hi,Your problem seem like there is not enough memory or disk space on the internal hard drive for operating since you doing a lot of data on excel.click on the apple menu --->> about this mac -->> more info --->> storage tab --->> let me know how much available space you have left? if you have less than 1GB of hard drive space then you might need to buy an external usb thumb drive and backup some of your data like music, video and picture to free some space.also, go to link below and make sure you install all available update.http://www.microsoft.com/mac/downloadsPlease let me know if there is still any issue. Thank you.If you would like any additional information or have more questions please don't hesitate to ask by reply in here.
104.65 GB free of 188.48 GB
click on the memory tab, how much memory did you installed on your system?
And I have 4GB of memory installed (2, 2GB each)
what you can check to see how much memory your system using, on spotlight search, type in activity monitor
open activity monitor, click on the system memory tab
1.3 GB free
what you can do to test and see if the office software is your problem or the memory,continue to used excel minimize the window screen so you can see both excel and activity monitor screen.. when excel crashed check the activity monitor see if the system memory is peak out or not
Ok....if it is the system memory do I need to go with 8GB memory?
and if not?
since memory are cheap, i would recommend upgrade to 8gb, so you dont have to worry it anymore
