Hey there, pretty new to owning a Macbook Pro here. I have a small issue... I recently tried to buy Microsoft Office for my Mac as a digital download copy. When I downloaded the file it saved as X18-08827.dmg and X18-08827.dmg.part Now every time I tried to open the download to install it (the .dmg file) it says it has 0 bytes and it is not recognized. I try to open the .dmg.part file and it doesn't work either. So I just deleted both files. Now whenever I start Firefox and close my browser when I am done on the internet the damn .dmg.part file somehow comes back from my trash bin and sticks itself onto my desktop. I've deleted it and I have to force quit Firefox in order to properly empty the trash bin to get rid of the file. What is going on? Why does it keep coming back? Was the file somehow corrupt and now is stuck on my hard drive? Sorry if this question isn't well explained or in the wrong forum section. If i can't resolve it myself I guess I'll have to venture all the way to the Apple store and see if they can fix it. Thanks!
