So I just got a mac...

I noticed I can only đăng tải 5 hình ảnh at a time on a mac. So I investigated and saw that someone đã đăng an article, complaining about this, 2 years ago. Has the problem still not been fixed?
And every time I try to đăng tải a gif to the fanart category on a spot, I get redirected to the fanpop homepage. Does this too have to do with the fact that Adobe sucks when it comes to macs?
