remembered one more thing.
Do you have a lot Layer Groups (Layer Filters as they named in Windows version of AutoCAD) in your 2004 drawings?
Large amount of Layer Groups could considerably degrade performance of AutoCAD.
Look at Layers palette. Do you see a lot of Layer groups?
BTW: AutoCAD can ask you about deleting Layer groups, when you open file that contain a lot of them, but you have to set variable LAYERFILTERALERT=3 in order to see this warning:
In your model space view make sure to set your view to 2d wireframe. If this is set to Wireframe or something else it will lag bad.
