desperately hoping somebody can help figure this out,i would like to have it fixed so i can edit my video and photos without problem ,si have a mid 2010 21.5 inch mac and sometimes when I'm uploading a video to youtube or Facebook or even when i am doing panoramas in photoshop my computer either freezes up so i can't do anything or it tells me there is not enough ram(memory) to completely fill the panorama,I'm wanting to know if you can tell me what may be wrong with my computer?i did install 2 4 gig memory cards to go with the already ones that are in here and it did not make a difference,thank you for any help you can give,my name is Lou
