The video quality lags on my mac when i play starcraft, how can i fix it?

I was pretty disappointed when I couldn't play a 12 year old game on my new macbook either. The best thing to do is go to battle.net, load up the CD key and then load the software onto your mac. The downside is that you will need internet access before playing even if you play single player. That's the way I got around it.

run defragmenter for possible bad cluster on your hard drive, and try to update you antivirus / malware software for possible attack.

A replacemnet video card would help some, but you still have the problem of the 440 mhz processor.

There is not a lot you can do about the processor outside of rebuilding the whole computer. If for some reason that is not an option for you, then yeah, a $20 video card from ebay might give some relief (if you know what to get.. AGP or PCI), but don't be surprised if your processor is just too taxed to render high quality video at the proper rate.

this question isn't so comprehensible ..
first of all, if you doesn't have the original CD with starcraft go to http://starcraft.theabyss.eu/ Here you have starcraft kit to download and servers where you can play for free

Hey.
1. Switch off your antivirus software.
2. Locate the folder(s) mentioned in error message, click with right mouse button on them and then untick "Read only" checkbox (choose second option in next window).
It works fine for me under Win XP (SP3)
